OPERATION

FOR YOUR SAFETY READ BEFORE OPERATING

￿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 pool heater does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand.

B.BEFORE OPERATING, smell around the pool heater area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle to 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 turn the gas control lever. Never use tools. If the lever will not 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 pool heater if any part has been under water. Immediately call a qualified service technician to replace the pool heater. The possible damage to a flooded pool heater can be extensive and present numerous safety hazards. Any appliance that has been under water must be replaced.
