WARNING:
DO NOT INSTALL A MANUAL DAMPER ON THIS FURNACE.
CAUTION: BEFORE THE CONNECTOR PIPES ARE INSTALLED, MAKE SURE THAT
THE EXHAUST PIPE AND / OR THE EXCHANGERS OF THE FURNACE ARE FREE OF
ALL ITEMS.
4.1 The chimney
- The furnace must be connected to a factory-built metal chimney that complies with UL
103 HT (USA) or ULC S629 (Canada).
o Strongly recommended inner diameter: 6" (152 mm).
o A chimney having a diameter of more than 7" (178 mm) is permitted, if it allows
the proper venting of combustion gases and that such application is verified and
authorized by a qualified installer. Otherwise, the diameter of the flue must be
reduced to 6" (152 mm) by the use of a stainless steel liner made for this
purpose.
4.1.1 Factory-built metal chimneys
To be suitable, a factory-built metal chimney also called “high temp” chimney, must comply
with UL 103 HT (U.S.A.) or ULC S629 (Canada).
- Use only components intended for the
brand and model of the chimney you
are using.
- Never substitute parts from other
chimney brands.
- Never fabricate your own components.
- The chimney must be a type suitable
for solid fuel.
- To be safe and effective, the chimney
must be installed exactly in accordance
with the manufacturer’s instructions.
13
HeatPro Furnace Installation and Operation Manual
Good system design
Inferior system design
Inside chimneys are preferred because
even when no fire is burning, there is
normally upward flow in the system.
Outside chimneys are a problem because
when no fire burns they will go into cold
backdraft if the furnace is installed low in the
house.
4.1.2 Masonry chimneys
The furnace may also be connected to a masonry chimney, provided the chimney
complies with the construction rules found in the building code enforced locally.
- The chimney must have a clay liner.
- If the masonry chimney has a
square or rectangular liner that is
larger in cross-sectional area than a
round 6" (152 mm) flue, it should
be relined with a suitably listed
6" (152 mm) stainless steel liner.
- When passing through a
combustible wall, the use of an
insulated listed thimble is required.
- If a stainless steel jacket (liner) is to
be installed, it must extend
12" (305 mm) to 18" (457 mm)
above the top of the masonry
chimney to favor the draw.
14
HeatPro Furnace Installation and Operation Manual
4.1.3 Minimum chimney height
The top of the chimney should be tall enough to be above the air turbulence caused when
wind blows against the house and its roof.
- The chimney
must extend at
least 3 ft. (1 m)
above the
highest point of
contact with the
roof.
- Extend at least
2 ft. (61 cm)
higher than any
roof line or
obstacle within a
horizontal
distance of 10 ft.
(3 m).
4.2 The connector pipe
Recommended inner diameter : 6" (152 mm).
If an increaser/reducer must be used (max 6" (152 mm) to 7" (178 mm)), it must
be installed as close as possible the chimney.
4.2.1
Best practices and requisites of the installation code
o Where passage through a wall or partition of combustible construction is
desired, the installation shall conform to CAN/CSA-B365, Installation Code for
Solid-Fuel-Burning Appliances and Equipment;
o A flue pipe must never pass through a combustible floor or ceiling or through an
attic, roof space, closet or concealed space;
o Minimum upward slope towards the chimney: 1/4 in/ft. (20 mm/m);
o The maximum horizontal run is 10’ (3 m). Do not count the starting elbow;
o All flue pipe joints must be secured with three screws. Failure to secure them to
each other may cause a fire;
15
HeatPro Furnace Installation and Operation Manual
Proper installation
improper installation
CAUSES
RESTRICTION
o Maximum unsupported horizontal length: 3 feet (1 m);
o Galvanized flue pipes must not be used because the coatings vaporize at high
temperatures and release dangerous gases;
o Flue pipes must be at least 24 gauge in thickness;
o The chimney connector must be in good condition;
o Flue pipe joints should overlap 1 1/4" (30 mm);
o Straight up installations need to have either a connector where one end has no
fastener or a telescopic length;
o Removal of the assembly for cleaning should not require that the furnace be
moved;
o The male ends of the sections must be oriented towards the appliance so that
falling dust and condensation stay inside the pipe;
o A straight flue pipe assembly offers the least restriction to gas flow and results in
stronger draft. Straight assemblies also need less maintenance because there
are no corners to collect creosote;
o The use of 45° elbows is strongly recommended;
o A 90° elbow = 5’ (152 cm), a 45° elbow = 2.5’ (76 cm);
o Never use more than two 90° elbows.
16
HeatPro Furnace Installation and Operation Manual
Use 45° elbows where possible, rather than 90° elbows.
Alternative installations with 90° elbow or tee.
5 Hot air distribution and air return system
The Drolet furnace is designed and equipped with a hot air distribution plenum that may
receive 6 to 10, 6" (152 mm) diameter round ducts.
The installer is responsible for the performance of the distribution ducts and the air
return system. It will have a direct effect on the ability of the blower to distribute
heat efficiently throughout the house. The number, size and length of the ducts of
the distribution system and return air will vary depending on the configuration and
characteristics of each house.

than 84" (213 cm), it will be possible to cut
the plenum extension (A) of at most
10" (254 mm). The plenum extension (A)
must therefore have a minimum height of
14'' (356 mm).
Warning: The plenum extension (A) should
not obstruct the openings for the hot air
distribution of the plenum (B). The shaded
area represents the maximum cutting of
plenum extension (A).

- The maximum run of a secondary duct is 10’ (3 m).
- The maximum length of all the secondary ducts is 100’ (30 m).
- The finishing grill at the output of a secondary pipe must be made of metal.
