2 INSTALLATION
This furnace is a true multi-position unit, in that it will
function in an upflow, downflow or horizontal configuration
to the left or the right. Only a few modifications are
required during installation to change from one position to
another. The unit is shipped in the upflow configuration
and instructions as to how to change to the other
positions are included in this manual.
The unit is shipped with a burner and its controls. It
requires a 115VAC power supply to the control panel and
thermostat hook-up as shown on the wiring diagram, one
or more oil line connections, suitable ductwork and
connection to a properly sized vent.
All local and national code requirements governing the
installation of oil burning equipment, wiring and the flue
connection MUST be followed. Some of the codes that
may apply are:
CSA B139: Installation code for oil burning
equipment.
ANSI/NFPA 31: Installation of oil burning equipment.
ANSI/NFPA 90B: Warm air heating and air conditioning
systems.
ANSI/NFPA 211: Chimneys, Fireplaces, Vents and solid
fuel burning appliances.
ANSI/NFPA 70: National Electrical Code.
CSA C22.1 or CSA C22.10:
Canadian Electrical Code.
Only the latest issues of these codes may be used.
2.1 POSITIONING THE FURNACE
WARNING
Fire and explosion hazard.
The furnace must be installed in a level position, never
where it will slope toward the front.
Do not store or use gasoline or any other flammable
substances near the furnace.
Non-observance of these instructions will potentially
result in death, bodily injury and/or property damage.
CAUTION
This furnace is not watertight and is not designed for
outdoor installation. It must be installed in such a manner
as to protect its electrical components from water.
Outdoor installation will lead to a hazardous electrical
condition and to premature failure of the equipment.
The minimum clearances from combustible material
for each of the positions are specified in Table 4.
If the furnace is installed in a basement or on a dirt floor,
in a crawl space for example, it is recommended to install
the unit on a cement base 2.5 cm to 5.0 cm (1" to 2")
thick.
The unit must be installed in an area where the ambient
and return air temperatures are above 15°C (60°F). In
addition, the furnace should be installed as closely as
possible to the vent, so that the connections are direct
and kept to a minimum. The heater should also be
located close to the centre of the air distribution system.
2.1.1 Installation in an enclosure
The unit can be installed in an enclosure such as a
closet. However, 2 ventilation openings are required for
combustion air. The openings should be located in front
of the furnace approximately 15 cm (6") above the floor
and 15 cm (6") below the ceiling. Figure 1 indicates the
minimum dimensions required and the location of the
openings.

2.2 CONFIGURATIONS
2.2.1 Upflow Installation
The return air opening may be located on either side of
the furnace. Care should be taken not to damage the
wires inside, while cutting the opening. Install the filter
rack supplied with the unit according to the instructions
provided with it. It is also recommended to install the
blower door before handling or moving the unit. Refer to
Figure 2 for additional details.
