as long as the button is held and will return to standby
when released.
Cad Cell Resistance Measurement:
If the Beckett 7505 control is equipped with the GeniSys
Display Module, part 52067U, the cad cell resistance can
be selected and read on the LCD screen. Also, the GeniSys
Contractor Tool, part 52082U, can be used for this purpose.
If these are not available, the cad cell leads can be
unplugged from the control and the resistance measured
with a meter in the conventional way. Conduct these
tests with fl ame present.

Hot Gas Puff-back and
Heavy Smoke Hazard
Failure to bleed the pump properly
could result in unstable combustion,
hot gas puff-back and heavy smoke.
Do not allow oil to intermittently spray into a hot
combustion chamber while bleeding.
Install a gauge in the nozzle discharge port tubing or
fully open the pump bleed valve to prevent oil spray from
accumulating in the combustion chamber when venting
air from the fuel pump.
Ensure that all bubbles and froth are purged from the oil
supply system before tightening the pump air bleed valve.
