CHECKS
After starting up the burner, check the safety devices (photoresistance,
block, thermostats).
1) The photocell is the flame control device and so it should trip
if the flame extinguishes during operation (this check should
be made after at least 1 minute from lighting up).
2 The burner should be capable of blocking itself and
remain so when a normal flame does not come on during
start-up cycle and within the preset on control box.
The "lock-out" causes the motor and the burner to stop
immediately and corresponding "lock-out" warning lamp lights
up.To check the function photoresistant-cell and lock-out
system proceed as follows:
a) Start up the burner.
b) After at least one minute, remove the photo-cell from its seat
and pull it out and simulate flame failure by covering the photo-
cell (use a rag to close the window in the photocell support).
The burner flame should go to lock-out.
c) Keep the photo-cell in the dark and the burner will start again,
but the photo-cell does see the light and the burner goes to
lock-out within the time preset by control box. The control
box can be reset only manually by pressing the appropriate
push-button.
3) To check the thermostat efficiency, run the burner until the
water in the boiler reaches a temperature of at least 50 °c
and then turn the thermostat control knob to reduce the
temperature until an opening click is heard and simultaneous
stopping of the burner. The thermostat should trip within a
maximum tolerance of 5 to 10 °C in respect to the control
thermometer (boiler thermometer); if not, change the setting
on the thermostat scale to match that of the thermometer.
