ENVIRONMENTAL HAZARD
Failure to follow this caution may result in
environmental pollution. Remove and recycle all
components or materials (i.e., oi, electrical and
electronic components, insulation, etc.) before
unit final disposal.
1.2 GENERAL
This central heating unit is a true multi-position unit, in that it
can operate in four different configurations, i.e., upflow,
counter flow (downflow), and horizontal (both left-to-right and
right-to-left airflow).

Very few modifications are required during installation, to
change the furnace from one configuration to another. The
furnace is shipped in the upflow configuration; however,
instructions on how to change to the other configurations are
included in this manual.
The furnace is shipped complete with burner and controls. It
requires a 115VAC line voltage connection to the control
panel, thermostat hook-up as shown on the wiring diagram,
one or more oil line connections, suitable ductwork and
connection to a properly sized vent.
The air handling capacity of this furnace is designed for
cooling as weil. Please refer to Table 6 for the expected
airflow at various external static pressures.
1.3 LOCATION
The unit must be installed in a location where the ambient
and return air temperature is over 15°C (60°F).
y Wa GU
This furnace is not watertight and is not
designed for outdoor installation. This
furnace shall be installed in such a manner as
to protect the electrical components from
water. Outdoor installation will lead to a
hazardous” electrical condition and_ to
premature furnace failure.
if this furnace is installed in an attic, it is important
to keep insulation at least 0.3 m (12") away from
any furnace openings. Some types of insulating
material may be combustible.
This furnace is approved for reduced clearances to
combustible construction. Therefore, it may be installed in a
closet or similar enclosure. As this unit may be installed as
an upflow, counter flow, or horizontal furnace, it may be
located in a basement, on the same level as the area to be
heated, suspended, or in a crawispace. In any case, the unit
should always be installed level.
In a basement, or when installed on the floor (as in a
crawlspace), it is recommended that the unit be installed on
a concrete pad thatis 2.5 cm to 5.0 cm (1" to 2") thick.
When installed in the counter flow position, this furnace must
not be installed on combustible flooring, unless the approved
sub-base is used (Model # DFB-101). Since the flue pipe is
in counter flow position, be sure that the clearances from the
flue pipe to combustible construction are maintained. Also, it
is recommended to use the flue pipe protection kit FPG-101
or FPG-102. Please refer to the Figure 1 and the installation
instructions included with the kit.
Figure 1: Counterflow position, flue pipe
protection FPG
FPG
DNS-0278 Rev. A
When installed in an horizontal position, the furnace may be
suspended by using an angle iron frame, as long as the total
weight of both the furnace and the frame are included in the
calculations. Other methods of suspension are acceptabie.
When installed in the horizontal position, this furnace must
not be installed on combustible flooring, unless the approved
sub-base is used (Model # HFB-101).
The required minimum clearances for this furnace in all
positions are specified in Tables 7 and 8.
The furnace should be located as closely as possible to the
chimney or vent in order to keep vent connections short and
direct. The furnace should also be located near the centre of
the air distribution system.
1.3.1 Air for combustion and ventilation
Please refer to the CAN/CSA-B139 Installation Code for
complete regulations and for guidance on_ retrofit
applications.
This furnace should be installed in a location in which the
facilities for ventilation permit satisfactory combustion of oil,
proper venting and the maintenance of ambient
temperatures at safe limits under normal conditions of use.
The location should not interfere with the proper circulation of
air within the confined space.
When this furnace is installed in a closet or similar enclosure,
2 ventilation openings are required for combustion air. The
openings should be located about 15.2 cm (6") from the top
and the bottom of the enclosure at the front of the furnace.
Table 1 indicates the minimum dimensions required for these
ventilation openings.
Table 1: Minimum dimensions required in ventilation
openings
Input
(BTU/h) Width Height
75,000 — 105,000 45.72 cm (18") 20.32 cm (8")
120,000 — 155,000 50.80 cm (20") 25.40 cm (10")

