Once the Champlain has been set in place,
connected and assembled as described in the
Clearances
To
Combustibles,
Components
&
Configurations,
Connections,
And
Connections sections of this manual, the unit
is almost ready to be lit for the first time.
The manufacturer tests each unit prior to
shipment, so ignition should take place
without failure. However, a number of small
adjustments
may
compensate for variations in gas pressure,
altitude, and other factors particular to each
installation.

The gas control valve is equipped with a
variable output control. This control varies
the rate of heat produced by the unit by
varying the gas pressure to the main burner
tube. A combination of heat output and the
thermostat setting affect the length of the
burn cycle. If your stove turns on and off too
often, try, first, reducing the burn cycle by
turning the HI/LOW knob, on the control
valve, to a lower setting. Using the variable
output control, the heat output of the unit
can be reduced for mild fall and spring
months, or maximized for the colder winter
months. This adjustment can be made, by
the homeowner, as necessary by turning the
variable output control knob to "HI", "LO"
or any setting in between.

HUTTER
The air shutter is used to regulate the air-to-
gas combustion mixture, which in turn
influences the size and color of the flames.
The air shutter has been positioned in the
general location needed for the type of gas
being used, however, if the unit is not
burning as well as it should, then the air
shutter may need adjusting. The air shutter
may need adjustment once the unit has been
installed to compensate for variations in

position, altitude, gas type conversions, and
other variables.
To determine if the air shutter needs
adjustment, it is necessary to view the flame
pattern with the variable output control knob
at its highest setting. Allow the unit to
operate for 10 minutes to allow the entire
unit to reach temperature and for the flame
pattern to stabilize. Generally, the more air
(open shutter) in the mixture, the bluer the
flame. Less air (closed shutter) results in a
more yellow flame, but too little air will
result
in
incomplete
efficiency and a dirty burn. There are two
simple guidelines to aid in determining the
correct flame pattern:
1. if the flame at the base of the logs is
completely blue, the air shutter may
be open too far;
2. if the flame is dirty or licks the top of
the stove, the air shutter may be
closed too far.
Some
conditions
through
air
adjustment must be made to the gas supply
pressure or by changing the restriction plate
location. Qualified service personnel must
preform
supply
pressure adjustments and restrictor plate
adjustments. Do not attempt to complete any
part of the installation or adjustment of this
unit unless technically qualified to do so.
