A. This appliance has a pilot that must be lighted

by hand.  When lighting the pilot, follow these
instructions exactly.

B. BEFORE LIGHTING smell all around the appli-

ance 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 appliance.

Do not touch any electrical switch; do not use
any phone in your building.

Immediately call you gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.

If you can not 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.  It knob will not
push in or turn by hand, don’t try to repair it; call
a qualified service technician or gas supplier.
Force or attempted repair may result in a fire or
explosion.

D. Do not use this appliance if any part has been

underwater.  Immediately call a qualified service
technician to inspect the appliance and to
replace any part of the control system which
has been underwater.

LIGHTING INSTRUCTIONS

1.

STOP!

 Read the all safety information included

with and on the side of heater.

2.

Check that gas supply to heater is on.

3.

Push in gas control knob and slightly turn
clockwise to the OFF position (see figure 16).

Note:

 Knob cannot be turned from PILOT to OFF

unless knob is pushed in slightly. Do not force.

4.

Wait five (5) minutes.  Then smell for gas,
including near the floor.  If you smell gas, 

STOP!

Follow “B” in the safety information above. If you
do not smell gas, go to the next step.

5.

Push in gas control know slightly and turn
counterclockwise to PILOT/IGN and depress for
five (5) seconds.

 The first time that the heater is operated after

connecting the gas supply, the control knob should
be depressed for about 30 seconds.  This will allow
air to bleed from the gas system.

Push in control knob and rotate control knob
back to OFF position then rotate counterclock-
wise to PILOT/IGN position.  This will light pilot.
If needed gently keep rotating control knob back
and forth while depressed until pilot lights.

seconds after lighting pilot.  If pilot goes out,
repeat steps 4, 5, 6 and 7.

If pilot does not stay lit, refer to Troubleshooting,
pages 14 & 15.  Also, contact a qualified service
person or gas supplier for repairs.

If control knob does not pop up when released,
contact a qualified service person or gas
supplier for repairs.
