*Nominal BTU based on gas inlet pressure. Nominal gas inlet
pressure for natural gas is 5” W.C..
Required Gas Pressure:
The minimum inlet gas supply pres-
sure for the purpose of input adjustment is 5” of water column
(w.c.) for natural gas. The maximum inlet gas supply pressure
is 10.5” w.c. for natural gas. The minimum inlet gas supply pres
-
sure for the purpose of input adjustment is 11” of water column
(w.c.) for propane gas. The maximum inlet gas supply pressure
is 13” w.c. for propane gas.
Testing the Gas Supply System:
The gas fireplace and its
required individual shut-off valve must be disconnected from
the gas supply piping system while performing any tests of the
piping system at pressures in excess of ½ psig. The gas fire
-
place must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal
to or less than ½ psig. This is accomplished by closing the gas
supply line valve required by NFPA 54.
A fireplace screen must be replaced after service and be in
place when the appliance is in operation and, unless other
provisions are provided, the screen shall have an opening(s)
for introduction of combustion air. When glass fireplace doors
are used, operate the gas fireplace with the doors open.