WMT e
Do not block the combustion air openings in
the furnace. Any blockage will result in
improper combustion and may result in a fire
hazard and/or cause bodily harm.
Return air grils and warm air registers must not be
obstructed.
For chimney application, the barometric draft regulator
included with the furnace, shall be installed in the same room
or enclosure as the furnace, in such a manner as to prevent
any difference in pressure between the regulator and the
combustion air supply.
Air requirements for the operation of exhaust fans, kitchen
ventilation systems, clothes dryers, and fireplaces shall be
considered in determining the adequacy of the space to
provide combustion air requirements.
In unconfined spaces, in buildings of conventional frame,
brick or stone construction, infiltration may be adequate to
provide air for combustion, ventilation and dilution of flue
gases. This determination must be made on an individual
installation basis and must take into consideration the overall
volume of the unconfined space, the number of windows and
ventilation openings, the number of doors to the outside,
internal doors which can close off the unconfined space and
the overall air tightness of the building construction.
Many new buildings and homes (and older ones that have
been weatherized must be considered as being tight
construction and, therefore, infiltration will not be sufficient to
supply the necessary air for combustion and ventilation.
A building can be considered as being of tight construction
when:
a. Walls and ceilings exposed to the outside have a
continuous water vapour retarder with a rating of one
perm or less, openings have gaskets or are sealed
and/or;
b. Weather-siripping has been added on operable windows
and doors, and/or;
c. Caulking or sealant has been applied to areas such as
joints around window and doorframes, between sole
plates and floors, between wall-ceiling joints, between
wall panels, at penetrations for plumbing, electrical and
fuel lines and at other openings.
1.3.2 Duct recommendations
WMT GUI
When ducting supplies air to a space other
than where the furnace is located, the return
air must be sealed and also be directed to the
space other than where the furnace is located.
Incorrect ductwork termination and sealing
will create a hazardous condition that can
lead to bodily harm.
IMPORTANT: The dampers should be adequate to
prevent cooled air from entering the furnace, and if
manually operated, must be equipped with the means
to prevent operation of either the cooling unit or the
furnace, unless the damper is in the full cool or heat
position.
NOTE: THE BACK SHOULD NOT BE CUT OUT FOR
RETURN AIR DUCTING
The proper sizing of warm air ducts is necessary to ensure
satisfactory furnace operation. Ductwork should be in
accordance with the latest editions of NFPA-90A (Installation
of Air Conditioning and Ventilating Systems) and NFPA-90B
(Warm Air Heating and Air Conditioning Systems) or
Canadian equivalent.
The supply ductwork should be attached to the flanged
opening provided at the discharge end of the furnace. See
Figures 9 and 10, for the dimensions of this opening.
Knockouts are provided on both sides of the furnace to cut
the required size of opening for the installation of the return
air ductwork. This can be done on either the right or the left
side of the furnace. See Table 2 for location and dimensions.
Also, there is provision on this furnace for a bottom return air
duct. Knockouts are provided in the floor of the furnace to
facilitate the cut-out requirement for the air filter rack and
return ductwork. (We recommend the use of this opening for
horizontal and counterflow installations).
The following recommendations should be followed when
installing ductwork:
a. Install locking type dampers in all branches of the
individual ducts to facilitate balancing the system.
Dampers should be adjusted such a way as to ensure
the proper static pressure at the outlet of the furnace;
b. A flexible duct connector of non-combustible material
should be installed at the unit on both the supply and
return air side. In applications where an extremely quiet
operation is necessary, the first 3 m (10°) of supply and
return ducts should be internally lined with acoustical
material (if possible);
c. In cases where the return air grille is located close to the
fan inlet, there should be at least one 90° turn between
fan inlet and grille. Further reduction in sound level can
be accomplished by installing acoustical turning vanes
or lining the duct as described in item b. above;
d. When a single air grille is used, the duct between grille
and furnace must be the same size as the return air
opening in the furnace.
When installing the furnace with cooling equipment for year
round operation, the following recommendations must be
followed for tandem or parallel air flow:
a. On tandem airflow applications, the coil is mounted after
the furnace in an enclosure in the supply air stream. The
furnace blower is used for both heating and cooling
airflow;

