ADJUST THE AIR SHUTTER
The venturi of the burner is equipped with an air shutter.
The opening of the venturi has been set at 1/4" for Natural
Gas and fully open for Propane installation at sea level.
The burner on Natural Gas models may be adjusted for
high altitude as follows:
•
To increase air mixture, open the shutter more. This
will reduce soot formation. Figure 27
