OPERATING FIREPLACE

MILLIVOLT MODELS

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 

INSTRUCTIONS

NOTICE: During initial operation 

of new heater, burning logs will 

give off a paper-burning smell. 

Orange flame will also be pres-

ent. Open window to vent smell. 

This will only last a few hours.

1.  STOP!  Read  the  safety  information, 

column 1.

2.  Turn wall switch to the OFF position.

3.  Turn off all electric power to the appliance.

4.  Open control access panel.

5.  Push in gas  control knob and turn clock-

wise 

  to  the  OFF  position  (see 

Figure 23). 

Note:

 It is recommended that 

you maintain the gas control knob in the 

full OFF position during lengthy periods 

of seasonal non usage.

6.  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.

7.  Turn control knob counterclockwise 

 

to the PILOT position.

8.  Push in control knob all the way and hold 

in. Immediately light the pilot by pressing 

the red ignitor button until a flame ap-

pears. Continue to hold the control knob 

in for about (1) minute after the pilot is lit. 

Release knob and it will pop back up. Pilot 

should remain lit. If it goes out, repeat steps 

5 through 8.

•  If knob does not pop up when released, 

stop and immediately call your service 

technician or gas supplier.

•  If the pilot will not stay lit after sev-

eral tries, turn the gas control knob to 

“OFF” and call your service technician 

or gas supplier.

9.  Turn gas control knob counterclockwise 

 to “ON”. Knob can be turned to 

“ON” only if the control knob is popped out.

10.  Replace control access panel.

11.  Turn on all electric power to the appliance.