b. On parallel airflow installation, dampers must be
provided to direct air over the furnace heat exchanger
when heat is desired and over the cooling coil when
cooling is desired.
The coil MUST be installed on the air discharge
side of the furnace. Under no circumstances
should the airflow be such that cooled,
conditioned air is allowed to pass over the furnace
heat exchanger. This will cause condensation in
the heat exchanger and possible failure of same,
which could result in a fire hazard and/or other
hazardous conditions that may lead to bodily
harm. Heat exchanger failure due to improper
installation may not be covered by the warranty.
1.3.3 Venting instructions
Venting of the furnace must be to the outside and in
accordance with local codes and/or requirements of local
authorities.
OIL FIRED APPLIANCES INSTALLED WITH CHIMNEY
SHALL BE CONNECTED TO FLUES HAVING SUFFICIENT
DRAFT AT ALL TIMES TO ENSURE SAFE AND PROPER
OPERATION OF THE APPLIANCE.
For additional venting information please refer to ANSI/NFPA
211 Chimneys, Fireplaces, Vents and Solid Fuel Burning
Appliances and/or the CSA B139 Installation Code.
This furnace is certified for use with a Type “L” vent

pipe clearance knockout in the front top or side panel should
be removed. Install the flue elbow so that it exits the furnace
cabinet through that opening.
Pre-installation vent system inspection
Before this furnace is installed, it is strongly recommended
that any existing vent system be completely inspected.
On any chimney or vent, this should include the following:
a. Inspection for any deterioration in the chimney or vent. If
deterioration is discovered, the chimney must be
repaired or the vent replaced;
b. Inspection to ascertain that the vent system is clear and
free of obstructions. Any blockages must be removed
before installing this furnace;
c. Cleaning the chimney or vent if previously used for
venting a solid fuel burning appliance or fireplace;
d. Confirming that all unused chimney or vent connections
are properly sealed;
e. Verification that the chimney is properly lined and sized
per the applicable codes. (Please refer to list of codes in
Part 1)
Masonry Chimneys
This furnace may be vented into an existing masonry
chimney. However, it must not be vented into a chimney
servicing a solid fuel-burning appliance. Before venting this
furnace into a chimney, the chimney must be checked for
deterioration and repaired if necessary. The chimney must
be properly lined and sized per local and/or national codes.
If the furnace is vented into a common chimney, the chimney
must be of sufficient area to accommodate the total flue
products of all appliances vented into the chimney.
The following requirements are provided for a safe venting
system:
a. Ensure that the chimney flue is clear of any dirt or
debris;
b. Ensure that the chimney is not servicing an open
fireplace;
c. Never reduce the pipe size below the outlet size of the
furnace;
d. All pipes should be supported, using the proper clamps
and/or straps. These supports should be installed at
least every 4 feet;
e. All horizontal runs of pipe should have at least 6.4 mm
(1/4”) of upward slope per 0.3 m (1');
f. All runs of pipe should be as short as possible with as
few turns as possible;
g. Seams should be tightly joined and checked for leaks;
h. The flue pipe must not extend into the chimney but be
flush with the inside wall:
i. The chimney must extend 0.9 m (3') above the highest
point where it passes through a roof of a building and at
least 0.6 m (2') higher than any portion of a building
within a horizontal distance of 3 m (10'). It shall also be
extended at least 1.45 m (5') above the highest
connected equipment flue collar;
j. Check local codes for any variances.
Factory Built Chimneys
Approved factory built chimneys may be used. Refer to
chimney manufacturer’s instructions for proper installation.
1.3.4 Draft Regulator (Chimney venting)
The draft regulator supplied with the furnace must be used
for proper functioning. Installation instructions are included
with the control.
1.3.5 Blocked vent shut-off (BVSO)
For chimney venting
TNE CURT
It is imperative that this device be installed by
a qualified agency.
This device is designed to detect the insufficient evacuation
of combustion gases in the event of a vent blockage. In such
a case the thermal switch will shut down the oil burner. The
device will then need to be re-armed MANUALLY.

