1.4 EPA Loading
For EPA Certification testing, wood logs were 16 ± 1 inches long and the specie used was
beech.
1.4.1 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.
1.4.2 High burn rate
Open the air control completely. Place eight small
pieces (2"x2") of wood in the firebox crossing
them at the greatest possible angle. Criss cross
15 kindling wood pieces on the small pieces
of wood in three to 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 of approximatively 4"x4" or 3"x3". Add the load in an
East-West configuration divided in 3 columns: 2 smallest logs in the back, 2 logs in the middle
and 2 logs in the front. Leave one inch of air space between the rear bricks and the first column,
another one inch between the first two columns, and finally leave no space between the second
and the third column. Let the door ajar to leave a space of one inch on the door handle’s side
for 3 minutes and then close the door.
1.4.3 Medium and low burn rate
On a 2" coal bed that is still slightly red, place six logs of approximatively 4"x4" or 5"x5" Add the
load in an East-West configuration divided in 3 columns: 2 logs in the back, 2 logs in the middle
and 2 logs in the front. The distance between the logs and the rear brick shall be approximately
1 inch. There should be one inch of air space between all the columns. Let the door ajar at 90°
for approximately 6 min. Then, close the door with the primary air control open. Leave to burn
with the primary air control open for approximately 5 more minutes, then close the primary air
control halfway. After another 5 minutes, close the primary air control completely for the low
burn rate and leave it halfway for the medium burn rate.

15From door opening. The depth of the hearth extension in front of the insert is included in the calculation of the oor protector’s dimensions. The
masonry hearth should be at least 6" (152 mm) higher than the combustible oor in front of it and a oor 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 6" (152 mm), the non-combustible (B)
oor protection in front of the insert should have an R value equal or greater than 2.00 and shall extend 27" (686 mm) in front of the unit.

If the value (D) is negative or zero, additional floor protection in front of the unit is not needed
because the masonry fireplace hearth extension is long enough. If the value (D) is positive, an
additional floor protection in front of the hearth extension at least equivalent to the result (D)
must be added.
2.2.1 Installation Raised of 6" (152 mm) and Less
If non-combustible material floor protection needs to be added in front of and level with the
hearth extension of the masonry fireplace (F = 6" [152 mm) or less), an R-value equal to or
greater than 2.00 is required and should extend at least 27" (686 mm) in front of the unit (B).
Refer to «Additional Floor Protection - Not Raised Installation»
2.2.2 Installation Raised of More Than 6" (152 mm)
If the extension of the masonry hearth is raised at least 6" (152mm) from the floor protection, a non-
combustible material, without an R-value, must extend at least 16" (406 mm in USA) or 18" (457 mm
in Canada) in front of the unit (B). Refer to «Additional Floor Protection - Raised Installation».
2.3 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.

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
16 Information as reported by manufacturers and other resources.
17 Horizontal still air can’t be «stack» to accumulate R-values; each layer must be separated with another non-combustible material.

3. Installing Options on Your Product and Replacing Parts
3.1 Replacement and Adjustment
3.1.1 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.
3.1.2 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.
