SECTION 1 –OPERATING INSTRUCTIONS
1.1 Introduction
Congratulations on your purchase of the KERR SCOTTY Wood Furnace.
Developed in Atlantic Canada, this KERR Furnace has been designed to allow
you to heat your home with wood, one of North America’s most abundant fuels.
Designed with you in mind, the KERR SCOTTY Wood Furnace will provide you
with many years of safe, efficient central heating.
To ensure you have a clear understanding of the operating procedures of this
furnace, please take the time to read the remainder of this section on operating
procedures. If you have any questions, your KERR DEALER will be happy to
answer them for you.
1.2 Wood-Burning
The SCOTTY Wood Furnace will burn most wood fuels, however it is
recommended that only dry, seasoned hardwood be used as much as possible
since it affords cleaner, safer and more efficient operation. Burning seasoned
hardwood will leave less ash, soot and creosote residue and will require fueling
less often. Use smaller loads of wood on warmer days.
WARNING: DO NOT use chemicals or fluids to start the fire or during operation.
DO NOT burn driftwood or manufactured logs (compressed wood).
Before adding fuel to an existing fire turn up the thermostat for about five minutes
or lift damper chain to hold damper fully open for about one minute before
opening the loading door. This action will allow residual smoke to clear from the
combustion chamber and reduce smoke entering the basement during refueling.
Twice daily refueling may be sufficient in modern well-insulated homes.
However, KERR recommends that small fuel loads be added morning, noon and
early evening and late evening, rather than large quantities infrequently. A small
intense fire will burn more efficiently than a large smoldering fire in the SCOTTY
Wood Furnace and will produce less creosote.
When refueling the SCOTTY, the remaining coals should be raked to the front of
the combustion chamber before adding any new fuel. Place the fresh supply of
wood to the rear of the combustion chamber. This gives more of an even cigar
type fuel burn, rather than a large hot fire to a slow amber fire. This will help
create a more even and efficient burn. The SCOTTY owner should attempt to
gauge fuel quantities with outdoor temperatures; a little practice will provide
greater satisfaction and efficiency.
WARNING: This furnace is not to be used with an automatic stoker.
Keep firing door tightly closed and maintain door seal in good condition.

IN CASE A SERIOUS CREOSOTE FIRE BEGINS:
a) Close the damper door by disconnecting chain
b) Close all draft regulators
c) Throw ½ lb of coarse or table salt on the fire and close door immediately.
d) Call the FIRE DEPARTMENT at once!
Have a firmly established Emergency Procedure in place for the handling of a
flue fire.
CREOSOTE
Wood combustion is never 100% complete. Wood smoke always contains some
unburned gases and a mixture of unburned tar-like liquids. A percentage of
these materials will condense out on any cool surface, leaving a dark brown or
black substance with an unpleasant acrid odour. This substance is commonly
called creosote.
These wood gases condense out on cool surfaces such as a cold chimney or a
long smoke pipe; they retain large amounts of water and will be very fluid. At
higher temperatures the condensed creosote will resemble tar (thick and tacky).
Creosote generation is highest during low heat outputs common with long
smoldering burns. Creosote generation is lowest during high heat outputs
common with intense fires. It is recommended that a small intense fire be used
for best results against creosote build up even though the wood furnace will
require refueling more often.
Creosote generation is also higher when burning green wood. The moisture in
the green wood absorbs the heat from the fire, cooling the fire below the point at
which the creosote can be consumed. The low temperature smoke is then
further cooled in the upper furnace chambers’ smoke pipe and chimney allowing
large amounts of creosote to form.
To reduce creosote build-up during periods of low heat requirements (i.e Spring
and Fall) it is recommended to fuel the wood furnace with smaller quantities of
smaller diameter logs. Matching fuel loads and heat requirements will generally
result in cleaner combustion and higher efficiency.

