IMPORTANT SAFETY AND WARNING
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 stove and/or its parts.
3. This unit is designed and engineered to burn only dry, wellseasoned wood. Burning wet wood will greatly reduce the
stove’s efficiency, produce excessive amounts of smoke
and can cause dangerous chimney fires due to creosote
build-up.
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. DO NOT USE CHEMICALS OR
FLUIDS TO START THE FIRE.
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 stove is burning.
7. The outside surface of the stove 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 stove. Using the heat from the stove to dry
wet clothing can be hazardous if clothes are placed too
near the surface of the stove.
8. HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING
FURNISHINGS AND COMBUSTIBLE MATERIAL A CONSIDERABLE DISTANCE AWAY. CONTACT MAY CAUSE SKIN BURNS.
Do not allow children to play near the stove without close
supervision. Do not touch the stove 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 stove who is not familiar
with the operating instructions.
10. Attempts to achieve heat output rates that exceed stove
design specifications can result in permanent damage to
the stove. Never leave your stove unattended on high burn
rates. This may cause overfiring. Overfiring the stove may
cause a house fire. If the stove 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 stove). 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 burn-
ing 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 stove, 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-B365-M93, Installation Code for Solid-Fuel-Burning
Appliances and Equipment.
19. DO NOT CONNECT TO OR USE IN CONJUNCTION WITH ANY
AIR DISTRIBUTION DUCTWORK UNLESS SPECIFICALLY
APPROVED FOR SUCH INSTALLATIONS.
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 monoxide 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.
27. DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS SUCH
AS GASOLINE, NAPHTHA OR ENGINE OIL.

TESTING INFORMATION
SELECTING THE PROPER VENTING SYSTEM
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 1482-2010, ULC S627-00 and HUD standards
and is listed by Intertek, Portland, OR. It has been approved for residential
and mobile home installations.
DRAFT REQUIREMENTS
This appliance 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 stove 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 stove and the chimney connector joints.
Excessive draft may cause an uncontrollable burn or a glowing red stove
or chimney part.
Overfiring Damage - If the heater or chimney connector glows, you are
overfiring. Other symptoms may include: Cracking, warping or burning
out of components, stove glass may develop a haze, which will not come
off with cleaning.
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
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 constructed
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.
Chimney Guidelines:
• Thisappliancerequiresapproximately12feetminimumof“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.
• Donotinstallanoffsetwithinthersttwofeetabovetheueoutlet
on the appliance.
• Inwellinsulatedandweathertighthomes,itmaybedifculttoestablish a good draft up your chimney. The poor draft is caused by a
shortage of air in the house. In this situation an Outside Air Kit may
need to be installed (See Negative Pressure Warning on Page 5 and
Outside Combustion Air on Page 12).
Overfiring of a stove 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.

NEGATIVE PRESSURE WARNING
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 Figure 1). Check with your local building officials for additional
requirements for your area.
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.
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 stove and chimney joints, drawing combustion byproducts into the home. Be sure your home has adequate makeup air to
eliminate negative pressures caused by the above-mentioned sources.
Outside air connected to the appliance probably will not resolve such
a problem as the stove or fireplace insert is not the source of negative
pressure. IHP accepts no liability for damages resulting from negative
pressures described here.
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) or
install an optional outside air kit.
