any pressure testing of that system at test pressures in excess of 1/2 psig. For pressures under 1/2
psig, isolate the gas supply piping by closing the manual shutoff valve.
•
Leak test all gas line joints and the gas control valve prior to and after starting the fireplace.

Fuel
•
This fireplace is designed either for natural gas or for propane (but not for both). Check the sticker on the top of
the gas control valve to make sure the correct fuel is used (see illustration on page 4).
Gas Line Connection
•
Installation must be performed by a qualified installer, service agency or the gas supplier (In Massachusetts
a licensed plumber/gasfitter).
Gas Inlet Pressure
Standard Input Pressure
Natural Gas 7" W.C. (1.74 kPA)
Propane 13" W.C. (2.73 kPA)
•
If the pressure is not sufficient, make sure the piping used is large enough, the supply regulator is
adequately adjusted, and the total gas load for the residence does not exceed the amount supplied.
•
The supply regulator (the regulator that attaches directly to the residence inlet or to the propane tank) should
supply gas at the suggested input pressure listed above. Contact the local gas supplier if the regulator is at
an improper pressure.
