OPERATION AND CARE OF YOUR APPLIANCE
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.
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.

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.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
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 appli-
ance front glass enclosure panel (Figure 1).
Optional control switches are also available
(see Page 18 - Remote Wall Switch, Remote
Control, Unit Mounted Rocker Switch or Wall
Thermostat).
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 Pages 21 and 22.

Millivolt appliance lighting instructions may
Latch
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, optional on unit rocker switch (FRS),
or wall thermostat. 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, rocker switch, or wall thermostat) 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 operation prob-
lems), only one burner control switch should
be wired to valve.
