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. Adjustments can be made to accommodate various
climates and vent configurations.
To gain access to the air shutter remove the safety screen and intake shield. There is a lever underneath
the firebox near the gas valve as shown in Figure 3. Moving the lever to the right will close off the air mixing
with the gas and will make the flame appear more yellow and tall. Moving the lever to the left will open up
the shutter allowing more air to be mixed with the incoming gas; this will make the flames appear more blue
and short.

Proflame 2 is a modular remote control system that directs the functions of the C34I. The Proflame 2
TMFSLA is configured to control the on/off main burner operation, its flame levels and provides on/off
and thermostatic control of the appliance. The system also controls the optional fan speed through six
(6) levels and can control the operation of the option light kit.
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 the proper flame by
making air shutter adjustments then you
may have the incorrect exhaust restrictor.
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 resistant gloves
when making adjustments to the air
shutter. Perform adjustments after 15
minutes�
