g) Burner Programmer
i. Is located in the center of the control panel. Acts in conjunction with a
sensing device to ‘supervise’ the ignition sequence, prove the flame is
satisfactory and finally ‘monitor’ the established flame.
Should any fault occur, either during the ignition sequence or during
normal running, the programmer will immediately go to ‘lock-out’ and both
main and pilot gas/oil valves will shut to isolate the fuel line
to the burner. Lockouts include high steam pressure, low water, high/low
gas pressure and flame failure.
h) Flame Failure Indicator

condition.
