Air Shutter Adjustment
1.Open the Lower Grill panel and locate the Air Shutter adjustment stem extending down from the firebox floor. See fig. 27.
2.Loosen the wingnut and pull the stem to the forward to open the air inlet and allow more air into the burner. Make adjustments in 1/8” (3 mm) increments.
Allow the fireplace to burn 15
4.If the flame appears weak, slow, or sooty, move the shutter back further and repeat the process until the flame is as desired. Retighten the wingnut.
Air Inlet Settings
Natural Gas - 1/4” open
Propane - 1/2” open
IMPORTANT: Run the fireplace for a minimum of 15 to 20 minutes to produce an accurate representation of the flame appearance. This
Variable Vent Restriction
You may find it necessary to restrict the vent to some degree to accommodate the characteristics of your individual installation. Generally, the taller the vent height, the more likely may be the need to restrict air intake to achieve the desired flame picture and/or heat output. Vent restriction is accomplished by a single panel that slides over the combustion air intake port located at the right rear of the firebox. The Air Intake Restrictor Plate is set in the fully open position at the factory. The panel can be adjusted while the burner is operating.
1.Locate the adjustment stem (see fig. 28) and loosen the wingnut.
2.With the burner operating, move the stem to the right in 1/4” increments until the desired flame picture or heat output is achieved. After each adjustment, wait a few minutes to allow the burner to settle in to the new air flow before making further adjustment.
3.When the desired result is achieved, retighten the wingnut.
