GAS CONNECTIONS
Before connecting the appliance to the gas supply line, double check that the appliance you hav e
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 connectio ns.
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. Up stream 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 scre w 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.
