The DROLET Woodstove Manual
DROLET STOVES AND FIREPLACES INC. one of the most important woodstove and
fireplace manufacturers in Canada, congratulates you on your purchase and wishes to
help you get maximum satisfaction from the woodstove you have selected. In the pages
that follow, we will give you advice on wood heating and controlled combustion as well as
technical specifications regarding installation, operation and maintenance of the model
you have chosen.
The instructions pertaining to the installation of your woodstove comply with ULC S627
standards. You must follow them very carefully in order to eliminate any chance of
encountering major problems.
KEEP THIS INSTRUCTION MANUAL SINCE IT MAY BE VERY HELPFUL.
Wood Heating
Many consumers choose wood as the main or auxiliary energy source for heating their
main home or secondary residence. This source of energy has the advantage of being
abundant, relatively cheap and easy to store so that you are assured of energy autonomy
for more of less longer periods.
The Controlled Combustion
The main feature of a controlled combustion woodstove is an air tightness that is the most
perfect possible, and must of course be equipped with the most efficient heat exchanger
possible in order to transfer maximum heat to the ambient air. It is generally doubled with
firebricks, and it may have a glass door, with steel or cast iron frame. The main feature
that makes it a controlled combustion woodstove remains its air tightness, which allows
the user to control the quantity of oxygen admitted into the woodstove.
The wood will burn slowly if the woodstove draught keys are adjusted in order to reduce
the oxygen supply in the combustion chamber to minimum; on the other hand, wood will
burn quickly if the draught keys are adjusted to admit a larger quantity of oxygen in the
combustion chamber.

Installation Of Your Drolet Woodstove
Positioning The Stove
It is very important to position the woodstove as close as possible to the chimney, and in
an area that will favor the most efficient heat distribution possible throughout the house.
The stove must therefore be installed in the room where the most time is spent, and in the
most spacious room possible. Remember: woodstoves produce radiating heat, the heat
we feel when we are close to a woodstove. A woodstove also functions by convection,
that is through the displacement of hot air accelerated upwards and its replacement with
cooler air. If necessary, the hot air distribution from the stove may be facilitated by a
blower or the installation of floor or wall grills.
Important: A woodstove must never be installed in a hallway or near a staircase,
since it may block the way in case of fire or fail to respect required
clearance.
The woodstove must not be hooked up to a hot air distribution system
since an excessive accumulation of heat may occur.
Floor Protection
Your woodstove should be placed on a non-combustible surface. Having these minimum
specifications.

1/4" (6 mm) 18" (457 mm) 6" (150 mm) 6" (150 mm)
Clearances
It is of outmost importance that the clearances to combustible material mentioned on your
woodstove certification plate be scrupulously respected upon installation.

16" (406 mm) 16" (406 mm) 16" (406 mm) 7' (2,3 m)
* Height, from bottom of the stove to the ceiling.

You may decrease these 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.
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.

This reduction in clearance, when in compliance, is accepted by insurance companies.

Chimney
Your woodstove may be hooked up with a prefabricated or masonry chimney. If you are
using a prefab chimney, it must comply with ULC S629 standards; therefore it must be of
the 2100 °F / 650 °C. (2" / 51 mm thick insulated type). It is extremely important to install
the chimney 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 firebricks, 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 that of the stove smoke
exhaust. A flue which is too small may cause draught problems, while a large flue favors
rapid cooling of the gas, and hence the build-up or creosote and the risk of chimney fires.
Current practice requires that the diameter of the chimney flue does not exceed the stove
exhaust one by more than 30-35%. Note that it is the chimney and not the stove that
creates the draught effect. Your stove's performance is directly dependent on an
adequate draught from your chimney.
The following recommendations may be useful for the installation of your chimney:
1) It must rise above the roof at least 3' (0,9 m) from the uppermost point of contact.
2) The chimney must exceed any part of the building or other obstruction within a 10'
(3,04 m) distance by a height of 2' (0,60 m).
3) 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 gases which circulate will cool more
slowly thus reducing the build-up of creosote and the risk of chimney fires.
4) The draught causes by the tendency for hot air to rise will be better with an interior
chimney.
5) You must not install more than one heating unit per chimney flue.
6) Use of 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

