This is Bytnar Talks the Engineer Takes on Construction Episode 25 hi I'm Piotr Bytnar each day I help my clients plan and design building projects through Bytnar Limited a Consulting Chartered Structural Engineers practice my biggest passion and the cornerstone on which I've built my business is finding clever solutions for construction projects I am a chartered structural engineer and a budding software developer so you can rest assured that I will strive to talk about the best practices and the use of new technologies in the industry and if you're embarking on a construction project or are involved in planning designing and building the world around us you'll find this podcast [Music] useful approv document J compass appliances and fuel storage systems hi and welcome back to bitar talks your favorite podcast on all matters of architecture engineering and construction it is Thursday the 5th of August 2024 and I'm here back with you with the 25th episode and information on approved document J combustion appliances and fuel storage systems we are at the Eve of summer holidays Believe It or Not these episodes are not curated by an army of employees powered by AI so the host meaning I needed a little break I now return back to you from the scotching coast of Italy back to the south of southeast of England country where we can afford outside air conditioning oh sorry it just the weather that is not as nice as our flour tomato sauce and cheese loving friends is is as however before I go to covering the material of this episode let's have a look at what was covered last week in the last episode I talked about the approved document H drainage and waste disposal there are six requirements covered in this document and these are requirement H1 foul water drainage which concentrates on proper capacity minimalization of blockages and leaks access for maintenance and prevention of foul air Ingress or backf flow into the property requirement H2 wastewater treatment systems and cpols tells us that systems must be must avoid nuisances health hazards and pollution with adequate ventilation and access for maintenance as well as the as to Adare to environmental agency guidelines and Bs standards requirement hedge free rainwater drainage tells us that systems should effectively carry water from roofs and paved areas prioritizing soak ways to be used first before anything else then water courses with discharge to sew as the last result we need to think correct sizing to the tributary area and the local rainfall and we need to ensure to provide accessible maintenance points to our system requirement H4 build over sewers treats on new buildings so they do not affect existing drainage obstruct maintenance or replacement or or replace the AIS for for the maintenance also that drainage does not compromise the stability of the structures we are reminded in that section that agreement with the drainage system owner is required requirement H5 separate system of drainage goes on to tell us that separate systems for surface and foul water are necessary ideally directing surface water to soak WS or water cses but should a combination be required that need to be SED properly and agreed with local Authority requirement H6 Solid Waste storage is all about the provision of adequate accessible and verment proof waste storage facilities to prevent health hazards and maintain hygiene ensuring ventilation and weather resistance in this episode I will move to the approved document J combustion appliances and fuel storage systems so without further Ado let's dive straight into [Music] this in this episode I'll talk about the statutory guidance contained within the approved document J combustion appliances and fuel storage systems the episode will follow its standard format for the material talking about the approved documents I will first read you the text of the actual regulation and then we'll go Section by section the document contains guidance for the discharge of requirement J1 to j7 in six sections 0 to five and additional information in appendices so let's get into the Integrity of this approved document starting with the text of the legislation part J combustion appliances and fuel storage systems Air Supply J1 combustion appliances shall be so installed that there is an adequate supply of air to them for combustion to prevent overheating and for the efficient working of any flu discharge of products of combustion J2 combustion appliances shall have adequate provision for the discharge of products of combustion to the outside air now requirements J1 and J2 apply only to fixed combustion appliances including incinerators warning of release of carbon monoxide that's requirement j3 where a combustion Appliance is provided appropriate provision having regard to the design and location of the appliance shall be made to detect and give early warning of the release of carbon monoxide at levels harmful to persons now requirement j3 applies only to fix combustion appliances located in dwellings protection of building that's requirement j4 combustion appliances and flu pipes shall be so installed and fireplaces and chimneys shall be so con contracted and installed as to reduce to a reasonable level the risk of people suffering Burns or the building catching fire in consequence of their use now requirement G j4 applies only to fix combustion appliances including incinerators provision of information does requirement J5 where a half fireplace flu or chimneys provided or extended a durable not noce containing information on the performance cap