After the flame detection device is satisfied that a stable flame
has been established, the burner programmer releases the burner
for control by the temperature controller (supplied by others).
The air control motor will be positioned to satisfy the set point
of the temperature controlling instrument. The air valve opens
which results in an increased air pressure at the burner. The gas
ratio-controller supplies a gas flow corresponding to the amount
of combustion air.
The high fire gas flow is limited by an adjusting valve, that has to
be adjusted for the specified gas type at the location of
operation.