Poisonous carbon monoxide gas hazard.
Install the evaporator coil on the supply side of the
furnace ducting ONLY.
An evaporator coil installed on the return air side
of the ducting can cause condensation to form
inside the heat exchanger, resulting in heat
exchanger failure. This in turn can result in death,
bodily injury
Use only copper wire for 115V supply service to the unit.
Metallic conduit (where required/used) may terminate at the
side panel of the unit. It is not necessary to extend the
conduit inside the unit from the side panel to the control box.
When replacing any original furnace wiring, use only 105°C,
16 AWG copper wire.
Instructions for wiring the thermostat are provided with the
thermostat (field supplied). Wire the connections to the 24-
No minimum clearance is required between the bottom of the
coil drain pan and the top of the heat exchanger. If a heat
pump is installed, a “dual-energy” thermostat, or other
control is required, in order to prevent the simultaneous
operation of the furnace and the heat pump. It also prevents
a direct transition from heating by way of the heat pump to
heating with oil. Refer to the thermostat instructions or those
of another control used for the proper wiring.
If a coil blower compartment is used, install air tight,
motorized and automatic air dampers. Cold air coming from
the coil and passing across the furnace can cause
condensation and shorten the life of the heat exchanger.
1.3.11. Horizontal or downflow installation
1. On horizontal installations, determine which “side” will
become the “top”, when the unit is laid down. Remove
the flue pipe clearance knockout from the top front of
that side panel. Install the flue elbow so that it exits the
cabinet of the furnace through that opening;
8

On counterflow Installations, the flue pipe must exit the
cabinet through one of the side panel openings (as
above), then extended up the side of the furnace.
Ensure that adequate clearances to combustibles are
observed. It may be necessary to install a sheet-metal
shield on an adjacent wall to prevent any possibility of a
fire hazard;
Remove the burner by loosening the mounting nuts and
turn the oil burner slightly counter clockwise to unlock
the burner flange. Avoid putting undue strain on burner
wiring. It may be necessary to disconnect the burner
wiring in some cases;
To reinstall the burner, insert the burner and the burner
flange screws and turn the burner clockwise to lock it;
then tighten the nuts.
Remove the burner by loosening the mounting nuts and
turn the oil burner slightly in the opposite direction
clockwise to unlock the flange of the burner. Avoid
unnecessary stress to the spinning of the burner. (It may
be necessary to disconnect the electric burner cords in
some cases).

Do not use this furnace as a construction
heater. Use of this furnace as a construction
heater exposes it to abnormal conditions,
contaminated combustion air and the lack of
air filters. Failure to follow this warning can
lead to premature furnace failure and/or vent
failure, which could result in a fire hazard
and/or bodily harm.

ye 7 \U ce)
2. The proper smoke number, as established by way of
engineering tests, is between 0 and 1. This degree of
smoke emission is commonly referred to as a “trace”. It
is recommended that a Bacharach True Spot Smoke
Test kit or equivalent be used;
3. On chimney installations only, a barometric draft
regulator (supplied with the furnace) must be installed as
closely to the breech of the furnace as possible, in order
to ensure proper draft through the furnace. The
barometric damper must be mounted with the hinge pins
in a horizontal position and the face of the damper
vertical for proper functioning, (see instructions included
with damper). After the furnace has been firing for at
least five minutes, the draft regulator should be set to
between -0.025" W.C. and -0.035" W.C.:
4. The overfire pressure that is taken through the
observation door located in the centre of the front panel
above the burner is a measurement that is necessary to
determine if there is a blockage in the heat exchanger or
the flue pipe. Please refer to the Technical
Specifications in this manual for overfire pressure
values. A high pressure condition may be caused by
excessive combustion air due to the air band being too
Do not tamper with the unit or its controls. Call a
qualified service technician.
2.2 COMBUSTION CHECK
In order to obtain optimum performance from the oil burner,
the following set-up procedures must be followed by referring
to the Technical Specifications, Table 5 in this manual:
1. A test kit to measure the smoke, flue draft and over-fire
pressure should be used in order to obtain the proper air
band setting. Although all of the above measurements
are required for optimum set up and efficiency, the most
important reading that must be taken is the smoke
number in the flue pipe, downstream from the regulator:
wide open or a lack of flue draft (chimney effect) or
some other blockage, such as soot in the secondary
section of the heat exchanger or the use of an oversize
nozzle input or high pressure pump;
CO, and flue temperature instruments will enable you to
obtain the data that are required to determine the true
efficiency of the furnace. Although this information is
nice to have, it is not essential in the basic set up of the
furnace. The proper procedure for performing this
operation is as follows:
a. Start the appliance and proceed with the smoke test
at the test port provided on the BREECH PLATE (of
the Sealed Combustion System) or on the flue pipe
just before the draft regulator (chimney application),
9

