For Automatic Ignition Models

Please read carefully and understand the following safety information before operating the boiler.

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 boiler is equipped with an ignition device which automatically lights the pilot. Do not try to light the pilot by hand; or this boiler may not have a pilot and is equipped with a hot surface ignition device which automatically lights the burners. Do not try to light the burners by hand.

B.BEFORE OPERATING smell all around the boiler area for gas. Be sure to smell next to the floor because some gases are 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 electrical switch.

• Do not use any phone in your building.

• Immediately call your gas supplier from a neigh- bor'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, move or turn the gas control knob or lever. Never use tools. If the knob or lever will not push in, move or turn by hand don't try to repair it, call a qualified service