1.3 Storage of Wood
Once cut, green wood dries (or seasons), quickly at first and then at a slower and
slower rate. When the wood has been cut to the proper length and split, it should
be piled outside during the summer months. Place two poles on the ground to
serve as rails to keep the firewood off the moist ground. Stack the wood so that
both ends of the logs are exposed to the air if space is available, since more
drying occurs through the cut ends than through the sides. This is true even with
wood that has been split. The woodpile should be under cover so that it will not
absorb moisture from the rain and snow before it is used, but still open on the
sides and ends to the drying effect of the wind and sun. Store wood in neat, well-
supported piles.
1.4 Maximum Solid-Fuel Charge
The maximum level for a solid-fuel charge is the middle of the loading door, or
the level of the handle. DO NOT OVERFILL.
The KERR SCOTTY Wood Furnace will accept whole or split logs up to 27 in.
(686 mm) long, but a 24 in (610 mm) log length is recommended for convenience
and ease in handling.
Maximum damper gate opening is 11/16”. Do not tamper or adjust to greater
opening in an attempt to increase fire or over-firing and hazard may result.
1.5 Maintenance
Some regular maintenance is necessary on the KERR SCOTTY furnace. A good
practice is to establish a routine for the storage of fuel, care of the appliance, and
firing techniques.
1.5.1 Cleaning (Fig S102-6)
The KERR SCOTTY Wood Furnace must be cleaned regularly to maintain top
efficiency. The furnace needs cleaning more often when burning green wood, or
during long periods of low fire. When the KERR SCOTTY Wood Furnace is first
installed the furnace heat exchanger should be checked visually from the firebox
and smoke pipe hole every week to determine the rate at which creosote or ash
is accumulating within the furnace. Cleaning should be done whenever there is
more than ¼ inch of build-up on the heat exchanger or 3 inches of ash in the
base. See fig. S102-6

SCOTTY WOOD FURNACE –INSTRUCTION MANUAL
SCOTTY 3/31/2006

CLEANING PROCEDURE:
(1) Make sure fire is completely out and the furnace has cooled.
(2) Remove the smoke pipe located on the rear of the furnace heat
exchanger.
(3) The heat exchanger is now accessible for cleaning.
(4) Use the scraper provided to remove all soot and ash from the furnace heat
exchanger and exposed surfaces.
(5) Scrape all residues in the top heat exchanger towards the front of the
furnace where it will fall into the firebox.
(6) Always check flue pipe for creosote or ash build-up in the pipe and clean if
necessary.
(7) Reinstall smoke pipe making sure that all joints are secured with at least 3
sheet metal screws.
(8) Check chimney cleanout for ash build-up and remove any accumulation.
(9) Residue may be removed from the firebox or left to be burnt during the
next fire. It is good practice to leave a layer of ash approximately one inch
deep in the base of the firebox.
DISPOSAL OF ASHES
Ashes should be placed in a metal container with a tight fitting lid. 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. 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.
WARNING –Ashes usually contain live dormant coals, which may burn for many
hours after a recognizable flame has disappeared. Use extreme caution when
handling and disposing ashes.
IMPORTANT –No other waste shall be placed in this container.
1.5.2 Servicing
The furnace air filter must be checked monthly and replaced each year. Annually
lubricate the blower motor, if it is not permanently lubricated, with 4-6 drops of
SAE-30 oil in each bearing.
CAUTION: Failure to keep air filter clean will result in poor furnace performance
and possible damage to wood furnace heat exchanger.