Couplings
Once the woodstove is placed in the room in accordance with required clearances,
it must be coupled to the chimney with a smoke exhaust system. Verify the
clearance between your stovepipe and the surrounding combustible surfaces. If
the normal 18-inch (457 mm) clearance required cannot be obtained, you may use
an insulated flue pipe or a thermal protection shield. Read and respect
manufacturer's instructions before installation.
Coupling pipes and chimney
must have the same diameter as
the stove outlet. If this is not the
case, contact your supplier in
order to insure there will be no
problem with the draught. Pipes
should be made of aluminized or
ordinary steel with a minimum 24
gauge thickness.
Your smoke evacuation system (pipes) should be assembled in such a way that
the male section of the pipes faces down. Attach each of the sections to one
another with three equidistant metal screws. The pipes must be short and straight.
A
ll sections installed horizontally must slope at least 1/4 inch per foot, with the
lower section toward the stove.
To insure a good draught, the total length of the coupling pipe should never exceed 10
feet (3.04 m). (Except for cases of vertical installation, (cathedral-roof style) where the
smoke exhaust system can be much longer and connected without problem to the
chimney of the ceiling of the room). There should never be more than one 90°elbow in
the smoke exhaust system.
Installation of a "barometric draught stabilizer" (fireplace register) on a smoke exhaust
system is prohibited. Furthermore, installation of a draught damper is not recommended.
Indeed, with a controlled combustion woodstove, the draught is regulated upon intake of
the combustion air in the stove and not at the exhaust.
The connecting pipe must not go through ceiling, storage area, floor or any other
combustible partition.
8

Air Circulation Systems
In order to improve air circulation in the room where the woodstove is installed, certain
options are available for specific stove models.
Blower: A variable speed-control blower with a capacity of 100 CFM (2.83
m3/min) is available.
Thermodisc: The thermodisc is installed on the blower's electrical supply cord, and it
will start the blower when the stove temperature reaches 120°F (49oC)
and cut off the power when the stove cools below 100°F (37oC).
Information regarding installation of the thermodisc is included with the
device.
Operating Your Drolet Woodstove
Solid Fuel
Your heating unit is designed to burn wood only; no other materials should be burned.
Wastes and other flammable materials should not be burned in your woodstove. Any
type of wood may be used in your stove, but specific varieties have better energy yields
than others. Please consult the following table in order to make the best possible choice.

It is EXTREMELY IMPORTANT that you use DRY WOOD only in your woodstove. 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 for 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. This point cannot be overstressed; the vast majority of the problems related to the
operation of a woodstove is 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.
Smaller pieces of wood will dry faster. All logs exceeding 6" (152 mm) should be split.
The wood should be stored in a place where the grass is not too long, in such a way that
prevailing winds may circulate through the fire logs. A 24" to 48" (610 mm to 1219 mm)
air space should be left between each row of fire logs, which should be placed in the
sunniest location possible. If the wood must be stored outside, the upper layer of wood
should be protected from rain and bad weather but not the sides.
Before your first burn
• Check if firebricks are lined properly.
• If necessary, take off plastic protector from moldings.
• Make sure that the chimney and flue pipe are well installed according to
specifications.
• Respect all clearances to combustibles and floor protection according to the unit you
have chosen.
• If your not sure about the proper installation, do not hesitate to contact your Drolet
dealer.
10

Ignition
The installation of a log cradle is NOT RECOMMENDED in your DROLET woodstove.
After making sure that the stove air intake controls are fully open, place several rumpled
sheets of paper in the center of the combustion chamber. Place 8 to 10 pieces of small
dry kindling wood over the paper in the form of a tent. You may also place a few pieces
of heating wood, but choose them as little as possible. No chemical product (or
accelerant) should be used to light the fire.
Before igniting the paper and kindling wood, it is recommended that you warm up the
chimney. This is done in order to avoid back draft problems often due to negative
pressure in the house; cold air from the outside tends to penetrate into the house by the
chimney.
If such is the case, open slightly a window near the stove and twist together a few sheets
of newspaper into a torch. Light up this paper torch and hold it as close as possible to the
mouth of the pipe inside the combustion chamber to warm up the chimney. Once the
updraft movement is initiated, you are ready to ignite the stove by lighting the paper and
kindling wood inside the combustion chamber.
We therefore advise you to leave the door slightly opened (a few inches) for a 5 to 10
minute period, under supervision, in order to allow for good combustion. After this time,
you may close the door and progressively adjust the air controls to obtain the desired
temperature. In the case of knobbed air controls, they may be closed by bringing them
towards the stove. The slide controls (left-right push-pull) are closed when pushed to the
left or pushed towards the back depending on the model.
CAUTION:
• Do not leave the stove unattended when the door is slightly opened.
• When the stove is used for the first time, intense fire is prohibited in order to allow
adequate cooking of the paint covering the stove and to prevent a "thermal shock"
which may remove or whiten the paint.
• Make sure the room is well ventilated, to remove the bad odors emitted from the paint,
during the first, two or three hours of using the stove and for the first three or four fire
start-ups.
• Never heat the stove outside the house, before installation: it is then impossible to
adequately monitor the combustion intensity, which provokes overheating and a
thermal shock to the paint.
• Never use fluid or chemical products to ignite the fire.
• Do not burn wastes, flammable fluid such as gasoline, naphtha or motor oil.
11

