This part of BS 5871 specifies installation requirements for flued and flueless fixed space heating appliances burning 1st, 2nd and 3rd family gases for the purpose of heating rooms or spaces in domestic or commercial premises. It applies to appliances known as radiant gas fires, radiant convector gas fires, convector heaters, and heating stoves. Convector heaters in the form of greenhouse heaters are only covered in respect of single appliance installations. Combined appliances of the type where a gas fire is used in conjunction with a boiler or circulator are also covered in so far as the installation of the combined appliance is concerned.
This standard covers the selection of a suitable appliance, the ventilation and flueing requirements, and other measures necessary to ensure a safe installation.
The central heating and/or hot water system connected to a combined appliance is not within the scope of this standard and reference should be made to BS 5449 and BS 5546 for this part of such an installation.
This standard is not applicable to mobile and portable appliances conforming to BS EN 449 or to appliances in touring caravans.
The requirements for the installation of fire/back boilers and fire/back circulators are also specified.
