INTRODUCTION
To optimize the efficiency of your furnace, follow the following advices:
Respect the local codes (when in doubt, consult your local dealer).
Make sure your furnace is installed according to the instructions on the certification plate.
All controls adjustments must be performed by a qualified technician. The controls settings
and the blower speed must conform to the recommendations of the Warm Air Heating and Air
Conditioning National Association and respect the recommended static pressure ranges in the
warm air plenum of the furnace (see General Technical data, static pressure).
The wood burning AN-30 Add-on furnace is approved in line connection to an
existing oil furnace with a firing rate of 0.8 G.P.H. (US) to 1.2 G.P.H. (US).
1. CHIMNEY AND DRAFT
This furnace must be connected to a chimney certified for wood burning heating appliances; a
8” (200mm) connector and chimney is highly recommended.
Install the barometric damper provided with the furnace. Never install a manual damper.
The barometric damper 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.
2. SAFETY RULES
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 or motor oil.
 Do not install an automatic feeder on this furnace.
 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 GET VERY HOT, DO NOT HANDLE WITH
BARE HANDS.
ODOUR FROM THE PAINT
The furnace will release some smoke and odors when first fired; this is normal and will stop
when the paint has finished curing. Burn the unit at high rate with windows opened until the
smoke and smell is vented out.
ASH DISPOSAL
Ashes must be placed in a metal container with a tight fitting lid. The ash container should be
placed outside well away from all combustible materials. If the ashes are intended to be buried in
soil, wait until all cinders have thoroughly cooled before burying.
CREOSOTE BUILD-UP AND REMOVAL
When wood is burned slowly, it produces tar and other organic vapors, which when combined
with moisture, produce creosote. The creosote vapors condense in a relatively cool chimney and
flue. As a result, creosote residues accumulates on the chimney and flue linings.
N.B.: To minimize the frequency of the chimney cleaning, buy your firewood at least one year
before using it. Store 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 and space required to reload the appliance and remove the ashes.
When ignited, the creosote produces an extremely hot fire inside the chimney.
To avoid this situation, it is important to do the rotation of wood. Inspect the chimney system at
regular intervals to determine a cleaning cycle. A weekly cleaning might be required during mild
temperature periods but a monthly cleaning should be sufficient during cold periods. If a
significant layer of creosote has accumulated, it should be removed immediately to
eliminate the risk of a chimney fire. Remember that a small hot fire is preferable to a large
smouldering one that can deposit creosote within the system. An emergency plan is necessary in
case of a chimney fire. It’s important to clean up the exchangers at the end of season to prevent
corrosion.
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 a false alarm when refueling the fire.

ASH DRAWER
Your appliance 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 will cause over firing and
serious damage to the furnace.
The drawer must be cleaned regularly.
ASH GRATE
In case of ash grate damage, contact your dealer to get a replacement.
2. APPLIANCE INSTALLATION
Before installation, please read the instructions carefully and make sure you
understand them:
The furnace must be installed in a state of the art manner. Installation must be made in
accordance with the CSA B.365(Canada) and NFPA 211(USA) standards concerning the
normalization of solid fuel units. For installation in United Sates, also refer to NFPA
90B(USA) « Warm Heating and Air Conditioning Systems ». If modifications have to be
made to the existing furnace, these have to be conform with the CSA B.139 (Canada) and
NFPA 31 (USA) regulation for oil furnaces.
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 and the
cleaning tools from the heat exchangers.
UNIT LOCATION
The furnace must be installed where outside air supply will be sufficient for proper combustion.
In airtight houses, it might be necessary to install an outside air inlet.
The furnace must be positioned so that the connector is as short as possible to minimize the
use of 90oelbows.
The owner must ensure a proper installation to allow a safe operation of the
appliance.
5
It is mandatory that the door and the ash drawer be kept
closed while the appliance is in use.
Maintain all seals in good condition ; in case of deterioration,
contact
y
our dealer for re
p
lacement.

