After the burner is mounted
1. Remove drawer assembly;
2. Install nozzle (see specifications);
3. Confirm electrode settings;
4. Make the electrical connections;
5. Complete oil line connections.
CAUTION
7
NEVER use the “interrupted ignition” function if a
Honeywell R7184 series combustion relay is installed
on the burner.
CAUTION
Do not fire the burner until you have checked the
following:
Checking the polarity
Oil burners used on furnaces have solid state control systems which
make them sensitive to the proper connection of the hot and neutral
power lines. The controls will be damaged if the 2 wires 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 (see
Figure 1);
5. If you do not have a voltmeter, use a pilot light.
FIGURE 1
Checking the nozzle
The burner is equipped with the appropriate nozzle. However, If
another size nozzle is required, use the manufacturer’s nozzle data
concerning spray angle, as shown in Table 2. Note that all nozzle
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.
Checking air and turbulator settings
Before starting the burner for the first time, adjust the air and turbulator
settings to those listed in Table 2. 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 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. These instructions must be followed in order for the
lifetime heat exchanger warranty to remain 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 (BVSO
)
For chimney venting
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.
DNS-0864 Rev. A
It is further imperative that the BVSO be maintained annually. Refer to
the instructions supplied with the device for more details.
CAUTION
A positive pressure venting system (Sealed Combustion
System or Direct Vent) MUST NOT use the BVSO. Follow
the instructions supplied with the venting system.
