THERMOSTAT INSTALLATION:
NOTE: Always Disconnect Power Before Performing The Thermostat Installation
.
A 24 volt wall thermostat and 20 feet of 18-gage thermostat wire is included in your stoves accessory package. It is rec-
ommended that the thermostat and thermostat wire be installed by an authorized Lennox Hearth Products dealer.
Installation Steps:
1. Unplug stove power cord from the wall outlet.
2. Locate the thermostat terminal block (see illustrations below).
3. Loosen the two terminal screws on the terminal block and remove the jumper.
4. Connect the two wires from your thermostat to the terminals (one per terminal). Ensure that the purple wires from the
harness remain connected to the terminal block and tighten the terminal screws. Make sure the wires are firmly con-
nected to the thermostat.
5. Plug in the stove and you are ready to operate with your thermostat!
IMPORTANT: IF THE WALL THERMOSTAT PROVIDED IS NOT USED, THE JUMPER IS REQUIRED FOR THE
STOVE TO OPERATE.
