NEVER USE AN OPEN FLAME FOR LEAK TESTING

Operating Instructions

PILOT LIGHT:

1.Turn off the gas to the fireplace. If not recently done, remove the glass and let the unit air out for at least five (5) minutes to clear out any gas. Turn on gas to the heater. Leak test all joints with soapy water. NEVER USE AN 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. Hold the gas control knob in for thirty

(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 flame.

4.Leak test all gas joints again.

VENTURI ADJUSTMENT:

The venturi adjustment lever is centered above the control panel.

The venturi allows the amount of air coming into the fireplace to be adjusted in order to accommodate different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot flame is burning normally and none of the burner ports are plugged. Let the fireplace burn for roughly fifteen (15) minutes and then examine the flames.

The ideal flame will be blue at the base and light orange above (see Figure 42). The flames should be of medium height. If the flames look like this, no venturi adjustment is needed. If the flames are fairly short and mostly blue, the fireplace is getting too much air. Therefore, the air shutter should be closed (push in) slightly until the correct flames are achieved. Flames that are very orange, with tall dark stringy tips are not getting enough air. Open (pull out) the venturi until the flames clean up. If the venturi is opened, then closed all the way, and the correct flames 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.
