VENTURI ADJUSTMENT:
The venturi adjustment lever is centered above the control panel.
The venturi 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 minutes and then
examine the ames.
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 (push in) slightly until the correct ames are
achieved. Flames that are very orange, with tall
dark stringy tips are not getting enough air. Open
(pull out) the venturi until the ames clean up. If
the venturi is opened, then 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.
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.
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. Keep holding the gas control knob in for
30 seconds. Check that the pilot has fully engulfed the thermocouple assembly. See Figure 2.
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.
