8 CHIMNEY AND DRAFT
This furnace must be connected to a chimney certified for use with wood burning heating appliances, a 6-inch diameter
chimney is recommended.
The unit is not to be connected to a chimney flue serving another appliance. If the chimney draft exceeds 0.06 IN.W.C.,
a barometric draft control should be installed on the smoke pipe. Never install a manual damper. The barometric control
must be adjusted so that the maximum draft measured at the furnace outlet does not exceed 0.06 IN.W.C. Excessive
draft can overheat the appliance and reduce burn time. Conversely, a lack of draft can lead to poor combustion and
smoke returns.
9 SAFETY RULES
WARNING! THE INFORMATION GIVEN ON THE CERTIFICATION LABEL AFFIXED TO THE APPLIANCE
ALWAYS OVERRIDES THE INFORMATION PUBLISHED, IN ANY OTHER MEDIA (OWNER’S MANUAL,
CATALOGUES, FLYERS, MAGAZINES OR WEB SITES).
9.1 GENERAL REQUIREMENTS
Make sure the chimney outlet and the pipes are clean and in good condition.
Do not use chemical products or liquids to light the fire.
Do not burn wood coated with paint, glue or chemical products.
Do not burn wastes or flammable liquids such as gasoline, naphtha, motor oil, or other unsuitable
matters.
Do not store wood in the vicinity of the furnace. Respect the required clearances between combustible
materials and the source of heat.
WARNING! THE ASH DRAWER AND EXCHANGERS ACCESS PANEL GET VERY HOT. DO NOT MANIPULATE
WITH BARE HANDS.
WARNING: This product can expose you to chemicals including carbon monoxide, which
is known to the State of California to cause cancer, birth defects or other reproductive
harm. For more information go to
www.P65warnings.ca.gov/

13
9.2 ODOUR FROM THE PAINT
It is normal that smoke and odours emanate from the unit when you first light it. It is recommended to burn it at high rate
and ventilate the building until the odours disappear. The smoke is not toxic. This should be done before the ducts
are connected to the furnace to prevent smoke dispersion in the house.
9.3 ASH DISPOSAL
Ashes must be placed in a metal container with a tight fitting lid. The container should be stored outdoor, well away from
combustible materials. This container should not contain any other type of waste. If the ashes are meant to be buried in
soil, wait until all embers have thoroughly cooled before burying.
9.4 CREOSOTE BUILD-UP AND REMOVAL
When wood is burned slowly, it produces tar and other organic vapours which, when combined with moisture, form
creosote. The creosote vapours condensate in a relatively cool chimney flue. As a result, creosote residues accumulate
inside the flue lining and the exchangers.
To minimize the frequency of the chimney cleaning, buy your firewood at least one year before using it. Store it in a dry
place in order to obtain the minimum moisture rate and optimize the efficiency. Do not store wood or combustible
materials within the installation minimum clearances or the space required to reload the appliance and remove ashes.
When ignited, creosote produces an extremely hot fire inside the chimney.
In the first year of use, inspect the chimney system at regular intervals to determine a cleaning cycle. Depending on the
type of wood used and its quality, a mid-season cleaning may be required. A yearly cleaning is mandatory. If a significant
layer of creosote has accumulated, it must be removed immediately to eliminate the risk of chimney fire.
Remember that a small, hot fire is preferable to a large smouldering one to prevent creosote build-ups within the system.
Prepare an emergency procedure in case of a chimney fire. It is recommended to clean the heat exchangers
thoroughly at the end of season in order to prevent corrosion.
9.5 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.
9.6 DOOR GLASS
To maintain a clean and safe installation, do not build your fire too close to the glass or allow logs to lean on the
glass.
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.
An intense fire will help keep the glass clean. However, in the event that your glass gets stained, which should
not occur under normal operating conditions, you will have to clean it using a wet cloth and a fireplace glass
cleaner. Clean the glass ONLY when the unit has cooled down. Do not use abrasive cleaner.
WARNING! AVOID KNOCKING OR SCRATCHING THE GLASS. IT COULD CRACK OR BREAK.
Glass specifications:
Made of 5/32" (4 mm) thick ceramic glass.
Do not operate your wood furnace with a broken glass, as this could seriously damage your furnace.
You can purchase a replacement glass from your Caddy dealer.
9.7 ASH DRAWER
Your furnace is equipped with an ash drawer to collect ashes produced by the combustion of wood. This drawer must
not be left open during combustion as this may cause over firing and serious damages to the furnace. Moreover, the
additional air created could cause the dispersion of ashes in the ventilation system. The drawer must be cleaned
weekly. Use a vacuum cleaner to remove any ashes around the drawer in order to avoid the dispersion of ashes
in the ventilation system.
It is important that the door, the heat exchanger door and the ash drawer be kept closed while the
appliance is in use. Maintain all gaskets in good condition; in case of deterioration, contact your
dealer for a genuine replacement gasket.

14
9.8 ASH GRATE
You must replace the ash grate if it is damaged and a replacement may be obtained from your dealer.
9.9 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
Bathroom fan
Air exchanger
Ventilated central vacuum system
Clothes dryer
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 spilling smoke 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 to install 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.
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 11.8 FRESH AIR SUPPLY INSTALLATION

10 FIREWOOD
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%.
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 would not 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.
Log length
Logs should be cut about 1" (25 mm) shorter than the firebox so they fit in
easily. Pieces that are too long make 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.
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 re-split the wood before stacking to dry.

16
How to dry firewood?
Firewood that is not dry enough to burn is the cause of most complaints
about wood burning appliances. Continually burning green or
unseasoned wood produces more creosote and involves lack of heat
and dirty glass door. See section 16 FURNACE MAINTENANCE for
concerns about creosote.
Things to consider in estimating drying time:
Firewood takes a long time to dry.
Firewood dries mostly from the exposed ends. Long pieces of wood should be cut to “firewood” length if expected
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.
Softwoods take less time to dry than hardwoods.
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 woodshed.
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.
Judging firewood moisture content
You can find out if some firewood is dry enough to burn by using these guidelines:
Use the wood moisture meter provided with your furnace to test your firewood. Testing the middle of a freshly
split piece of wood is the most accurate test point.
Cracks form at the ends of logs as they dry.
As it dries in the sun, the wood turns from white or cream colored 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.

WARNING! ONLY USE WIRES SUITABLE FOR 167 °F (75 °C) OR MORE.
11.1 BLOWER INSTALLATION
To use the wood only and parallel add on configuration, the blower assembly (PA08585 or PA08586 – sold separately)
is required. The installation instructions are provided with the blower.
11.2 HOT AIR PLENUM TEMPERATURE PROBE INSTALLATION AND CONNECTION (RTD)
On the Caddy Advanced, a RTD must be installed on left the side of the furnace using the support provided with the unit.
The RTD is a sensor that reads the temperature inside the hot air plenum. It is critical to the good operation of the
furnace. It is important that the RTD and the RTD support be properly fixed onto the hot air plenum.
STEP 1: Secure the RTD bracket (A) with two screws found in the manual kit.
STEP 2: Using a drill and a 9/32" bit, drill a hole in the hot air plenum so that the RTD rod can pass into it.
STEP 3 & 4: Secure the RTD in place on the hot air plenum using the two self-tapping screws provided with the owner’s
manual.

STEP 5: Connect the RTD probe
(B) to the furnace block terminal
identified with a “R”.
STEP 6: Use the wire grommets (C)
supplied with the manual to attach
the wires from the RTD to the
furnace.
11.3 UNIT LOCATION
For a safe and quiet operation, the furnace must be leveled in both directions and supported evenly to ensure
