CAUTION
Do not turn on the burner until you have checked
the following:
Checking the polarity
The oil burner used on the furnace has a solid state control
system which is sensitive to the proper connection of the hot and
neutral power lines. The controls will be damaged if the two lines
are reversed.
1.
Set your voltmeter to line voltage;
2.
Place one prong on your grounded electric entry box and
one prong on the black wire;
3.
Read the voltage;
4.
If the voltage is zero, check the white wire. If line voltage
shows, reverse the 115-volt leads entering the furnace
junction box;
5.
If you do not have a voltmeter, use a pilot light.

Checking the nozzle
The burner is equipped with the appropriate nozzle. However, if
another size nozzle or replacement nozzle is required, use the
manufacturer's nozzle data concerning spray angle, type as
shown in Tables 4.1 to 4.3. Note that all nozzle sizes are based
on a pump pressure of 100 psig.
Always select nozzle sizes by working back from the actual
desired flow rate at operating pressure, and not by the nozzle
marking.
Checking air and turbulator settings
Before starting the burner for the first time, adjust the air and
turbulator settings to those listed in Tables 4.1 to 4.3. Once the
burner becomes operational, final adjustments will be
necessary.
Checking the fuel supply system
Fuel Specifications
NOTE: 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 .75 USGPH,
the Installation Code for oil burning equipment
requires the installation of a 10 (or less) micron filter
in the fuel oil line. ICP requires that this practice be
followed in order for the lifetime heat exchanger
warranty to be kept 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 the
oil used on certain parts during manufacturing.
1.8
BLOCKED VENT SHUT-OFF DEVICE (BVSO)
For chimney venting
WARNING
It is imperative that this device be installed by a
qualified technician.
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 restarted 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.
It is further imperative that the BVSO be maintained annually. Refer to
the instructions supplied with the device itself, as well as Section 3. of this
Manual.
Do NOT use the BVSO on a positive pressure venting
system (Sealed Combustion System or Direct Vent).
Follow the instructions supplied with the venting system.
1.9
INSTALLING ACCESSORIES
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 could result in death, bodily injury
and/or property damage.
1.9.1
Electronic air cleaner
Wire leads are provided to direct 115 volts @ 0.5 Amp maximum to an
Electronic Air Cleaner (EAC). 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. Wire the electronic air cleaner as indicated in Figure 6.