The total area of secondary duct outlets must be equal or slightly less than the total area of
the outlets used on the distribution plenum (B).

ACCORDING TO THE NATIONAL BUILDING CODE, THE BTU/H PROVIDED BY AN
OUTLET ON THE PLENUM MUST NOT EXCEED 10,250 BTU/H (3kW) AND THE HOT
AIR TEMPERATURE AT THE OUTLET OF A SECONDARY DUCT SHOULD NOT
EXCEED 158 °F (70 °C).
Once your hot air distribution system is installed, make sure to measure the static pressure
in the start-off plenum. Adjust the opening at the end of each of distribution duct with a
shutter until you get a static pressure 0.2" W.C. (50 Pa) at the plenum.
The default blower speeds can be changed depending on the restriction created by the
configuration of your distribution system (see Section 7.3: Blower technical Data).
5.5 Air return system and filter
The installation of an optional air return duct connected to the blower housing will improve
the air circulation throughout the house (see Appendix 3: Optional Fresh air return
adapter (AC01392)). The use of the air filter option is also recommended. The filter
option will significantly reduce dust circulation within the hot air duct and will prevent
obstruction of the blower (see Appendix 2: Optional air filters (AC01390, AC01391)).

This leads to premature wear of the furnace, a situation that is not covered by warranty.
o A draw greater than -0.08" W.C. (20 Pa) leads to uncontrollable fire even if the
air control is in closed position.
o To prevent excessive draft, a barometric control must be installed to control
excessive draft. It must be adjusted to the maximum draft of 0.06" W.C. (15 Pa)
measured at the output of the furnace.

7.4.1 The use of a thermometer
The first use of a thermometer is to inform the user about the discharge temperature of flue
gases. Without accurate measurement of the draft using a pressure gauge (manometer),
the thermometer will indicate if the temperature is ideal, too low or too high.
The use of e thermometer is therefore an acceptable alternative that can tell if the chimney
is hot enough to generate an adequate draft.
- Use a magnetic thermometer for Single wall connector pipe.
- Use a probe thermometer for Double wall connector pipe.

Appendix 1: Optional thermostat installation
Using a thermostat will help you maintain a constant temperature throughout the house. A
fixed wall mounted 24v thermostat is required.
Note: Thermostat manufacturer’s instruction always overrides the information
published in the following section.
Thermostat location
- Must be installed on an inside wall of the
house.
- Where it will be the least affected by
affected by air currents from a hot air
outlet or cold outside walls.
- Must be installed at a minimum of
55" (140 cm) above the floor.
- Must be installed at a minimum of
15’ (4.57 m) from the furnace and must
not receive radiation from the glass
door.
Thermostat wiring
Before installing the thermostat, disconnect
the furnace from the outlet.
Use an 18 AWG 2 strand wire.
The terminal is located at the back on the
rear right side of the furnace when facing it.
It is marked with the letter “T”.
Loosen the two screws in the middle of the
terminal bloc and insert the wires in the
terminals. Tighten the two screws.
Open the thermostat housing and connect
the wires following the manufacturer's
instructions.
35
HeatPro Furnace Installation and Operation Manual
Example of thermostat wiring:
Connect one wire to "HR" and
the other wire to "W". The red
jumper can be left in place. For
more information, refer to the
manufacturer's instructions.
This furnace may be installed in
parallel as an add-on to an
existing furnace in the USA only.
Such an installation requires that
the furnace’s controls be
interlocked to prevent both
furnaces from heating at
maximum rate simultaneously.
In order to interlock the furnaces,
connect the wires from the
existing furnace’s thermostat,
normally R and W, to the terminal
identified “INTERLOCK” located
next to the thermostat terminal of
the HeatPro.
When the wood furnace receives
the signal from the existing
furnace’s thermostat calling for
heat, it will disconnect the
damper motor, sending the wood
furnace in low burn until the call
for heat from that thermostat is
satisfied.
After the existing furnace’s
thermostat is satisfied, the wood
furnace will return under the
control of its own thermostat.
Use in thermostat mode
To ensure the proper operation of the air inlet damper while connected to a thermostat, the
manual control switch must be maintained in the closed position. However, when a
thermostat is connected to the furnace, it is still possible to use the manual control switch
to open the air damper if desired. Even though you chose to control the furnace with a
thermostat it is still possible to use the manual control switch to open the air intake damper
if desired.

7.5 How to prepare or buy good firewood
7.5.1 What is good firewood?
Good firewood has been cut to the correct length for the furnace, split to a range of sizes
and stacked in the open until its moisture content is reduced to 15 to 20 per cent.
7.5.2 Tree species
The tree species the firewood is produced from is less important than its moisture content.
The main difference in firewood from various tree species is the density of the wood.
Hardwoods are denser than softwoods. People who live in the coldest regions of North
America usually have only spruce, birch and poplar, other low-density species to burn and
yet they can heat their homes successfully.
Homeowners with access to both hardwood and softwood fuel sometimes use both types
for different purposes. For example, softer woods make good fuel for relatively mild
weather in spring and fall because they light quickly and produce less heat Softwoods are
not as dense as hardwoods so a given volume of wood contains less energy. Using
softwoods avoids overheating the house, which can be a common problem with wood
heating in moderate weather. Harder woods are best for colder winter weather when more
heat and longer burn cycles are desirable.
Note that hardwood trees like oak, maple, ash and beech are slower growing and longer
lived than softer woods like poplar and birch. That makes hardwood trees more valuable.
The advice that only hardwoods are good to burn is outdated. Old, leaky cast iron furnaces
wouldn’t hold a fire overnight unless they were fed large pieces of hardwood. That is no
longer true. You can successfully heat your home by using the less desirable tree species
and give the forest a break at the same time.
