The pilot flow adjustment is set to maximum at the factory
and should not need to be adjusted. The pilot flame should
cover ⅜” to ½” (10 to 13mm) of the flame sensor (see Figure
17). However, should the need arise, turn the adjustment
screw to alter the pilot gas flow.

The air shutter plays a very important role in flame appearence and combustion quality. The shutter
adjusts how much air gets mixed with the gas before it ignites; adjustments can be made to accomodate
various climates and vent configurations.
Remove surround to access the air shutter. Find the lever underneath the firebox (see Figure 15). Moving
the lever inward (closed) will make the flame appear more yellow and tall; moving the lever outward
(open) will make the flames appear more blue and short.
Typically natural gas flames will require
the shutter to be more closed.
Typically LP flames will require the
shutter to be more open.
If you cannot attain a healthy flame by making
air shutter adjustments, you may have the
incorrect restrictor setting or venting problem.
If the flame is very flickery, fast moving, and
low then increase the restriction.
If the flame is very tall, lazy, and dirty then
decrease the restriction.
More details can be found in the venting section
of this manual.
Caution: Wear heat resistent gloves when
making adjustments to the air shutter.
Perform adjustments after 15 minutes.
