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
excessivelintfromcarpeting,beddingmaterials,
etc. It is important that control compartments,
burners and circulating air passageways of the
appliance be kept clean.
Glass Cleaning
Note: Clean glass after first 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 film
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
CrazingofPorcelainEnamel: Porcelainenamel,
when heated to high temperatures, is subject
to crazing (a very fine and random network of
hairlinecracks onthe surface of the porcelain).
Crazing is a normal occurrence when enamel
is exposed to high temperatures. Your enamel
finish will not be harmed nor will the function
of the stove be impaired.
Repairing Chips: If the enamel finish on your
stove becomes chipped, it can be touched up
using enamel touch-up paint. For ordering
information, see Page 16.

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

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 fixed 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 flame height as desired after
lighting the appliance by rotating the variable
adjustmentcontrol (HI/LO)knob located on the
front of the valve.
BURN-IN PERIOD:
Duringthe firstfewburnsofthis appliancethere
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.
(Serefina 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 qualified service technician.
However, more frequent periodic inspections
and cleanings should be performed by the
homeowner. Homeowner must contact a quali-
fied 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.

BURNER ADJUSTMENTS
The following paragraphs address burner
adjustment concerns and procedures.
Flame Appearance and Sooting:
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large will
exhibit flames that are blue and transparent.
These weak, blue and transparent flames are
termed anemic. If the air shutter opening is too
small sooting may develop.
Open both Latches as shown.
Figure 4
3. Reach under the bottom front of the front
glass enclosure and pull it forward as
shown in Figure 5.
Figure 5
4.Liftglassassemblyupandoutandcarefully
set aside in a safe place (see Figure 6).
Figure 6
Sooting is indicated by black puffs developing
at the tips of very long orange flames. Sooting
may result in black deposits forming on the
logs, appliance inside surfaces and on exterior
surfaces adjacent to the vent termination.
Sootingiscaused by incompletecombustionin
the flames and a lack of combustion air enter-
ing the air shutter opening. To achieve a warm
yellow to orange flame with an orange body
that does not soot, the shutter opening must
be adjusted between these two extremes. No
smokeorsootshouldbepresent. Repositionthe
logstoensuretheyareintheproperpinlocations
if the flames impinge on any of them.
If the logs are properly positioned and soot-
ing conditions exist, the air shutter opening
on the main burner tube should be adjusted.
Normally, the more offsets in the vent system,
the greater the need for the air shutter to be
opened further.
Burner Flame Appearance
Figure 7
WARNING
Air shutter adjustment should
only be performed by a qualified
professional service techni-
cian.
Initially, always position the air shutter to
the factory setting as shown in Table 5
and Figure 8 (adjustment rod is located in
the lower control area). This can be done
by moving the adjustment rod up or down
accordingly. Allow the burner to operate
for at least 15 minutes. Observe the flame
continuously. If it appears weak or sooty as
previouslydescribed,adjusttheairshutterto
a more open position until the desired flame
appearance is achieved.
The adjustment rod and associated adjustable
airshutterispatentedtechnology.Flameadjust-
ments can be made quickly and accurately to
taste without the need of disassembling the
appliance and waiting for 30 minutes after
each adjustment.
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
open as described in the previous paragraphs.
Operatethe appliance for a period of time as the
effect diminishes, ensuring that the appliance
does not develop sooty flames.

Air Shutter Adjustment Guidelines:
Ifthe burnerflame appearance differsgreatly
from what is shown on Page 6 (see Burner
Flame Appearance), some adjustment from
the factory setting for the air shutter gap may
be necessary (to compensate for variables in
the installation and fuel such as, BTU value /
composition, gas pressure, specific gravity
of gas, altitude, etc.).
Table 6 is provided to aid you in achieving
the correct air shutter adjustment for your
installation.
When satisfied that the appliance operates
properly, proceed to finish the installation.
Leave the control knob in the ON position
and the ON/OFF switch in the OFF position.
Close the lower access door.

Models with Black Painted Finish
The stove body is painted with a quality high-
temperature stove paint. Only use factory sup-
plied Stove Paint for touch-ups (70K99).
Using one small piece of 320 grit sand paper
and lightly sand the blemish so that the edges
are“feathered” or smoothto the touchbetween
the painted and bare sur-faces. Do not let the
sandpaper gumup with paint, as this will cause
scratches on the metal surface. If there are any
scratches,use600gritsandpaperinstead.Mask
off surfaces you do not want painted. Paint
lightly over the bare surface first as this will
act as an under-coat. Then paint over a larger
area in smooth even strokes to blend.
See Burn-In Period on Page 4 for information
on curing the paint.
SMALL AREA TOUCH-UP PAINT
Models with Enamel Finish
If the enamel finish on your stove becomes
chipped, it can be touched up using the
enamel touch-up paint. Follow instructions on
tube for applying. See Page 16 for ordering
information.
Note: When enamel is heated to high tempera-
tures it is subject to crazing (a very fine and
random network ofhairline cracks onthe surface
of the porcelain). Crazing is a normal occurrence
when enamel is exposed to high temperatures.
Your enamel finish will not be harmed nor will
the function of the stove be impaired.

TROUBLESHOOTING THE MILLIVOLT GAS CONTROL SYSTEM
Note: Before troubleshooting the gas control system, be sure external gas shut off valve (located at gas supply inlet) is in the “ON”
position.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION
1. Spark igniter will not light pilot after
repeated triggering of igniter button. A. Defective igniter (no spark at electrode). Checkthegapbetweentheelectrodeandpilot.Itshould
be between 1/8” and 3/16." If the gap is out of this
range, adjust the gap or replace the pilot.
B. Defective or misaligned electrode at pilot
(spark at electrode). Using a match, light pilot. If pilot lights, turn off pilot
and trigger the igniter button again. If pilot lights, an
improper gas mixture caused the bad lighting and a
longer purge period is recommended. If pilot will not
light – check gap at electrode and pilot – It should
be between 1/8” and 3/16". If the gap is out of this
range, adjust the gap or replace the pilot. (Figure 19
on Page 8).
C. Gas supply pressure errant. Check inlet gas pressure. It should be within the limits
as marked on the rating plate.
D. Pilot orifice plugged. Clean or replace pilot orifice.
2. Pilot will not stay lit after
carefully following the lighting
instructions.
A. Defective pilot generator
(thermocouple). Check pilot flame, it must impinge on thermocouple
(Figure 19 on Page 8). Clean and/or adjust pilot for
maximum flame impingement on thermocouple.
Ensure that the connection between the valve and
thermocouple are tight and secure.
3. Pilot burning, no gas to burner, Valve
knob “ON,” Wall Switch “ON.” A. Wall switch or wires defective. Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burner
comeson,replacedefectivewallswitch.Ifokay,jumper
wiresacrosswallswitchwiresatvalve,ifburnercomes
on, wires are faulty or connections are bad.
B. Thermopile may not be generating suf-
ficient millivoltage. Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
325 millivolts minimum with optional wall switch
“OFF.” Replace faulty thermopile if reading is below
specified minimum.
C. Plugged burner orifice. Check burner orifice for stoppage and remove.
4. Frequent pilot/burner outage prob-
lem. A. Pilot flame may be too low or blowing (high) causing the pilot/valve safety to drop out. Clean and/or adjust pilot flame for maximum flame
impingement on thermocouple (Figure 19 on Page
8).
