Optima 32 - 1 9

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 up

stream of the supply connection, the fitter shall provide an accessible manual shut-off valve

and a 1/8 (3 mm) NPT plugged tapping accessible for connection to a test gauge. When

connecting the supply line to the gas valve, the installer shall brace the gas valve to ensure that

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” wc (1.1 kPa) and a maximum of 8”

wc (2 kPa). The orifice is a #35 DMS (2.79 mm) drill size.

ELEVATION INPUT RATING

0-4500 ft (0-1372 M) 34,000 BTU/hr (9.8 kW)

4500 ft (1372 M) and above. 34,000 BTU/hr (9.8 kW) less 4% per 1000 ft. (305 M)

Please contact your local utility or distributor for the appropriate orifice size you require.

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 is a #50 DMS (1.79 mm) drill size.

ELEVATION INPUT RATING

0-4500 ft. (0-1372 M) 34,000 BTU/hr (9.8 kW)

4500 ft. (1372 M) and above. 34,000 BTU/hr (9.8 kW) less 4% per 1000 ft. (305 M)

Please contact your local utility or 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.
