IMPORTANT SAFETY AND WARNIING
INFORMATION
READ THIS MANUAL IN ITS ENTIRETY AND UNDERSTAND THESE RULES TO FOLLOW FOR SAFETY.
1. When this room heater is not properly installed, a house fire
may result. To reduce the risk of fire, follow the installation
instructions. Contact local building or fire officials about
restrictions and installation inspection requirements in your
area.
2. Wear gloves during installation to avoid injury from sharp
edges on the insert and/or its parts.
3. This unit is designed and engineered to burn only dry, wellseasoned wood. Burning wet wood will greatly reduce your
inserts efficiency, produce excessive amounts of smoke and
can cause dangerous chimney fires due to creosote buildup.
4. Before opening the door, the draft control must be fully open
to avoid possible combustion flash (ignition of hot volatile
gases as the door is opened).
5. Never use gasoline, gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or ’freshenup’
a fire in this heater. Keep all such liquids well away from the
heater while it is in use.
6. While burning, fuel utilizes oxygen from the air in the room.
Be sure to allow an adequate amount of fresh air into the
room where the insert is burning.
7. The outside surface of the insert will be hot while burning
properly and can set items like clothing and curtains on fire.
Keep furnishings and other combustible materials away from
the insert. Using the heat from the insert to dry wet clothing
can be hazardous if clothes are placed too near the surface
of the insert.
8. Do not allow children to play near the insert without close
supervision. Do not touch the insert while it is burning. Use
extreme caution while the unit is in use. Surface temperatures
become dangerously hot and can cause serious burns.
9. Do not allow anyone to operate the insert who is not familiar
with the operating instructions.
10. Attempts to achieve heat output rates that exceed insert design
specifications can result in permanent damage to the insert.
Never leave your insert unattended on high burn rates. This
may cause overfiring. Overfiring the insert may cause a house
fire. If the insert glows, you are overfiring.
11. Keep a water hose or hand-operated fire extinguisher close
for safety.
12. Smoke Detectors - Since there are always several potential
sources of fire in any home, we recommend installing smoke
detectors. If possible, install the smoke detector in a hallway
adjacent to the room (to reduce the possibility of occasional
false activation from the heat produced by the insert). If your
local code requires a smoke detector be installed within the
same room, you must follow the requirements of your local
code. Check with your local building department for requirements in your area.
13. Inspect your chimney at least once a month during the burning season to check for soot and creosote accumulations.
Any accumulations over 1/8” thick should be removed by a
professional chimney sweep. Do not attempt to burn out heavy
creosote accumulations with a hot fire. If large accumulations
are occurring, review your burning procedures.
14. If a creosote fire should develop, the fire department should
be called immediately and then attempts should be made to
control the fire until assistance arrives. If a “runaway” fire
should develop causing over-heating of the insert, the door
and draft regulators should be closed immediately. The fire
should die down once deprived of oxygen. After a severe
chimney fire, the complete chimney system should be checked
before further use.
15. Do Not Use Grate Or Elevate Fire - Build Wood Fire Directly
On Hearth (firebrick). Do not use andirons or other methods
of supporting the fuel.
16. Please read this entire manual before you install and use your
new room heater. Failure to follow instructions may result in
property damage, bodily injury, or even death.
17. Check all local building and safety codes before installation.
The installation instructions and appropriate code requirements must be followed exactly and without compromise.
In the absence of local codes the following standards and
codes must be followed.
18. In the U.S.A, install in accordance with the National Fire
Protection Association’s Code, NFPA 211, Standards for
Chimneys, Fireplaces, Vents and Solid-Fuel-Burning Appliances, or similar regulations, may apply to the installation of
a Solid-Fuel-Burning appliance in your area. In Canada, the
guideline is established by the CSA Standard, CAN/CSA-B365M93, Installation Code for Solid-Fuel-Burning Appliances and
Equipment.
19. Do not connect to any air distribution duct or system.
20. WARNING: BURNING IMPROPER FUEL (I.E. CHARCOAL)
CAN RESULT IN CARBON MONOXIDE POISONING, WHICH
MAY LEAD TO DEATH!
