9 Approved Document J Combustion appliances and fuel storage systems O N L I N E V E R S I O N Requirement Limits on application 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 flue. Discharge of products of combustion J2. Combustion appliances shall have adequate provision for the discharge of products of combustion to the outside air. Warning of release of carbon monoxide J3.
Where a fixed combustion appliance is provided, appropriate provision shall be made to detect and give warning of the release of carbon monoxide. Protection of building J4. Combustion appliances and fluepipes shall be so installed, and fireplaces and chimneys shall be so constructed 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. Provision of information J5.
Where a hearth, fireplace, flue or chimney is provided or extended, a durable notice containing information on the performance capabilities of the hearth, fireplace, flue 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 systems 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 premises as to reduce to a reasonable level the risk of the fuel igniting in the event of fire in adjacent buildings or premises. Protection against pollution J7.
Oil storage tanks and the pipes connecting them to combustion appliances shall: (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 affixed in a prominent position a durable notice containing information on how to respond to an oil escape so as to reduce to a reasonable level the risk of pollution. Requirements J1 and J2 apply only to fixed combustion appliances (including incinerators). Requirement J3 applies only to fixed combustion appliances located in dwellings. Requirement J6 applies only to:
(a) fixed oil storage tanks with capacities greater than 90 litres and connecting pipes; and (b) fixed liquefied petroleum gas storage installations with capacities greater than 150 litres and connecting pipes, which are located outside the building and which serve fixed combustion appliances (including incinerators) in the building. Requirement J7 applies only to fixed oil storage tanks with capacities of 3500 litres or less, and connecting pipes, which: (a) are located outside the building; and (b) serve fixed combustion appliances (including incinerators) in a building used wholly or mainly as a private dwelling, but does not apply to buried systems.
