2.2 GAS SUPPLY
The boiler requires a gas rate of 2.4 kg/h (5.3 lb/h) or 4.7 litres/h of liquid gas.
The supply pipes must be capable of delivering this quantity of gas in addition to the demand from any other appliances in the
house. The boiler requires at least a 22 mm gas supply pipe.
The complete installation must be tested for gas soundness against leakage.
The local Propane gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an
adequate supply of gas.
Installation pipes, cylinders and pressure regulators should be fitted in accordance with BS 5482:1. Bulk tank installation must
comply with the requirements of the Home Office code of practice for the storage of liquefied petroleum gas at fixed
installations.
3 BOILER LOCATION
The boiler must not be installed in a room or internal space below ground level, e.g. in a basement or cellar, except where at
least one side is open to ground level.
