The air shutter plays a very important role in flame appearance and combustion quality. The shutter adjusts
how much air gets mixed with the gas before it ignites. Start the fireplace and allow it to heat up for 15+
minutes before making adjustments.
The air shutter slider is located at the back of the unit (see Figure 4).
Adjustments:
Lean (more primary air): Pull slider outwards to make flame ap-
pear more blue and low.
Rich (less primary air): Push slider inward to make flame appear
more yellow and tall. Flame will continue to richen up during
operation creating a potential for gradual soot build-up.
Note:
If you cannot attain a healthy flame by making air shutter
adjustments, you may have the incorrect restrictor setting or a
venting problem.
Warning:
Incorrect shutter adjustment may lead to improper
combustion, which is a safety hazard. Contact the dealer if
there is any concern about the venturi adjustment.

*NOTE:
When the unit is turned on for the first time, it should be turned onto high, with the fan OFF, for
the first two to four hours. This will cure the paint, logs, gasket material, and other products used in the
manufacturing process. It is advised that a door or window be opened as the unit will start to smoke, which
can irritate some people. After the unit has gone through the first burn turn the unit OFF, including the pilot,
and let the unit get completely cold. Then remove the glass and clean it with a good gas fireplace glass
cleaner, available at your local Enviro dealer. See page 17 and page 18 for instructions on removing
fireplace door and glass.