21. Carbon Monoxide Poisoning – early signs of carbon monox-
ide poisoning resemble the flu with headaches, dizziness, or
nausea. If you have these signs, get fresh air at once! Have
the heater inspected by a qualified service technician. Some
people are more affected by carbon monoxide than others.
These include pregnant women, people with heart or lung
disease or anemia, those under the influence of alcohol, and
those at high altitudes.
22. Failure to use manufacturer provided parts, variations in
techniques and construction materials or practices other than
those described in this manual may create a fire hazard and
void the limited warranty.
23. Do not make any make-shift compromises during installation.
Any modification or alteration may result in damage to the
appliance or dwelling and will void the warranty, certification
and listings of this unit.
24. These appliances are designed as supplemental heaters.
Therefore, it is advisable to have an alternate heat source
when installed in a dwelling.
25. Do Not Overfire – If Heater or Chimney Connector Glows,
You Are Overfiring.
26. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING
ANOTHER APPLIANCE.

This manual describes the installation and operation of these non-catalytic
wood heaters. These heaters meet the U.S. Environmental Protection
Agency’s emissions limits for wood heaters sold on or after July 1, 1990.
This heater has been developed, tested and constructed in accordance
with the requirements of UL 1482, ULC S628 and HUD standards and
is listed by OMNI Test Laboratories, Portland, OR. It has been approved
for residential and alcove installations.
DRAFT REQUIREMENTS
read greater than .04’ W.C. (inches water column) and less than .08”
W.C. As per NFPA-211 standard (see paragraph below), the installer
must take into account all variables within the installation and install the
appliance in such a manner that satisfies the draft requirements of the
appliance. See Chimney Guidelines below to assist you in selecting the
proper venting system for your installation.
American National Standards Institute ANSI/NFPA 211, Standard for
Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances
- See Draft Section: A chimney or vent shall be so designed and con-
structed to develop a flow sufficient to completely remove all flue and
vent gases to the outside atmosphere. The venting system shall satisfy
the draft requirements of the connected appliance in accordance with the
manufacturer’s instructions.
Your wood fireplace insert is dependent upon a properly functioning
chimney for optimum performance. It is a high efficiency appliance that
loses much less heat up the chimney than older appliances and fireplaces.
For this reason it is important to match the fireplace insert to the chimney.
The chimney has two functions:
1. It draws combustion air into the appliance (without air, no fuel will
burn) and
2. It exhausts combustion by-products. Your new appliance is what is
known as a “natural draft” appliance.
The appliance depends solely on the natural draft of the chimney system
to draw combustion air into the unit. Draft is the force that moves air from
the appliance up into the chimney. The amount of draft in your chimney
depends on the length of the chimney, local geography, nearby obstructions
and other factors. Too much draft may cause excessive temperatures in
the appliance (overfiring). Slow or inadequate draft equals poor combustion and possible smoking problems. The following are some conditions
that may contribute to poor chimney draft:
1. A chimney too large for your appliance.
2. A chimney with not enough height to produce adequate draft.
3. A chimney with excessive height (this may allow exhaust to cool too
much before exiting, which will stall the rate the exhaust exits).
4. Offsets in the venting system are too restrictive (see Chimney Guide-
lines).
Inadequate draft will cause the appliance to leak smoke into the room
through the fireplace insert and the chimney connector joints.
Excessive draft may cause an uncontrollable burn or a glowing red
fireplace insert or chimney part.
Chimney Guidelines:
• This appliance requires approximately 12 feet minimum of “effective
draw” provided by the venting system. As a rule of thumb, every 90
degree total direction change in the venting will result in a loss of
approximately 5 feet of “effective draw.” Example: If two 45 degree
offsets are used, subtract 5 feet from the actual vertical vent height
to determine your “effective draw.” In this case if you had 14 feet of
vertical vent, the effective draw would only be approximately 9 feet
(14 ft. - 5 ft. = 9 ft.), therefore it may be necessary to add additional
height to the venting system.
