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.

Millivolt Appliances -
To light millivolt appliances refer to Figure
1. Detailed lighting instructions are found on
Pages 22 and 23. 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, unit-mounted rocker switch, 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 or remote
control) and the pilot is lit, the appliance main
burner may be turned on and off using the
optional switch. When using an optional remote
switch, turn off the standard OFF/ON switch.
Note: To prevent excessive resistance in burner
circuit (which can cause burner operation
problems), only one burner control switch
should be wired to valve.
Gas Controls/Control Compartment Access
The standard controls for appliance operation are located behind the hinged drop-down panel
below the appliance front glass enclosure panel (see Figure 1). Optional control switches are also
available (see Page 18 - Remote Wall Switch or Remote Control).
To open the control compartment access panel, actuate the spring-loaded magnetic catches securing the panel. First, depress the outer top right corner of the panel until the catch "pops" the door
free. Then, gently pull the door forward until the left top corner "pops" free, allowing the panel to
swing out and down to open.
To ease door closure, depress the catches to place them in their retracted position, then close
the door.

Variable Flame Height Adjustment
(Millivolt Appliances only)
All Millivolt appliances are equipped with a
variable gas control valve. Flame height for
these models may be adjusted through a range
between fixed low and high settings while the
appliance is in operation. Adjust the flame
height as desired after lighting the appliance
by rotating the variable adjustment control
knob (HI/LO) located on the front of the valve
(refer to Figure 2).
VENT OPERATION TEST
A vent operation test is required as part of the
installation to verify that proper venting conditions exist and should be done periodically to
ensure nothing has changed that would affect
proper venting of the appliance.
Procedure:
1. ENSURE APPLIANCE IS OFF (PILOT ONLY)
AND COOL.
2. Open both latches on one of the glass
enclosure doors and slightly prop it open at
the bottom (approx. 1/4” gap). See Figure
6 on Page 12.
3. Turn on all the exhaust fans in the dwelling
(and any other appliances which remove
air from the dwelling, such as a furnace or
clothes dryer, etc.).
4. Ensure that all the doors and windows in
the room where the fireplace is located are
closed.
5. Light the appliance (see Lighting Instruc-
tions, Pages 22 to 25). Adjust flame height to
highest setting and operate for approximately
5-10 minutes. Do not leave appliance unattended.
6. Take a smoke producing device and move it
along the bottom edge of the glass door (where
it is cracked open). If smoke is drawn into the
firebox, the vent operation is adequate.
IF THE SMOKE IS NOT DRAWN INTO
THE FIREBOX, TURN THE APPLIANCE
OFF AND CALL A QUALIFIED SERVICE
TECHNICIAN.
SPILL SWITCH OPERATION
Manual-Reset (safety limit) Spill Switch
This appliance is equipped with a (safety limit)
spill switch that is designed to "trip" and discon-
nect the burner circuit if flue spillage occurs
(because of improper venting of combustion
products or vent blockage). If, during appliance
operation, the burner flame goes out (independently of the burner OFF/ON wall switch), it may
be due to the operation of this (safety limit) spill
switch. If this switch "trips" it will need to be
manually reset by pressing the reset button on
switch (see Figure 4).
Procedure to Reset (safety limit) Spill Switch
ALLOW APPLIANCE TO COOL COMPLETELY
BEFORE ACCESSING AND RESETTING
To access the spill switch:
1. Pull off the top louvered panel.
2. Locate and press the red reset button on
the switch (it will click & lock in).
The appliance should then relight and remain
lit. If this does not occur, turn off the appliance
and call a qualified service technician.

Outside Combustion Air Controls
Many appliances are equipped, when installed,
with an outside (make-up air) vent system
that is designed to provide the appliance with
outside make-up air for combustion when in
operation.
The outside air control lever for the outside
air system is standard on all appliances but
should not be operated if the complete system
is not installed. Refer to Figure 5. When the
complete outside air vent system is installed,
the installer will remove the securing screw
from the combustion air control lever located
on the right side of the fireplace opening.
If the securing screw has not been removed
and you have reason to believe that you have
a complete outside air system, contact your
distributor to have your appliance inspected for
the presence of the complete system. DO NOT
assume that you have this system in place.
WARNING
Do not operate the shutoff lever
unless a complete outside combustion air system has been
installed with your appliance.
To open the outside air shutter, open the bottom
control access panel, and pull the outside air
control lever all the way out. The outside air
shutter should be fully open when the fireplace
is in use and completely closed when the fireplace is not being used. Closing it when not in
use will prevent outside cold air from entering
the dwelling.
The hand operated outside air control lever is
located on the right side of the fireplace opening. See Figure 5.
To open the outside air , open the bottom control access panel, reach into the gap between
the firebox bottom and pull the outside air
control lever all the way out.
The outside air shutter should be fully open when
the fireplace is in use and completely closed
when the fireplace is not being used. Closing
it when not in use will prevent outside cold air
from entering the dwelling.
Operate the actuator through several cycles
including the closed position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the closed position.