7.5.3 Log length
Logs should be cut about 1" (25 mm) shorter than the
firebox so they fit in easily. Pieces that are too long
makes loading the furnace very difficult. The most
common standard length of firewood is 16" (406 mm).
The pieces should be a consistent length, with a
maximum of 1" (25 mm) variation from piece to piece.
39
HeatPro Furnace Installation and Operation Manual
7.5.4 Piece size
Firewood dries more quickly when it is split. Large unsplit rounds can take years to dry
enough to burn. Even when dried, unsplit logs are difficult to ignite because they don’t
have the sharp edges where the flames first catch. Logs as small as 3" (76 mm) should be
split to encourage drying.
Wood should be split to a range of sizes, from about 3" to 6" (76 mm to 152 mm) in cross
section. Having a range of sizes makes starting and rekindling fires much easier. Often,
the firewood purchased from commercial suppliers is not split finely enough for convenient
stoking. It is sometimes advisable to resplit the wood before stacking to dry.
7.5.5 How to dry firewood
Firewood that is not dry enough to burn is the cause of most complaints about wood
inserts. Continually burning green or unseasoned wood produces more creosote and
involves lack of heat and a dirty glass door. See Section 9: Maintaining your wood
heating system for concerns about creosote.
Here are some things to consider in estimating drying time:
•
firewood takes a long time to dry
•
firewood bought from a dealer is rarely dry enough to burn, so it is advisable to buy the
wood in spring and dry it yourself
•
drying happens faster in dry weather than in damp, maritime climates
•
drying happens faster in warm summer weather than in winter weather
•
small pieces dry more quickly than large pieces
•
split pieces dry more quickly than unsplit rounds
40
HeatPro Furnace Installation and Operation Manual
•
softwoods take less time to dry than hardwood
•
softwoods like pine, spruce, and poplar/aspen can be dry enough to burn after being
stacked in the open for only the summer months
•
hardwoods like oak, maple and ash can take one, or even two years to dry fully,
especially if the pieces are big
•
firewood dries more quickly when stacked in the open where it is exposed to sun and
wind; it takes much longer to dry when stacked in a wood shed
•
firewood that is ready to burn has a moisture content between 15 and 20% by weight
and will allow your furnace to produce its highest possible efficiency
7.5.6 Judging firewood moisture content
You can find out if some firewood is dry enough to burn by using these guidelines:
•
cracks form at the ends of logs as they dry
•
as it dries in the sun, the wood turns from white or cream coloured to grey or yellow,
•
bang two pieces of wood together; seasoned wood sounds hollow and wet wood
sounds dull,
•
dry wood is much lighter in weight than wet wood,
•
split a piece, and if the fresh face feels warm and dry it is dry enough to burn; if it feels
damp, it is too wet,
•
burn a piece; wet wood hisses and sizzles in the fire and dry wood does not.
You could buy a wood moisture meter to test your
firewood.
8 Operating your furnace
8.1 Your first fires
Two things will happen as you burn your first few fires; the paint cures and the internal
components of the furnace are conditioned.
As the paint cures, some of the chemicals vaporize. The vapours are not poisonous, but
they do smell bad. Fresh paint fumes can also cause false alarms in smoke detectors. So,
when you first light your furnace, be prepared by opening doors and/or windows to
ventilate the house. As you burn hotter and hotter fires, more of the painted surfaces reach
the curing temperature of the paint. The smell of curing paint does not disappear until you
have burned one or two very hot fires.
It is recommended to burn it at high rate and ventilate the building until the odours
disappear. Once the paint smell disappears, your furnace is ready for serious heating.
41
HeatPro Furnace Installation and Operation Manual
8.2 Lighting fires
Each person who heats with wood develops their own favourite method to light fires.
Whatever method you choose, your goal should be to get a hot fire burning quickly. A fire
that starts fast produces less smoke and deposits less creosote in the chimney. Here are
three popular and effective ways to start wood fires.
8.2.1 Conventional fire starting
The conventional way to build a wood fire is to
bunch up 5 to 10 sheets of plain newspaper and
place them in the firebox. Next, place 10 or so
pieces of fine kindling on the newspaper. This
kindling should be very thin; less than 1" (25 mm).
Next, place some larger kindling pieces on the fine
kindling. Open the air control and light the
newspaper. If you have a tall, straight venting
system you should be able to close the door
immediately and the fire will ignite. If your venting
system has elbows or an outside chimney, you
may need to leave the door closed but unlatched
for a few minutes as the newspaper ignites and
heat in the chimney produces some draft. Once
the fire has ignited, close the door and leave the
air control open.
A conventional kindling fire with
paper under finely split wood.
DO NOT LEAVE THE FURNACE UNATTENDED WHEN THE DOOR IS SLIGHTLY
OPEN DURING IGNITION. ALWAYS CLOSE THE DOOR AFTER IGNITION.
After the kindling fire has mostly burned, you can add firewood pieces until you have a fire
of the right size for the conditions.
8.2.2 The top down fire
The top down fire starting method solves two problems with the conventional method: first,
it does not collapse and smother itself as it burns; and second, it is not necessary to build
up the fire gradually because the firebox is loaded before the fire is lit. A top down fire can
provide up to two hours of heating or more. The top down method only works properly if
the wood is well-seasoned.
Start by placing three or four full-sized split pieces of dry firewood in the firebox. Next,
place 4 or 5 more finely split pieces of firewood (2" to 3" (51 mm to 76 mm) diameter) on
the base logs at right angles (log cabin style). Now place about 10 pieces of finely split
kindling on the second layer at right angles.