• In well insulated and weather tight homes, it may be difficult to establish
a good draft up your chimney. The poor draft is caused by a shortage
of air in the house (see Negative Pressure Warning on Page 5).
Chimney Height Requirements
The chimney must extend 3’ (.92m) above the level of roof penetration
and a minimum of 2’ (.61m) higher than any roof surface within 10’
(3m) (see below). Check with your local building officials for additional
requirements for your area.
Overfiring Damage - If the heater or chimney connector glows, you are
overfiring. Other symptoms may include: Cracking, warping or burning
out of components, plated accessories may turn color, stove glass may
develop a haze, which will not come off with cleaning.
Overfiring of a stove or fireplace insert is a condition where excessive
temperatures are reached, beyond the design capabilities of the appliance. The damage that occurs from overfiring is not covered under the
manufacturer’s limited warranty.
Also see Troubleshooting on Page 17.
SELECTING THE PROPER VENTING SYSTEM
The appliance is merely one component of a larger system. The other
equally important component is the venting system. This is necessary for
achieving the required flow of combustion air to the fire chamber and for
safely removing unwanted combustion by-products from the appliance.
If the venting system’s design does not promote these ends, the system
may not function properly. Poorly functioning venting systems may create
performance problems as well as be a safety hazard. A draft test should

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Figure 1 - Chimney Height Requirements
To pass inspection in nearly any jurisdiction, the chimney must meet both
safety and exhaust flow requirements. The (3’ by) 2’ by 10’ rule applies
to both masonry and factory-built chimneys.
* Ref. USA - National Standard, NFPA 211-latest edition and Canada
National Standard CSA B365-01-latest edition. Vents installed with a
listed cap shall terminate in accordance with the terms of the cap’s
listings.
NEGATIVE PRESSURE WARNING
This appliance is not designed to be operated in a negative pressure.
In very airtight homes with large kitchen exhaust fans, furnace cold air
returns, fresh air exchange systems and any other air system in close
proximity to the heating appliance may create a negative pressure in the
same room as the heating appliance. This can create dangerous back
drafting of the fireplace insert and chimney joints, drawing combustion
by-products into the home. Be sure your home has adequate makeup air
to eliminate negative pressures caused by the above-mentioned sources.
Lennox Hearth Products accepts no liability for damages resulting from
negative pressures described above.
Ventilation Requirements - Provide adequate air for combustion. The
fresh air requirements of this appliance must be met within the space
where it will be installed. Ventilation is essential when using a Solid-FuelBurning heater. In well insulated and weather tight homes, it may be
difficult to establish a good draft up the chimney (caused by a shortage
of air in the home). The lack of air is caused by many common household
appliances which exhaust air from the home (such as a furnace, heat
pump, air conditioner, clothes dryer, exhaust fans, fireplaces, and other
fuel burning appliances). Also, the combustion process of this heater
uses oxygen from inside the dwelling. If the available fresh air delivery
in the dwelling is insufficient to support the demands of these appliances,
problems can result (i.e. excessive negative pressure can develop in the
dwelling which will affect the rate at which this appliance can draft thus
resulting in performance problems. To correct this problem it may help
to open a window (preferably on the windward side of the house).
CREOSOTE, FORMATION AND NEED FOR REMOVAL
When wood is burned slowly, it produces tar and other organic vapors,
which combine with expelled moisture to form creosote. The creosote
vapors condense in the relatively cool chimney flue of a slow-burning
fire. As a result, creosote residue accumulates on the flue lining. When
ignited, this creosote makes an extremely hot fire. The chimney and
chimney connector should be inspected at least once monthly during
the heating season to determine if a creosote buildup has occurred. If
creosote has accumulated, it should be removed to reduce the risk of
a chimney fire.
Dry, seasoned wood is that which has been cut, split and allowed to dry
under a covered area where air is free to flow and circulate under and
around the wood (not under a tarp or plastic). Make sure wood is not
stacked directly on the ground, it may absorb moisture from the ground.
