WARNING: The glass door must be securely in place before operating the fireplace. Do not operate the fireplace if glass is missing or broken.

BURNER FLAME ADJUSTMENT

The air shutter is located at the underside of the main burner (There are two (2) air shutters on the Propane gas versions). All have been factory preset to the proper air-to gas ratio which results in an even, clean burning flame across the burner (See Figure 31).

If readjustment is necessary, you can restore the proper air to gas ratio by loosening the air shutter screw and rotating the air shutter until the proper flame setting is achieved. (The air shutter’s normal setting is “fully opened”). Do not forget to retighten the air shutter screws (refer to figure 32).
