Operation
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 electrical 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.

indicator lights to aid you in the operation of the
