Gas Controls/Control Compartment
Access
The gas controls can be found behind the control
compartment access door.
Removing Control Compartment Door
Open the panel by grasping the control
compartment door on both sides and gently
pulling the top away from the fireplace to
disengage the magnetic fasteners. The door is
hinged at the bottom. If greater access to the
control compartment is required, slide the door,
first to one side and then the other, so the tabs
clear both of the locating holes.
OPERATION AND CARE OF YOUR APPLIANCE
WARNING
Young children should be carefully supervised when they are in the
same room as the appliance. Toddlers, young children and others
may be susceptible to accidental contact burns. A physical barrier is
recommended if there are at risk individuals in the house. To restrict
access to a fireplace or stove, install an adjustable safety gate to keep
toddlers, young children and other at risk individuals out of the room
and away from hot surfaces.
AVERTISSEMENT
Les jeunes enfants devraient être surveillés étroitement lorsqu’ils se trou-
vent dans la même pièce que l’appareil. Les tout petits, les jeunes enfants
ou les adultes peuvent subir des brûlures s’ils viennent en contact avec
la surface chaude. Il est recommandé d’installer une barrière physique
si des personnes à risques habitent la maison. Pour empêcher l’accès à
un foyer ou à un poêle, installez une barrière de sécurité; cette mesure
empêchera les tout petits, les jeunes enfants et toute autre personne à
risque d’avoir accès à la pièce et aux surfaces chaudes.

On millivolt systems, the piezo igniter, HI/LO
flame adjustment knob, and pilot and main
gas OFF/ON control knob are located below
the glass panel enclosure. The gas valve for
electronic systems is also located below the
glass enclosure panel (see
Figure 1
)
.
Reinstalling Control Compartment Door
If necessary, reinstall the door by inserting
the tabs on each side of the door into the
corresponding holes in the control compartment
opening, one side first then the other. Swing the
door gently up and fasten it by pushing it in until
the magnetic latches catch and lock it in place.
The standard controls for appliance operation
are located behind the panel below the appliance
front glass enclosure panel (
Figure 1
). Optional
control switches are also available (see
Page
17
- Remote Wall Switch, Remote Control or
Unit Mounted Rocker Switch).
Operation of millivolt and electronic gas con-
trol systems are different. Before lighting and
operating your appliance determine if you have
a millivolt or electronic appliance. Familiarize
yourself with the gas control valve that your
appliance uses. Refer to
Figure 1
for access to
the gas control valve.
Millivolt Appliances
- Appliances with
Millivolt systems will be fitted with the gas
control valve shown in
Figure 3.
Electronic Appliances
- Appliances with
electronic systems will be fitted with the
electronic valve shown in
Figure 4.
Millivolt Appliances -
To light millivolt ap-
pliances refer to
Figure 1
. Detailed lighting
instructions are found on
Page 20
.
Millivolt
appliance lighting instructions may also be
found on the pull out lighting instruction labels
attached to the gas control valve
.
Once the pilot is lit, the main burner may be
turned ON and OFF using a wall switch, remote
control or optional on unit rocker switch (FRS).
To operate: Toggle the switch between its ON
and OFF positions.
If your millivolt appliance is equipped with an
optional remote switch kit (wall switch, remote
control, or rocker switch) and the pilot is lit, the
appliance main burner may be turned on and
off using the optional switch.
NOTE:
To prevent excessive resistance in
burner circuit (which can cause burner opera-
tion problems), only one burner control switch
should be wired to valve.
