OPERATIONAL CHECKLIST
1=> Is the electrical wiring completed according to
Figures 4.1 to 4.3, p. 16 to 18?
2=> Is the blower access door secured in place?
3=> Is the valve on the oil line open?
4=> Is the "RESET BUTTON'' on the primary control
pushed down?
5=> Are the flame observation door and the two cleanout
access doors located at the front of the unit closed?
6=> Is the room thermostat in the heating mode and set
above room temperature?
7=> If yes, put the main electrical switch to the "ON''
position and the burner should start.
CAUTION
Do not tamper with the unit or its controls. Call a
qualified service technician.

COMBUSTION CHECK
In order to obtain optimum performance from the oil burner, the
following set-up procedures must be followed (refer to the technical
specifications table, p. 12 in this manual):
1.
Using a test kit, measure the smoke level and adjust it to a
"trace" level (between 0 and 1). It is recommended to use a
Bacharach true spot smoke test set or equivalent;
2.
For chimney installation only: in order to ensure the proper
draft through the furnace, a barometric draft regulator must be
installed as closely to the breach of the furnace as possible. In
order for this device to function properly, the barometric
damper must be mounted with the hinge pin horizontal and the
face of the damper vertical (see instructions included with
damper). The draft regulator should be adjusted after the
furnace has been firing for at least five minutes and set
between -.025" W.C. and -.035" W.C.;
3.
For flue pipe pressure on sidewall installations (VTK), refer to
the technical specifications in this manual;
4.
The overfire draft, which is taken through the observation door
(located in the center line above the burner in the front panel of
the furnace), is a measurement that is necessary to determine
if there is a blockage in the heat exchanger or the flue pipe.
Refer to the Technical Specifications in this manual for overfire
pressure values. A high pressure condition may be caused by
excessive combustion air due to the air band being too wide
open or a lack of flue draft (chimney effect) or some other
blockage, such as soot, in the secondary section of the heat
exchanger or the use of an oversize nozzle input or high
pressure pump;

OPERATION
5.
The CO
obtain the data that are required to determine the terminal
efficiency of the furnace. Although this information is good to
have, it is not essential in the basic set up of the furnace. The
proper procedure for performing this operation is as follows:
a.
Start the appliance and from the test port near the
BREACH PLATE (VTK) location or on the flue pipe just
before the draft regulator (chimney), proceed with smoke
test and adjust the burner to get between a trace to a #1
smoke rating after a minimum of 5 minutes of operation;
b.
Take a CO
c.
Open the burner air shutter to get 1.5% CO
previous reading and take a smoke test in this condition;
d.
The new reading should now be ZERO smoke;
6.
A 10 micron (or finer) oil filter should be installed as closely to
the burner as possible, on all oil burners, but it is particularly
essential on lower firing rate burners. We recommend the use
of a low pressure drop oil filter with a greater capacity than the
fuel pump;
7.
On a new installation, the air entrapped in the oil line leading
from the tank to the nozzle must be thoroughly purged in order
to prevent excessive after drip. The oil pump is provided with a
special fitting that will enable you to purge any air between the
tank and oil pump;
The proper procedure for performing this operation is as
follows:
a.
Place a piece of 6 mm (1/4") diameter clear plastic tubing
over the purge fitting on the oil pump;
b.
Start the oil burner, then open the purge fitting and allow
the burner to run until the purge tube is completely free of
air bubbles;
c.
At this point tighten the purge fitting, which will allow the
oil to run to the nozzle and fire the burner. If the purging
takes longer than 15 seconds and no flame has been
established the burner will stop. Push the reset button on
top of the Primary Control to restart burner.
For detailed information on the operation of the Primary Control
refer to the instructions included with the furnace or burner.
8.
After all the set-up procedures mentioned above are
completed, the burner should be fired and an inspection mirror
should be used to observe the flame pattern at the tip of the
nozzle. Any irregularities such as burning to one side or
pulsating flame patterns should be corrected by changing the
nozzle.

FAN ADJUSTMENT CHECK
This furnace is equipped with a 4 speed direct drive motor to deliver
a temperature rise within the range specified on the rating plate.
Adjust the fan speed ACCORDING TO THE OIL INPUT
SELECTED, so that the temperature rise is within the range
specified on the rating plate (see Table 3, p. 12.) Consult the wiring
diagram for speed changes on the direct drive motor.
The blower start / stop is controlled by a helical bi-metal Fan-Limit
Control, which is adjusted to start at 43°C (110°F) and stop at 32°C
(90°F). These are factory set limits which must not be changed or
tampered with.