The fire is topped with about 5 sheets of newspaper. You can just bunch them up and stuff
them in between the kindling and the underside of the baffle. Or you can make newspaper
knots by rolling up single sheets corner to corner and tying a knot in them. The advantage
of knots is that they don’t roll off the fire as they burn. Light the newspaper and watch as
the fire burns from top to bottom.
42
HeatPro Furnace Installation and Operation Manual
8.2.3 Two parallel logs
Place two spit logs in the firebox. Place a few sheets of twisted newspaper between the
logs. Now place some fine kindling across the two logs and some larger kindling across
those, log cabin style. Light the newspaper.
8.2.4 Using fire starters
Many people like to use commercial fire starters instead of newspaper. Some of these
starters are made of sawdust and wax and others are specialized flammable solid
chemicals. Follow the package directions for use.
Gel starter may be used but only if there are no hot embers present. Use only in a cold
firebox to start a fire.
8.3 Maintaining wood fires
8.3.1 General advice
Wood heating is very different than other forms of heating.
Do not expect steady heat output from your furnace. It is normal for its temperature to rise
after a new load of wood is ignited and for its temperature to gradually decline as the fire
progresses. This rising and falling of temperature can be matched to your household
routines. For example, the area temperature can be cooler when you are active, such as
when doing housework or cooking, and it can be warmer when you are inactive, such as
when reading or watching television.
Wood burns best in cycles. A cycle starts when a new load of wood is ignited by hot coals
and ends when that load has been consumed down to a bed of charcoal about the same
size as it was when the wood was loaded. Do not attempt to produce a steady heat output
by placing a single log on the fire at regular intervals. Always place at least three, and
preferably more, pieces on the fire at a time so that the heat radiated from one piece helps
to ignite the pieces next to it. Each load of wood should provide several hours of heating.
The size of each load can be matched to the amount of heat needed.
When you burn in cycles, you rarely need to open the furnace’s loading door while the
wood is burning. This is an advantage because there is more chance that smoke will leak
from the furnace when the door is opened as a full fire is burning. This is especially true if
the chimney connector has 90 degree elbows and if the chimney runs up the outside wall
of the house.
IF YOU MUST OPEN THE DOOR WHILE THE FUEL IS FLAMING, OPEN THE AIR
CONTROL FULLY FOR A FEW MINUTES, THEN UNLATCH AND OPEN THE DOOR
SLOWLY.
IMPORTANT
WHEN RELOADING, MAKE SURE YOU KEEP THE AIR INLETS LOCATED AT THE
BOTTOM OF THE DOOR INSIDE THE COMBUSTION CHAMBER FREE OF ASH.
OPENING PROCEDURE FOR THE LOADING DOOR
TO MINIMISE THE RISK OF SMOKE SPILLAGE, CRACK THE DOOR OPEN ABOUT
AN INCH (25 MM) AND WAIT ABOUT 10 SECONDS BEFORE OPENING IT WIDE TO
ALLOW STABILISATION OF THE PRESSURE INSIDE THE FURNACE.
43
HeatPro Furnace Installation and Operation Manual
8.3.2 Raking charcoal
Rekindle the fire when you notice that the room temperature has fallen. Do not operate
your furnace at too low a setting. Keep the air inlet opened long enough during the fire
start-up to prevent the fire from smouldering, which could stain the glass. You will find
most of the remaining charcoal at the back of the firebox, furthest from the door. Rake
these coals towards the door before loading. There are two reasons for this raking of the
coals. First, it concentrates them near where most of the combustion air enters the firebox
and where they can ignite the new load quickly, and second, the charcoal will not be
smothered by the new load of wood. If you were to simply spread the charcoal out, the
new load will smoulder for a long time before igniting.
Remove ash first, and then rake charcoal towards the front of the firebox before loading so
that it will ignite the new load.
8.3.3 Firing each new hot load
Place the new load of wood on and behind the charcoal, and not too close to the glass.
Close the door and open the air control fully. Leave the air control fully open until the
firebox is full of flames, the wood has charred to black and its edges are glowing red. Firing
each load of wood hot accomplishes a few things:
•
drives the surface moisture from the wood,
•
creates a layer of char on the wood, which slows down its release of smoke,
•
heats the firebox components so they reflect heat back to the fire, and
•
heat the chimney so it can produce strong, steady draft for the rest of the cycle.
DO NOT LEAVE THE FURNACE UNATTENDED WHILE A NEW LOAD IS BEING
FIRED HOT.
DO NOT OVERFIRE.
When you burn a new load of wood hot to heat up the wood, the furnace and the chimney,
the result will be a surge of heat from the furnace. This heat surge is welcome when the
room temperature is a little lower than desirable, but not welcome if the space is already
warm. Therefore, allow each load of wood to burn down so that the space begins to cool
off a little before loading.
44
HeatPro Furnace Installation and Operation Manual
8.3.4 Control of the air supply
Once the firewood, firebox and chimney are hot, you can close the air supply for a steady
burn.
If the flames get very small and almost disappear when you close the air, you have closed
the air too early, or your firewood is wetter than it should be. With good fuel and correct air
control use, the flames should slow down, but should stay large and steady, even as the
air supply is closed.
When the furnace is using a thermostat, it is the thermostat that controls the air inlet
damper. When the thermostat calls for heat, the damper opens and the combustion is
stirred up. When the furnace gets hot enough, the blower motor is activated.
The following figure shows the position of the air inlet damper (A) according to the position
of the air inlet damper switch (B).
