Installation & Service Manual
I. CHECK THERMOSTAT OPERATION.
Raise and lower thermostat setting as required to
start and stop burner.
WARNING
Before installation of the boiler is considered
complete, the operation of all boiler controls
must be checked, particularly the primary
control and high limit control.
J. Verify Oil Primary Control Features using procedures
outlined in Instructions furnished with control or
instructions as follows:
1. Priming the Pump
a. Prepare the burner for priming by attaching
a clear plastic hose over the bleed port
fitting and fully opening the pump bleed
port. Use a suitable container to collect
purged oil.
b. Initiate a call for heat.
c. After the burner starts, press and hold the
ACTION button for 15 seconds until the
yellow light turns on. This indicates that the
button has been held long enough.
d. Release the ACTION button. The yellow
light will turn off and the burner will start up
again.
e. At burner starts up, click the ACTION button
while the igniter is still on. This will transition
the control to a dedicated Pump Prime mode,
during which the motor, igniter, and valve are
powered for four minutes. The SYS light will
be solid yellow for the duration of Pump Prime
mode.
f. Bleed the pump until all froth and bubbles
are purged. If desired, terminate the call for
heat or hold the ACTION button for at least
one second to exit Pump Prime mode and
return to Standby.
g. At the end of 4 minutes, SYS light will turn
from yellow to green and the control will
automatically return to standby mode.
h. If prime is not established during the four-
minute pump prime mode, return to step 5
to re-enter Pump Prime mode. Repeat steps
5 through 7 until the pump is fully primed
and the oil is free of bubbles.
i. Terminate the call for heat, and the control
will resume normal operation.
2. Safe Start Check
a. Place a jumper across the cad cell
terminals.
b. Initiate a call for heat.
c. Burner must not start. Verify that the SYS
light is green, FLM light is yellow, and that
the control remains in Standby mode.
d. End the call for heat and remove the cad
cell jumper.
3. Simulate Flame Failure and Ignition Failure
a. Initiate a call for heat.
b. After the flame is established and the
burner igniter turns off, close the hand valve
in the oil supply line.
c. At flame loss, the control will enter Recycle
mode. Verify that the SYS light is flashing
yellow. The control will remain in Recycle for
60 seconds
d. After the 60 second recycle period, the
control will try to restart the system.
e. After the 15 second lockout time, the control
will lock out the burner and the SYS light
will flash red. Verify that the burner motor
and igniter are off and that the burner oil
solenoid valve (if used) is not energized.
f. Open the hand valve in the oil line.
g. Click the ACTION button and verify that
the SYS light shows green and the burner
lights.
h. End the call for heat.
K. IF CONTROLS DO NOT MEET REQUIREMENTS
outlined in Paragraph I., Replace control and
repeat checkout procedures.
L. BECKETT GENISYS 7565 PRIMARY CONTROL
1. Sequence of Operation (See Figure 8-4)
a. Standby: The burner is idle, waiting for a
call for heat.
b. Validate Air: once the motor turns on and if
configured, the control will prove air before
pre-purge. This feature requires either a
pressure switch or a spill switch.
c. Valve-On Delay: Pre-Purge, the igniter
and motor are on while the control delays
turning on the oil solenoid valve for the
programmed time. This feature requires
either a Beckett Clean-Cut pump or an
external valve.
d. Trial For Ignition (TFI): If used, the oil
solenoid valve is energized. A flame should
be established within the factory set trial for
ignition time (“lockout time”).
e. Ignition Carryover: Once flame is
established, the igniter remains on for the
configured carryover time delay to ensure
flame stability.
