System Check

1.PURGING THE GAS LINE: When lighting the appliance for the first time it will take a few moments to clear the gas line of air. Once this purge is complete, the appliance will operate as described in the lighting instructions located on the fireplace’s rating plate and back cover of this manual.

2.PILOT FLAME: The pilot flame should be steady, not lifting or floating. The flame should be blue in color around the pilot hood, with traces of yellow toward the outer edges. It is imperative that the pilot flame engulf the top 3/8” of the thermopile (power generator) and the top 1/8” of the quick drop out thermocouple. The pilot flame should project out of the pilot hood 1” at all three ports. See Figure 48.

3.BURNER ADJUSTMENT: Your Jøtul GZ550 Acadia gas fireplace is equipped with a variable gas control valve. This valve provides easy adjust- ment of the flame height appearance and heat output. To adjust the flame between the HI and LO setting, rotate the HI/LO knob, located in the center of the valve face. Flame height will adjust approximately 1.0” to 1.5” between the HI and LO settings.

NO SMOKE OR SOOT SHOULD BE PRESENT. CHECK LOG PLACEMENT IF ANY SOOT OR SMOKE IS DE- TECTED. IF SOOT OR SMOKE PERSISTS, THE AIR SHUTTER MAY NEED TO BE ADJUSTED.

CAUTION:

DO NOT ATTEMPT TO ALTER THE FLAME APPEARANCE BY POSITIONING THE GAS VALVE IN ANY OTHER POSITION OTHER THAN THE FULL “ON” POSITION.

Flame Appearance / Air Shutter Adjustment

THE ACADIA GAS FIREPLACE IS SHIPPED FROM THE FACTORY EQUIPPED TO USE NATURAL GAS. IF THE BURNER HAS BEEN CONVERTED FOR USE WITH PROPANE, IT WILL BE NECESSARY TO ADJUST THE AIR SHUTTER ON THE BURNER TUBE TO ACHIEVE THE PROPER GAS TO AIR MIX. See Figure 26.

WARNING:

AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFES- SIONAL SERVICE TECHNICIAN.

The air shutter adjustment can also help achieve the desired flame appearance. Generally, flame appear- ance is a matter of individual preference, however a warm yellowish flame is most common. See fig. 49.

Closing the air shutter - will generate very long yellow flames resulting in soot. Sooting produces black deposits on the logs, on the inside walls of the appliance, and potentially on the exterior termination cap.

Sooting is caused by incomplete combustion in the flames and lack of combustion air entering the air shutter opening.

Opening the air shutter - will generate a flame that is blue and transparent, or an “anemic” flame. This flame is generally more efficient but not as pretty.
