1Recommended heating area and maximum burn time may vary subject to location in home, chimney draft,heat loss factors, climate, fuel type
and other variables. The recommended heated area for a given appliance is dened by the manufacturer as its capacity to maintain a minimum
acceptable temperature in the designated area in case of a power failure.
2The overall rebox calculation is an approximation and is not intended to be used for loading. This volume includes a buffer zone to allow an easier
fuel insertion, prevent ash spillage and allow the air wash to work properly.
3The maximum heat output (dry cordwood) is based on a loading density varying between 15 lb/ft3and 20 lb/ft3. Other performances are based on
a fuel load prescribed by the standard. The specied loading density varies between 7 lb/ft³ and 12 lb/ft3. The moisture content is between 19%
and 25%.
4As measured per CSA B415.1-10 stack loss method.
5Higher Heating Value of the fuel.
6Lower Heating Value of the fuel.
7Optimum overall efciency at a specic burn rate (LHV).
8The optimum heat transfer efciency is for the low burn rate and represents the appliance's ability to convert the energy contained in the wood logs
into energy transferred to the room in the form of heat and does not take into account the chemical losses during combustion.
9This appliance is ofcially tested and certied by an independent agency.

2.4 EPA Loading
For EPA Certification testing, wood logs were 16 ± 1 inches long and the specie used was
beech.
2.4.1 Air control
The air control is located underneath the ash shelf. To open
the air control, push the air control handle completely to the
left (High). This will increase the burn rate. To close the air
control, push the air control handle completely to the right
(Low). This will decrease the burn rate.
2.4.2 High burn rate
Open the air control completely. Place height small pieces
(2 1/2" x 2 1/2" approximately) of wood in two layers in the
firebox crossing them at the greatest possible angle. Criss
cross 15 to 20 kindling wood pieces (1"x1" approximately) on
the small pieces of wood in three or four layers at the greatest possible angle. Tie knot with five
sheets of paper and place them on top of the kindling wood. Light up the paper and let the door
ajar at 90° until all the kindling wood is on fire. Close the door. When there is no more fire in the
front of the firebox and there are only faint flames on the wood in the back of the firebox, break
ashes, level the coal bed and put six logs in the firebox. Put 3 pieces centered on the coal bed,
without air space between them. Leave one inch of air space between the rear firebrick and the
first piece. The three other pieces should be added on top of the first 3, still in an East-West
configuration. Let the door ajar at 90° for 1 minute and then close the door.
2.4.3 Medium and low burn rate
On a two inches thick coal bed that is still red, place three logs centered on the coal bed in an
East-West orientation. There should be air space between each log and between the logs and
the bricks. The three other pieces should be added on top of the first three, in an East-West
orientation but slightly angled of 10° still with air space between each log and the bricks. Let
the door ajar at 90° for approximately 5 min. Then, close the door with the primary air control
open. Leave to burn with the primary air control open for approximately 10 more minutes and
then close the primary air control completely for the low burn rate and halfway for the medium
burn rate. For better results, close the air control gradually from the closing of the door to the
complete closing of the air control.

3. Clearances to Combustible Material
The clearances shown in this section have been determined by tests according to procedures
set out in safety standards ULC S627 (Canada), UL 1482 (U.S.A.) and UL 737 (U.S.A.). When
the stove is installed so that its surfaces are at or beyond the minimum clearances specified,
combustible surfaces will not overheat under normal and even abnormal operating conditions.
No part of the stove or flue pipe may be located closer to combustibles than the minimum
clearance figures given.
Clearances may only be reduced by means approved by the regulatory authority.
The clearances to combustible walls may be slightly different in Canada and the U.S.A. and may
also differ depending on whether single or double wall flue pipe is used. Make sure to choose
the correct clearance for the stove location and type of flue pipe.
The clearances of the appliance and the flue pipes must be met individually, meaning the appliance
cannot be installed closer to the combustible materials than the single or double wall pipe allows.
For a safe way to reduce clearances refer to section"5. Reducing Wall and Ceiling Clearances Safely"
of this manual.

4. Floor Protection
This stove is designed to prevent the floor from overheating. However, it must be placed on a
non-flammable surface to protect the floor from hot embers that may fall during loading.
The floor protection must be a continuous, non combustible material, such as steel with a minimum
thickness of 0.015" (0.38 mm) or ceramic tiles sealed together with grout. Cement board, brick, or
any other approved or listed material suited for floor protection. No R factor required.
Any type of tile will require a continuous non combustible sheet beneath to prevent the possibility
of embers falling through to the combustible floor if cracks or separation should occur in the
finished surface. Check local codes for approved alternatives.
No protection is required if the unit is installed on a non-combustible floor (ex: concrete).

appliance and/or within the area extending horizontally at least 450 mm (18 in) beyond the appliance on any side equipped with a door, and at least
200 mm (8 in) beyond the appliance on other sides, shall be protected by a continuous, durable, non-combustible pad that will ember protection. The
450 mm (18 in) ember protection required on any side with a door shall extend for the full width of the appliance plus the 200 mm (8 in) required
on each side of the appliance without a door. Where the appliance is installed less than 200 mm (8 in) from a wall, the ember pad need only extend
to the base of the wall. An ember pad shall not be placed on top of a carpet unless the pad is structurally supported to prevent displacement and
distortion.
2The oor protection at the back of the stove is limited to the stove’s required clearance if such clearance is smaller than 8 inches (203 mm).

5. Reducing Wall and Ceiling Clearances Safely
It is often desired to use as little space as possible when installing
a wood stove. To do this, it is possible to reduce the clearances
safely and install the stove closer to the walls by permanently
installing a heat shield between the stove and the flammable
material.
The rules for heat shields are sometimes complicated. Read
and apply the instructions carefully. Some regions may have
different regulations. Consult the local building code or contact
the fire department for restrictions, inspection and installation
requirements in the area.
Warning: To reduce the clearances of an appliance using a single wall pipe connector, the use of a heat
shield certified with the single wall pipe connector to be used as close as 6" from combustible materials
must be used. Only in this case, the same clearances as a certified double wall pipe connector can be
used. Refer to the booklet in the screen options to obtain the dimensions to be respected.
5.1 Shield Construction Rules
− Adhesives used in shield construction must not ignite or lose adhesive qualities at temperatures
likely to be encountered.
− Mounting hardware which extends from the shield surface into combustibles may be used only
at the edges of the shield.
− Mounting hardware must allow full vertical ventilation.
A) Minimum clearance between the appliance top and an unshielded combustible ceiling:
39 7/8" (1013 mm)
B) Shield extension above the appliance: 20" (500 mm)
C) Minimum space behind the shield: 1" (25 mm). In Canada 7/8" (21 mm)
D) Clearance along the bottom of the shield: minimum 1" (25 mm) and maximum 3" (75 mm)
E) Minimum clearance along the top of the shield: 3" (75 mm)
F) Mounting hardware must not be located closer than 8" (200 mm) from the vertical centre line of
the appliance.
G) Edge clearance for ceiling shields to side and back walls: 3" (75 mm)
H) Shield extension beyond each side of the appliance: 18" (450 mm)