6
MATCHING THE TRANSFER DUCT BETWEEN THE TWO HEAT
GENERATORS
Install the plenum and heating ducts in line as in option 1 of appendix 1. In series
connection should be considered only if in line connection is not feasible.
If the ducts are installed in series (appendix 1, option 2) and the oil furnace’s fan limit
control is mounted on the plenum, the divider in the plenum must be installed at least 5”
(127 mm) above the fan limit control casing. This divider must be air tight.
Do not install connecting ducts in a way that would allow inversion of the air flow.
The transfer duct between the existing furnace and the add-on must be at least 240
square inches and deviations radius must be at least 6”. (see the drawing on the following
page)
Do not remove any safety device from the existing furnace.
You must determine the air flow through the existing furnace before installing the AN-
30 add-on:
1. Run the oil furnace for at least 15 minutes, or until it reaches its maximum
temperature.
2. With a thermometer, measure the temperature of the cold air entering the furnace
and that of the air exiting the furnace in the hot air plenum.
The temperature rise is obtained by subtracting the cold air return temperature from
that of the air exiting in the hot air plenum..
3. Make the following verifications (OIL)):
CFM = orifice size (SI) x 39 023 x E
1.21 x T
CFM = orifice size (Imperial) x 140 000 x E
1.1 x T
or
E : Average heat generator efficiency (0.75)
T : Temperature rise (ºC)
4. After the installation of the add-on, the original numbers must be restored in order
to maintain a constant air flow through the furnace.

MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS FOR AN-30 ADD-ON
N.B. This appliance must be installed in accordance with the instructions on the certification
plate applied on the unit.
N.B. THE AIR RETURN CONDUITS SHOULD BE AT LEAST EQUAL TO THE COLD AIR PLENUM
DIMENSIONS.
7
2"

PIPE CONNECTOR AND DAMPER
A 8” diameter chimney and connector approved for use with wood burning heating appliances are mandatory
for the AN-30. Install the barometric control provided with the furnace. Do not install a manual damper.
It’s strictly forbidden to connect a solid fuel burning appliance to a chimney deserving a propane or
natural gas appliance. Regulation CAN-CSA-B365.1.
For a proper installation, follow the following advices :
1. All the joints of the evacuation pipe connections must be secured with three screws.
Make sure that each screw goes through the inner wall of both connectors (male and female). See
pictures below showing a male-female coupling.
2. A minimum upward slope of 1/4 inch per horizontal foot must be respected.
DAMPER
The barometric damper must be adjusted so that the maximum draft measured at the
furnace outlet is limited to -0.06 in. w.c.. However, the minimum draft to be respected at all
times is -0.04 in. w.c. on the solid fuel side, no matter what type of furnace.
WARNING: DRAFT HIGHER THAN -.06” W.C. MAY CAUSE AN UNCONTROLLABLE
FIRE.
8
Before proceeding to connection, remove all accessories, such as
scraper, shovel and poker from the evacuation pipe of the furnace.
PROPER INSTALLATION WRONGFUL INSTALLATION
CAUSES RESTRICTION

COMBUSTION AIR
When the furnace and the chimney are completely cold, it might be necessary to provide
fresh air by opening a door or a window for a few minutes before lighting.
Take note that a house constructed or renovated in order to be airtight is liable to lack fresh
air which is necessary for a proper combustion and operation of heating appliances.
When starting up the fire, do not operate appliances which evacuate air outside the house
such as:
- Range hood
- Air exchanger
- Cloths dryer
- Bathroom fan
- Ventilated central vacuum system
NOTE:
It is recommended to install an outside air inlet of minimum 4” in diameter in or near the
room where the heating appliance is installed (see drawing below). When doing so, it is
preferable to choose a wall which is not exposed to dominant winds, depending on the
conditions surrounding your house.

ELECTRICAL CONNECTIONS
The following instruction do not replace those of the local code.
AN-30 ADD-ON
Installation and verification of this appliance must be done by a qualified service man.
Mount the fan limit control on the side of the furnace opposed to the transfer duct between the two
heat generators. Install the damper motor on the upper right side of the front panel (mounting holes are
already drilled).
If the ducts are connected in series (appendix 1, option 2) and the fan limit control of the existing
furnace is located in the plenum, the divider must be installed at least 5" (127 mm) above the fan limit
casing. This divider must be airtight.
All wiring and connections must be done according to the diagram. The controls of the two
furnaces must be interconnected.
ATTENTION : ONLY USE WIRES SUITABLE FOR 75° C.
THERMOSTAT
The thermostat must be installed on an inside wall in a location where it is not likely to be
affected by the draft coming from an air outlet. It must be installed at a minimum of 55 inches
above the floor. The two thermostats on a combined system must be installed at same
height. In normal bi-energy operation, the wood system thermostat should be set 2oto 3o
higher than the electric system thermostat.
FAN CONTROL
The fan control settings vary depending on the type of installation. The “fan off” setting is
preset at 110oF at the factory. This setting should provide a proper operation in most
installations. The “fan on” setting is factory set at 150oF.
It is preferable for a prolonged operation of the blower that the “fan off” setting be low
enough. But a “fan off” setting too low will cause undesirable cold air circulation. To modify
the setting, turn the indicator at the desired position on the temperature scale of the fan limit
control.
The adjustment of all controls must be performed by a qualified technician. The controls
setting and the blower speed must conform to the recommendations of the “Warm Air Heating
and Air Conditioning National Association”. To obtain a continuous air circulation during
summer, simply move the manual switch of the fan limit control from the “auto” to the
“manual” position.

