OPERATING INSTRUCTIONS

FOR YOUR SAFETY READ BEFORE LIGHTING

If you do not follow these instruction exactly, a ﬁre or explosion may result causing property damage, personal injury or loss of life.

A.This appliance is equipped with a piezo ignition device which lights the pilot. If piezo is not working properly see Match Lighting Instructions, page 30.

B.BEFORE OPERATING 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 attempt 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 of it 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 that has been under water.
