DAMPER CONTROL
This fi replace is fi tted with a manually controlled
chimney damper. The chimney damper should
be closed when the fi replace is not in use to
prevent cold air from entering the home through
the chimney system.
The damper is controlled through the use of a
control lever located within the fi rebox opening
at the top center just behind the fi rebox lintel
(Figure 2). The control lever snaps into place
at the extreme range of motion, up and back in
the closed position. When pulled forward and
down, the damper is open.

Figure 2
1. The appliance fl ue damper must always
remain open when operating.
2. The grate in the fi rebox should be centered
on or over the bottom hearth so your fi re
can breath properly. Crumble and twist
plenty of newspapers UNDER the grate and
criss-cross some small dry kindling sticks
on top of the paper or on the bottom of the
grate.
3. Build a pyramid of three split logs (split will
start much faster). Arrange the uneven wood
to provide plenty of air space between.
4. When lighting your fi re, a little smoke may
escape – more likely if the chimney is cold.
To correct this, hold a lighted newspaper up
inside the fi rebox near the chimney open-
ing. This will turn around any downdraft
and clear the fl ue of cold air. As your log
re burns below, the updraft will improve
as the chimney heats up.
5. Now, light the paper at both sides of the
rebox.
6. Close the screens to prevent the escape of
sparks and embers.

GLASS DOOR OPERATING SAFETY
PRECAUTIONS AND INSTRUCTIONS
These fi replaces may be equipped with glass
doors. Refer to Pages 10 & 11 for a list of
the glass doors approved for use with these
replaces.
WARNING
If your fi replace is equipped with
glass doors, it should be oper-
ated with the doors fully open or
fully closed. If the doors are left
partially open, gas and fl ames
may be drawn out of the open-
ing, creating risks of both fi re
and smoke. Refer to Figure 4 for
proper operating conditions.
AVERTISSEMENT
Les portes du foyer doivent
demeurer totalement ouvertes
ou totalement fermées lorsque
le foyer fonctionne. Si elles sont
partiellement ouvertes, il y a
un risque d’avoir de la fumée à
l’intérieur de la pièce et de pro-
voquer un incendie. Le pare-étin-
celles optionnel doit être utilisé
lorsque le foyer fonctionne avec
les portes ouvertes. Référez-vous
aux Figure 4 pour des conditions
d’opérations appropriées.
7. For indoor installations, close the damper
only when your fi re is completely out and
ashes are cold. Keep closed when fi replace
is not in use to prevent unnecessary loss of
heated or cooled air.
COMBUSTION AIR INLET
This appliance requires the installation of an
air inlet for proper operation when installed
outdoors.
The fi replace draws air into the chimney and
rebox chambers through the air inlet to cool
the fi rebox during operation.
It is important to inspect the air inlet and free
it from any obstruction before operating the
replace (see Figure 3).
WARNING
Do not operate the fi replace out-
doors unless a complete air inlet
system has been installed.
AVERTISSEMENT
N’actionnez pas la cheminée
dehors à moins qu’un système
complet d’entrée d’air ait été
installé.