Heating
Once you have obtained a good bed of embers you should reload the unit. In order to do
so, open the air controls to maximum a few seconds prior to opening the stove door.
Then proceed by opening the door very slowly; open it one or two inches for 5 to 10
seconds, before opening it completely to increase the draught and thus eliminate the
smoke which is stagnant in a state of slow combustion in the stove. Then bring the red
embers to the front of the stove and reload the unit. Use only the quantity of wood
required depending on the circumstances; for example, in severe cold load the stove to
maximum, in milder temperatures the stove should be only half loaded.
For optimal operation of your woodstove, we recommend you operate it with a wood load
approximately equivalent to the height of fire bricks (this should be the maximum height of
wood lead).
The combustion air supply control is located above the door. The air intake is opened
when the control knob is completely on the left side and closed when it is pushed towards
the right.
It is extremely important that you use your stove in such a way that you do not lower the
temperature of the combustion gases inside the chimney too much. For this purpose, we
strongly recommend that you install a magnetic thermometer on your smoke exhaust
pipe, approximately 18" (457 mm) above the stove. This thermometer will indicate the
temperature of your gas exhaust fumes within the smoke exhaust system. The ideal
temperature for these gases is somewhere between 275°F and 500°F (135 °C and 260
°C). Below this temperature, the build-up of creosote is promoted while above 500 °F
(260 °C) , heat is wasted since too large a quantity is emitted into the atmosphere.
In summary, it is very easy to operate your controlled combustion woodstove, and you
can prevent all potential problems by taking this advice:
1. Select a stove of adequate size: selecting a stove that is too big for the area to be
heated is a common mistake.
2. Follow the installation standards scrupulously and respect the combustible material
clearances for the stove, coupling pipes and the chimney.
3. Burn only dried wood, that is, with a maximum 20% humidity content; this is the most
important recommendation of all.
4. Install a magnetic thermometer on your pipe, 18" (457 mm) above the stove, and
maintain the temperature of your exhaust gas fumes between 275 °F and 500°F (135
°C and 260 °C).
12

Keep in mind that the most difficult months for wood heating are October and November.
Indeed, during this period, the atmosphere is often very heavy and humid, and may hinder
chimney draught. Moreover, the wood is often too damp, since it has not had a sufficient
drying period, or it has been stored outside in the rain. Combustion problems may then occur;
they are caused neither by the stove nor the chimney, but by outside factors, and will resolve
themselves as the season progresses.
IMPORTANT:
It is important to note that wood combustion consumes ambient oxygen in the room. In the
case of negative pressure, it is a good idea to allow for a fresh air intake in the room, either by
opening a window slightly or by installing a fresh air intake system in an outside wall.
Maintenance Of The Heating System
Maintenance Of The Woodstove
Slow combustion stoves are designed so that they require little maintenance:
• It is wise to perform a visual inspection of the stove approximately once a month, in order
to insure that no parts have been damaged, in which case repairs must be performed
without delay.
• It is recommend that you change the fiber ceramic seal (which makes the seal on your
stove door airtight) once a year, in order to insure good control over the combustion,
maximum efficiency and security. To change your airtight seal, simply remove the
damaged seal, carefully clean the available surface, apply a special glue sold for this
purpose, and spread the new airtight seal. You may light up your stove again
approximately two hours after having completed this operation.
• You should regularly dispose of the ashes, as soon as they prevent your from placing a
normal load of fire logs. We recommend always leaving 1’’ (25.4 mm) of ashes in the
bottom of the stove in order to insure maximum efficiency.
• Always use a metal container with a lid to save the cooled ashes you remove from the
stove. Make sure that there are no live embers. Moreover, it is wise to place the metal
container on an insulated surface.
• It is possible to give your woodstove a brand new look, by repainting it with a 1200 oF (649
oC) heat resistant paint. For this purpose, simply rub the surface to be repainted with fine
sand paper, clean it properly, and apply thin coats of paint successively. Remember the
advice that was given regarding new paint upon ignition of the stove because it again
applies.
13

Maintenance Of The Chimney
Whether you have a prefab or masonry chimney, you must conduct a visual
inspection at least once a month in order to be sure that it is in good shape and
that there is no excessive creosote build-up. If there is the slightest crack, or
undulation of the interior or exterior surface of the chimney, repairs or
replacements of defective parts must be carried out without delay.
You should do at least one chimney sweeping per year, or more if your visual
inspection reveals creosote deposits exceeding 1\4" (6 mm). It is important to
remove all creosote, which has been detached with the sweeping brush, in order
to prevent if from igniting.