11
The switch located below the fan limit control operates the low speed either at the “on”
position or the “off” position. For a better efficiency we recommend to leave the high speed
on automatic for heating and to use the low speed for continuous air circulation.
It is possible that the blower and motor pulleys have to be replaced in order
to obtain the desired air flow through the system. (The use of a more powerful
motor is permitted on the belt driven blowers) Direct drive motors may not be
replaced but they may be upgraded by replacing the capacitor.
WARNING : the blower of the existing furnace may not be changed.
4. OPERATING INSTRUCTIONS
Start the existing heat generator periodically to make sure it is in good working
condition
On the wood only furnaces, the thermostat 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 fan limit control activates the blower motor at the speed selected
for wood heating.
The chain that links the air inlet latch to the damper motor must have a play of 1/8 inch.
When there is no call for heat, the air inlet latch must be completely closed and the chain
must be hooked up to the servo-motor at “8 o’clock”. *
• (With all reserve for the minimum air intake to be increased depending on the type and
quality of the combustible).
•
LIGHTING
NEVER USE CHEMICALS OR FLAMMABLE LIQUIDS TO LIGHT THE FURNACE
1. Open the door
Note: If there already is a good ember bed in the furnace, go to step b) Pre-heating.
2. Place one or two pieces of dry kindlings at the front of the furnace.
3. Place newspaper strips on top of the kindlings.
4. Cover the newspaper with small pieces of dry wood.
5. Add newspaper strips, then light the fire a low as possible and leave the door 1/2" (13 mm)
opened. If lighting fails, you might experience a smoke back draft through the air inlets.

12
PREHEATING
1. Once the kindling is well ignited or the coals revived, put 2 or 3 fire logs in such a way that
the flames can interlace between the logs and close the door.
2. Wait 15 to 20 minutes then proceed with loading the furnace.
HEATING
1. When reloading the furnace, first spread the embers at the center of the combustion
chamber before adding new logs.
2. Do not overload. Air must circulate freely in the upper part of the combustion chamber in
order to obtain an efficient operation of the appliance. Note that a small hot fire will
produce much less creosote than a large smouldering one.
PROCEDURE TO OPEN THE LOADING DOOR
TO MINIMIZE THE RISK OF A BACK DRAFT OPEN THE DOOR 1”
AND WAIT ABOUT 10 SECONDS BEFORE OPENING COMPLETELY.
THE PURPOSE IS TO STABILIZE THE PRESSURE INSIDE THE FURNACE.
EARLY SIGNS OF OVERFIRED FURNACE
1. Roaring fire.
2. Chimney connector is glowing red.
3- Extreme heat coming from the furnace.
If this occurs, DO NOT OPEN THE DOOR, shut-off the air inlet completely, and wait until the
glow has completely subsided.
ALWAYS KEEP THE DOOR AND THE ASH DRAWER CLOSED
(except for lighting and maintenance)..
WOOD AS HEATING FUEL

DO NOT USE CHEMICALS OR FLAMABLE LIQUIDS TO LIGHT THE FIREPAS

DO NOT BURN TRASHES’ GASOLINE’ NAPHTA’ MOTOR OIL OR OTHER SUCH
MATERIALS.
We recommend that you burn dry wood only.

