H. CHECK FOR CLEAN CUT OFF OF
BURNER.
1. AIR IN THE OIL LINE between fuel unit and
nozzle will compress when burner is on and will
expand when burner stops, causing oil to squirt from
nozzle at low pressure as burner slows down and
causing nozzle to drip after burner stops. Usually
cycling the burner operation about 5 to 10 times will
rid oil line of this air.
2. IF NOZZLE CONTINUES TO DRIP, repeat
Paragraph I, No. 1. If this does not stop the
dripping, remove cut-off valve and seat, and wipe
both with a clean cloth until clean, then replace
and readjust oil pressure. If dripping or after burn
persist replace fuel pump.

The R7184 is a microprocessor-based
control. The indicator light provides
diagnostic information for lockout, recycling
and patented cad cell status. There is a
manual reset button to exit the Lockout
Mode and enter the Idle Mode (see Figure
28).
ii. Pump Priming Cycle: To facilitate purging
air from the oil lines and fi lters, the R7184
can be placed in a purge routine by pressing
and releasing the reset button during the
safety check, delayed valve-on, ignition or
carry-over periods.
iii. Limited Recycle: This feature limits the
number of recycle trials (for each call
for heat) to a maximum of three trials. If
the fl ame is lost three times and does not
successfully satisfy a call for heat, the
R7184 locks out.
iv. Limited Reset (Restricted Mode): In order
to limit the accumulation of unburned oil in
the combustion area, the control can only be
reset three times. The reset count returns to
zero each time a call for heat is successfully
completed.
•
To reset from Restricted Mode: Press and
hold the reset button for 30 seconds.
When the LED fl ashes twice, the device
has reset.
