2.3 Connect the Gas Supply
1. Ensure that the gas supply is isolated.
2. Disconnect the gas cock from the gas valve.
3. Connect the gas supply to the gas cock
using a suitable adaptor.
Important:
Do not solder the fitting whilst
assembled to the gas cock.
The pipe diameter required will depend on
the boiler model and the pipe length from
the gas meter. Ensure that the gas supply
pipe is selected in accordance with BS 6891
so that an adequate gas supply to the boiler
is provided.
4. Connect the gas cock to the gas valve.
Do not turn the gas supply on at this stage.
2.4 Connect the Water System
When attaching the standard pipe connecting kit to the boiler please note that the seal is made by use of an 'O' ring,
therefore some pipe movement will be evident even though a water tight seal has been achieved. Excessive force is
not necessary and could result in damage to the appliance.
1. Connect system pipework to the boiler, compression fittings should be used. Arrange pipework to ensure correct venting
of pipes and boiler. On gravity systems a tee is required in the flow which must be fitted directly to the connecting pipe
supplied. Note: Drain off taps should be installed at the lowest points in the system.
2. If on a Gravity DHW system position the overheat thermostat as shown.
3. To do this - unscrew the overheat thermostat from the flow pipe and re-attach as shown using the bracket and screw
found in the tail pipe/gravity stat kit.