capabilities of the half fireplace or flu or chimney shall be affixed in a suitable place in the building for the purpose of enabling combustion appliances to be safely installed protection of liquid fuel storage system does requirement j6 liquid fuel storage systems and the pipes connecting them to combustion appliances shall be so constructed and separated from buildings and the boundary of the premise as to reduce to a reasonable level the risk of the fuel igniting in the event of fire in adjacent buildings or premises now requirement j6 applies only to fixed oil storage tanks with capacities greater than 90 L and connected pipes and B fix liquefied petroleum gas storage installations with cap capacities greater than 150 L and connecting pipes which are located outside the building and which serve fixed combustion appliances including incinerators in the building protection against pollution that's requirement j7 oil storage tanks and the pipes connecting them to combustion appliances shell a be so constructed and protected as to reduce to a reasonable level the risk of the oil escaping and causing pollution and B have a fix in a prominent position at durable notice containing information on how to respond to an oil Escape so as to reduce a to a reasonable level the risk of pollution now requirement j7 applies only to fix old storage tanks with capacities of 3 and 12,000 l or less and connecting pipes which are a located outside the building and B serve fixed combustion appliances including incinerates in a building used wholly or mainly as a private dwelling but does not apply to buried systems easy peasy lemon squeezy straightforward stuff isn't it on this occasion as in many other requirements we will find expect expectations that fall outside of the Merit of just providing reasonable protection to the health and safety of people in and about the buildings but on us in regulation put on us in the regulation 8 in this case it is part j7 as it deals with protection against pollution it needs to be noted that the requirement is enforceable on particular types of building work or material change of use and some building classes may be exempt from the regulations you can find the list of classes in schedule two of building regulations having said that building regulations do not stand alone and the gas installation will fall under the gas safety installation and use regulations 1998 some further requirements will come from the workplace health and safety welfare regulations 1992 or under the Clean Air Act 1993 as amended by the environmental act 2021 schedule for of building regulation least the number of works that do not need to be notified to the building control but they work on combustible appliances unless it is not a repair or maintenance will need to be notified to building control in case of anyone want this the standard of the work and use of materials need to be right and proper as need to be the periodical Maintenance and Service before you start dreaming of owning an open fireplace do check if you do not live in a smoke control area in such areas you may be required not to use any Appliance or use an authorized type of fuel or use an exempt Appliance so starting with Section zero it needs to be understood that the approved documents guidance has been prepared mainly with domestic installation in mind and covers combustion installation and its fuel storage systems includ it solid fuels things like space and water Heating units and cookers the installation cover in the guidance are solid fuel installation of up to 45 KW of rated output gas installation of up to 70 kiltons of net or 77.7 kilo kilowatt of gross rated input and oil installations of up to 45 Kow rated heat input output sorry 3500 L of oil storage or 1.1 ton of LPG storage guidance outside of these parameters can be found in charted institution of Building Services Engineers cibb SE guide B and materials produced by the British standard institution and the institution of gas engineers and managers the guidance goes on to address consideration for different appliances used in different ways so it will go by fuel type solid oil or gas Air Supply open fluid say through the background or provided Inlet to the room or room sealed air is supplied direct directly into the combustion chamber through a flu in any case whether open or room seal system the burning can can be also assisted assisted by fans combustion products removal natural drought flu font flu or flueless the drought can be fairly assisted by drought break or diverted or stabilized this section goes on to describe all different elements that may form the installation or consideration for the installation of combustion appliances including fireplace structural recesses with shape and lining may or may not be suitable for all different type of combustion fuels I really like this document as it's full of descriptions and diagrams making it very easy to follow like the diagram six showing a cross-section through the floow containing half or diagram seven that makes show you really but really know that taking the dimension diagonally through flu is not the correct way of doing it now section one starts with telling us that secretary of state is happy if the installation is good and proper in specification material size workmanship and inspection for its safe and good operation and the carbon monoxide alarm is provided for solid and Gas Appliances excluding cookers and oil appliances and provided that any fuel storage of oil or gas is proper and the performance capability of the