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.
445 01 4O94 O4 3

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 welt. Please refer to Table 4, p. 14 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).
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.
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.
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 FPG-102. Please refer to the above drawing and the
installation instructions included with the kit.
DNS-0278 Rev. A
When installed in a horizontal position, the furnace may be
suspended by using an angle iron frame, as tong 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 (Model # HFB-101).
The required minimum clearances for this furnace in all
positions are specified in Tables 5.1 and 5.2, p. 15 and
16.
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.

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.
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-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 walt-ceiling joints, between
wall panels, at penetrations for plumbing, electrical and
fuel lines and at other openings.
1.3.2 Duct recommendations
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.
Return air grilles and warm air registers must not be
obstructed.
CAUTION I
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 I
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 7.1 & 7.2, p.15 and 16, 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, p. 9, 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;
I
445 01 4O94 O4 5

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

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.
6 445 01 4094 04
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

1.3.10 Air Conditioner (or Heat Pump)
An air conditioning coil may be installed on the supply air
side ONLY.
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
The unit cabinet must have an uninterrupted or
unbroken electrical ground to minimize personal
injury if an electrical fault should occur. A green
ground screw is provided in the control box for
this connection.
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-
volt terminal board on the primary relay as shown in Figures
8.1 to 8.2, p. 17 & 18.
No minimum clearance is required between the bottom of the
coil drain pan and the top of the heat exchanger. Ifa 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. Italso 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;
