INSTALLATION

36 GAS CONNECTION

Refer to 'Gas Supply ', page 8.

Refer to Frame 2 for gas inlet service dimensions.

Aminimum pressure of 20 mbar MUST be available at the boiler inlet with the boiler operating. The main gas cock is on the left hand side of the gas control valve, as shown. To facilitate connection the gas cock may be removed from the gas control valve.

37 WATER CONNECTIONS

1.Remove the plastic plugs from the flow and return pipes.

2.Make all water connections and check for water soundness.

38 CONDENSATE DRAIN

Refer also to the British Gas document: 'Guidance Notes for the Installation of Domestic Gas Condensing Boilers' (1989).

The boiler comes with a built in condensate siphon trap. The boiler condensate drain must be connected to a drainage point, preferably within the building. This condensate drainage should be run in standard 21.5mm overflow pipe. Connection to the boiler is made by fitting the siphon nut and sealing washer to the threaded siphon outlet.

Ensure that the condensate siphon is full of water before commissioning the boiler. Refer to Frames 19 and 27.

The routing of the drain must be made to allow a minimum fall of 1 in 20 away from the boiler, throughout its length.

The drainage pipework must be arranged so that obstruction (e.g. through freezing) of external drainage pipes does not give rise to spillage within the dwelling.

If excessive external pipework cannot be avoided a condensate removal pump (available as an option) and insulation are recommended to prevent possible freezing.

All pipework and fittings in the condensate drain system must be made of plastic. No other materials may be used. The drain outlet on the boiler is standard 21.5mm overflow pipe. This size must not be reduced in any part of its length.