It should be allowed to dry in these conditions for a minimum of six
months, preferably one year or more. IT MUST BE UNDERSTOOD THAT
WOOD CANNOT BE LEFT IN ANY KIND OF WET OR DAMP AREA OR IT
WILL NEVER BECOME COMPLETELY SEASONED. Your fireplace insert
will not operate at the level that it is meant to unless you use seasoned,
dry wood. Do not burn driftwood or wood that has been in salt water,
doing so will void your warranty. Do not burn treated wood, coal, garbage,
cardboard, solvents, or colored paper. Burning treated wood, garbage,
solvents, or colored paper may result in the release of toxic fumes. This
type of burning will also void your warranty.
PAINT CURING
If your fireplace insert has plated accessories, be sure to clean it
with a household type glass cleaner and a very soft cloth to remove
any fingerprints and residues prior to the first fire and before any fire
if the gold has been handled or soiled. Do not close the door tightly
during the “Burn-In Period.” Also, open the door frequently (every
5-10 minutes) to keep the gasket from adhering to the curing paint.
Ventilate the house well during these first firings as the paint gives off
carbon dioxide and unpleasant odors. It is recommended that persons
sensitive to an imbalance in the indoor air quality avoid the fireplace insert
during the curing process.
Your new appliance is painted with a high temperature paint that cures
during the first few firings. We recommend that you put your fireplace
insert through a regimen of three burns. The first two should last for 20
minutes each at 250 degrees (the fireplace insert should be allowed to
cool completely between each burn). The third should be a burn of at least
450 degrees F. for 45-60 minutes. The paint will become soft, gummy
and emit non-toxic smoke during these burns. After the fireplace insert
cools down for the third time, the paint will harden. DO NOT BUILD A
LARGE ROARING FIRE UNTIL THIS CURING EFFECT IS COMPLETE OR
YOU MAY DAMAGE THE FINISH OF YOUR STOVE OR INSERT. Spray
can touch-ups should be done only with a high temperature stove paint
(cat. no. H8159), available from all Lennox Hearth Products dealers.
BURN-IN PERIOD
DISPOSAL OF ASHES
Ashes should be scooped out of a cool fireplace insert with a small metal
shovel. Ashes should be placed in a metal container with a tight fitting
lid and moved outdoors immediately. Other waste shall not be placed
in this container. The closed container of ashes should be placed on a
non-combustible floor or on the ground, well away from all combustible
materials, pending final disposal. If the ashes are disposed of by burial in
soil or otherwise locally dispersed, they should be retained in the closed
container until all the cinders have thoroughly cooled. Ashes can ignite
up to 72 hours after removal from the fireplace insert.
FUEL
This unit is designed and engineered to burn, dry, well-seasoned wood
only.
Please be patient with the heat output of your fireplace insert for the first
few weeks. The steel will go through a curing process that eliminates
moisture, which is deep in the steel and firebrick. This moisture will
reduce initial heat output of your fireplace insert and may make it difficult to start. After you have broken in the paint on the fireplace insert
it will be necessary to build hot fires to thoroughly remove the moisture
from the appliance. Running the fireplace insert with the draft fully open
for 1 to 1-1/2 hours after starting and adding generous amounts of fuel
during the first week or two should complete the curing process. We
recommend the use of a thermometer attached to the fireplace insert
top or chimney. Temperatures on the connector pipe should run in the
250-600 degree range.
(DO NOT OVERFIRE THE STOVE OR INSERT
DURING THIS PROCESS. IF THE STOVE OR CHIMNEY BECOMES
RED, REDUCE THE AMOUNT OF AIR ENTERING THE STOVE OR
INSERT IMMEDIATELY).

BRICK INSTALLATION
CAUTION: Wear gloves during brick installation in case of sharp
edges behind the fireplace insert.
Note: Installation of the baffle boards and baffle blankets are easier when
you can still access the flue outlet, (before connecting the flue vent). Be
sure the baffle blankets are placed flat on the baffle boards so as not
to block exhaust flow to the flue. Use a ruler or a piece of kindling to
reach over the baffle blanket to be sure it is completely flat on top of the
baffle boards.
Measure bricks before installing, as per list of dimensions on next page,
to be sure the correct bricks are installed in the correct location.
