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.
The gas inlet is located at the bottom right rear of the stove.
The inlet tting is a 1/2" female are exible 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 rst 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 efcient 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, ame color, or cause pilot outage.

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