CONNECTING THE HEATER

TO A GAS SUPPLY

Burn Only the Fuel for which the Heater is Equipped The Clarity B-Vent will burn either natural gas or pro-

pane, but requires a dedicated burner system module for either fuel. The label on the burner system module indicates the fuel for which it is equipped. A second label, located near the rating plate, also indicates the fuel type.

PROPANE

Making The Connection

The gas inlet is located at the bottom right rear of the stove. The inlet fitting is a 1/2" female flare flexible pipe.

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

The Clarity B-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 Clarity gas control valve must be in the OFF position during any pressure testing of the gas supply system at pres- sures 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 the male pipe threads and only to the first two threads.

CAUTION: TESTALL 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 per- formance of this appliance. Make sure that the plumber or gas supplier checks the gas supply line and gas pressure at installation.

NOTE: Improper gas pressure can affect heater perfor- mance, 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 SYS- TEM AND ANY GAS CONTROL WHICH HAS BEEN UNDER WATER.

NOTE: NEVER USE PLASTIC PIPE. CHECK TO CONFIRM WHETHER YOUR LOCAL CODES ALLOW COPPER TUBING

OR GALVANIZED PIPE.

Whether or not you have installed a conversion kit, fill out the installer fuel label, on the stove, or the one that was included with the conversion kit, and affix it to the stove in the appropriate location.
