Jotul GZ 550 DV II Air Shutter Adjustment, Air Inlet Settings, Air Shutter adjustment location

Air Shutter Adjustment

1.Open the Lower Grill panel and locate the Air Shutter adjustment stem extending down from the right side of the firebox floor. See figs. 49.

2.Loosen the locknut and push the stem BACK (to the rear of the firebox) to open the air inlet increasing airflow into the burner. Push the stem FORWARD to decrease the air inlet. Make adjust- ments in 1/8” (3 mm) increments and allow time for flame pattern to respond to the new setting. Retighten the locknut when the desired flame pattern is established.

3.Reassemble the fireplace including glass assem- bly. Allow the fireplace to burn 15 -20 minutes on the HIGH setting, observing the flame continu- ously.

4.If the flame appears weak, slow, or sooty, repeat the process described above until the flame is as desired.