1.6 Safety
If the furnace overheats due to improper operation the following precautions
should be taken:
(1) DO NOT shut off power. The blower must be kept running to disperse
excessive heat.
(2) Manually close the damper door by unhooking the chain.
(3) Check controls for proper operation before starting a new fire.
WARNING –The maximum opening of the combustion air damper is preset at
the factory. DO NOT adjust the stop or attempt to increase the
combustion air by any means.
1.7 Controls (Fig S102-3)
Thermostat
The primary control is the room thermostat located near the center of the house
on the main floor or near an existing thermostat. The thermostat operates the
damper motor to open and close the damper door thus allowing more or less air
into the combustion area to control the fire.
Fan & Limit
The fan and limit control mounted in the plenum controls the operation of the
circulating blower and prevents the furnace from over-heating. When the air
temperature in the plenum reaches the “ON” set point of the fan switch (usually
140º F (60º C)) the blower starts and runs until the plenum cools to the “OFF” set
point (usually 100º F (38º C)) when the blower is switched off. The limit function
in this control is usually set at (250º F (121º C)) and will override the room
thermostat to close the damper door if the furnace overheats, and will also
prevent the oil furnace from starting.

1.8 Electrical Power Failure
If no one is home during a power failure, the damper will automatically close and
some gravity heating will take place. Combustion air will continue to enter
through the secondary air holes and a fire should be maintained.
IMPORTANT –This furnace is CSA certified for operation under Power Failure
only if the following procedure is followed.
For optimum heating during a power failure follow the procedure listed below:
(1) Manually open the blower compartment access door of the wood
furnace to allow gravity flowing air to all areas. (Check with your
installer)
(2) Place a coin under the damper flap in such a way that it will fall
clear when power is restored.
(3) Maintain a careful watch on the furnace temperature. If it should
exceed 200º F (95º C) close the damper door.
(4) Do not leave the furnace unattended in this position.
(5) Refuel frequently with small load to maintain a small fire at ½
normal maximum volume.
(6) Do not expect to maintain maximum comfort under no power
conditions.
(7) Do not allow anyone who is unfamiliar with the operation of the
furnace to attend it during a power failure.

2.3 Locating the Furnace (Fig S102-2)
The location of the furnace must be as close as possible to the chimney. The
chimney must be approved for wood burning appliances (ULC S629). Keep in
mind also the day-to-day operation, and place for ease of fueling and cleaning.
KERR recommends installation if possible, in a central location in relation to the
outlet registers and the use of large warm air ducts to improve heat distribution
during a power failure.
It is important to provide adequate combustion air to the furnace. It may be
necessary to add a ventilator to an exterior wall of a closed furnace room or an
airtight basement.
The furnace must be installed so that the clearances as shown in Figure S102-1,
or those of local authorities are met. If the furnace must be installed on a
combustible floor, a non-combustible base must be built as shown in Figure
S102-2. Two layers of hollow masonry block (4” thick) are placed at right angles
to each other so that the ventilation holes of one layer are opposite to those of
the other layer. Also there must be a minimum of one layer of fireproof board
and one layer of 26 gauge galvanized metal beneath the masonry blocks. This
base must extend beyond the furnace to a minimum distance of 18 inches (457
mm) in front and 8 inches (204 mm) on all sides.
2.4.1 Combustion Air Supply
Air inlets of at least 200 square inches free area (1.5 in2/1000Btu) must be
provided to the room occupied by the wood fired or oil fired furnace. These fresh
air inlets must provide or allow free access of fresh outside air to the furnace. At
no time or under any circumstances can a wood or oil-burning appliance be
starved of combustion air.
The appliance must at all times be able to maintain the approved stack draft.
The barometric draft regulator must be installed on the furnace smoke pipe in the
same room or at least in such a way that there is unrestricted free passage of air
between the combustion air inlet to the furnace or burner and the barometric draft
regulator.
It is important to provide adequate combustion air to the furnace. It may be
necessary to add a ventilator to an exterior wall of a closed furnace room or an
airtight basement.
Operating a wood or oil fired appliance with inadequate combustion air could be
hazardous.

