kerosene, charcoal lighter fluid, or similar liquids to start or "freshen up" a fire in this heater.
Keep all such liquids well away from the heater
while it is in use.
10. DO NOT OVERFIRE: If heater or chimney connector glows, you are overfiring. Overfiring this
appliance could cause a house fire. Overfiring is
a condition where the appliance is operated at
temperatures above its design capabilities (see
Overfiring, on page 23). Overfiring can be
caused by improper installation, improper operation, lack of maintenance or improper fuel
usage. Damage caused from overfiring is NOT
covered under the manufacturers limited warranty. (see Care and Operation, pages 14 to 17).
11. NEVER LEAVE AN UNATTENDED STOVE
BURNING ON HIGH. Operation of the stove with
the primary air control at its highest burn rate
setting for extended periods can cause dangerous overfiring conditions. The primary air control should only be positioned at the highest
setting during start-up procedures and for short
durations. When leaving the stove unattended
ensure that the primary air control is set to the
low or medium low range.
12. Use a metal container with a tight fitting lid to
dispose of ashes.
13. IN THE EVENT OF A COMPONENT FAILURE,
USE ONLY COMPONENTS PROVIDED BY THE
MANUFACTURER AS REPLACEMENT PARTS.
14. Burning any kind of fuel uses oxygen from the

PLANNING YOUR INSTALLATION
QUESTIONS TO ASK LOCAL BUILDING OFFICIAL
A correct installation is critical and imperative for reducing fire hazards and perilous conditions that can arise
when wood burning appliances are improperly installed.
The installer must follow all of the manufacturers’ instructions.
The installation of a wood burning appliance must conform to local codes and applicable state and federal
requirements. Familiarity with these requirements before installation is essential. Important considerations to
discuss with local building officials include:
1. Applicable codes (i.e. Uniform Mechanical Code,
State or Regional Codes.)?
Electrical codes: Optional Blower Assemblies have a
flexible electrical cord that must be electrically
grounded per local codes or per electrical codes:
In USA, NEC, ANSI/NFPA 70-2002.
In Canada, CSA C22.1
WARNING: ELECTRICAL GROUNDING INSTRUCTIONS: THIS APPLIANCE IS EQUIPPED WITH A
THREE-PRONG (GROUNDING) PLUG FOR YOUR
PROTECTION AGAINST SHOCK HAZARD AND
SHOULD BE PLUGGED DIRECTLY INTO A PROPERLY GROUNDED THREE-PRONG RECEPTACLE.
DO NOT CUT OR REMOVE THE GROUNDING
PRONG FROM THIS PLUG. DO NOT ROUTE
POWER CORD UNDER OR IN FRONT OF APPLIANCE.
2. Local amendments?
3. Is a permit required - cost?
(You may wish to contact your insurance company
to ask if they require this).
4. Is outside combustion air required?
5. Rooms where the installation is not allowed?
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.
SELECTING A LOCATION
The design of your home and where you place your
stove will determine its value as a source of heat. A
wood stove depends primarily on air circulation (convection) to disperse its heat, and therefore, a central
location is often best. There are other practical considerations, which must be considered before a final selection of locations is made:
♦ Existing Chimneys
♦ Wood Storage
♦ Aesthetic Considerations
♦ Roof Design (Rafter Locations & Roof Pitch)
♦ Room Traffic
♦ Proximity to Combustibles
♦ Electrical Wiring
The installation of this stove will require some research.
Once your options are determined, consult with your
local building department who will be able to give you
the necessary installation requirements for your area (Is
a building permit required, rooms where installation may
not be allowed etc.).
WARNING: CHECK ALL LOCAL BUILDING AND
SAFETY CODES BEFORE INSTALLATION. THE INSTALLATION INSTRUCTIONS AND APPROPRIATE
CODE REQUIREMENTS MUST BE FOLLOWED EXACTLY AND WITHOUT COMPROMISE. ALTERATIONS TO THE STOVE ARE NOT ALLOWED. DO
NOT CONNECT THE STOVE TO A CHIMNEY SYSTEM SERVING ANOTHER STOVE, APPLIANCE, OR
ANY AIR DISTRIBUTION DUCT. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL VOID THE
MANUFACTURERS WARRANTY.
If you plan to vent your stove into an existing masonry
chimney, have the chimney inspected by a local fire
marshal or qualified installer. Remember that a stove's
performance is heavily influenced by the chimney and
its location on the roof. An oversized flue may not provide effective draw, and a flue liner may be required
(see Draft Requirements, page 11). Consult your dealer
or qualified installer before final selection is made.
This stove requires pre-installation work to be completed before installation can take place. This may include modification for flue and chimney.
NOTE – This appliance IS
into a Manufactured (Mobile) Home in Canada and
the USA.

