FOR YOUR SAFETY, READ BEFORE OPERATING
_
A) This boiler 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 all around the boiler 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 boiler.
• 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 “shutoff” valve. Never use tools. If the handle 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 boiler if any part has been under water. Immediately call a qualified service technician
to inspect the
boiler and to replace any part of the
control system and any gas control which has been
under water.
