The correct operation of ANY programmer and all other
system controls should be proved. Operate each control
separately and check that the main burner or circulating
pump, as the case may be, responds.
5.
With the system HOT, examine all water connections for
soundness. Then turn OFF the gas, electricity and water
supplies to the appliance and drain down whilst the system
is still hot, in order to complete the flushing process. Refill
and vent the system and again check for water soundness.
6.
Finally, set the controls to the user's requirements.
The temperatures quoted below are approximate and vary
between installations.
Make the following checks for correct operation:
1.
Turn the boiler thermostat OFF and ON and check that the
main burner is extinguished and relit in response.
2. 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 (H) and note the time taken for the flame failure
device to shut down - identified by a click within the gas
control valve.
b.
Open the gas service cock and relight the pilot.
3.
With the burner alight again, 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 provides a safety delay period
before the pilot can be relit.
