CL Installation & Service Manual
If safety switch shuts down burner and
resistance is above 1600 OHMS, open
line switch to boiler. Access cad cell
under ignitor, clean face of cad cell
and see that cell is securely in socket.
Check gasket around perimeter of ignitor
lid for proper seal. If gasket is missing
or damaged, replace gasket. Room light
can effect cad cell resistance. Reset
safety switch.
Close line switch to boiler. If burner starts
and runs beyond safety switch cut-off
time, cell is good. If not, install new cell.
Close hand valve in oil supply line.
Failure occurs, device enters Recycle
Mode.
Device tries to restart system after
approximately 60 seconds.
After third Recycle Mode trial, safety
switch locks out within safety switch
timing indicated on label and control
enters Restricted Mode. Ignition and
motor stop and oil valves closes.

established, turn the power off to the
control/burner. The burner should shut
down safely. When power is restored a
normal ignition sequence should be started.
WARNING
Cad Cell Jumper must be
removed after this check.
4. Check High Limit
a. Adjust system thermostat(s) to highest
setting.
b. Allow burner to run until boiler water
temperature exceeds high limit setting. The
burner should shut down and circulators
continue running.
c. Allow the temperature to drop below control
setting. The burner must restart.
d. Boiler installation is not considered
complete until this check has been made.
5. Check Low Water Cut-Off Control
a. Steam Boiler
Check Low Water Cut-off Control with water
level at normal water line (see Figure 1C).
Raise thermostat setting to allow burner to
operate. Open boiler drain to allow water
level to drop to bottom of sight glass until
burner operation is shut-down by low water
cut-off.
Close boiler drain and refill to normal water
line. Burner should automatically restart
during fill. Lower thermostat setting.
b. Water Boiler
Refer to Appendix "A" at the rear of this
