2 INSTALLATION

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.

2.2 ELECTRICAL

SYSTEM

CAUTION

The exterior of the unit must have an uninterrupted ground
to minimize the risk of bodily harm, if ever an electrical
problem develops. A green ground screw is supplied with
the control box for that purpose.

The appliance must be installed in accordance with the
current ANSI/NFPA 70 National Electrical Code, CSA
C22.1 Canadian Electrical Code Part 1 and/or local codes.

The control system depends on the correct polarity of the
power supply. Connect “HOT” wire (H) and “NEUTRAL”
wire (N) as shown in Figures 3 and 4, p. 17 and 18.

A separate line voltage supply should be used, with fused
disconnect switch or circuit breaker, between the main
power panel and the unit.

Only copper wire may be used for the 115V circuit on this
unit. If wires need to be changed, the replacements must
have the same temperature resistance as the originals.

2.3

INSTALLATION OF THE BURNER

Also refer to the burner manufacturer’s instructions.

1. Position the mounting gasket between the mounting

flange and the burner mounting plate. Align the holes
in the burner mounting plate with the studs on the
mounting flange and bolt securely in place.

2. Remove the burner drawer assembly or the air tube

assembly;

3. Install the nozzle (refer to Technical Specifications,

p.13);

4. Check the electrode settings;

5. Make the electrical connections;

6. Complete oil line connections.

2.3.1

OZZLES

The burner comes equipped with an appropriate nozzle.
However, if another size or a replacement nozzle is
required, use the manufacturer’s recommended spray
angle and type a shown in Table 1 and based on a pump
pressure of 100 psi.

Always select nozzle sizes by working back from the
desired flow rate at operating pressure and not the nozzle
marking.

2.3.2

IR AND

URBULATOR

ETTINGS

Before starting the burner for the first time, adjust the air
and turbulator settings to those listed in this manual. Once
the burner becomes operational, final adjustments will be
required. Refer to section 3 of this manual.
