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 4).
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.
aiR shutteR (VentuRi):
The air shutter adjustment lever is underneath the rebox (see Figure 5).
The air shutter allows the amount of air mixing with the incoming gas 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 minutes and then examine the ames for impingement or soot build up.
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 (pushed it) 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.

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.
Remote contRoLs (oPtionaL):
This replace can use an optional remote control or an optional cordless wall thermostat. If either of
these are to be used to control the replace for the majority of the time, leave the ON/OFF switch (on the
control panel) in the remote/thermostat position. Consult the instructions included with the remote/wall
thermostat for operation guidelines.
