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 manufacturer's 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,
In USA, NEC, ANSI / NFPA 70-1987.
In Canada, CSA C22.1
2. Local amendments?
3. Is a permit required - cost?
(You may wish to contact your insurance company
4. 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
fireplace 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.
IMPORTANT – THIS APPLIANCE IS NOT
PROVED FOR INSTALLATION INTO A MANUFACTURED (MOBILE) HOME IN CANADA OR IN THE
USA.
State or Regional Codes)
Electrical codes: The blower system has a

CHIMNEY INSPECTION
The existing fireplace should be inspected by a local fire
marshal or qualified installer for adequate serviceability
prior to installing this appliance.
Factory built fireplace (not approved in Canada): If
any portion of the chimney system shows signs of
structural or mechanical weaknesses, such as:
cracks, leaky joints, corroded or warped surfaces.
Look for obvious bulges in the lining, which may indicate the need to replace that section (use a bright
flashlight. Any faulty portion must be repaired or replaced prior to installing this appliance. Also, inspect
the attic to see that the chimney has proper clearance
to combustible framing members.
Masonry fireplace: The chimney should have no
cracks, loose mortar, other signs of deterioration, or
blockage. Any necessary repairs should be done by a
qualified mason.
If the existing fireplace flue system is dirty or has some
obstruction in it, clean it. A dirty chimney can cause
your insert to smoke when refueling, and can result in a
chimney fire. An oversized chimney may result in less
than optimum performance. Installations into a large
masonry chimney may require a liner to improve performance.

PLANNING YOUR INSTALLATION
CLEARANCES
WARNING: IT IS VERY IMPORTANT THAT YOU
OBSERVE THE MINIMUM CLEARANCES. DO NOT
STORE FIREWOOD WITHIN THIS CLEARANCE
SPACE. FAILURE TO MAINTAIN CLEARANCES TO
ALL COMBUSTIBLES MAY RESULT IN A HOUSE
FIRE.
There are listed clearances for your fireplace insert,
which were determined in a Laboratory testing and
must be maintained.
Stove top to mantel: 27" (686 mm)
Stove top to trim: 16" (406 mm)
Stove side to trim: 6" (152 mm)
Stove side to sidewall: 6" (152 mm)
For installation with a combustible mantel or top trim,
Part #16101 deflector must be installed.
DRAFT REQUIREMENTS
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 byproducts 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 (i.e.
an oversized chimney may result in less than optimum
performance. Installations into a large, masonry chimney may require a liner to improve performance). A
draft test should read greater than .04' W.C. (inches
water column) and less than .08" W.C.
American National Standards Institute ANSI/NFPA 211-92,
draft 1-7: 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.
PROVIDE ADEQUATE AIR FOR COMBUSTION
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.
To provide the needed air, crack a window on the windward side of the house.
VENTILATION REQUIREMENTS
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 fuel burning
heater. The combustion process of this heater uses
oxygen from inside the dwelling and it may be necessary to open a window or install a vent to provide makeup air into a dwelling that is well insulated (modern construction standards have resulted in homes that are
highly energy-efficient and that allow little heat loss and
air transfer). Other appliances in the dwelling also contribute to removing air from the dwelling (i.e. clothes
dryers, exhaust fans, fireplaces, and other fuel burning
appliances). 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. See Draft Re-
quirements on this page).

PLANNING YOUR INSTALLATION
FACTORY BUILT FIREPLACES
(Not Approved In Canada)
In the USA, this appliance is approved for installation
into a listed factory built solid fuel burning fireplace (built
to UL 127 or ULC S610 standards). The fireplace firebox must accept the insert without modification other
than removing bolted or screwed together pieces such
as smoke shelf / deflectors, ash lips, screen or door
tracks and damper assemblies, that must be reinstalled
to restore the fireplace to its original operating condition
if the insert is removed and not replaced. The removal
of any part must not alter the integrity or outer shell of
the pre-engineered fireplace cabinet in any way.
Venting Requirements for factory built fireplace:
The fireplace damper must be secured in the open position. This appliance requires the use of a 6” (152 mm)
diameter flex or rigid, UL1777 listed 2100° HT liner or
equivalent. The liner must extend from the flue outlet of
the appliance to termination. Do not face seal over fireplace chimney cooling air systems. Offsets can be handled with an offset adapter (it aligns starter pipe with
fireplace flue). For more information on the offset
adapter, see pages 10 and 26.
WARNING: DO NOT SUBSTITUTE THE HEAT
RATED 2100°HT LINER WITH ANY OTHER TYPE
LINE OR A FIRE MAY RESULT CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS
OF LIFE.

Do not remove brick or mortar form the masonry fireplace to accommodate this appliance. If the fireplace
has been modified to accommodate the fireplace insert,
a metal tag documenting what was modified must be
attached to the fireplace (as required by Clause 5.1.11
it must be secured using screws or nails to the fireplace, in a location readily visible should the fireplace
insert be removed). The lettering shall not be less than
5 mm high.
THIS FIREPLACE HAS BEEN ALTERED TO ACCOMMODATE A FIREPLACE INSERT AND
SHOULD BE INSPECTED BY A QUALIFIED PERSON PRIOR TO RE-USE AS A CONVENTIONAL
FIREPLACE
IMPORTANT: Any opening between the masonry of
the fireplace and the facing masonry must be permanently sealed.
USA Requirements / Masonry Fireplaces - The fire-
place damper must be secured in the open position. In
the USA, a flue extension past the fireplace header is
required as a minimum. A preferred installation is a
positive flue connection (sealing the throat of the chimney). This appliance requires the use of a 6” (152 mm)
diameter flex or rigid single wall pipe, minimum 24 / 25
MSG black or blued steel connector pipe (stainless
steel recommended).
Canada Requirements / Masonry Fireplaces - – This
fireplace insert must be installed into an approved solid
fuel Masonry
built fireplace is not approved). The fireplace damper
must be secured in the open position. The fireplace insert must be installed with a continuous chimney liner of
6” / 152 mm diameter extending from the fireplace insert to the top of the chimney. The chimney liner must

FIREPLACE CHIMNEY MAXIMUM SIZE TO ENSURE
PROPER DRAFT – USA ONLY
Note: Installations in Canada require a full length liner.
The fireplace insert flue size is 6 inches (152 mm) diameter, which is approximately 28 square inches (711
square mm), the minimum. The maximum flue size
should be no more than (3) three times the cross sectional area of the size of the fireplace insert flue collar.
In this case, that would be no larger than a 10 inch (254
mm) diameter stack (area = approx. 85 sq. inches [216
sq. cm]).
Note: Formulas for calculating Area:
Calculating area of a circle:
2
π x r
= Area (π = 3.1416, r = 1/2 diameter)
To calculate area of square or rectangle:
Width x Depth = Area
Notes:
It may be necessary to use a full-length liner to
achieve adequate draft for the appliance. A draft
gauge should read more than .04 W.C.I, but less than
.08 W.C.I. for optimum performance.
This appliance is approved for all heatform style
fireplaces (masonry fireplace with a metal firebox liner).
