FOR YOUR SAFETY: READ BEFORE LIGHTING
A. This heater is equipped with an ignition device which
automatically lights the pilot. Do not try to light the
pilot by hand.
B.
BEFORE OPERATING
smell all around the heater
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 heater.
-
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. Forced or attempted repair may result in a
fire or explosion.
D. Do not use this heater if any part has been under water.
Immediately call a qualified service technician to inspect
the heater and to replace any part of the control system
and any gas control which has been under water.
