Installation & Service Manual
3. CHECKOUT
Put the system into operation and observe
at least one complete cycle to make sure
that the controller operates properly. See
Troubleshooting Section to use LED to assist in
determining system operation.
E. CHECK OIL BURNER BEFORE STARTING.
If a lower input is desired, remove the nozzle
which was factory installed. Locate the lower
firing rate nozzle that is supplied loose. Confirm
the nozzle is the proper size and type for the
lower firing rate as specified in Table 14-1 (at the
rear of this manual). Install the proper nozzle in
the burner nozzle adapter.
Adhere the Conversion Rating Label for the
selected model on the boiler jacket adjacent to
the existing Rating Label on the boiler.
1. CHECK BURNER SETTINGS and readjust if
necessary, see Burner Specifications, Table
14-1 at rear of manual.
2. Beckett Burners
a. Inspect Beckett head setting on left side
of burner housing by insuring the blue line
MD(V1) or the line on the label MB(L1) are
aligned, readjust if necessary. Refer to
Figure 2-1 and Table 14-1 at the rear of this
manual.
b. Check burner air band and air shutter
settings. Readjust if necessary, see Burner
Specifications Table 13 at the rear of this
manual.
c. OPEN ALL OIL LINE VALVES.
d. Attach a plastic hose to fuel pump vent
fitting and provide a pan to catch the oil.
e. OPEN FLAME OBSERVATION PORT
COVER on burner swing door.
F. START OIL BURNER.
1. Open vent fitting on fuel pump.
2. TURN ‘ON’ BURNER service switch and
allow burner to run until oil flows from vent
fitting in a SOLID stream without air bubbles
for approximately 10 seconds.
3. Close vent fitting and burner flame should
start immediately after prepurge is completed.
Prepurge prevents burner flame until 10
seconds has elapsed after initial power is
applied to burner. During prepurge the motor
and igniter will operate but the oil valve will
remain closed. Refer to Oil Primary Control
Instructions for more details.
4. Adjust oil pressure.
a. When checking a fuel unit’s operating
pressure, a reliable pressure gauge may
be installed in either the bleeder port or
the nozzle port. For Beckett burner refer to
Figure 8-1.
b. Locate oil pressure adjusting screw and
turn screw to obtain proper pump pressure,
refer to Table 14-1 at the rear of this manual.
c. To check the cutoff pressure, deadhead a
reliable pressure gauge onto the copper
connector tube attached to the nozzle port.
Run the burner for a short period of time.
Shut the burner off. The pressure should
drop and hold.
d. Remove the gauge and install bleeder port
and/or reconnect the nozzle port line.
G. ADJUST OIL BURNER WHILE OPERATING.
