System Check
1.PURGE 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 stove’s rating plate. All subsequent lightings of the stove will not require such purging of the gas line.
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.
The pilot flame should engulf the top 3/8” of the thermopile (for millivolt generation) and the top 1/8” of the thermocouple. The pilot flame should project out of the pilot hood 1” at all three port. See Figure 24.

3.BURNER ADJUSTMENT: The GF3 DVII Allagash gas stove is equipped with a variable gas control valve. This valve provides easy adjustment of the flame height appearance and heat output. To adjust the flame between the HI and LOW setting, rotate the HI/ LOW knob, located in the center of the valve face. Flame height will adjust approximately 1.0” to 1.5” between the HI and LOW settings. See Figure 25.
NO SMOKE OR SOOT SHOULD BE PRESENT. CHECK LOG PLACEMENT IF ANY SOOT OR SMOKE IS DETECTED. IF SOOT OR SMOKE PERSIST, THE AIR SHUTTER MAY NEED TO BE ADJUSTED. See Air Shutter/Flame Appearance section of this manual for proper air shutter settings and adjustments. Note: The more offsets there are in the vent system, the greater the need for an air shutter adjustment.