2.4.2 Flue Pipe and Chimney
The furnace must be located to meet a minimum venting distance needed
between the furnace and the flue. It should also be ducted so that there are a
minimum number of elbows used. The flue pipe must be installed with a gradual
rise of ½” or more per foot from the furnace to the flue.
NEVER ALLOW THE SMOKE PIPE TO RUN DOWNHILL TO THE FLUE!
The smoke pipe and chimney should be at least 7 inches in diameter. The flue
pipe or a chimney may be of different cross-sectional area than that of the
appliance smoke pipe, provided that sufficient draft is available at the appliance.
Space must be provided around the smoke pipe and the back of the furnace to
allow easy access for the purpose of cleaning. Smoke pipes must not be lighter
than 24 gauge black steel. All pipes must be securely fastened with at least 3
sheet metal screws at every joint, and properly supported.
Always meet or exceed flue pipe clearance specifications -18” clearance from
flue pipe to combustibles in all directions.
Connect the furnace only to an approved chimney suitable for solid fuel
appliances and capable of venting the product of combustion. The chimney must
be installed with proper clearances above roof and from adjacent structures and
trees. If a masonry chimney is used it must be in good condition and be
equipped with a tile liner. Flue thimble or flue pipe must not extend into the
chimney flue, as it will reduce the draft.
Connect only to a flue or chimney capable of maintaining a negative draft of .05”
wc at all times and conditions.
WARNING: If this setting is exceeded it could cause a solid fuel fire to burn out
of control.
We recommend that the KERR SCOTTY Wood Furnace be connected to its own
chimney. However, two or more fuel fired appliances, other than fireplaces or
incinerators, may be connected to the same chimney.

SCOTTY WOOD FURNACE –INSTRUCTION MANUAL
SCOTTY 3/31/2006
15
The National Standard of Canada, Installation Code for Solid-Fuel-Burning
Appliances and Equipment, CSA-B365-01 clause 5.2.9 states that:
Two or more appliances shall not be connected to the same chimney flue unless:
a. The appliances are located on the same storey;
b. A negative pressure is maintained at the flue collar of each
appliance;
c. Each appliance is provided with a means to control the rate of flow
of air or flue gases through the appliance combustion and heat
exchanger chambers. Where limitations on flue pressure (draft) are
contained in the manufacturer’s instructions, such means shall be
capable of maintaining at the flue collar, the pressure specified by
the appliance manufacture; NOTE: For the purpose of this Clause,
draft controls include ash pit air control dampers, dampers or draft
slides wherever located, over fire and flue key pipe dampers, and
check draft controls located on or in the flue pipe.
d. The flue pipes of the appliances are connected to a manifold as
close to the chimney as practicable or directly to the chimney in the
following order:
(i) If only solid fuel is used, the flue pipe from the smallest
appliance shall be on top (downstream);
(ii) If different fuels are used as permitted in Clause 5.2.7, the oil
flue pipe shall be on top (downstream); and the solid fuel flue
pipe on the bottom (upstream); and
e. The chimney flue is capable of venting the flue gas by natural draft
when all appliances not interlocked to prevent simultaneous firing
are firing at their maximum rate at the same time.
When installing a wood-burning appliance to an existing chimney carefully
inspect entire chimney for the presence of old inlet holes, which may be
improperly covered by metal caps or other unacceptable means. Fill any
openings with brick and mortar to ensure no hazardous openings exist.