and are not measurements for building an Alcove. You
will need to consider these clearances, as well as
other dimensional requirements before you build the
alcove and install this appliance.
REDUCED MASONRY STRUCTURE CLEARANCE
(ALCOVE)
Your stove can be installed in a masonry structure with
reduced clearances if the structure was built to National
Building Code for fireplaces and chimneys (UBC 37).
The firebox of the masonry structure must be of adequate size to allow a minimum of 6” (152.4 mm) clearance to the sides and top of the stove and 2” (50.8 mm)
clearance to the rear. All stove models must be installed
on their original listed legs or base unless otherwise
specified by OMNI Testing Laboratory.
The minimum venting requirement is a listed chimney
liner that extends from the flue collar of the stove to the
first tile liner of the chimney where it is sealed. All joints
and connections must be made airtight to prevent leaking and
downdrafts.
PROTECTED WALL CLEARANCE
Some local codes will allow reduced clearances when
the stove is installed adjacent to a protected wall system.
Your local building official must approve the variance.
Normally, the protected wall system is defined as a noncombustible material with a minimum of 1” (25.4 mm) air
space behind. Check your local building codes or with a
qualified installer (Ref. NFPA 211).

INSTALLATION
AIR INTAKE COVER
The pedestal is equipped with an air intake cover (located at the top front of the pedestal). The air intake
cover should be adjusted to the open position if outside
combustion air is NOT provided. If outside combustion
air is provided, adjust to the closed position (see illustration to the right).
Air Intake

OUTSIDE AIR
In all manufactured (mobile) homes and in many site
built residences (subject to local code), a stove may be
required to use outside air for combustion. A 5 ¼” (133
mm) square outside air floor duct is available through
your dealer.
Stove
Outside
Air Floor
Duct
This stove can take in outside air directly through the
base. This type installation requires a hole through the
floor protector and the use of outside air floor duct (catalog # 14M67) to penetrate into the air space below the
home. When outside air is hooked up, the Air Intake
Cover must be adjusted to the closed position (see Air
Intake Cover section on this page).
NOTE: Because the base sits 1” (25.4 mm) off the floor,
the outside air floor duct can be positioned along the
front to rear center line under the pedestal, but as close
to the opening in the base as location permits. The air
duct opening must be protected from any possible obstruction including loose floor insulation.
MANUFACTURED (MOBILE) HOME REQUIREMENTS
This stove is certified as a Room Heater, Solid Fuel Type
and may be used in Manufactured Housing providing the
following requirements are followed:
• An outside air inlet must be provided for combustion
and be unrestricted while unit is in use.
• WARNING: DO NOT INSTALL IN SLEEPING
ROOM.
• Regulations require that the appliance must be secured to the floor and grounded to the chassis. See
Securing the Stove to the Floor (and) Grounding
Stove.
• Required venting is 6” (152 mm) diameter Type LVent connector pipe with listed factory-built 103HT
chimney suitable for use with solid fuels or a code
approved masonry chimney. Approved brands of factory built chimney are listed in this manual. A rain
cap and spark arrestor is required (see Clearances,
pages 6 & 7).
• CAUTION: THE STRUCTURAL INTEGRITY OF
THE MOBILE HOME FLOOR, WALL, AND CEIL-
Floor Protector
ING/ROOF MUST BE MAINTAINED.
• The chimney must provide for a section joint so that
any parts extending above 13’ 6” (411 cm) from
ground level can be removed for transportation of the
mobile dwelling.

INSTALLATION
SECURING THE STOVE TO THE FLOOR
Manufactured (Mobile) Homes Only
Once the outside air floor duct is in position, replace the
floor protector. Make sure that the floor protector's hole is
aligned with the outside air opening. Next position and
align the stove on the hearth pad. Manufactured (mobile)
home installations require that the stove be secured to
the floor. This ensures that the stove will not shift when
the manufactured (mobile) home is moved. To do this,
mark where the holes are to be drilled using a marking
instrument long enough and small enough to fit through
the (4) four holes in the stove base. Mark holes, then
remove the stove. Drill the (4) four holes, with a ¼” (7
mm) drill bit. Drill down through the floor protector and
the manufactured (mobile) home floor. Use ¼” (7 mm)
lag bolts and secure to the manufactured (mobile) home
floor.
NOTE: If the composition of the manufactured (mobile)
home floor is of light particleboard construction, you will
be required to secure the stove with regular hex head
bolts and nuts. This will ensure that the bolts will not rip
out of the floor when the manufactured (mobile) home is
being moved.
GROUNDING STOVE
Manufactured (Mobile) Homes Only
Regulations require that all stoves installed in manufactured (mobile) homes must be grounded. To do this simply attach a piece of No. 8 copper wire, at least 18” (457
mm) in length from the stove to the chassis of the manufactured (mobile) home.
INSTALLING CATALYTIC TEMPERATURE PROBE
Locate the temperature probe with sleeve in the literature
packet. Insert sleeve, then temperature probe into the ¼”
(7 mm) diameter hole on the stove top.
REMOVE ASH DRAWER CLIP
The ash drawer is secured for shipping with a small retaining screw at the top of drawer. Remove and discard
this screw.
TYPES OF CHIMNEYS
The chimney is a vital part of your stove installation. A
properly built masonry chimney or a properly installed
factory built chimney will assure a consistent draft under
a variety of weather conditions (a smoking stove is usually caused by a chimney problem). The stove flue size is
6” (152 mm) diameter, which is approximately 28 square
inches (712 square millimeters) minimum. The maximum
flue size should be no more than (3)-three times the
cross sectional area of the size of the stove flue collar. In
this case, that would be no larger than a 10“ (254 mm)
diameter stack, or approximately 85 square inches (216
square centimeters) maximum.
All chimneys must be installed as specified by local
building codes and according to the chimney manufacturer instructions (in the case of a factory built chimney).
See the chimney manufacturer instructions for exact
specifications. Factory built chimneys must comply with
UL 103HT or ULC S629.

