STARTING THE GAS FIREPLACE
Starting the gas fireplace
Learn how to start up the gas fireplace after installation in this section .
Pressure test
The fireplace is pre-set to provide the correct amount of heat (kW), which is described under the specifi-
cations . There is no need for further adjustments . “Inlet pressure” (supply pressure to the gas block) and
“Burner pressure” (nozzle pressure) must ALWAYS be measured and if necessary, corrected by an author-
ised heating and plumbing and gas installation technician .
1 . Close the gas valve (Main Valve Knob)
2 . Open the “Inlet pressure tap” on the gas valve and connect a manometer .
3 . Check the measurement agrees with the pressure stated on the information plate .
4 . Carry out a test of the fireplace at full power including the secondary burners, and when the fireplace
only has the pilot flame lit .
5 . If the pressure is too low, check the size of the gas supply pipes to ensure this is correct .
6 . If the pressure is too high (more than 5 mbar too high) the fireplace can still be installed but the gas
utility company must be contacted .
7 . Loosen the screw to the “Outlet pressure tap” on the gas valve and connect a manometer .
8 . Check that the measured pressure agrees with the pressure stated on the information plate .
9 . The measured value must be within ± 10% of the stated pressure . This is not the case, contact the
supplier .
NB: After the pressure test is complete and the manometer has been removed, re-tighten the “pressure
tap” screws . Check the system for gas leaks .
Mark off the gas type on information plate on the fireplace . It is either natural gas, propane gas or town
gas .
