•Connect the gas supply pipe to the isolation tap and check for gas
soundness.
•Record details in the commissioning sheet on page 21
Commissioning the Fire – Gas Connection
•Connect a pressure test meter to the inlet test point fitted to the
isolation valve within the fire.
•If you are not familiar with this style of manual ignition system please
consult the instructions on page 33 “Lighting the fire”.
•The first time the fire is operated it will take some time to purge the
air from the line.
•Light the Fire and set the fire on the “maximum” heat setting.
•Leave the fire running for 10 minutes to ensure the flue and the
appliance are at working temperature.
•There will now be a series of pressure tests to ensure the appliance is
operating correctly and safely. The inlet must be within the allowed
tolerance of +/- 1mb of the working pressure as stated on the Data
Plate. For example in the UK, Natural Gas (20mBar) can be 19 to 21,
LPG (37mBar) can be 36 to 38. On each test the results must be
recorded on the commissioning sheet on page 21.
•STAGE-1 - Ensure all other gas appliances in the property are off and
check the manometer reading.
•STAGE-2 - Now turn on all the other gas appliances in the house on
and check that the pressure still remains within the tolerance of +/-
1mb.
•STAGE-3 - Now turn off all the other gas appliances and turn the fire
down to pilot only and check that the still remains in the tolerance of
+/- 1mb.
IF PASSED : Disconnect the pressure gauge then replace the pressure test
point sealing screw and test for gas soundness. Continue with the installation.
IF FAILED : If the appliance fails the above test it must not be used until
either the gas pipe work to the appliance has been improved or the governor to
the house has been adjusted by TRANSCO, BORD GAIS or the propane supplier.
Running this type of appliance with incorrect gas pressure can result in harmful
emissions being released into the room.
