25 GENERAL CHECKS
Make the following checks for correct operation:
1.
Turn the boiler thermostat OFF and ON to check that the
main burner is extinguished and relit in response.
2.
Check that the programmer, if fitted, and all other system
controls function correctly.
Operate each control separately and check that the main
burner or circulating pump (as the case may be) responds.
3. Flame failure device
Check the operation of the flame failure device in the gas
control valve as follows:
a.
Extinguish the pilot flame by closing the gas service
cock and note the time taken for the flame failure
device to shut down - identified by a click within the gas
control valve.
This must not be longer than 60 seconds.
b.
Open the gas service cock and relight the pilot.
c.
Turner the boiler thermostat ON. The burner should
light.
d.
Turn the gas control knob to the OFF position - refer to
Frame 23. The main burner and pilot flame should shut
down immediately.
Note.
A latch in the gas control
valve provides a safety delay period of approximately
30 seconds before the pilot can be relit.