ACCEPTABLE CONNECTOR PIPE FOR INSTALLATIONS
For Standard Residential Clearances:
Six 6 inch (152
mm) minimum, single wall, 25 gage minimum thickness,
stove pipe is acceptable. Three (3) pre-drilled holes are
provided in the flue collar for fastening the pipe securely
to the stove. Use sheet metal screws to do this. Additional sections of single wall pipe should be fastened together with at least three (3) sheet metal screws each
section. When connecting to the factory built ceiling support package, use the manufacturer's transition piece,
usually called a dripless connector, to join single wall
pipe to their factory built chimney section.
Minimum Flue Size
: The required minimum diameter
and area required for the flue size is (respectively) 6
inches / 152 mm diameter, which is approximately 28
square inches / 711 square mm. The maximum flue size
should be no more than (3) three times the cross sectional area of the size of the 6 inches / 152 mm diameter
flue collar. In this case, that would be no larger than a 10
inch (254 mm) diameter (area = approx. 85 sq. inches
[216 sq. cm]).
Connection To A Factory Built Chimney
: This space
heater is to be connected to a factory-built chimney conforming to CAN / ULC – S629, Standard for 650°C Factory-Built Chimneys.
For Reduced Residential Clearances
: Type L and
listed double wall connector pipe is acceptable. Install
any factory built brand of pipe according to the manufacturer's instructions.
PAGE 9
INSTALLATION
CHIMNEY INSPECTION
Existing chimneys must be inspected before installing
your stove. Consult your local building department for
chimney code requirements. A masonry chimney must
have a code approved liner. This liner must not have broken or missing pieces. Some non-code masonry chimneys may be brought up to code by being relined. (Consult your dealer or qualified chimney sweep). Factory
built chimneys should also be inspected, first for creosote deposits (which should be removed), and then for
integrity of the stainless steel liner. Look for obvious
bulges in the lining, which may indicate the need to replace that section (use a bright flashlight).
Also, inspect the attic to see that the chimney has proper
clearance to combustible framing members. For interior
masonry chimneys and most factory-built chimneys, this
must be a 2“ (51 mm) air space clearance, which must
not be filled with insulation or any other material. An exterior masonry chimney must have a 1“ (25.4 mm) air
space clearance.
Vapor Barrier At Chimney Penetration
Install all venting components per the Vent Manufacturers installation instructions. Ensure that there is an effective vapor barrier at the location where the chimney
penetrates to the exterior of the structure. This can be
accomplished by applying a non-hardening waterproof
sealant to the following components:
• Around the chimney at the point where the storm
collar will meet the chimney just above the Flashing.
• Along the vertical seam of the chimney pipe, where it
is exposed to the weather.
• On each nail head on the flashing.
• Around the chimney at the point where the storm
collar will meet the chimney just above the flashing.
Notes:
• On a flat or tarred and graveled roof, nail and seal
the flat roof flashing to the roof on all sides with roofing compound.
• Do not put screws through the flashing into the chimney pipe.
CHIMNEY HEIGHT REQUIREMENTS
The chimney must extend 3 feet (914 mm) above the level
of roof penetration and a minimum of 2 feet (610 mm)
higher than any roof surface within 10 feet (305 cm) (see
below). Check with your local building officials for any additional requirements for your area.
Due to prevailing winds, local terrain, adjacent tall trees, a
hill, or ravine near the home, or adjacent structures, additional chimney height or a special chimney cap may be required to ensure optimum performance.
The 2’ by 10’ Rule for Vent Termination
The top of the flue must be 2’ (610 mm) higher than any
part of the roof within 10’ (305 cm) horizontal and a minimum of 3’ (915 mm) higher than the highest point of roof
penetration.
Requires A Listed
Termination Cap
2’ (610mm)
10’ (305 cm)
3’ (915mm)
For Manufactured (Mobile) Homes Only
: Portions of
the chimney and termination that exceed an elevation of
13½ feet above ground level may be designed to be removed for transporting the manufactured (mobile) home.