2.5 Clearances (Fig S102-1)
The KERR SCOTTY Wood Furnace is to be installed in accordance with National
Building Code or local regulations. Allowances front and rear must be made for
cleaning and servicing.
NOTE: Regardless of minimum clearances to combustibles for safety reasons, a
minimum clearance of 30 inches (765 mm) should be allowed at the
furnace rear for cleaning (due to length of cleaning rake) and access to
smoke pipe.
Minimum safety clearances to combustibles are:
Front 48” 1220 mm
One Side 6” 155 mm
Other Side (for rear access) 24” 610 mm
Rear (see Note above) 24” 610 mm
Flue Pipe to combustible, other furnace & electrical wiring 18” 457 mm
Wood Furnace Above Plenum and 6’(1.8 m) of duct 6” 153 mm
Supply Duct beyond 6’ 2” 50 mm
Return Duct Plenum and 6’(1.8 m) of duct (Free standing) 6” 150 mm
These clearances will also allow adequate combustion air to reach the furnace.
WARM AIR DUCT & PLENUM CLEARANCES
The following clearances must be observed and must meet all local building,
electrical and fire codes. Follow the National Standard of Canada, Installation
Code for Solid Fuel Burning Appliances and Equipment, CSA-B365-01; the
National Board of Fire Underwriters and in the US the NFPA codes.
The KERR SCOTTY Wood Furnace warm air plenum and first 6 feet (1.8 m) of
warm air supply duct in any direction must be installed observing a minimum of 6
inches (155 mm) clearance from the joists or combustible materials. Beyond the
first 6ft (1.8 m) of supply duct, a 2 inches (55 mm) minimum clearance must be
maintained between the warm air supply ducts and all joists or combustible
material (See Fig. S102-1)
Return air ducts, including main ducts and branch ducts, on solid fuel burning
warm air furnaces shall be installed to provide at least 6 inches (150mm)
clearance to combustible construction for the first 6 feet (1.8 m) away from the
furnace plenum.
It is recommended that a non-combustible rigid board be fastened on the
underside of the floor joists in the area of the ceiling above the furnace, warm air
ducts and smoke pipe.

2.6 Duct Connection
Minimum cross-sectional area of ductwork from furnace should be approximately
180 square inches with equal or larger size for return air.
The furnace must not be installed as a gravity only system as the controls are not
designed for this type of operation.
Approved ductwork configurations can be seen in diagram S102-7.
Prohibited ductwork configurations can be seen in diagram S102-7.
The main supply duct for the stand-alone wood furnace in not allowed to be
located lower than the plenum connection to the furnace. Also no section of the
supply main duct is to have any downward slope, which would drop the main
supply duct more than half of the height of the main supply duct. At least 75% of
all takeoff supplies shall terminate above the main supply duct.
2.7 Free-Standing (Fig S102-4)
The KERR SCOTTY Wood Furnace is designed to be the sole source of central
heating in medium sized, well-insulated houses using an integral blower to
circulate warm air. In this system connect the ductwork, as you would for any
conventional warm air heating system except you use increased clearances.
NOTE: This furnace is not to be connected to ductwork that is still connected to
another furnace.
The wiring diagram for the Scotty is shown in Fig. S102-4.
ALL ELECTRICAL WIRING MUST CONFORM TO NATIONAL AND LOCAL
CODES.

2.8 Control System (Fig S102-5)
The fan and limit control and the damper motor should be located as shown in
Figure S102-3 and S102-5.
The control system serves the following functions:
T822 –Room Thermostat –Wood Furnace
The primary control is the room thermostat located near the center of the house
in the main floor or near an existing thermostat. The thermostat operates the
damper motor to open and close the damper door thus allowing more or less air
into the combustion area to control the fire.
M847 –Damper Motor
The damper door lever should be attached to the damper motor wheel with the
chain included. Be sure the damper door is fully closed and the damper motor is
not powered. Connect the chain to the damper door level and to the bottom hole
in the damper motor wheel. As a final adjustment bend the top chain link slightly
to vary the damper position.
L4064R –Wood Furnace/Limit Control
The fan and limit control mounted in the plenum controls the operation of the
circulating blower and limits the air temperature to prevent the furnace from
overheating.
Note: The fan/limit stand off bracket, provided in the wiring kit must be
installed under the fan/limit control.
Set Points
o “ON” is usually set to 140?F (60°C). It turns on the circulating blower
when the air temperature in the plenum reaches this temperature.
o “OFF” is usually set to 100°F (38°C). It turns off the circulating blower
when the circulating air temperature in the plenum drops to this
temperature.
o “Hi limit” is preset to 250°F (121°C). This will over ride the room
thermostat to close fire damper door if the wood furnace overheats.
ALL ELECTRICAL WIRING MUST CONFIRM TO NATIONAL AND LOCAL
CODES.
