2. Remove the pressure test point sealing screw and connect a
pressure gauge (Fig.6).
3. Turn on the gas service tap (at present supplying gas to the
boiler only) fully anti-clockwise. The service tap is now supplying
both the boiler and the fire (Fig.4).
4. Purge the air from the gas supply pipe and check for gas
soundness (BS 6891).

the control knob to the OFF position fully clockwise and repeat.
6. Check that the fire burner lights smoothly by pushing in the
knob and turning fully anti-clockwise. Test for gas soundness
with leak detection fluid.
7. Check the fire pressure with the control knob in position 3
fully anti-clockwise. The pressure should be 14.5mbar ±0.5mbar
(5.8 in. wg. ± 0.2 in. wg.).
8. Turn the control knob clockwise to the OFF position (
Remove the pressure gauge and refit the pressure test point
sealing screw, ensuring a gas tight seal.

operated for a further 10 minutes before rechecking.
If spillage is still evident the cause must be
ascertained and rectified before continuing with
commissioning.
(d) Repeat with both fire and boiler alight, having run the
boiler for 5 minutes.
