BC: No Pre-Purge
For setting 1, there will only be no pre-purge if the burner has recycled due
to meeting operational temperature/ pressure, and the system has gone
through VPS checks successfully. If the burner has a lockout, or is restarting
after a lockout has been cleared, then the MM will force a pre-purge. No
pre-purge is only available when the fuel is set to gas.

For setting 0, and external air pressure switch must be wired to terminal 54.
If a reset of voltage is not detected within 2 minutes on terminal 54 during
the ‘Wait for Air Switch’ phase before running to purge, a lockout
will occur. For setting 1, the air pressure sensor will look for zero air
pressure in the ‘Zero Air Sensor’ phase before running to purge. Setting 2
includes the checks made for settings 0 and 1.

using an Autoflame air pressure sensor. See parameter 43 for air pressure
display units.
