WARNING: If you do not follow these instructions exactly,
a fire or explosion may result causing property damage, personal injury or loss of life.
A.This appliance has a pilot which must be lighted by hand. When lighting the pi- lot, 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 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, don’t try to repair it, call a qualified service technician. 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 start- ing in column 1.
2.Make sure equipment shutoff valve is fully open.
3.Turn off any electric power to the appli- ance if service is to be performed.
4.Turn control knob clockwise 
to the OFF position.
5.Wait five (5) 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 starting in column 1. If you don’t smell gas, go to the next step.
6.Thermostat Models: Turn control knob
counterclockwise 
to the PILOT position. Press in control knob for five (5) seconds.
Manual Models: Press in and turn control
knob counterclockwise 
to the PI- LOT position. Keep control knob pressed in for five (5) seconds.
7.With control knob pressed in, push down and release ignitor button. This will light pilot. The pilot is attached to the front of burner.
Note: You may be running this heater for the first time after hooking up to gas sup- ply. If so, the control knob may need to be pressed in for 30 seconds or more. This will allow air to bleed from the gas system.
If needed, keep pressing ignitor button until pilot lights. If ignitor does not light pilot, refer to Troubleshooting, page 18 or contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match. See Manual Lighting Procedure, page 14.
