DANGER OF FREEZING
CAUTION
If your furnace is shut down during the cold weather
season, water pipes may freeze, burst and cause se-
rious water damage. Turn off the water supply and
bleed the pipes.
If the heater is left unattended during the cold weather
season, take the following precautions:
a) Close the main water valve in the house and purge
the pipes if possible. Open all the faucets in the
house;
b) Ask someone to frequently check the house during
the cold weather season to make sure that there is
sufficient heat to prevent the pipes from freezing.
Tell this person to call an emergency number if re-
quired.

INSTALLATION
The unit is shipped with a burner and its controls. It re-
quires 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 con-
nection 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 equip-
ment;
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 shall be used.
2.1
POSITIONING THE FURNACE
WARNING
F
IRE 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 poten-
tially 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 man-
ner 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 10.
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 lo-
cated 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, two ventilation openings are required for com-
bustion 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.
