7. CHIMNEY AND DRAFT
This furnace must be connected to a chimney certified for use with wood burning heating appliances. A 6chimney and
flue pipe are mandatory for the Mini-Caddy.
The unit is not to be connected to a chimney serving another appliance. If the flue pipe draft exceeds -0.06 IN.W.C., a
barometric damper should be installed. Never install a manual damper. The barometric damper must be adjusted so
that the maximum draft measured in the flue pipe does not exceed -0.06 IN.W.C. Please note that a draft exceeding
-0.06 IN.W.C. could produce an uncontrollable fire. On the other hand, the minimum draft required is 0.04 IN.W.C.
in the flue pipe on the wood side, no matter what type of furnace (WOOD or WOOD / ELECTRIC). The air inlets
should in no case be modified to increase combustion.
8. 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 AND/OR WEB SITES).
8.1. GENERAL REQUIREMENTS
MAKE SURE THE HEAT EXCHANGERS, THE FLUE PIPES AND THE CHIMNEY 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.

10
AIR DUCTS SERVING A GARAGE SHOULD NOT BE CONNECTED TO OTHER PARTS OF A HOUSE AND THE
DUCTING SERVING A HOUSE SHOULD NOT BE CONNECTED TO A GARAGE.
WARNING
THE ASH DRAWER AND EXCHANGERS ACCESS PANEL GET VERY HOT. DO NOT MANIPULATE WITH BARE
HANDS.
8.2. 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 house 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.
8.3. 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.
8.4. 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 flue pipe. As a result, creosote residues accumulate
inside the flue pipe and the heat exchangers.
N.B.: To minimize the frequency of the chimney cleaning, buy your firewood at least one year before using it. In order
to obtain the minimum moisture rate and optimize the efficiency, store it in a dry place, under a shelter. 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 semi-annual 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. Prepare an
emergency procedure in case of a chimney fire. It is recommended to clean the heat exchangers the flue pipe and
the chimney thoroughly at the end of season in order to prevent corrosion.
8.5. 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.
8.6. 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 a too low burning regime. 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, 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 cleanser.
WARNING: AVOID KNOCKING OR SCRATCHING THE GLASS. IT COULD CRACK OR BREAK.

11
8.6.1. GLASS SPECIFICATIONS
The glass is made of 3/16" (5mm) 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 PSG dealer.
8.7. 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
regularly. 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 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.
8.8. ASH GRATE
You must replace the ash grate if it is damaged. A replacement may be obtained from your dealer.

equipment » standard in Canada and NFPA 90B « Standard for the installation of warm air heating and air conditioning
system » in the United States. Moreover, for all electrical connection, the Canadian standard CSA C22.1 « Canadian
electrical code » and in the United-States NFPA 70 standard « National Electrical Code » must be followed.
All controls and adjustments must be performed by a qualified technician. The blower speed must conform to the
recommendations of the Warm Air Heating and Air Conditioning National Association and should respect the static
pressure ranges in the warm air plenum of the furnace
We recommend that our woodburning hearth products be installed and serviced by professionals who are certified in
the United States by NFI (National Fireplace Institute®) or in Canada by WETT (Wood Energy Technical Training) or in
Quebec by APC (Association des Professionnels du Chauffage).
Inspect the furnace to make sure that nothing has been damaged in the shipping. Pull out the wiring kit and the
instructions manual from the firebox of the furnace.
The following section contains installation instructions for the Mini-Caddy wood only, Mini-Caddy wood / electric and
Mini-Caddy add-on parallel configurations.
9.1. BLOWER ASSEMBLY INSTALLATION (PA08521 –SOLD SEPARATLY)
All of the Mini-Caddy configurations require the installation of the blower assembly. The blower assembly installation
instructions are provided with the blower.
9.2. LINK BOARD INSTALLATION AND CONNECTION
The following installation instructions are identical whether the furnace controls are located on the left or on the right of
the furnace. The most accessible side is preferred to facilitate the connection of auxiliary heating sources or for
servicing.
The components to be installed are in the combustion chamber of the furnace.
Remove the link board access panel.

14
Remove the four screws
on the furnace, located
on the side of the desired
installation. Keep the
screws.
Align the holes of the link board
housing with the holes on the side of
the furnace. Use the screws removed
in the previous step to secure the
housing to the furnace.
Once installed, the link board must be
connected to the power board with the
telecommunication wire. The wire is
located in the blower box. To access
it, remove the duct support.

15
Take the telecommunication wire and
pull it through the middle grommet on
the blower box
Once the telecommunication wire is
out run it along the back of the
furnace and pass it through the
grommet at the bottom of the link
board housing. Complete the
connection by plugging the 8 strands
telecommunication wire in the right
connector, shown by the arrow.

16
Your furnace should also be
connected to a 115V power
source. To do so, open the
cover of the power board
housing.
Connect the power cord to the
terminals N (Neutral) F
(Ground) L (Line). Refer to
wiring diagram for connecting
components. When done,
secure the wires with a BX
connector (not included) and
replace the blower box cover.

9.3. TOUCHSCREEN INSTALLATION AND CONNECTION
The touch screen is used to operate the system. It must be installed on the support provided at the back of the furnace,
on the same side as the link board housing.
Connect link board with the touch screen using the telecommunication wire provided with the user manual. Plug the
telecommunication wire in connector labeled LCD and pull it out of the board housing through the bottom grommet.
Simply run the wire on the side of the furnace. Replace the access panel of the link board. Note that the touch screen
is removable if access is restricted.

18
9.4. HOT AIR PLENUM TEMPERATURE PROBE INSTALLATION AND CONNECTION (RTD)
On the Mini-Caddy, a temperature probe (RTD) has to be installed on 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.
WARNING: USE WIRING SUITABLE FOR 75 °C (not included).
STEP 1: Remove the two screws already secured on the furnace on the side where you have chosen to install the link
