Use only a thermostat rated for 500 millivolts.
Check the table below for the appropriate gauge
thermostat wire to use for the length of lead required in
your installation.
1. Install the wall thermostat in the desired location and
run the wires to the stove location. Terminate these
leads with 1/4” female connectors.
2. Connect the thermostat wires to the valve. (Fig. 43)
This completes assembly of the Jefferson stove.
