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 defined by the manufacturer as its capacity to maintain a minimum
acceptable temperature in the designated area in case of a power failure.
2The overall firebox 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 specified 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 efficiency at a specific burn rate (LHV).
8The optimum heat transfer efficiency 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 officially tested and certified by an independent agency.

2.4 EPA Loading Procedure
The loading methods shown below are those that were used during emissions certification.
2.4.1 Air control
The air control is located above the door. To open
the air control, insert the removable handle onto
the air control and push the air control handle
completely to the right (High). This will increase
the burn rate. To close the air control, push the
air control handle completely to the left (Low).
This will decrease the burn rate. Do not leave
the handle on the air control after use, as it
will get very hot.
2.4.2 High burn rate (primary air control
open)
Open the air control completely. Criss cross 6 kindling wood pieces in the back of the firebox.
Then, place six small pieces (2”x2”) of wood on the kindling crossing them at the greatest
possible angle. Criss cross ten others kindling wood pieces on the small pieces of wood. Tie
knot with five sheets of paper and place them on top of the kindling wood. Light up the paper
and let the door completely open for two minutes. Close the door.
When the kindling and the small pieces of wood are almost completely burnt out and it is
possible to break them into pieces, level the coal bed and put four logs in the firebox in an east-
west orientation. Place a medium log (about 4”x4”) in front of the combustion chamber and the
biggest log (about 5”x5”) in the back of the combustion chamber. Place the last two medium
pieces on top of the two others in an orientation that points to the right. Do not leave space
between the pieces. Let the door open ajar at 90° for 5 minutes and close the door.
2.4.3 Medium and low burn rate
On a 2” coal bed that is still red, place five logs of approximatively 4”x4” or 3”x3” with an east-
west orientation. Place two logs on the coal bed with approximatively 4” between them and the
other three on top. There should be air space between each logs and between the logs and the
bricks. Let the door ajar at 90° for 5 minutes and then close the door with the primary air control
fully 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.
A
WARNING
Before opening the door completely to add
wood to the insert, the fan must be turned OFF
to avoid blowing ash outside the combustion
chamber. Refer to section "5.1 Blower" of the
owner's manual for how to turn OFF the fan.

3.2 Floor Protection
It is necessary to have a floor protection made of non-combustible materials that meets the
measurements specified in the "Table 1 : Floor Protection" below.

3.3 R Value
There are two ways to calculate the R-value of the floor protection. First, by adding the R-values of
materials used, or by the conversion if the K factor and thickness of the floor protection are given.
To calculate the total R value from R values of the materials used, simply add the R-values of
materials. If the result is equal to or greater than the R-value requirements, the combination is
acceptable. R-values of some selected materials are shown below.

Cement mortar 5.00 0.2
Common brick 5.00 0.2
Face brick 9.00 0.11
1From door opening. The depth of the hearth extension in front of the insert is included in the calculation of the floor protector’s dimensions. The
masonry hearth should be at least 5" (127 mm) higher than the combustible floor in front of it and a floor protection must extend at least 16"
(406 mm USA) and at least 18" (457 mm Canada) without an R value. If the hearth elevation is lower than 5" (127 mm), the non-combustible (B)
floor protection in front of the insert should have an R value equal or greater than 1.00 and shall extend 23" (584 mm) in front of the unit.

Limestone 6.5 0.153
Ceramic board (Fibremax) 0.450 2.2
Horizontal still air (1/8" thick)10.135 0,920**
Exemple:
Required floor protection R of 1.00. Proposed materials: four inches of brick and one inch of
Durock® board:
Four inches of brick (R = 4 x 0,2 = 0,8) plus 1 inch of Durock® (R = 1 x 0.52 = 0.52).
0.8 + 0.52 = 1.32.
This R value is larger than the required 1.00 and is therefore acceptable.
In the case of a known K and thickness of alternative materials to be used in combination,
convert all K values to R by dividing the thickness of each material by its K value. Add R values
of the proposed materials as shown in the previous example.
Exemple:
K value = 0.75
Thickness = 1
R value = Thickness/K = 1/0.75 = 1.33
1Horizontal still air can’t be «stack» to accumulate R-values; each layer must be separated with another non-combustible material.

4. Installing Options on Your Product and Replacing Parts
4.1 Replacement and Adjustment
4.1.1 Door
Note: The images shown are for guidance only and may be different from your product, but
the assembly remains the same.
In order for the insert to burn at its best efficiency, the door must provide a perfect seal with the
firebox. Therefore, the gasket should be inspected periodically to check for a good seal. The
tightness of the door seal can be verified by closing and latching the door on a strip of paper.
The test must be performed all around the door. If the paper slips out easily anywhere, either
adjust the door or replace the gasket.
4.1.2 Adjustment
The gasket seal may be improved with a simple latch mechanism adjustment:
1. Remove the split pin by pulling and turning it using pliers.
2. Turn the handle one counterclockwise turn to increase pressure.
3. Reinstall the split pin with a small hammer.
