2.0 INSTALLATION
2.1 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 an 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.

2.3 SAFETY RULES
Your unit is built to provide many years of safe and
dependable service, provided it is properly installed and
maintained. However, abuse and/or improper use can
shorten the life of the unit and create hazards for you, the
owner.
2.3.1 Detector
a. The U.S. Consumer Product Safety Commission
recommends that users of oil-burning appliances install
carbon monoxide detectors. There can be various
sources of carbon monoxide in a building or dwelling.
The sources could be gas-fired clothes dryers, gas
cooking stoves, water heaters, furnaces, gas-fired
fireplaces, wood fireplaces, and several other items.
Carbon monoxide can cause serious bodily injury and/or
death. Therefore, to help alert people to potentially
dangerous carbon monoxide levels, you should have
carbon monoxide detectors listed by a nationally
recognised agency (ex. Underwriters Laboratories or
International Approval Services) installed and
maintained in the building or dwelling (see Note below).
b. There can be numerous sources of fire or smoke in a
building or dwelling. Fire or smoke can cause serious
bodily injury, death, and/or property damage. Therefore,
in order to alert people to potentially dangerous fire or
smoke, you should have fire and smoke detectors listed
by Underwriters Laboratories installed and maintained in
the building or dwelling (see Note below).
NOTE: The manufacturer of your furnace does not test any
detectors and makes no representations regarding any brand
or type of detector.
CAUTION
Ensure that the area around the combustion air intake is
free of snow, ice and debris.
2.3.2 Freezing temperatures and your building
WARNING
FREEZING TEMPERATURE WARNING
Turn off water supply.
If your heater remains shut off during cold weather, the
water pipes could freeze and burst, resulting in serious
water damage.
If the structure is unattended during cold weather you should
take the following precautions:
a. Turn off main water supply into the structure and drain
the water lines if possible. Open faucets in appropriate
areas;
b. Have someone check the structure frequently during
cold weather to make sure it is warm enough to prevent
pipes from freezing. Contact a qualified service agency,
if required.

2.4 LOCATION
5
CAUTION
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 hazardous
electrical conditions and to premature furnace failure.
CAUTION
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.
The unit must be installed in a location where the ambient
and return air temperature is over 15°C (60°F).
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 crawlspace. 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 that is 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 FPF-102. Please refer to the Figure 1 and the installation
instructions included with the kit.
Figure 1 : Counterflow position, flue pipe protection
When installed in a 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 acceptable.
When installed in the horizontal position, this furnace must
not be installed on combustible flooring, unless the approved
sub-base is used (# DFB-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.
2.4.1 Air for combustion and ventilation
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.
Refer to the CAN/CSA-B139 installation code for complete
regulations, and for guidance on retrofit applications.
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 each
of these two 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")
WARNING
DNS-0278 Rev. A
FPG-101 /
FPG-102
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.
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-stripping 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.
2.4.2 Duct recommendations
6
WARNING
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.
CAUTION
Return air grilles and warm air registers must not be
obstructed.
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 90oturn 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:
WARNING
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.
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.
2.4.3 Venting instructions (chimney installation)
The furnace must be vented to the outside, in accordance
with local codes and other authorities having jurisdiction.
CAUTION
Oil fired appliances must be connected to flues having
sufficient draft at all times to ensure safe and proper
combustion.
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 uses with a Type “L” vent
(maximum flue gas temperature 302°C (575°F)). The flue
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 1.2)
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.
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 20 mm of
upward slope per 1 m (1/4” per 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 1.5 m (5') above the highest

2.4.9 Air Conditioner (or Heat Pump)
An air conditioning coil may be installed on the supply air
side ONLY.
WARNING
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.
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.

10
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.
2.4.10 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;
2. 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;
3. Remove the burner. If it’s a Beckett burner models,
loose the mounting nuts and turn the oil burner slightly
counter clockwise to unlock the burner flange. For the
Riello burner models, unscrew the mounting nuts. Avoid
putting undue strain on burner wiring. It may be
necessary to disconnect the burner wiring in some
cases;
4. To reinstall the Beckett burner, insert the burner in the
burner flange bolts and turn the burner clockwise to lock
it; then tighten the nuts.
IMPORTANT: The burner must always be installed in the
upright position with the ignition control on top.
3.0 OPERATION
3.1 SUPPLY AIR ADJUSTMENTS
This unit is 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 Table 3 and 4
as well as the air flow Table 6 based on static pressure in the
Technical Specifications, Table 5, of this manual.

To start the unit, turn the main electrical switch on.

11
CAUTION
Do not tamper with the unit or its controls. Call a
qualified service technician.
3.3 PURGING THE OIL LINE
1. 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;
2. 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.
3.4 COMBUSTION CHECK
IMPORTANT: The heat exchanger metal surfaces may
have oil and the baffle insulation also contains binders.
These products will burn or evaporate when the unit
operates for the first time. Because of this, the smoke
reading may be inexact during the first minutes of operation.
Therefore, the unit must operate during at least 60 minutes
before taking any readings to adjust the combustion quality.
Let the unit cool down before making any adjustments.
IMPORTANT: The combustion check verification MUST be
performed after the nozzle replacement or the burner
cleaning. After these manipulations, the combustion
parameters are necessarily modified. Refer also to the
burner instruction manual.
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;
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. Follow the next steps to do the combustion check
verification:
a. Drill a minimum proper diameter (about 9/32”) test
hole in the flue pipe, approximately 18 inches from
the furnace breech;
b. From a cold start, let the unit operate for about 5
minutes;
c. Set the burner air setting until you have between 0
and 1 on the Bacharach Scale (or a “trace”);
d. Take a CO2sample at the same test location where
the smoke reading was taken and make note of it;
e. Adjust the burner air setting to obtain a CO2 reading
1.5% lower (or a O2reading 2.0% higher) than the
reading associated with the “trace” of smoke;
f. This method of adjusting the burner will result in
clean combustion (Bacharach smoke scale between
0 and a trace) and ensure the proper functioning of
the system.
4. A barometric draft regulator, supplied with the furnace,
must be installed, 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.;
5. The over fire 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 over fire pressure
values. A high pressure condition may be caused by
excessive combustion air due to the air band being too
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;
6. 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.
3.5 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.
3.6 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.
3.7 HEATING
The blower speed is factory set to deliver the required airflow
at normal duct static pressure.
3.8 COOLING
The blower speed may be adjusted in the field to deliver the
required airflow for cooling applications, as outlined in Table
4.
3.9 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.
4.0 MAINTENANCE
12
