REQUIRED.
POSITIONING THE STOVE
It is very important to position the wood stove in an area that will favour the most efficient heat
distribution throughout the house. The stove should therefore be installed in the room where the
most time is spent, and in the most spacious room possible. Recall that wood stoves produce
radiating heat, the heat we feel when we are close to a wood stove. A wood stove also functions by
convection, that is through the displacement of hot air accelerated upwards and its replacement with
cooler air at the floor level. The stove’s convection effect is facilitated by the installation of a
blower.

CLEARANCES TO COMBUSTIBLES AND FLOOR PROTECTOR
To install your appliance correctly, it is extremely important to respect all clearances to any
combustibles as indicated on your stove’s certification label.

Note 2
*Steel with a minimum thickness of 0.015’’ (0.38 mm) or ceramic tiles sealed together
with grout. No protection is required if the unit is installed on a non-combustible floor
(ex: concrete).
Note 1 : The floor protection at the back of the stove is limited to the stove’s required
clearance if such clearance is smaller than 8 inches (205 mm).
Note 2 : Only required under the horizontal section of the connector. Must exceed
each side of the connector by at least 2 inches (51 mm).
Reduced clearances using shielding
You may decrease the clearances by installing heat radiation shields between the walls or
the ceiling and the stove. These heat radiation shields must be installed permanently, and
can include sheet metal, a rigid non-combustible sheet or a masonry wall.
Clearances of not less than 1" (25 mm) and not more than 3" (76 mm) between the
bottom of the shield and the floor and not less than 3" (76 mm) between the top of the
shield and the ceiling must be respected to allow vertical air circulation behind the shield.
The shield must extend 20" (500 mm) above the stove top and 18" (450mm) to each side
of the stove (see graphic 1).
Following the installation of such a heat radiation shield, the clearances mentioned on the
stove certification plate may be reduced as stated in the following table.

CHIMNEY
Your wood stove may be hooked up with a factory built or masonry chimney. If you are
using a factory built chimney, it must comply with UL 103 standards; therefore it must be a
Type HT (2100°F). It is extremely important that it be installed according to the
manufacturer's specifications.
If you are using a masonry chimney, it is important that it be built in compliance with the
specifications of the National Building Code. It must be lined with fire clay bricks, metal or
clay tiles sealed together with fire cement. (Round flues are the most efficient).
The interior diameter of the chimney flues must be identical to the stove's smoke exhaust.
(6”). A flue which is too small may cause draught problems, while a large flue favours
rapid cooling of the gas, and hence the build-up of creosote and the risk of chimney fires.
Note that it is the chimney and not the stove which creates the draught effect; your
stove's performance is directly dependent on an adequate draught from your chimney.

14
The following recommendations may be useful for the installation of your chimney:
1. Do not connect this unit to a chimney flue serving another appliance.
2. It must rise above the roof at least 3' (0.9 mm) from the uppermost point of
contact.
3. The chimney must exceed any part of the building or other obstruction within a
10' (3.04 m) distance by a height of 2' (0.6 m).
4. Installation of an interior chimney is always preferable to an exterior chimney.
Indeed, the interior chimney will, by definition, be hotter than an exterior
chimney, being heated up by the ambient air in the house. Therefore the gas
which circulates will cool more slowly, thus reducing the build-up of creosote
and the risk of chimney fires.
5. The draught caused by the tendency for hot air to rise will be increased with an
interior chimney.
6. Using a fire screen at the extremity of the chimney requires regular inspection in
order to insure that it is not obstructed thus blocking the draught, and it should
be cleaned when necessary.
7. Clean your chimney every 2 months.
CHIMNEY CONNECTOR
Your chimney connector (commonly called stove pipe) and chimney must have the same
diameter as the stove’s exhaust outlet. The stove pipe must be made of aluminized or
cold roll steel with a minimum 24-gauge thickness (0.021" or 0.53 mm). It is strictly
forbidden to use galvanized steel.
The following recommendations may be useful for the installation of your chimney
connector:
Your chimney connector should be assembled in such a way that the male end
(crimped) faces down to prevent creosote dripping outside the joints. Attach each of
the sections to one another with three equidistant metal screws. Also use three
equidistant metal screws to attach the connector to the stove’s exhaust collar. See
Figure 2.3 (A) and Figure 2.3 (B).
The pipe must be short and straight. All sections installed horizontally must slope
at least ¼ inch per foot, with the upper end of the section toward the chimney. See
Figure 2.3 Detail B.
To insure a good draft, the total horizontal length of the connector should never
exceed 8' to 10' (2.4 to 3.04 m). In the case of vertical installation, the total length
of the connector can be much longer and connected without problem to the
chimney at the ceiling level.

15
There should never be more than two 90 degrees elbows in the whole connector
and chimney system. Never start with a 90oelbow. Always go up vertically for at
least 2 feet from the flue spigot before using a 90oelbow.
The connector must not pass through any combustible material, nor may it pass
through a concealed space (such as an attic, roof space, or closet). If passing
through a wall, ceiling, or into a masonry chimney, use either chimney components
listed for that specific use, or means acceptable to local authorities having
jurisdiction over the installation.
Installation of a "barometric draft stabiliser" (fireplace register) on a connector is not
recommended.
FIGURE 2.3 (A) Connecting Sections
FIGURE 2.3 (B) Minimum Slope
The assembly should be as short and direct as possible between the stove and
chimney (See figure 2.4 (A)). The use of two 45 degree elbows (See figure 2.4 (C))
is often preferable to a single 90 degree elbow (See figure 2.4 (B)) because less
turbulence is created in the exhaust flow and they result in less horizontal run.

DRAFT
Your E.P.A Drolet stove’s performance will be optimised if it is installed with a chimney
(flue) system that provides an adequate draft. The draft is the force that moves air from
the appliance up through the chimney and is predominantly affected by the height and
diameter of the chimney, as well as the stack temperatures of the stove. If you test the
draft using a pressure gauge, the reading should be between .05 - .07 inches of water
column (w.c.) at a medium-high fire. A draft measure of less than .03" w.c. will cause
operational difficulties while too much draft (greater than .10" w.c.) will result in over-firing
of the stove. This can result in excessive operating temperatures. In this case, the
installation of elbows totaling no more than 180° (ex.: 2 x 30° elbows, 2 x 45° elbows or 2
x 90° elbows) can be installed to help reduce excessive draft. If the addition of elbows is
not sufficient, a manual damper can be installed in the vertical flue pipe.

Data provided by Energy, Mines and Resources - Canada
IT IS EXTREMELY IMPORTANT THAT YOU USE DRY WOOD ONLY IN YOUR WOOD
STOVE. The wood must have dried for 9 to 15 months, such that the humidity content (in
weight) is reduced below 20% of the weight of the log. It is very important to keep in mind
that even if the wood has been cut since one, two or even more years, it is not necessarily
dry, if it has been stored in poor conditions; under extreme conditions, it may even rot
instead of drying. The vast majority of the problems related to the operation of a wood
stove are caused by the fact that the wood used was too damp or had dried in poor
conditions. These problems can be:
ignition problems
creosote build-up causing chimney fires
low energy yield
blackened windows
incomplete log combustion
