FOR YOUR SAFETY READ BEFORE LIGHTING

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 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.

Note:

 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.
6. 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.

7. Keep control knob depressed in for ten (10)

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 12 & 13.  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.

When the pilot is lit, turn the control knob to “HI”

position to light heater.

After flame is established (see 

Burner Flame

Pattern

, Pages 10 and 11) on “HI”, adjust heat

output by turning control knob to desired position

(“LO” or “HI”). Do not operate heater between

locked positions.
