Type of combustion Non-catalytic
Fuel Type Dry Cordwood
Recommended heating area (sq. ft..)1 250 to 1,200 ft2(23 to 111 m2)
Overall firebox volume21.8 ft3(0.0510 m3)
Loading volume EPA 1.55 ft3(0.0439 m3)
Maximum burn time15 hours
Maximum heat output (dry cordwood)3 45,000 BTU/h (13.2 kW)
Overall heat output rate (min. to max.)2 4 12,124 BTU/h to 26,700 BTU/h
(3.55 kW to 7.83 kW)
Average overall efficiency3
(Dry cordwood) 74 % (HHV)5 79 % (LVH)6
Optimum efficiency7 80 %
Optimum overall efficiency8 79 %
Average particulate emissions rate9 1.8 g/h (EPA / CSA B415.1-10)10
Average CO11 74 g/h
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.
10 Tested and certied in compliance with CFR 40 part 60, subpart AAA, section 60.534(a)(1(ii) and ASTM E3053-17 based on the ALT-125 sent by EPA
on February 28th, 2018.

2.4 EPA Loading
The loading methods shown below are those that were used during emissions certification.
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 (primary air control open)
Open the air control completely. Place six small pieces
(2"x2") of wood in the firebox crossing them at the greatest
possible angle. Criss cross fifteen kindling wood pieces on the small pieces of wood in three
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 and the first row of small pieces of wood is on fire too. 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 four logs in the firebox. Place
the biggest log (about 5"x5") and a medium log (about 4"x4") on the coal bed with a north-south
orientation. Place two other medium logs on the first two with the greatest possible angle. Their
should be air space between each logs and between the logs and the bricks. Let the door ajar
at 90° for approximately two minutes and then close the door.
2.4.3 Medium and low burn rate
On a 2" coal bed that is still slightly red, place five logs of approximatively 4"x4" or 3"x3" with
a north-south orientation. Place three logs on the coal bed and the other two on top with the
greatest possible angle. Their should be air space between each logs and between the logs
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
minutes and then close the primary air control completely for the low burn rate and halfway for
the medium burn rate.

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.
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.

3.1.1 With Heat Shield AC0276216
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.

If the clearance reduction is on the same side as the door handle, position the stove at
a minimum of 6 inches from the side wall (clearance B), otherwise it may be located at
the clearance shown in the table above.
16 Note that to reduce the clearances of an appliance using a single wall pipe connector, the use of a heat shield certied 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 certied double wall

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).

23 Only required under the horizontal section (Ho) of the connector. Must exceed each side of the connector by at least 2 inches (51 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.
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:
47 ¼" (1200 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)
