INTRODUCTION
The stove models covered in this manual are
Direct-Vent sealed combustion vented gas
stove heaters designed for residential application. Direct-Vent appliances operate with the
combustion chamber isolated from the inside
atmosphere. All air for combustion is brought in
from the outside and exhaust gases are vented
through the same direct vent, vent system.
These millivolt appliances are designed to
operate on either natural or propane gas. A
millivolt gas control valve with piezo ignition
system provides safe, efficient operation.
External electrical power is required to operate
the optional electrically powered components
if installed.
These appliances comply with National
Safety Standards and are tested and listed
by OMNI-Test Laboratories Inc.; Beaverton,
Oregon (Report No. 116-S-08-05) to ANSI
Z21.88-2002 (in Canada, CSA-2.33-2002),
and CAN/CGA-2.17-M91 in both USA and
Canada, as vented gas heaters.
Installation must conform to local codes. In
the absence of local codes, installation must
comply with the current National Fuel Gas Code,
ANSI Z223.1 (NFPA 54). (In Canada, the current
CAN/CGA B149 installation code.) Electrical
wiring must comply with local codes. In the
absence of local codes, installation must be in
accordance with the National Electrical Code,
NFPA 70 - (latest edition). (In Canada, the current
CSA C22.1 Canadian Electric Code.).
GENERAL INFORMATION
Note: Installation and repair should be per formed
by a qualifi ed service person. The appliance
should be inspected annually by a qualifi ed
professional service technician. More frequent
inspections and cleanings may be required due to
excessive lint from carpeting, bedding material,
etc. It is imperative that the control compartment,
burners and circulating air passage ways of the
appliance be kept clean.
S'assurer que le brùleur et le compartiment des
commandes sont propres. Voir les instructions

Lighting Millivolt Appliances
To light millivolt appliances refer to the detailed
lighting instructions found on Page 12 (English) and Page 13 (French). Millivolt appliance
lighting instructions may also be found on the
pull-out lighting instruction labels attached to
the rear stove shield. Refer to Figure 3 on Page
5 for the location of the piezo igniter.
Millivolt appliances are fi tted with a burner ON/OFF
Rocker Switch, located at the right the rear stove
shield as shown in Figure 1. Once the pilot is lit,
the ON/OFF rocker switch will control the appliance
ON/OFF operation. To operate: Toggle the switch
between its ON and OFF positions.

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 operation. 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.
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.
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 qualifi ed service technician at once if any abnormal
condition is observed.
Refer to the maintenance schedule on Page 14
for maintenance tasks, procedures, periodicity and by whom they should be performed.
Always verify proper operation of the appliance
after servicing.
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 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.
IMPORTANT
Turn off gas and any electrical power before servicing the
appliance.
Verify proper operation after
servicing.
Glass Cleaning
Note: Clean glass after fi rst two weeks of operation (after Burn-In period is over).
The viewing glass should be cleaned periodically to remove any build-up caused from the
following:
• During start-up, it is normal for condensation 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 nonammonia based household cleaner and warm
water as desired (a gas stove glass cleaner is
recommended).
WARNING
Do not use abrasive cleaners.
Never clean the glass when it
is hot.
NOTE: DIAGRAMS AND ILLUSTRATIONS ARE NOT TO SCALE.
WARNING
Do not attempt to touch the front
enclosure glass with your hands
while the stove is in use.
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
Ensure stove is completely cold
prior to cleaning or using enamel
touch up paint.

system at test pressures equal to or less
than 1/2 psig (3.5 kPa).
Lower Access Door
Pull open lower door to access Valve Contols
These are direct-vent appliances. They are
designed to operate only with the front glass
enclosure panel properly installed. Generally, the
glass enclosure panel should not be removed
except to gain access to the components within
the fi rebox, and the appliance may only be operated without the front glass enclosure panel in
place for very brief periods of time during initial
appliance checkout and adjustment.
These appliances and their individual shut-off
valves must be disconnected from the gas
supply piping system during any pressure
testing of that system at pressures in excess
of 1/2 psig (3.5 kPa).
OPERATION AND CARE OF YOUR
APPLIANCE
Appliance operation may be controlled through
a remotely located optional wall thermostat or
remote control.
In lieu of remote or remote wall thermostat
operation, the appliance must be operated
directly through the on/off rocker switch located
on the upper right side of the rear shield. See
Figure 1.
If your millivolt appliance is equipped with an
optional wall thermostat kit or remote control
kit and the pilot is lit, the appliance main burner
may be turned on and off with the wall thermostat
or remote control.
Always keep the appliance area clear and free
from combustible materials, gasoline and other
fl ammable liquids.

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 fl ame. Appliances operated
with air shutter openings that are too large will
exhibit fl ames that are blue and transparent.
These weak, blue and transparent fl ames are
termed anemic. If the air shutter opening is too
small sooting may develop.
Burner Flame Appearance
Figure 7
WARNING
Ensure that the front glass panel
is in place and sealed during
adjustment.
ADJUSTMENT
WARNING
The adjustment rod and nearby
appliance surfaces are hot. Exercise caution to avoid injury while
adjusting fl ame appearance.
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 fl ame
continuously. If it appears weak or sooty as
previously described, adjust the air shutter to
a more open position until the desired fl ame
appearance is achieved.
Figure 6
To install the front glass enclosure panel,
proceed as follows:
1. Retrieve the glass door frame. Visually
inspect the gasket on the backside of the
panel. The gasket surface must be clean,
free of irregularities and seated fi rmly.
2. With the stove top off, position the glass
front enclosure panel into the front opening with the gasket facing the relief door
(see Figure 6). Let the bottom of the door
frame gently slide down, then hook the top
fl ange of the glass frame over the top of the
fi rebox frame.
3. Fasten the two latches located beneath the
fi rebox bottom to the glass frame vee-fl ange.
Close both the latches securely.
4. Reinstall the cast iron stove top (read "Caution," on Page 5).
5. Reinstall Trivet.
Sooting is indicated by black puffs developing
at the tips of very long orange fl ames. Sooting
may result in black deposits forming on the
logs, appliance inside surfaces and on exterior
surfaces adjacent to the vent termination.
Sooting is caused by incomplete combustion in
the fl ames and a lack of combustion air entering the air shutter opening. To achieve a warm
yellow to orange fl ame with an orange body
that does not soot, the shutter opening must
be adjusted between these two extremes. No
smoke or soot should be present. Reposition the
logs to ensure they are in the proper pin locations
if the fl ames impinge on any of them.
If the logs are properly positioned and sooting 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.
WARNING
Air shutter adjustment should
only be performed by a qualifi ed
professional service technician.
The adjustment rod and associated adjustable
air shutter is patented technology. Flame adjustments 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 fl ame 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.
Operate the appliance for a period of time as the
effect diminishes, ensuring that the appliance
does not develop sooty fl ames.
