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.
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: Canadian Electrical Code.
or CSA C22.10:
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 9.
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.
