OPTIONAL THERMOSTAT
A optional thermostat may help you maintain a constant house 
temperature automatically. A millivolt thermostat is required. A 
fi xed wall mount or hand held model can be used. The control 
panel can be set up two ways to operate your stove in thermostat 
mode.
THERMOSTAT INSTALLATION
•  A MILLIVOLT NON-PROGRAMMABLE THERMOSTAT IS REQUIRED.
•  Unplug stove from power outlet.
•  Remove control board from stove.
•  The two thermostat wires connect to the terminal block on the 
lower left side of the back of the control board.
•  Insert the wires in the terminal side and tighten the two screws.
MODES
TO SWITCH BETWEEN ANY OF THE THREE MODES THE 
STOVE MUST BE SHUT OFF, THE NEW MODE SELECTED, 
AND THE STOVE RESTARTED.
MANUAL MODE
•  USE THIS MODE EXCLUSIVELY IF YOU DO NOT CON-
NECT AN OPTIONAL THERMOSTAT.
•  In this mode the stove will operate only from the control panel 
as detailed in the “OPERATION” section of this owner’s manu-
al.
HIGH/LOW THERMOSTAT MODE
•  USE THIS MODE ONLY IF YOU CONNECT A THERMOSTAT.
•  When engaged in this mode the stove will automatically switch 
between two settings. When warm enough, it will switch to the 
#1 or low setting. The room air blower will also slow to its low-
est speed.
•  The Heat Level Advance setting on the bar graph will stay 
where it was initially set. When the house cools below the ther-
mostat setting, the stove will switch to the feed rate of the heat 
level advance setting.
ON/OFF THERMOSTAT MODE 
(Ignitor life will be cut down in this mode)
•  USE THIS MODE ONLY IF YOU CONNECT A THERMOSTAT.
•  In this mode, when the home is warm enough the stove will 
shut off. The fans will continue to run until the stove cools.
•  When the home cools below the thermostat setting, the stove 
will automatically restart and run at the last feed rate setting.
NOTE: When in “high/low” or “on/off” thermostat mode –
•  Do not operate the stove higher than the #3 setting.
•  Set damper control rod approximately 1/4” to 1/2” out. This will 
vary depending on elevation and weather conditions. Observe 
stoves operation and adjust damper as necessary.
