ADJUSTING YOUR AIR SHUTTER TO PREVENT SOOTING
The correct fuel-air mixture in your Flare Fireplace produces yellow flame tips, with blue base and offers
minimal soot buildup. The Fuel-air mixture is set by the factory, but may need adjustment by fireplace
installer, depending on site conditions.
1.
Identifying and locating the air shutter on your Flare Fireplace.
EX 1:
AIR SHUTTER ON INSIDE OF FIREPLACE ON THE BURNER
EX 2:
AIR SHUTTER ADJUSTMENT UNDER YOUR FIREPLACE
●
Example 1:
If the fireplace has been completely installed, and no access can be had to the underside of the
fireplace, the adjustment can be done from inside the fireplace, on the burner. Each burner (
up to three
burners
,
on units 60” and above
) has a
+
and
–
sign located on it. In between that
+
and
–
sign is a Philips
head screw that can be turned to either increase or decrease the air to gas mixture.
See Ex. 1 above for visual.
●
Example 2:
The second option allows you to adjust your Flare Fireplaces air shutter by accessing it from
directly underneath the fireplace.
See Ex. 2 above for visual

Adjust the Air shutter if the Air to Fuel mixture is not correct:
●
Flame is Yellow or orange producing soot (low air leading to a rich flame) - Introduce more air by
turning clockwise.
●
Flame is very blue (too much air) - Reduce the air by turning counterclockwise.
Common reason air shutter adjustment may be needed:
●
LP conversion has been done.
●
High above sea level installation. High elevation with low oxygen in the air.
●
Soot buildup on the glass or termination cap
In all cases, it is recommended to verify inlet pressure to match recommended values, in
addition to setting the air shutter on the burner.
