1 SAFETY REGULATIONS
1.1 SAFETY LABELING AND
WARNING SIGNS
The words DANGER, WARNING AND CAUTION are used

these words in the manual as follows:
DANGER
Hazards or unsafe practices that CAN result in death
bodily injury and/or property damage.
CAUTION
Hazards or unsafe practices that CAN result in bodily injury
and/or property damage.
1.2 IMPORTANT INFORMATION
I
Non-observance of the safety regulations outlined in I
this manual will potentially lead to consequences I
resulting in death, serious bodily injury and/or I
property damage, I
a) It is the homeowner's responsibility to engage a
qualified technician for the installation and
subsequent servicing of this furnace;
b) Do not use this furnace if any part of it was under
water, Call a qualified service technician
immediately to assess the damage and to replace
all critical parts that were in contact with water;
c) Do not store gasoline or any other flammable
substances, such as paper, carton, etc, near the
furnace;
d) This furnace is designed for use with #1 or #2
heating oil only, The use of gasoline, motor oil or
any other oil containing gasoline is prohibited;
e) Never block or otherwise obstruct the filter and/or
return air openings;
f) Ask the technician installing your furnace to show
and explain to you the following items:
i) The main disconnect switch;
ii) The shut-off valve on the oil tank;
iii) The oil filter and how to change it (once a
year);
iv) The air filter and how to change it (check
monthly and clean or replace if necessary,)
g) Before calling for service, be sure to have the
information page of your manual close by in
order to be able to provide the contractor with
the required information, such as the model and
serial numbers of the furnace.
Installations and repairs performed by unqualified
persons can result in hazards to them and to others,
Installations must conform to local codes or, in the
absence of same, to codes of the country having
jurisdiction,
The information contained in this manual is intended
for use by a qualified technician, familiar with safety
procedures and who is equipped with the proper
tools and test instruments,
Failure to carefully read and follow all instructions in
this manual can result in death, bodily injury and/or
property damage.
1.3 DETECTION SYSTEMS
It is recommended that carbon monoxide detectors be
installed wherever oil or gas fired heaters are used.
Carbon monoxide can cause bodily harm or death. For
this reason, agency approved carbon monoxide
detectors should be installed in your residence and
properly maintained to warn of dangerously high carbon
monoxide levels.
There are several sources of possible smoke and
flames in a residence. Smoke and flames can cause
bodily harm or death. For this reason, agency approved
smoke detectors should be installed in your residence
and properly maintained, to warn early on, of a
potentially dangerous fire. Also, the house should be
equipped with approved and properly maintained fire
extinguishers.
Your unit is equipped with safety devices that can prevent
it from functioning when anomalies are detected such as
a blocked venting system.
1.4 DANGER OF FREEZING
CAUTION
If your furnace is shut down during the cold weather
season, water pipes may freeze, burst and cause serious
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 required.

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 : Canadian Electrical Code.
or CSA C22.10
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.

air openings in a closet door
¢- >
Only the latest issues of these codes may be used.
2.1 POSITIONING THE FURNACE
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.
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.
