1. INTRODUCTION
Take note that this furnace operates like an EPA wood burning stove. This applies to the lighting, the ember bed, and
the minimum combustion air intake which was determined based on the use of good seasoned cordwood.
The Max Caddy furnace was tested and approved according to the CSA B415.1-10 Standard.
To optimize the efficiency of your furnace, here is some advice that you should follow when installing or operating your
Max Caddy.
• Respect the local codes (when in doubt, consult your local dealer);
• Make sure your furnace is installed according to the instructions on the certification label;
• All controls and adjustments must be performed by a qualified technician. The blower speed must conform to
the recommendations of local codes and should respect the static pressure ranges in the warm air plenum of
the furnace.
We recommend that our wood burning 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).

7. CHIMNEY AND DRAFT
This furnace must be connected to a chimney certified for use with wood burning heating appliances. A 7-inch chimney
and connector must be installed for the Max Caddy if it is used as a wood-oil unit, a wood-electrical-oil unit or if an oil
option may be installed in the future. If the furnace is to be used as a wood only unit or a wood-electric, then a 6-inch
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.
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 evacuation pipe on the wood side, no matter what type of furnace
(WOOD, WOOD/ELECTRIC OR WOOD/OIL). The adjustment 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 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.
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 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.
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 chimney flue. As a result, creosote residues
accumulate inside the flue lining and the exchangers.
N.B.: 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.
11
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 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.
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 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 cleanser.
WARNING: Avoid knocking or scratching the glass. It could crack or break.
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 and a replacement may be obtained from your dealer.
