FOR YOUR SAFETY

READ BEFORE

LIGHTING

WARNING: If you do not fol- low these instructions exactly, a fire or explosion may result caus- ing property damage, personal injury or loss of life.

A.This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly.

B.BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS

•Do not try to light any appliance.

•Do not touch any electric switch; do not use any phone in your building.

•Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

•If you cannot reach your gas sup- plier, call the fire department.

C.Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call a qualified service technician or gas supplier. Force or attempted repair may result in a fire or explosion.

D.Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas con- trol which has been under water.

2.Make sure equipment shutoff valve is fully open.

3.Push in control knob slightly and turn

clockwise to the OFF position (see Figure 19). Be sure that the tem- perature setting knob is set at the line between level 1 and level 7.

terclockwise to PILOT po- sition. Press in control knob for five(5) seconds.

Note: You may be running this heater for the first time after hook- ing up to gas supply. If so, you may need to press in control knob for 30 seconds. This will allow air to bleed from the gas system.

6.Release downward pressure on con-

trol knob and turn clockwise to OFF position.

7.Press in control knob and turn coun-

terclockwise past IGN to PILOT (see Figure 19). This will cause the piezo ignitor to spark and light the pilot gas. Keep control knob depressed for 10 seconds before re- leasing. If needed, repeat steps 5 through 7 until pilot lights.

THERMOSTAT

CONTROL

OPERATION

The thermostatic control used on this model differs from standard thermo- stats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room tem- perature. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any comfort level between 1 and 7.

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