knob for five (5) seconds (see Figure 19). 

 

Note:

 You may be running this heater for 

the first time after hooking up to gas sup-

ply. If so, the control knob may need to be 

pressed in for 30 seconds or more. This will 

allow air to bleed from the gas system.

released, contact a qualified service person 

or gas supplier for repairs.

6.  With control knob pressed in, push down 

and release ignitor button. This will light

burner. The pilot can be seen through the 

glass panel. If needed, keep pressing ignitor 

button until pilot lights.

 

Note:

 If pilot does not stay lit, refer to 

Troubleshooting

, page 18. Also contact a 

qualified service person or gas supplier for 

repairs. Until repairs are made, light pilot 

with match. To light pilot with match, see 

Manual Lighting Procedure

, page 15.

7.  Keep control knob pressed in for 30 seconds 

after lighting pilot. After 30 seconds, release 

control knob.

• If control knob does not pop up when 

released, contact a qualified service person 

or gas supplier for repairs.

 

Note:

  If  pilot  goes  out,  repeat  steps  3 

through 7. This heater has a safety inter-

lock system. Wait one (1) minute before 

lighting pilot again.

OPERATING HEATER

FOR YOUR SAFETY  

READ BEFORE LIGHTING

 WARNING: If you do not fol-

low  these  instructions  exactly, 

a  fire  or  explosion  may  result 

causing property damage, per-

sonal injury or loss of life.

A.  This appliance has a pilot which must be 

lighted by hand. When lighting the pilot, 

follow these instructions exactly.

B.  BEFORE LIGHTING smell all around the 

appliance 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 electric switch; do not 

use any phone in your building.

• Immediately call your gas supplier from 

a  neighborʼs  phone.  Follow  the  gas 

supplierʼs 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, donʼt 

try to repair it, call a qualified service tech-

nician 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  under  water.  Immediately  call  a 

qualified service technician to inspect the 

appliance and to replace any part of the 

control system and any gas control which 

has been under water.

LIGHTING

above.

2.  Make  sure  equipment  shutoff  valve  is 

fully open.

3.  Turn control knob clockwise  

  to the 

OFF position.

4.  Wait five (5) minutes to clear out any gas. 

Then smell for gas, including near the floor. 

If you smell gas, STOP! Follow “B” in the 

safety information above. If you donʼt smell 

gas, go to the next step.
