GAS CONNECTIONS
Before connecting the appliance to the gas supply line, double check that the appliance you
have purchased is designed for the gas type you are using. The gas type markings are
located on the certification label and also on the appliance’s gas valve.
Provide adequate clearance for proper installation and checking of the gas connections.
Have your gas supplier or a qualified gas fitter run a gas supply line into the gas fireplace.
The line must be properly sized and fitted according to the installation codes. Upstream of
the appliance supply connection, the fitter shall provide an easily accessible manual shut-
off valve.
CAUTION: The appliance and its individual shutoff valve must be disconnected from
the gas supply piping system during any pressure testing of that system at
test pressures in excess of 1/2 psig (3.5 kPa). The appliance must be
isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig (3.5 kPa). Failure to do so will
damage the appliance’s gas valve. Such damage is not covered by the
manufacturer’s warranty.
Check for proper gas supply pressure by loosening the set screw on the supply pressure tap
(marked IN) on the gas valve with a small flat tip screw driver and placing a test gauge on
the tap.
The minimum permissible gas supply pressure is 4.5 in. w.c. (1.12 kPa) for natural gas and
11.0 in. w.c. (2.74 kPa) for propane. Maximum gas supply pressure should never exceed
14.0 in. w.c. (3.48 kPa) or 1/2 psi. for both natural gas and propane.
BE SURE TO TIGHTEN THE PRESSURE TAP SET SCREW AFTER CHECKING
THE PRESSURE. CHECK ALL GAS CONNECTIONS FOR GAS LEAKS.