1. Install bricks #1-26 in the numbered sequence shown in Figure 2.
Important: The secondary burn tubes at the top of the firebox are
supported by a metal bracket. Move this bracket so it is centered
left and right on the tubes. Also make sure the small supporting
brackets on the front and rear tubes are centered and hanging from
the steel rods at the front and rear of the fireplace insert.
2. Next, you will install the baffle boards. All 4 baffle boards included are
the same size which is 15” x 4-3/4”. You will start by installing the
boards in the center part of the unit on top of the secondary tubes to
each side of the baffle support with the 15” side of the baffle board going
from the front to back of the unit. Once you have the first two boards
installed slide the board to the left side of the baffle support all the way
to the left and rear of the unit. You will slide the board to the right side
of the secondary support to the right and rear of the unit. Next you will
install the two remaining boards where you originally installed the first
two boards on each side of the baffle support and pushed against the
rear of the unit. The stainless steel support hanger should be centered
left to right between the sets of baffle boards and placed as shown in
Figure 4.
3. Also included with the unit are two 15” x 10” x 1” thick baffle blankets. Install each blanket above the baffle board to each side of the
secondary support with the 15” side of the blanket from front to rear
of the unit. Make sure that the baffle blankets are to the full rear of
the unit.
4. Also included with the unit are two 15” x 10” x 1” thick baffle blankets. Install each blanket above the baffle board to each side of the
secondary support with the 15” side of the blanket from front to rear
of the unit. Make sure that the baffle blankets are to the full rear of
the unit.
CAUTION: Make sure the baffle blankets are down flat on the
baffle boards, pulled together in the center so that no gaps exists
between them and do not protrude beyond baffle boards. It is
critical that baffle boards and baffle blankets are fully against
the rear of the unit.

HEARTH PROTECTION
The hearth and/or floor protection must be a thermally rated non-combustible hearth/floor protector meeting or exceeding a thermal rating of
k=.84 or equivalent with a listed thickness of 3/8" (9.5mm) minimum in
USA (3/4" - 19mm minimum in Canada). The covering must extend 18”
(450mm) in front of the heater and 8” (200mm) to either side (measured
from door opening in the USA and measured from the side of the unit
in Canada).
Using Alternate Material As Floor / Hearth Protection
The hearth extension or alternate material used as a floor/hearth protector must be constructed of a durable noncombustible material having
an equal or better thermal conductivity value (lower k value) of k =.84
BTU/IN FT2 HR °F or a thermal resistance that equals or exceeds r = 1.19
HR °F FT2 IN/BTU with a minimum thickness of 3/8” in USA or 3/4” in
Canada. With these values, determine the minimum thickness of the
alternate material required using the formula(s) and shown in Table 2
for USA and Table 3 for Canada.
Note: Any noncombustible material having a minimum thickness of
3/8”(9.5 mm) for USA or 3/4” (19mm) in Canada whose k value is less
than .84 or whose r value is more than 1.19 is acceptable. If the alternate
material used has a higher k value or lower r value will require a greater
thickness of the material used. In some cases, if the k value is less or
the r value higher, a thinner material may be used.
Methods of determining floor protection equivalents:
To determine the thickness required for the alternate material when
either the "k" value or "r" value is known, use either the k formula or r
formula.
Example: If Micore 160 Mineral Fiber Board is to be used for the floor
protection, how thick must this material be?
k
= k value per inch of alternate material
M
rM = r value per inch of alternate material
TM = minimum thickness required for alternate material
T
= standard thickness of the alternate material

Table 2 - USA REQUIREMENTS
** If the hearth extension material(s) that is intended to be used is NOT listed
on Table 1, the material can still be used if the material(s) is noncombustible.
However, the manufacturer of the material must provide either the listed k-value
per inch or r-value per inch with listed thickness so that the minimum thickness
required for the hearth can be calculated (per instructions here or as specified
in the NFI Certification Manuals).
Note: Also see NFI (National Fireplace Institute) Certification Manuals showing other acceptable calculation methods and acceptable alternate materials
which can be used.