system is labeled so Air Supply and flow will depend on the type of the appliances requires intake intake number of appliances and the requirement for cooling if needed and it is all nicely shown on diagrams within the documents the par permanent open vents should be well sized taken in consideration their grills and meshing of not less than 5 mm gaps and so located that the occupiers cannot seal them Al so the drought does not become a nuisance to occupier or does not disturb the remainings of combustion the locations of air vents will depend on performance or location of the appliance but care should be taken when there are protective membranes so that their function remains intact things like bre and Vapor cont control membranes in Timber Frame construction or gas barriers from below the ground the approved document shows typical suggestion for the location of such vents we may be able to account these openings for a background ventilation for the requirement F but not the other way around due to a simple fact of the ventilation requiring to be constantly open Purge ventilation will also be necessary in such instances we also need to assure that if the rooms are mechanically ventilated there is not enough of De depressurisation that's the tough one in the room as to back route the combustion products so we don't want to have that reverse suction action on our flu so we so we get suffocated with the with the combustion gases the guidance gives us limits for fun extraction maximums in rooms with different appliances so for gas appliances it is 20 L per second for oil it is either 40 or 20 L per second for pressure jet burner or vaporizing burner and for solid fuel burners the limit is zero unless it can be proven the installation can be safe in operation similarly for commercial installations there may be some extra considerations necessary to make sure proper air and products of combustion circulation Extra Care is also advised where ground gases are ventilated away from underneath the building so they do not recirculate back into the house the guidance directs us to now withdrawn building research establishment good building guide 25 that deals with Raiden and shows us the the particulars of the sort of circumstances the check to assure no back drought or harmful gas pilles needed I will until running the wars the pressurization the pressurization well that's a tough one my leg my tongue isn't capable of doing this one properly of the room scenario using all fs and different arrangement of open to close windows and doors the spillage test may come from Pro proprietary literature or British standards or other Publications like that produced by all oil firing technical Association unless the system is flueless we will need to provide a flu or a chimney separate for each solid burning Appliance but can be combined for other fuels however the guidance only cover single flu or chimney system and references BS 5410 and Bs 544 for oil and gas installations the chimney should not be prone to condensation so for non condensing appliances is best if the flu are insulated to avoid such a normal operation or to be in line with the material appropriate to resist corrosion and such to allow drainage of Co of the condensate masonry chimney should be sufficiently strong thick and of sufficiently dense material with flu line with a liner at least as good as designation T400 N2 d3g to BS n 1443 standard but can also be clay flu or correte liners there is no one good answer here use what you want and what is compatible with your system and meets the standards typically you will be using proprietary products so follow the instructions naturally just to mention the obvious the elements should be joined up correctly using route of high temperature resistance otherwise called fire or refractory cement and the space between the flu lining and the masonry should be filled with a lightly wetted lean mix of cement one part of either 20 parts of lightweight expanded clay aggregate or six parts of vermiculite or 10 10 parts of PE light just for the installation purposes an alternative to using Linus is to use a proprietary flu block system of sufficient designation and durability installed to the manufacturer specification adapting existing chimneys or flu should be done with due consideration to its current state and condition of repair connection type and material and instulation from other elements of the building flu are controlled services and the introduction of a new flu liner or replacement of such will require notification to building control metal liners should be replaced together with the Appliance and the flexible liner cannot be used as p as a primary liner you can use plastic flu pipes to bn1 14471 appropriate for the appliance type and fuel when it comes to factory made metal chimneys this need to follow standards applicable to the type of of the fuel used perforation of walls and flows plates as well as heated related consideration for the detailing of the installation should be considered such as distance away from the flu as described in BSN 81856 the joints of these flu need to be serviceable any concealed flu should be accessible for inspection with access hatches of at least 300 mm squared not further than 1.5 M away from the joint or a band natural drought flu serving open fluid appliances should be ideally ver vertical with no bends discounting the outlet from the appliance which should be no further than 150 mm millim from the appliance max four bends of Maximum 45° are allowed where 90° angle pro pro