2. Start the pilot by pressing the gas control knob and turning it to PILOT.
While holding the gas control knob in, press the piezo ignitor several
times until the pilot light starts. Hold the gas control knob in for 30
seconds. Check that the pilot has fully engulfed the thermocouple
assembly (see Figure 3).
3. Start the main burner by turning the gas control knob to ON and then
turn the rocker switch to ON. Check that all burner ports have ame.
4. Leak test all gas joints again.

Operating Instructions
PiLot Light:
1. Turn off the gas to the replace. If not recently done, remove the glass and let the unit air out
for at least ve (5) minutes to clear out any gas. Turn on gas to the heater. Leak test all joints
with soapy water. NEVER USE OPEN FLAME FOR LEAK TESTING.
aiR shutteR:
The air shutter is controlled with the primary air adjustment rod located behind the gas valve shown in
Figure 4.
The air shutter allows the amount of air coming into the replace to be adjusted in order to accommodate
different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot
ame is burning normally and none of the burner ports are plugged. Let the replace burn for roughly
fteen (15) minutes and then examine the ames, compare the ames to Figure 61.

The ideal ame will be blue at the base and light
orange above. The ames should be of medium
height. If the ames look like this, no venturi
adjustment is needed. If the ames are fairly
short and mostly blue, the replace is getting
too much air. Therefore, the air shutter should
be closed slightly until the correct ames are
achieved. Flames that are very orange, with tall,
dark, stringy tips, are not getting enough air.
Open the venturi until the ames clean up. If the
venturi is opened, or closed all the way, and the
correct ames cannot be attained, turn off the
gas and contact the dealer.
Warning: Incorrect venturi adjustment may lead
to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the
venturi adjustment.
