4.Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Fol- low “B” in the safety information on page 10, column 3. If you don’t smell gas, go to the next step.

OPERATION

The control knob can be set to any heat level between HI and LO. When the room temperature exceeds the set temperature, the burner will cycle to pilot. The burner will cycle back on when room tempera- ture drops below the set temperature.

Note: The thermostat sensing bulb mea- sures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation loca- tion, room size, open air temperatures, etc.) Frequent use of your heater will let you determine your own comfort levels.