13
There are two important factors to be considered when choosing a type of wood: the
moisture content and the wood density. Hardwood, such as maple, oak or beech will provide
better results because of the high density and minimal tar produced during combustion. It is
highly recommended to use wood that has been dried at least six months. Do not use coal
as heating fuel in this appliance.
Whenever a high rate of smoke is noticed in the room, you must:
1. Open doors and windows.
2. Make sure the furnace door is closed as well as the damper (if necessary, lower the
thermostat starting point or undo the chain of the damper and close manually the
barometric control).
3. When the furnace has cooled down, inspect the chimney to detect obstructions and consult
a specialist to determine the cause.
CARBON MONOXYDE IS A LETHAL GAS (ODOURLESS AND COLOURLESS), WHICH YOU
MUST BEWARE OF.
CHIMNEY FIRES
This might occur when the fire gets extremely hot and may be triggered by the burning
cardboard, branches or small pieces of wood when the flame ignites the creosote residues
accumulated in the evacuation system. The usual signs of chimney fire are:
1. Rumbling
2. The flue gets extremely hot
3. Flames or sparks are coming out of the chimney
In case of a chimney fire, call your local fire department immediately and sprinkle the
roof around the chimney with water.
Make sure that the furnace door is closed as well as the damper (if necessary, lower the
thermostat setting or release the chain of the damper and CLOSE the barometric damper
manually).
If the fire gets uncontrollable due to an improper use or because the draft is too strong,
follow the same procedure as in a chimney fire except that you will have to OPEN manually
the barometric damper.
LOCAL FIRE DEPARTMENT.

PROLONGED POWER OUTAGE
In case of prolonged power outage (more than 10 minutes), in order to diminish the risk of
overheating, it is recommended to :
- Make sure that the furnace’s damper is closed.
- Open the filter compartment of the existing furnace in order to facilitate the circulation
of air, through natural gravity, around the wood add-on combustion chamber.
5. MAINTENANCE
MAINTENANCE OF THE EXCHANGERS
The smoke pipe and the exchangers should be inspected regularly during the heating
season.
CHIMNEY MAINTENANCE
One of the most efficient methods is to sweep the chimney is using a hard brush. Brush up and down, soot
and creosote residues will come off the inside surface and fall at the bottom of the chimney where they may be
removed easily.
The chimney must be checked regularly and if creosote has accumulated, it must be removed to prevent
chimney fires. Cleaning on a monthly basis should be sufficient during the coldest months.
Smoke pipe inspection
- The smoke pipe should be inspected regularly during the heating season.
- If possible, the smoke pipe should be dismantled and cleaned.
- The smoke pipe should be inspected to detect any defect.
- If no defect is noticed, put the flue back in place; otherwise, it must be replaced.
- Use only wood as a combustible.
Seasoned hard wood logs, 18” to 22” long, are recommended as a combustible.
DOOR GASKET MAINTENANCE
It is important to maintain the door gasket in good condition. After a while, the gasket might sag which will
necessitate a door adjustment.

10. TROUBLESHOOTING
PROBLEMS CAUSES SOLUTIONS
1. Sudden drop in heating performance
after normal heating sequences. ash build-up in front of the lower air inlet that prevents the combustion air
from entering the combustion chamber,
sooting up the exchangers and flue
Unclog the air inlet and clean the
exchangers and flue pipe.
2. Does not heat well from the start ,
lacking draught Barometric damper adjusted wrong (openstoo much). Too much restriction
in the smoke pipe (too long or too many
elbows)
Adjust the barometric damper to
maintain the draught at -.06 " W.C.
Reduce the distance to the chimney to
10 feet max. Use 45 degree elbows
when possible. Do not use more than 3
90 degree elbows.
3.Furnace burn well, plenum gets hot
but there is little heat in the house. Poor ventilation system design, low static pressure, bad cold air inlet vs
warm air outlet ratio.
Redesign the ventilation system
4. Furnace burn excessive amount of
wood The wood thermostat is always calling for heat (too close to a cold air draft).
Damper constantly open. Deficient
insulation of the house. Ash drawer
opened or leaking air. Furnace too
small.
Move the thermostat. Adjust the air
intake damper . Balance the ventilation
system to increase the heat input in the
room where the thermostat is located.
5, Fan start-up is too slow. Fan “ON” setting too high. Return air is
too cold (temperature lower than 65
degrees). Limit control not well located
in the warm air plenum.
Lower the temperature starting point.
Usually, the limit control is set at 150
degrees, we can under certain
conditions, reduce this temperature.
Reduce the fresh air flow. Relocate the
limit control.
6. A lot of creosote, moderate heat
output. Wet wood, lack of draught. Barometric damper not properly adjusted. Sooted
up chimney.
Use dry wood. Adjust the barometric
damper. Clean the chimney flue and
the furnace exchangers.
7. Furnace burns well but the plenum
does notr get hot enough. Bad quality of wood. Too much air return, not enough heat outlets.
Deficient ventilation system.
Use only well seasoned hard wood.
Redesign the ventilation system.