proprietary Appliance Outlet accounts for two of these access for inspection and sweeping should be provided every two bends we are reminded that low level out may be disrupted in future due to neighborly extensions but dread not as the guidance comes with a diagram for appropriate location how would it do it otherwise right those documents are brilliant we are also informed to avoid creating voids near the combustion appliances to which gases could Escape things like decorative dry lining surround which should have such gaps well SE well sealed the responsibility to discharge requirement J lays with the person executing the works reports stating the elements of the installations are suggested in appendix a of the document and test to the guidance of appendic e should be collected and ready for submission to building control the installation should be free from obstruction gas tide of proper materials and workmanship spillage tested during commissioning for part L compliance Hales should be of the right size and material the information about halfs fireplaces flu and chimneys need to be permanently posted in the building to avoid misuse so information on their location size category make suitability and installation date example of notice is provided within the document position of such plate should be such it is readily accessible so places like a consumer unit next to stopcock or next to the actual chimney will do just fine roof space installed gas fired appliances should follow now withdrawn BS 6798 specification for installation and maintenance of gas fired boilers of rated input not exceeding 70 Kow net now we we will move to section two which extends on the information provided in section one concentrating on appliances burning solid fuel including biofuel with a rated output up to 50 Kow Air Supply to these beasts need to follow the minimum consideration but may require more depending on the type of Appliance and the type of fuel used checking the manufacturer specifications all the table in the approved document would be the point at which we should start the consideration for example an open fireplace under a canopy or with a throat requires a fresh air supply of at least half of the exhaust capacity meaning half of the flu in the case of the canopy Offroad it will not be of surprise but the flu also needs to be of appropriate size and run starting at the size of the Appliance Outlet or it can be looked up in the documents tables so for example for fireplaces we start at 200 mm diameter size or equivalent and for close appliances we start that smaller from 125 mm diameter flu large opening fireplaces should have a flu of at least 15% of the total face area however should the size be larger than 0.12 M squared or exceed the 15% limit we are encouraged to seek specialist advised we are guided in the subject of flu height that should be high enough to develop sufficient drought the figure will depend on the type of Appliance number of bands and local wind pattern but we start at 4 and 1/2 M High we can calculate the actual requirement using a procedure within BN 13384 a standard that deals with thermal and fluid Dynamic calculation methods for chimneys the height is measured either from The Appliance Outlet or the point where exhaust cases enter the chimney the flu Outlet position should also be considered we cannot just plun it anywhere on the roof it needs to be positioned so the exhaust gases can freely dis disperse in the air the document comes to help with a handy diagram but the gist is simple there are three distances to consider 600 mm 1,000 mm and 2.3 M 2.3 m is a horizontal distance to any other roof feature protrusion other puzzle buildings other buildings or Windows in most cases the outlet should be at least 1 m in height but will likely need to be either as high as the rid 600 mm higher than the ridge or the adjacent feature if close to the ridge or the feature or at least one m above the opening that is for typical roofs but should the roof be made of readily ignitable material the outlet needs to stand at least 1.8 m tall generally but at least 600 Mill above the ridge level for a distance up to 2.3 M away from the ridge touched roofs attract further consideration of temperature insulation between flu and the touch connecting flu pipes are just that connections of Appliance with the chimney should should be proper and not hidden Within buildups the distance between them and combustible materials should be at least three times their diameter and if they need to be closer then the distance can be reduced to 1.5 times the diameter given a non-combustible shield is installed to a distance at least 1.5 times the diameter in all directions the document requires at least 12 mm air gap between the combustible material and The Shield the flu should be serviceable and have an accessible debris collection feature masonry cheeves should be at least 100 mm thick in general but 200 mm mm between other properties or other fire compartment combustible material should be at least 200 mm away from the inside of the flu or the restes or 40 mm from the face of a masonry chimney or fireplace unless it's a wall or floor finish like a skirting board or a mantle piece metal fixings however can be as close as 50 mm to the inside of the flu liner it is all about the heat dispersion through the material and what effect it may have on the combustible materials the guidance also tells us that open fire pit should have gathers that lead smoke to the flu at an angle no less than 45° and that half should be of