This increases or decreases the burner flame height. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room tem- perature drops below the set temperature. The control knob can be set to any heat level between HI and LO. Selecting the HI setting will cause the burner to remain fully on without modulating down in most cases.
NOTE: the thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not al- ways agree with room temperature
