for natural gas and 1/2" minimum open for L.P. gas.
NOTE: For altitudes above 5,000’
, some variations may be required.
Be sure burner and logs are properly installed. After log set has been properly installed, adjustments to the air shutter shall be
made for final flame appearance. These small shutter adjustments can be made by the following procedure:

The burner air shutter adjustment cable is located on the right side of the fireplace. It is located at the bottom of the right-side
