2. When lit for the rst 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 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.
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 liquids.
6. Remember, Millivolt appliances have a con-
tinuous burning pilot flame. Exercise caution
when using products with combustible vapors.
7. Clean the optional glass doors only when
necessary. Wipe surface with clean, dampened,
soft cloth. Follow with dry, soft towel as desired.
Take care not to scratch the glass surface.

DAMPER AND OUTSIDE AIR CONTROLS
This appliance is tted with a manually controlled
vent damper. The vent damper should be closed
when the appliance is not in use to prevent cold
air from entering the home through the venting
system. The damper is controlled through the
use of a control lever located within the appli-
ance opening at the top center in front of the
rebox lintel (see Figure 5 ). The control lever
snaps into place at either extreme of its range
of motion. When locked in position all the way
to the right, the damper is open. When locked
in position all the way to the left, the damper
is closed.
The damper lever actuates a switch, (see wiring
diagram) which will prevent the appliance main
burner from lighting unless the damper is locked
open. The appliance flue damper must always
remain open when operating.
