Always turn off gas to the pilot (millivolt appli-
ances) 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 rear stove shield.
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.
Glass Cleaning
Note: Clean glass after fi rst two weeks of opera-
tion (after Burn-In period is over).
The viewing glass should be cleaned periodi-
cally to remove any build-up caused from the
following:
• During start-up, it is normal for condensa-
tion to form on the inside of the glass (this
condensation and fog will usually disappear
in a few minutes). This can cause lint, dust
and other airborne particles to cling to the
glass surface.
• Initial curing of the high temperature paint
and burning off of lubricants used in the
manufacturing process may result in a fi lm
on the glass.
• A white coating may form on the glass as a
result of impurities and minerals in the fuel.
It is recommended that the glass be cleaned
two or three times during each heating season,
depending on the circumstances present.
Exterior glass may be cleaned with an non-
ammonia based household cleaner and warm
water as desired (a gas stove glass cleaner is
recommended).
Models with Porcelain Enamel Finish
Crazing of Porcelain Enamel: Porcelain enamel,
when heated to high temperatures, is subject
to crazing (a very fi ne and random network of
hairline cracks on the surface of the porcelain).
Crazing is a normal occurrence when enamel
is exposed to high temperatures. Your enamel
fi nish will not be harmed nor will the function
of the stove be impaired.
Repairing Chips: If the enamel fi nish on your
stove becomes chipped, it can be touched up
using enamel touch-up paint. For ordering
information, see Page 16.
Cleaning Enamel Surfaces: To remove build-up
of dust, dirt or crud from the enamel surfaces,
combine baking soda and a little water to make a
cleaning paste. Use a soft rag to rub the surface
with the mix until the stains are removed.
IMPORTANT
Turn off gas and any electri-
cal power before servicing the
appliance.
Verify proper operation after
servicing.
WARNING
Do not use abrasive cleaners.
Never clean the glass when it
is hot.
WARNING
Do not attempt to touch the front
enclosure glass with your hands
while the stove is in use.
IMPORTANT
Ensure stove is completely cold
prior to cleaning or using enamel
touch up paint.
VARIABLE FLAME HEIGHT
ADJUSTMENT
All Millivolt appliances are equipped with a
variable gas control valve. Flame height for
these models may be adjusted through a range
between fi xed low and high settings by rotating
the HI/LO knob on the valve (see Figure 3),
alternately, while the appliance is in opera-
tion. Adjust the fl ame height as desired after
lighting the appliance by rotating the variable
adjustment control (HI/LO) knob located on the
front of the valve.
BURN-IN PERIOD:
During the fi rst few burns of this appliance there
will be some odor due to the “burn-in” of paints
and lubricants (curing of the high temperature
paint and burning off of lubricants used in the
manufacturing process).
Depending on your use, the burn-in period may
take a few hours or a few days. The dwelling
should be well ventilated during these initial
burns.
If the optional Blower Kit (see Page 10 for
ordering information) is installed, do not turn
on a blower during the Burn-In period. Do not
place anything on the stove surface until the
paint is completely cured.
(Serefi na Models with Black Paint) Do not
attempt to repaint the stove until the paint is
completely cured. If the surface later becomes
stained or marred, it may be lightly sanded and
touched up with spray paint (See Small Area
Paint Touch-Up, Page 8). Paint is available at
your local authorized Lennox Hearth Products
dealer. Never attempt to paint a hot stove.
MAINTENANCE
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualifi ed service technician.
However, more frequent periodic inspections
and cleanings should be performed by the
homeowner. Homeowner must contact a quali-
fi ed service technician at once if any abnormal
condition is observed.
Refer to the maintenance schedule on Page 14
for maintenance tasks, procedures, periodic-
ity and by whom they should be performed.
Always verify proper operation of the appliance
after servicing.
IMPORTANT
Keep your house well ventilated
during the curing process. The
odor and haze emitted by the
curing process can be quite
noticeable and may set off a
smoke detector.