45
HeatPro Furnace Installation and Operation Manual
8.3.5 Building different fires for different needs
Using the air control is not the only way to match the furnace’s heat output to the heat
demand. Your house will need far less heat in October than in January to be kept at a
comfortable temperature. If you fill the firebox full in fall weather, you will either overheat
the space or turn the furnace down so much that the fire will be smoky and inefficient. Here
are some suggestions for building fires to match different heat demand.
8.3.5.1 Small fires to take the chill off the house
To build a small fire that will produce a low heat output, use small pieces of firewood and
load them crisscross in the firebox. The pieces should be only 3” (76 mm) to 4” (102 mm)
in diameter. After raking the coals, you can lay two pieces parallel to each other corner to
corner in the firebox and lay two more across them in the other direction. Open the air
control fully and only reduce the air after the wood is fully flaming. This kind of fire is good
for mild weather when you are around to tend the furnace and should provide enough heat
for four hours or more. Small fires like this are a good time to use softer wood species so
there will be less chance of overheating the house.
8.3.5.2 Long lasting low output fires
Sometimes you will want to build a fire to last up to eight hours, but don’t need intense
heat. In this case use soft wood species and place the logs compactly in the firebox so the
pieces are packed tightly together. You will need to fire the load hot for long enough to fully
char the log surfaces before you can turn the air down. Make sure the fire is flaming
brightly before leaving the fire to burn.
8.3.5.3 High output fires for cold weather
When the heat demand is high during cold weather, you’ll need a fire that burns steadily
and brightly. This is the time to use your biggest pieces of hardwood fuel if you have it. Put
the biggest pieces at the back of the firebox and place the rest of the pieces compactly. A
densely built fire like this will produce the longest burn your furnace is capable of.
You will need to be cautious when building fires like this because if the air is turned down
too much, the fire could smoulder. Make sure the wood is flaming brightly before leaving
the fire to burn.
46
HeatPro Furnace Installation and Operation Manual
MAXIMUM
8.3.5.4 Maximum burn cycle times
The burn cycle time is the period between loading wood on a coal bed and the
consumption of that wood back to a coal bed of the same size. The flaming phase of the
fire lasts for roughly the first half of the burn cycle and the second half is the coal-bed
phase during which there is little or no flame. The length of burn you can expect from your
furnace, including both the flaming and coal bed phases, will be affected by a number of
things, such as:
•
firebox size,
•
the amount of wood loaded,
•
the species of wood you burn,
•
the wood moisture content,
•
the size of the space to be heated,
•
the climate zone you live in, and
•
the time of year.
•
the time cycle for the thermostat to call for heat.
The table below provides a very general indication of the maximum burn cycle times you
are likely to experience, based on firebox volume.
FIREBOX VOLUME
BURN TIME
<1.5 cubic feet 3 to 5 hours
1.5 c.f. to 2.0 c.f. 5 to 6 hours
2.0 c.f. to 2.5 c.f. 6 to 8 hours
2.5 c.f. to 3.0 c.f. 8 to 9 hours
>3.0 c.f. 9 to 10 hours
8.3.6 Control of the air inlet damper
Always turn the furnace on with the air inlet damper open. Once the temperature of the
wood, the combustion chamber and the chimney is stable, close the air inlet damper to
obtain a more efficient combustion.
To control the air inlet damper, use the switch on the side of the control box located at the
back of the furnace.
Reducing the combustion air will do two things. First, the combustion rate will decrease,
which will spread the thermal energy of the fuel over a longer period of time. In addition,
the velocity of the exhaust gas decreases, which allows better heat transfer in the heat
exchanger and chimney.
The closure of the main air intake reduces the intensity of the flames which indicates the
achievement of optimum performance. If the flames diminish in intensity at a point where it
almost disappears, it is an indication that the air inlet damper was closed too soon or the
firewood used is dry enough. If the wood is dry enough and the air control is closed when
the unit is at a stable temperature, the flames will decrease but remain strong and stable to
provide efficient heating.
47
HeatPro Furnace Installation and Operation Manual
8.4 Additional fresh air supply
When the furnace and the chimney are completely cold, it may be necessary to provide
fresh air by opening a door or a window for a few minutes while lighting the fire.
Take note that a house constructed or renovated in order to be airtight may lack the
volume of fresh air necessary for the proper combustion of a solid-fuel heating appliance.
In such a case, when starting up the fire, do not operate appliances that evacuate air
outside the house, such as:
• Range hood
• Air exchanger
• Clothes dryer
• Bathroom blower
• Ventilated central vacuum system
Exhaust blowers that are in a fuel storage room should be installed so as not to create
negative pressure in the room where the solid fuel appliance is located.
A fresh air supply may be necessary to prevent solid fuel units from rejecting products of
combustion into the house. The indications used to determine if an additional fresh air
supply is necessary are not appropriate for all the situations. When in doubt, it is
recommended installing a fresh air supply.
A fresh air supply may be needed if:
- Solid fuel units present anomalies, such as irregular draft, smoke return, bad
combustion, and/or reversed draft (whether there is combustion or not);
- Existing solid fuel units such as a stove or fireplace release odours, heat badly, cause
smoke returns, or reversed draft (whether there is combustion or not );
- The opening of a window, even slightly, in calm weather (windless), eliminates every
problem mentioned above ;
- The house is equipped with a tight vapour barrier and adjusted windows, and/or is
equipped with an interior air mechanical evacuation device ;
- There is excessive condensation on the windows in winter; and
- The house is equipped with a ventilation system.
If, according to these symptoms or other similar ones, there is insufficient combustion air, it
is necessary to ensure an additional combustion air supply (see Section 6: Combustion
Air).

HeatPro Furnace Installation and Operation Manual
8.5 Manual or thermostat control
From the factory, the opening and closing of the air inlet damper is manually activated by
the means of a switch located at the rear of the furnace. The switch has two positions;
opened and closed.
