Nozzles
The burner is equipped with an appropriate nozzle. However, if
another size nozzle, or replacement nozzle is required, use the
manufacturer's nozzle data recommended in Tables 4.1 to 4.5. Note
that all nozzle-marked sizes are based on a pump pressure of 100 psi.
Always select nozzle sizes by working back from the actual desired
flow rate at operating pressure, and not by the nozzle marking.
Fuel supply system
Fuel Specifications
Use No.1 or No.2 Heating Oil (ASTM D396) or in
Canada, use No.1 or No.2 Furnace Oil.
Before starting the burner be sure the fuel tank is filled with clean oil.
IMPORTANT
When using nozzle sizes of less than 0.75 USGPH, the
Installation Code for oil burning equipment requires the
installation of a 10 micron (or less) filter in the fuel oil
line. This practice must be followed in order to keep the
lifetime heat exchanger warranty intact.
WARNING
!
Fire and explosion hazard.
Use only approved heating type oil in this furnace.
DO NOT USE waste oil, used motor oil, gasoline or
kerosene.
Use of these will result in death, personal injury
and/or property damage.
NOTE: You may notice a slight odour the first time your
furnace is operated. This will soon disappear. It is only
oil used on certain parts during manufacturing.
WARNING
!
Electrical shock hazard.
Turn OFF electric power at fuse box or service
panel before making any electrical connections and
ensure a proper ground connection is made before
connecting line voltage.
Failure to do so can result in property damage,
bodily injury or death.

Blocked vent shut-off (BVSO
For chimney venting
WARNING
!
IT IS IMPERATIVE THAT THIS DEVICE BE INSTALLED BY
A QUALIFIED AGENCY.
This device is designed to detect the insufficient evacuation of
combustion gases in the event of a vent blockage. In such a case
the thermal switch will shut down the oil burner. The device will then
need to be re-armed MANUALLY.
Refer to the wiring diagrams and the detailed instructions supplied
with the BVSO for the installation and wiring procedures. The length
of wires supplied with the unit is such that the safety device must be
installed between the flue outlet of the appliance and the draft
regulator, as indicated in the instructions.
Refer to the wiring diagrams and the detailed instructions supplied
with the BVSO for the installation and wiring procedures. The length
of wir es supplied with the unit is such that the safety device must be
installed between the flue outlet of the appliance and the draft
regulator, as indicated in the instructions.
It is further imperative that the BVSO be maintained annually. Refer to
the instructions supplied with the device for more details.
1.9)
1.9.1)
Power will be available to the EAC at all times, so it must incorporate a
flow proving switch if it is to be wired into the furnace control box. Most
modern EACs have the required integral airflow -proving switch.
1.9.2)
Terminals are provided to direct 115 volts @ 1.0 Amp maximum to the
transformer powering the humidifier. The humidifier will be energized
anytime the blower is operating on the "Heating Speed". Wire the 115-
volt power as indicated in Figure 6.
1.9.3)
An air conditioning coil may be installed on the supply air side only.
Also, notwithstanding the evaporator coil manufacturer's instructions,
a minimum of 6 inches of clearance must be allowed between the
bottom of the coil drain pan, and the top of the heat exchanger. Wire
the thermostat and condensing unit contactor as indicated in Figure 6.
1.9.4)
Installation
Design and install the air distribution system to comply with Air
Conditioning Contractors of America manuals or other approved
methods that conform to local codes and good trade practices.
When the furnace supply ducts carry air outside the furnace area, seal
the return air duct to the furnace casing and terminate the duct outside
the furnace space.
Install the air conditioning cooling coil (evaporator) on the downstream
side in the supply air plenum or furnace.
If a separate evaporator and blower unit are used, install good sealing
dampers for air flow control. Cold air from the evaporator coil going
through the furnace could cause condensation and shorten furnace
life.
)
Dampers (purchased locally) MUST be automatic.
