OPERATING HEATER

FOR YOUR SAFETY READ

BEFORE LIGHTING

WARNING: If you do not fol- low these instructions exactly, a fire or explosion may result causing property damage, per- sonal 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 neighborʼs phone. Follow the gas supplierʼs instructions.

•If you cannot reach your gas supplier, 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, donʼt try to repair it, call a qualified service tech- nician 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 control which has been under water.

1.STOP! Read the safety information above.

2.Make sure equipment shutoff valve is fully open.

3.Turn pilot knob clockwise to the OFF position.

4.Wait five minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information above. If you donʼt smell gas, go to the next step.

5.Press in pilot knob and turn counterclock-

wise to the PILOT position. Keep pilot knob pressed in for five (5) seconds (see Figure 17).

6.With pilot knob pressed in, push in ignitor button. This will light pilot. The pilot is located at the bottom of plaque burners. If needed, keep pressing ignitor button until pilot lights.

Note: If pilot does not stay lit, refer to Troubleshooting, page 17. Also contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with a match. To light pilot with a match, see Manual Lighting Procedure, page 14.

7.Keep pilot knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release pilot knob.

•If pilot knob does not pop up when re- leased, contact a qualified service person or gas supplier for repairs.

Note: If pilot goes out, repeat steps 3 through 7.

8.With the auxiliary knob in the ON posi- tion, turn pilot knob counterclockwise to start the heater. The main burner should light.