Position of the air control rod when the switch in the “closed” position.
For added comfort, the installation of an optional wall thermostat is recommended since it
will open the air inlet damper when the room temperature is below the set point of the
thermostat and will close the air inlet damper as the desired temperature is reached (see
Appendix 1: Optional Thermostat Installation).
If the heat sensors detect any overheating in the air jacket of the furnace, the air inlet
damper will close automatically regardless of the type of control used.
8.6 Ash drawer
Your furnace is equipped with an ash drawer to collect ashes produced by the combustion
of wood. The ash drawer is provided with two (2) wing nuts to hold the door in a close
position. Operating the furnace with the ash drawer open may seriously damage the
furnace. The drawer must be emptied regularly.
8.7 Prolonged power outage
To reduce the risk of overheating during a prolonged power outage (more than 10
minutes), it is recommended damper is closed. If your furnace is equipped with the
optional filter, remove the air filter to improve the circulation of air around the combustion
chamber of the furnace. Do not load the furnace more than 50 percent of its capacity to
prevent the risk of overheating,

HeatPro Furnace Installation and Operation Manual
9 Maintaining your wood heating system
9.1 Furnace maintenance
Your new furnace will give many years of reliable service if you use and maintain it
correctly. Some of the internal components of the firebox, such as firebricks, baffles and air
tubes, will wear over time under intense heat. You should always replace defective parts
with original parts (see Section 11: Exploded diagram and parts list). For firing each
load hot to begin a cycle as described above will not cause premature deterioration of the
furnace. However, letting the furnace run with the air control fully open for entire cycles can
cause damage over time. The hotter you run the furnace throughout burn cycles, the more
quickly its components will deteriorate. For that reason, never leave the furnace
unattended while a new load is being fired hot.
9.1.1 Ash removal
Ash should be removed from the firebox every two or three days of full-time heating. Do
not let the ash build up in the firebox because it will interfere with proper fire management.
The best time to remove ash is after an overnight fire when the furnace is relatively cool,
but there is still some chimney draft to draw the ash dust into the furnace and prevent it
from coming into the room.
After ashes have been removed from the furnace and placed in a tightly covered metal
container, they should be taken outside immediately. The closed container of ashes should
be placed on a non-combustible floor or on the ground well away from all combustible
materials pending final disposal. Ashes normally contain some live charcoal that can stay
hot for several days. If the ashes are disposed of by burial in soil or otherwise locally
dispersed, they should be retained in the closed container until all cinders have thoroughly
cooled. Other wastes shall not be placed in this container.
NEVER STORE ASHES INDOORS OR IN A NON-METALIC CONTAINER OR ON A
WOODEN DECK. ALWAYS LEAVE THE CONTAINER ON A NON-COMBUSTIBLE
FLOOR.
9.1.2 Cleaning door glass
Under normal conditions, your door glass should stay relatively clear. If your firewood is
dry enough and you follow the operating instructions in this manual, a whitish, dusty
deposit will form on the inside of the glass after a week or so of use. This is normal and
can be easily removed when the furnace is cool by wiping with a damp cloth or paper towel
and then drying. Never try to clean the glass when the furnace is hot.
In spring and fall the furnace will cycle less often. You may see some light brown stains
forming, especially at the lower corners of the glass. This indicates that the combustion
has been incomplete and some of the smoke has condensed on the glass. When the
weather is mild, you may find that letting the fire go out is better than trying to maintain a
continuous fire. Use the technique described above for building a fire to take the chill off
the house.
50
HeatPro Furnace Installation and Operation Manual
If you do get brown stains on the glass, you can remove them with special cleaners for
wood furnace glass doors. Do not use abrasives to clean your furnace’s door glass.
The deposits that form on the glass are the best indication of the quality of your fuel and
how well you are doing in operating the furnace. Your goal should be clear glass with no
brown stains. If you continue to see brown stains on the glass, something about your fuel
and operating procedure needs to be changed. Stains on the glass indicate incomplete
combustion of the wood, which also means more smoke emissions and faster formation of
creosote in the chimney.
If you see brown streaks coming from the edge of the glass, it is time to replace the gasket
around the glass. Visit your furnace retailer to get the self-adhesive glass gasket and
follow the Section 9.1.4: Replacement of the glass and gaskets instructions for
installation.
• Check the glass regularly to detect any crack or damage. Replace damaged glass
immediately; do not use the furnace with a broken glass.
9.1.3 Door adjustment
In order for your furnace to burn at its best efficiency, the door must provide a perfect seal
with the firebox. Therefore, the gasket should be inspected periodically making sure to
obtain an air-tight fit. Air tightness can be improved with a simple latch mechanism
adjustment. If the adjustment is not sufficient, replace the door gasket with a new one (see
Section 9.1.4: Replacement of the glass and gaskets).
Door adjustment procedure
1. Unscrew the locking pin (B) and nut (A) from the door (see image below).
2. To increase the pressure of the door on the gasket, turn the handle. Counter-clockwise,
to reduce the pressure of the door on the cord, turn the handle clockwise to clockwise.
3. Finally, screw-in the locking pin (B) about 1/4" (6 mm) deep and make sure you lock it
with the nut (A).
51
HeatPro Furnace Installation and Operation Manual
9.1.4 Replacement of the glass and gaskets
After a year or more of use, the gasket of the door will compress and become hard which
can allow air to pass. You can check the air tightness of your door gasket by closing and
locking the door on a piece of paper. Check all around the door. If the paper slides easily
anywhere, it is time to replace the gasket.