appropriate size and material selection of which will depend on the heat dispersion of the appliance for example appliance that do not give away more than 100° Centigrade from below it may be the the half requirement may be as little as 12 mm thick tiling but for structural half we talk of a minimum starting at 100 25 mm diagrams containing contained in the document nicely convey all the geometrical constraints for all different type of appliances from open fires to low heat output it is important to monitor air quality in the room containing an appliance that burns Fuel and the way to do it is by a car carbon monoxide alarm in line with BSN 50291 either battery or main power located 1 to 3 m away from the Appliance on the ceiling 300 mm away from walls or on the wall at least 150 mm away from the ceiling path over doors and windows openings when the half and Appliance is placed close to the wall within 50 mm the wall needs to be thick at least 200 mm and be at least 1.2 m above the half and at least 300 mm above the appliance when the appliance is further away but not further than 300 mm the thickness of the wall goes down to 75 mm when the half detaches from the wall up to 150 mm we need to provide minimum thickness of the wall of 75 mm but further away there is no such requirement anymore I do strongly suggest you guys have a look at the diagrams within the document these are very very good and clear now section three expands on the provisions of section one considering gas burning appliances with a rated input of up to 70 kilowatt net I could simply say do not worry just get an appropriately competent installer registers on a gas safety register firm or a person involved and let them do the magic as undoubted undoubtedly that is what the approved document ask you to do when it comes to gas installations the gas safety installation and use regulations is the piece of legislation that furly covers the subject in general appliances fitted in the room where people sleep or bathe should be of room sealed type there are numerous different Gas Appliances including cookers room heers decorative fuel effect fires inant light fuel effect fires and each will come with their requirement for for Air Supply and or change of the air in the room when the products of the combustions are released into the room the basic limits for the minimum provision of open air vents will depend on the type of Appliance whether open fluid or room sealed free standing or enclosed within a compartment within the room and then the compartment being either ventilated through the room or to the outside air similarly for the consideration of flueless gas of appliances there are limits given within the document going by the type of the appliance each heat input the volume of the room and the free area of permanently open nents the size of flu follows similar consideration of section two so the gas appliances imitating fireplaces the flu diameter will start at 175 mm and for radiant or convector gas Fires at 125 mm the high of the flu these days usually follows the manufacturer specifications for older installation we may need to go back to Old standards or we may need to calculate it the location of the outlet for the combustion gases is not as stringent as the one for solid fuel Burns nevertheless we want to minimize the impact of a gas plume leing our building there is too many places where we can place the outlet on our building to tell you all here they do take two pages of A4 one for the text and the other a diagram so do check it out for further information the distances are generally somewhere between 300 mm to 2 m for a roof in situation close to the boundary or the roof window the penetration of the outlet should be at least 600 mm to the sides and top of the opening and 2 m and the guidance provides a warning that the locations of the condensing boiler Outlets even though fined under building regulations may be of a nuisance to our neighbors under the Environmental Protection act and should be perhaps as far as directed in the Gap and should be and we should search for the further guidance in the guide to condensing boiler installation assessment procedure procedure for dwellings naturally the flu outlets need to be protected from blockages and tampering properly selected and installed the requirement the requirement for the provision of a carbon monoxide alarm follows from section two now off to section four which deals with additional Provisions for oil burning appliances with a rated output up to 45 kilow in cons cons it considers appliances that burn kerosene and gas oil class C2 and D to BS 2869 or liquid biofuel to en 14213 or blends of fuel the provisions for location ventilation and outlet location follows that for gas appliances albate ever so slightly differently so do not assume that's the same go and check the tables and diagrams in the document the Secretary of State in this approved document is concerned about the temperature of gases traveling within the flu most appliances should be Pro should produce exhaust gases well below 100° Centigrade but we are advised to check the manufacturer's literature and in doubt over the lack of information we should think of gas temperature in excess of 250° in line with the need the chimney should be lined with material of appropriate designation similarly to other section halves and Provisions for Gathering oil spills should be made at as necessary as is the provision of carbon monoxide alarms section five deals with Provisions for liquid fuel storage and Supply in the Gs the