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.

When lit for the first time, this appliance will
emit a slight odor for an hour or two. This
is due to the “burn-in” of internal paints
and lubricants used in the manufacturing
process.
3.
Keep the lower control compartment clean
by vacuuming or brushing at least twice a
year. More frequent cleaning may be required
due to excessive lint from carpeting, bedding
materials, etc. It is important that control
compartments, burners and circulating air
passageways of the appliance be kept clean
and clear of obstruction of ventilating and
combustion air.
4.
Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re-
lighting, refer to the lighting instructions
in this manual. Instructions are also found
on a pull-out panel located on the floor of
the appliance.
5.
Always keep the appliance area clear and
free from combustible materials, gasoline
and other flammable vapors and liquids.
6.
Remember, Millivolt appliances have a
continuous burning pilot flame. Exercise cau-
tion when using products with combustible
vapors.

Operation of millivolt and electronic gas
control systems are different. Before lighting
and operating your appliance determine if
you have a millivolt or electronic appliance.
