Checking The Polarity; Checking The Nozzle; Checking Air And Turbulator Settings; Checking The Fuel Supply System - Dettson OLR105A12D Mode D'emploi

CAUTION
Do not turn on the burner until you have checked the
following:
2.7.3

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.
Set your voltmeter to line voltage;
1.
Place one prong on your grounded electric entry box
2.
and one prong on the black wire;
Read the voltage;
3.
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.

2.7.4

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 3 to 5. 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.
2.7.5

Checking air and turbulator settings

Before starting the burner for the first time, adjust the air and
turbulator settings to those listed in Tables 3 to 5. Once the
burner becomes operational, final adjustments will be
necessary.
2.7.6

Checking the fuel supply system

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.

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.
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. It
is required that this practice be followed in order for the
lifetime heat exchanger warranty to be kept intact.
2.7.7

Blocked vent shut-off (BVSO)

For chimney venting
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.
Please 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.
A positive pressure venting system (Sealed Combustion
System or Direct Vent) MUST NOT use the BVSO. Follow
the instructions supplied with the venting system.
It is also essential that the BVSO be maintained annually.
For more details please refer to the instructions supplied
with the device itself, as well as Section 4 of this Manual.
