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.
Adequate clearance for proper installation and checking of the gas connections must be provided. All
gas connections must be checked for gas leaks.
GAS CONNECTIONS
Have your gas supplier or a qualified gas fitter run a gas supply line into the fireplace. The line must
be properly sized and fitted according to the installation codes. Immediately upstream of the supply
connection, the fitter shall provide an accessible manual shut-off valve. When connecting the supply
line to the gas valve, the installer shall brace the gas valve to ensure that the gas valve is not moved
from its bracket. If the valve is not braced when the supply line is connected, the valve may be
moved and cause a “break” in the main burner supply line. Such damage is not covered by the
manufacturer’s warranty.
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.
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 4.5” W.C. (1.2 kPa) and a maximum of 14”
W.C. (3.5 kPa). The orifice is a #33 DMS (2.87) drill size.
ELEVATION INPUT RATING
0-4500 ft (0-1372 M) 33,000 BTU/hr (9.6 kW)
4500 ft (1372 M) and above.
33,000 BTU/hr (9.6 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 11” W.C. (2.8 kPa) and a maximum of 14”
W.C. (3.5 kPa). The orifice is a #51 DMS (1.73 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 31,000 BTU/hr (9.02 kW)
4500 ft. (1372 M) and above. 31,000 BTU/hr (9.02 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.
NOTE: THE INPUT RATING SHOULD ALWAYS BE CHECKED WHEN FIRST RUNNING THIS
APPLIANCE. To do this, reduce the background flow rate, time the meter, light the fireplace and
take another reading after 15 minutes of operation. Check with your gas supplier for the gas BTU
content at your elevation. Input is the rate of flow multiplied by the heating value of the gas (cubic
feet/hour x BTU per cubic feet). Adjust the manifold pressure so that the unit does not operate above
the rated input.
