Operating principle
Combustion air is drawn into the closed air box, by a variable speed
fan, through the air inlet connection from the plant room (open flued)
or from outside via the concentric flue system (room-sealed). On the
inlet side of the fan is a specially designed venturi which is connected
to the outlet side of the gas combi block.
Depending on the demand (under the dictates of flow/return sensor
and other external/internal control inputs) the electronic control unit
directly monitors the volume of gas and air being delivered to the
premix burner. This mixture is initially ignited by the combined
ignition/ionisation probe which then monitors the state of the flame.
Should the flame not ignite or be unstable, within the pre-set safety
time cycle, the controls will shut the boiler down (after 5 attempts)
requiring manual intervention to reset the boiler. The digital display will
also indicate a flashing fault code confirming the reason for the failure.
