Installation
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.
Adequate clearance for proper installation and checking of the gas connections must be provided. All gas connections must
be checked for gas leaks.
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 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. (2.73 kPa) and a maximum of 14” W.C. (3.5 kPa). The orifice is a #51
DMS (1.70 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 31,000 BTU/hr (9.0 kW)
4500 ft. (1372 M) and above. 31,000 BTU/hr (9.0 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.
INSTALLERS NOTE
THE INPUT RATING SHOULD BE CHECKED ON INITIAL START-UP OF THIS APPLIANCE.
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 (3600 x Calorific Value) divided by the time (in seconds) it takes for (1)
rotation of the 1 cubic foot dial on the meter.
Adjust the manifold pressure so that the unit does not operate above the rated input.
