THERMOSTAT OPERATION

Frequent operation of your heater will enable you to determine your own comfort levels.

2.With thermostat control knob pressed in, strike match. Hold match to pilot until pilot lights.

3.Keep thermostat control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.