Use a good quality gasket that you can purchase from your dealer. The correct size and
density of the gasket are important to ensure a good seal.
Prior of removing the defective glass, you need to remove the door gasket. Inspect the
door gasket before it is reinstalled to make sure it is in good condition. We suggest
replacing the door and glass gasket at the same time as their level of wear over time is
similar.
For the following steps, wearing gloves and safety glasses are recommended for handling
seals can irritate the skin and the glass can be sharp.
- To replace the door gasket, use the steps 1 to 3 and 10 outlined below;
- To replace the glass, use the steps 1 to 6 and 9 to 10 outlined below;
- To replace the glass gasket, use the steps 1 to 10 outlined below;
1. Remove the door (F) and place it on a stable work surface, handle down.
2. Using pliers, remove the door gasket (A).
3. Using a scraper or a small flat screwdriver, remove the adhesive left in the gasket
grove in the door then clean the surface using a commercial vacuum.
4. Use a Phillips screwdriver or a power drill to remove the screws (B) that holds the glass
retainer (C).
5. Remove the glass frame (D)
6. Remove the glass (E) (or pieces of glass if it is damaged) and clean the inside of the
door frame.
7. Remove the old glass gasket.
8. Install the new gasket on the glass. Remove a part of the paper covering the gasket
adhesive. Center the gasket on the edge of the glass so that when folded and glued,
the gasket is equal on both sides. Do not stretch the gasket during installation. Remove
a majority of the paper, turn the glass to facilitate and complete the installation of the
gasket. When you return to the starting point, cut the gasket so that the ends overlap
by about 1/2" (13 mm).
52
HeatPro Furnace Installation and Operation Manual
9. Install the glass (E) and glass frame (D) and centering it in the frame of the door and
install the glass retainer frame (D) and glass retainers (C) taking care not to over
tighten the screws (B). Note that the two main causes of glass breakage are unequal
position in the door and screws too tight.
10. Install the new door gasket (A). To do this, use about 1/4" (6 mm) of adhesive to the
bottom of the groove that holds the gasket in the door. Then lay the new gasket starting
from the center of the hinge side and taking care not to stretch the gasket during
installation. Leave about 1/2" (13 mm) of gasket exceed the frame of the door. Once
jointed, push the fibers protruding towards the inside of the groove in the adhesive.
Install the door and let dry for 24 hours before using the furnace.
Do not abuse the glass door by striking or slamming shut. Do not use the furnace if the
glass is broken. To change the glass, perform the same operation described above.
9.1.5 Cleaning and painting the furnace
Do not attempt to clean or paint the furnace when the unit is hot. Painted surfaces
can be wiped down with a damp cloth. Plated or enameled surfaces may be scratched by
abrasive cleaners. To maintain the finish at its original brilliance, use only a damp soft cloth
to clean plated or enameled surfaces.
If the paint becomes scratched or damaged, you can give your wood furnace a brand new
look by repainting it with heat-resistant or enamel finish paint. Before painting, roughen the
surface with fine sand paper, wipe it down to remove dust, and apply two thin coats of
paint. For best results, use the same paint that was originally used on the furnace, which is
available in spray cans. See your dealer for details.
53
HeatPro Furnace Installation and Operation Manual
9.1.6 Heat exchangers care
Heat exchangers must be cleaned thoroughly at the end of every heating season. During
summer, the air in basements is damper and with minimal air circulation within the furnace,
it can mix with creosote and/or sooth deposits in the exchangers to form an acid that could
accelerate the corrosion process and induce premature decay of the steel. Corrosion
damages are not covered under warranty.
The smoke pipe and exchangers must be inspected regularly during the heating season.
Access to the exchangers is easy and does not require tools;
1. Unscrew the wing nut (B) and remove the washer (C) on the exchanger access door
(see Detail B).
54
HeatPro Furnace Installation and Operation Manual
2. Move the baffle of the combustion chamber forward (see Detail A).
3. Use the tool provided, clean the three exchanger pipes (see Detail C).
55
HeatPro Furnace Installation and Operation Manual
4. Dirt in the lateral exchangers (1 and 3) falls into the combustion chamber at the rear.
5. Dirt in the central exchanger (2) will be removed from the front or the rear of the
furnace. If you remove dirt from the central exchange to the back of the furnace,
remove the black pipe connector in order to dispose of the dirt.
6. Then, check that the baffle is clear of ash and reposition it in its original position
towards the back of the combustion chamber.
56
HeatPro Furnace Installation and Operation Manual
7. Close the exchanger access door and secure it using the washer (C) and wing nut (B)
(see Detail D).
8. If you have performed maintenance from the back part of the furnace, reinstall the
black pipe connector and secure it with three screws.
9.2 Chimney and chimney connector maintenance
9.2.1 Why chimney cleaning is necessary
Wood smoke can condense inside the chimney connector and chimney, forming a
combustible deposit called creosote. If creosote is allowed to build up in the venting
system, it can ignite when a hot fire is burned in the furnace and a very hot fire can
progress to the top of the chimney. Severe chimney fires can damage even the best
chimneys. Smouldering, smoky fires can quickly cause a thick layer of creosote to form.
When you avoid smouldering so the exhaust from the chimney is mostly clear, creosote
builds up more slowly. Your new furnace has the right characteristics to help you to burn
clean fires with little or no smoke, resulting in less creosote in the chimney.
9.2.2 How often should you clean the chimney?
It is not possible to predict how much or how quickly creosote will form in your chimney. It
is important, therefore, to check the build-up in your chimney monthly when getting used to
the new furnace until you determine the rate of creosote formation. Even if creosote forms
slowly in your system, the chimney should be cleaned and inspected at least once each
year.
