GAS CONNECTION

PRECAUTIONS

This appliance must be installed by a qualified gas installer and the installation must conform to the installation
codes. This appliance needs fresh air for safe operation and must be installed so there are provisions for
adequate combustion and ventilation air. Provide adequate clearance around air openings of the appliance. Never
obstruct front openings.
Provide adequate clearances for proper operation and servicing of the appliance.
This appliance must be properly connected to a venting system and must not be connected to a chimney flue
serving a separate solid fuel burning appliance.

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 and a 1/8 NPT plugged tapping accessible for connection to a
test gauge.

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 execss of 1/2 psig (3.5 kPa). The
appliance must be isolated from the gas supply piping systm 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” wc (1.1 kPa) and a maximum of 8” wc (2 kPa). The
orifice has a #41 DMS drill size.

ELEVATION INPUT RATING
0-4500 ft. (0-1372 m)

24,000 BTU/hr (7,000 watts)

4500 ft. (1372 m) + 24,000 BTU/hr (7,000 watts) less 4% per 1000 ft. (300 m)

or reduce manifold pressure by 0.25” wc (0.06 kPa) per 1000 ft. (300m)

Propane Pressure Settings:

The inlet supply or line pressure must be a minimum of 11” wc (2.8 kPa) and a maximum of 14” wc (3.5 kPa).
The orifice has a #54 DMS drill size.

ELEVATION INPUT RATING
0-4500 ft. (0-1372 m)

24,000 BTU/hr (7,000 watts)

4500 ft. (1372 m) + 24,000 BTU/hr (7,000 watts) less 4% per 1000 ft. (300m)

or reduce manifold pressure by 1” wc (0.25 kPa) per 1000 ft. (300m)

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, after fifteen (15) minutes of
operation, take another reading. 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). If the clocked
input rate is incorrect, check that the supply pressure and manifold pressures are close to those specified on
page 5. (Remember to close pressure tap test ports).

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.
