Important Pre-installation Information
Before you begin
, review the information and safeguards
below regarding the installation and operation of the gas
fireplace.
This fireplace may only be connected to the gas supply
listed on the label.
Never use propane gas in a gas fireplace
designed for natural gas or natural gas in a gas fireplace
designed for use with propane gas.
The gas fireplace must be installed by an NFI Certified or
other qualified professional installer.
The installation,
including provisions for combustion and ventilation air, must
conform with local codes, or, in the absence of local codes,
with the latest edition of the National Fuel Gas Code, ANSI
Z223-1, and NFPA54.
Keep the fireplace area clear and free from combustible
materials, gasoline, and other flammable vapors and liquids.
The fireplace must have a gas supply line that has been
installed by a qualified technician in accordance with all local
codes. The gas supply line must be ½" minimum interior
diameter. If the gas line to the fireplace is longer than 5', a
larger diameter line may be necessary.

*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
pressure 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 pressure 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 fireplace 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.