and adjust the burner to a setting of between a
“trace” and #1 smoke after 5 to 10 minutes of
operation;
Take a CO, reading and mark it down;
Open the burner air shutter to get 1.5% COs less
than the previous reading noted in b. above and
take a smoke test on this condition;
d. The new smoke reading should give you a ZERO
smoke reading.
6. A 10-micron (or less) oil filter should be installed as
closely to the burner as possible with all oil burners, but
it is essential for burners with a low firing rate. We
recommend the use of a low pressure drop oil filter with
a capacity greater than that of the fuel pump;
7. On a new installation, the air trapped in the oil line
leading from the tank to the nozzle must be thoroughly
purged in order to prevent excessive after drip. The oil
pump is equipped with a special fitting that facilitates the
purging of any air between it and the tank. The proper
procedure for performing this operation is as follows:
a. Place a piece of 1/4” diameter clear plastic tubing
over the purge fitting on the oil pump;
b. Start the oil burner, then open the purge fitting and
allow the burner to run until the purge tube is
completely free of air bubbles;
c. At this point tighten the purge fitting, which will allow
the oil to run to the nozzle and fire the burner. If the
purging takes longer than 15 seconds and no flame
has been established the burner will stop. Push the
reset button on top of the Primary Control to restart
the burner.
For detailed information on the operation of the Primary
Control please refer to the instructions included with the
furnace or the burner.
8. After all the set up procedures mentioned above have
been completed, the burner should be fired and an
inspection mirror should be used to observe the flame
pattern at the tip of the nozzle. Any irregularities such as
burning to one side or pulsating flame patterns should
be corrected by changing the nozzle.
2.3 SUPPLY AIR ADJUSTMENTS
(4-SPEED MOTORS)
On units equipped with 4-speed blower motors, the supply
air must be adjusted based on heating/air conditioning output
and the static pressure of the duct system. For the desired
air flow please refer to the following table as well as the air
flow Table 6 based on static pressure in the Technical
Specifications, Table 5 of this manual.

To effect the adjustment, the RED and BLUE wires can be
changed on the motor. Also, please refer to the position of
the wires on the electronic board of the unit and consult the
wiring diagrams. If the heating and the air conditioning
speeds are the same, the RED wire must be moved to
“JNUSED LEADS” on the electronic board and the jumper
provided with the BLUE wire must be used between the
“HEAT” and “COOL” terminals.
The blower start/stop delays can be adjusted by positioning
the DIP switches on the electronic board as shown on the
following figures.
Figure 8: Blower Start/Stop delays

2.4 LIMIT CONTROL CHECK
After the furnace has been in operation for at least 15
minutes, restrict the return air supply by blocking the filters or
closing the return registers and allow the furnace to shut
down on High Limit. The burner will shut OFF but the main
blower should continue to run.
Remove the restriction and the burner should come back on
in a few minutes.
2.5 YEAR ROUND AIR CONDITIONING
The furnace is designed for use in conjunction with cooling
equipment, to provide year round air conditioning. The
blower has been sized for both heating and cooling;
however, the fan motor speed may need to be changed to
obtain the necessary cooling airflow.
2.6 HEATING
The blower speed is factory set to deliver the required airflow
at normal duct static pressure.
2.7 COOLING
The blower speed may be adjusted in the field to deliver the
required airflow for cooling applications, as outlined in Table
6.

2.8 CONSTANT BLOWER SWITCH
This furnace is equipped with a constant low speed blower
option. Whenever the room thermostat is not calling for
heating or cooling, the blower will run on low speed in order
to provide air circulation. If this constant blower option is not
desired, the rocker switch on the side of the control box can
be used to turn it off.
PART 3 - MAINTENANCE
This furnace should never be operated without an air filter.
Disposable filters should be replaced at least once a year. If
the furnace is equipped to provide cooling as well, filters
should be replaced a minimum of twice a year.
Before performing any service functions, make sure that all
utilities are turned “OFF” upstream from the appliance,
unless operations specifically require the power to be on.
Failure to comply with this warning will cause a fire hazard
and/or bodily harm.
3.2 BLOWER REMOVAL
Be sure that the blower is adequately supported when sliding
it off the mounting rails, especially in the horizontal or
counter flow positions, in order to prevent dropping it and
injuring yourself or damaging the blower!
For optimal performance, the oil burner nozzle should be
replaced at least once a year. Contact a qualified service
technician for the installation. The procedure for nozzle
installation and/or replacement is outlined in the oil burner
