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
The flame failure device must cut off the gas to the burner
within 60 seconds.
Check the operation of the flame failure
device in the gas control valve as follows:
a.
With the burner alight, turn the gas control knob
clockwise until resistance is felt and then release it. The
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.
b.
The correct operation of external system controls
should be proved. Turn each, in turn, to OFF and ON
and check that the main burner or circulating pump
responds.