oil and LPG units and their installation should be so located and construction constructed to avoid their damage especially during a building fire or fire close to the boundary and are labeled with information on how to deal with leaks there are are certain limits of the size of installation that this document covers and these are different for the protection of the storage and different for environmental concerns especially where the tank serves more than a dwelling if in doubt the Fire Authority can be consulted and the control of pollution All Storage regulation 2001 may need to be read so the protection of oil tanks will consist of a solid concrete base to start with then we can either enclose it with a special fire haard room or if it is closer to the building than 1.8 m we should either make a building imp perforate for fire for at least 30 minutes or provide a barrier either way such constructed Shield free standing or as a part of a building should extend 300 mm Beyond any side of the tank if the tank is less than 760 mm from the boundary we will need to construct a fire of 30 minutes fire resistance if the tank is at least 1.8 m away from the building and at least 7 60 mm from the boundary the concrete slab alone will do just fine for the oil supply pipes in this should be robust and fitted with fire valve system for the control of pollution secondary containment may be required where there are positions so there is a significant risk of oil pollution this will be either by means of integrated or constructed bands in any case an information should be attached to the tank with instruction of what to do in case of leak and the telephone number to the environmental agency the LPG storage tanks will be controlled by the health and safety executive but small installation of up to 1.1 ton can be done following the guidance of the approved document we are referenced to UK a LPG code of practice one bulk LPG storage at fixed installation part two and Bs 5482 besides this guidance in simple terms tanks should be in well ventilated spaces away from sources of heat and buildings and one firewall can be provided of 30 minutes fire rating or 60 minutes if it forms part of the building if the tank is fre m is away from the building all the boundary no special considerations are required but if it gets closer to any one of them we are assisted with handy diagrams in approved document LPG is heavier than air so we need to make sure if the tank leaks it does not leak into the into our basement cellers or drains smaller bottles of gas can be located close to the buildings but there are as ever minimum distances required away from those wind Windows drains Etc pipes laid underground need to be corrosion proof but the pipe entering the building should be above the ground metal and sleeved any pipes run in shaft duct and voids should be ventilated now all there is to do is to fulfill the checklist from appendix a follow procedures from appendix e and give it to building control and the client [Music] so this is it folks the approved document J combustion appliances and fuel storage system let's sum it up section by section section zero gives us the scope and standards for consideration the approved documents primarily focus on domestic installations and cover combustion and fuel storage systems including solid gas oil installation with specific output limits in the text we are further directed to seek guidance in CIBC guideb and materials from BSI and IGM section one gives us General Provisions for safe installation which includes proper specification material size workmanship and inspection adequate Air Supply ventilation and proper flu systems are essential for the good operation of the system specifically requirements include carbon monoxide alarms for combustion appliances and correct half sizing heat insulation and material selection proper documentation and compliance testings testings are mandatory section two as to the basic regarding solid fuel appliances up to 50 kilow output which require appropriate Air Supply flu size and flu height flu Outlet positions and distances from comb Buble must be carefully considered clearances from walls and half specifications vary depending on Appliance type and proximity to other combustible and non-combustible materials section three adds consideration for gas appliances up to 70 kilow net input must be installed by a gas safety registered professional room sealed appliances are recommended for sleeping or bathing areas ventilation and through flu requirements vary by Appliance type considerations for Outlet positioning and potential nuisance are made section four adds information on oil burning appliances up to 45 Kow output and follows similar guidelines to Gas Appliances but with specific Provisions for all types and blends considerations are made for flu gas temperatures and its acidity as well as that for positioning and half materials the document emphasizes checking of manufacturer specifications section five oil storage and LPG storage must be protected from fire and environmental damage proper installation secondary containment and labeling for emergency procedures are required fire resistant barriers or walls might be necessary based on proximity to buildings and boundaries slam guidance on underground and above ground piping is provided in the next episode we will move to the approved document K protection from falling collision and [Music] impact I hope you enjoyed this episode and that the considerations of the approved document J combustion appliances and