Contact your local municipal or provincial fire authority for information on how to handle a
chimney fire. Have a clearly understood plan to handle a chimney fire.
57
HeatPro Furnace Installation and Operation Manual
CAUTION: IT IS RECOMMENDED CLEANING THE HEAT EXCHANGERS, FLUE PIPE
AND CHIMNEY THOROUGHLY AT THE END OF THE HEATING SEASON IN ORDER
TO PREVENT CORROSION DURING THE SUMMER MONTHS, CAUSED BY
ACCUMULATED ASH.
9.2.3 Cleaning the chimney
Chimney cleaning can be a difficult and dangerous job. If you don’t have experience
cleaning chimneys, you might want to hire a professional chimney sweep to clean and
inspect the system for the first time. After having seen the cleaning process, you can
decide if it is a job you would like to take on.
The most common equipment used are fibreglass rods with threaded fittings and stiff
plastic brushes. The brush is forced up and down inside the chimney flue to scrub off the
creosote.
The chimney connector assembly should always be cleaned at the same time the chimney
is cleaned.
CAUTION: Operation of your furnace without the baffle may cause unsafe and hazardous
temperature conditions and will void the warranty. NOTE: Before installing the firebrick,
check to ensure that none are broken or damaged in any way. If so, have the damaged
ones replaced. Check the firebrick for damage at least annually and replace any broken or
damaged ones with new ones. Inspection and cleaning of the chimney is facilitated by the
removable baffle.
9.3 Smoke pipe inspection
• The smoke pipe must be inspected regularly during the heating season.
• The pipe must be examined carefully to detect any defect or damage.
• The pipe can be reassembled if no defect is detected and the defective pipe must be
replaced immediately.
• INSPECT FLUE PIPES, FLUE PIPE JOINTS, AND FLUE PIPE SEALS REGULARLY
TO ENSURE THAT SMOKE AND FLUE GASES ARE NOT DRAWN INTO, AND
CIRCULATED BY, THE AIR-CIRCULATION SYSTEM
9.4 Blower motor maintenance
Periodic cleaning of the blower housing and louvers as well as blower and blower blades
using a vacuum cleaner is necessary in order not to affect performance and cause
overheating of the latter.

12.3 The benefits of low emissions and high efficiency
The low smoke emissions produced by the special features inside the Brand Model firebox
mean that your household will release up to 90 percent less smoke into the outside
environment than if you used an older conventional wood furnace. But there is more to the
emission control technologies than protecting the environment.
The smoke released from wood when it is heated contains about half of the energy content
of the fuel. By burning the wood completely, your furnace releases all the heat energy from
the wood instead of wasting it as smoke up the chimney. Also, the features inside the
firebox allow you to reduce the air supply to control heat output, while maintaining clean
and efficient flaming combustion, which boosts the efficient delivery of heat to your home.
The emission control and advanced combustion features of your furnace can only work
properly if your fuel is in the correct moisture content range of 15 to 20 percent. See
PART 2 –OPERATION, MAINTENANCE AND TROUBLESHOOTING for suggestions on
preparing fuel wood and judging its moisture.
12.4 The SBI commitment to you and the environment
The SBI team is committed to protecting the environment, so we do everything we can to
use only materials in our products that will have no lasting negative impact on the
environment.
12.4.1 What is your new furnace made of?
The body of your furnace, which is most of its weight, is carbon steel. Should it ever
become necessary many years in the future, almost the entire furnace can be recycled into
new products, thus eliminating the need to mine new materials.
The paint coat on your furnace is very thin. Its VOC content (Volatile Organic Components)
is very low. VOCs can be responsible for smog, so all the paint used during the
manufacturing process meets the latest air quality requirements with regards to VOC
reduction or elimination.
The air tubes are stainless steel, which can also be recycled.
The C-Cast baffle is made of an aluminosilicate fibre material that is compressed with a
binder to form a rigid board. C-Cast can withstand temperatures above 2,000 °F. It is not
considered hazardous waste. Disposal at a landfill is recommended.
Lightweight firebrick is made of pumice and cement. Pumice is in fact volcanic rock, a
naturally green product found in the Northwest United States. Disposal at a landfill is
recommended.
The door and glass gaskets are fibreglass which is spun from melted sand. Black gaskets
have been dipped into a solvent-free solution. Disposal at a landfill is recommended.
The door glass is a 5 mm thick ceramic material that contains no toxic chemicals. It is
basically made of raw earth materials such as sand and quartz that are combined in such
a way to form a glass at high temperatures. Ceramic glass will not remelt in the same way
as normal glass, so it should not be recycled with your regular household products.
Disposal at a landfill is recommended.

13.2 Smoke detector
We highly recommend the use of a smoke detector. It must be installed at least 15 feet
(4.57 m) from the appliance in order to prevent undue triggering of the detector when
reloading.
13.3 Chimney fire
A Chimney fire will happen when the flame from an uncontrollable fire ignites the sooth
and creosote deposits in a neglected venting system. It will often happen when burning
cardboard, branches or small dry pieces of wood. The first signs of a chimney fire are:
1.
A rumble.
2.
Smoke pipe becomes extremely hot.
3.
Sparks or even flames shoot out of the chimney
In the event of a chimney fire, first call your local fire department and water the roof
in the vicinity of the chimney.
Make sure that the furnace door and the air intake damper are closed (if need be, lower
the thermostat setting and CLOSE the barometric draft damper manually if one is
installed). Close also the switch on the control box.
In the event of uncontrollable fire (caused by a wrongful operation or excessive chimney
draft), follow the same procedure as in a chimney fire but you must then OPEN the
barometric draft damper manually if one is installed.
