INSTALLATION

Burn Only the Fuel for which the Heater is Equipped

The Serenity III Direct Vent will burn either natural gas or propane, but requires a change over kit for propane. The label on the burner system mod- ule indicates the fuel for which it is equipped. A sec- ond label, (on the valve) also indicates the fuel type.

Making The Connection

The gas inlet is located on the bottom right side of the fireplace. The inlet fitting is a 3/8" female flare flexible pipe.

A separate gas shut-off valve and a 1/8" N.P.T. plugged tapping should be installed immediately up- stream of the connection to the appliance.

The Serenity III Direct Vent Gas Heater must be disconnected from the gas supply piping during any pressure testing of that system at pressures in excess of 1/2 psig (3.5 kPa).

The Serenity III gas control valve must be in the OFF position during any pressure testing of the gas supply system at pressures equal to or less than 1/2 psig (3.5 kPa).

WARNING: To avoid pipe compounds from entering into the gas train, apply compounds only to male pipe threads and do not apply compound to the first two threads.

CAUTION: TEST ALL JOINTS FOR LEAKS BEFORE OPERATING.

Gas Pressure Requirements:

Correct gas pressure and the use of a properly sized gas supply line are essential for the safe and efficient performance of this appliance. Make sure that the plumber or gas supplier checks the gas sup- ply line and gas pressure at installation.

NOTE: Improper gas pressure can affect heater performance, flame color, or cause pilot outage.

Natural Gas:

Maximum inlet pressure 7.0" w.c. (1.74 kPa) Minimum inlet pressure 5.0" w.c. (1.25 kPa) Gas manifold pressure 3.5" w.c. (0.87 kPa)

LPG Gas:

Maximum inlet pressure 13" w.c. (3.24 kPa) Minimum inlet pressure 11" w.c. (2.74 kPa) Gas manifold pressure 10" w.c. (2.49 kPa)

DO NOT USE THIS HEATER IF ANY PART HAS BEEN UNDER WATER OR EXPOSED TO MOISTURE CORROSION. IMMEDIATELY CALL A QUALlFlED SERVICE TECHNICIAN TO INSPECT THE HEATER AND REPLACE ANY PART OF THE CONTROL SYSTEM AND ANY GAS CONTROL WHICH HAS BEEN UNDER WATER.
