42 - Minimum gas pressure switch fails to close. . . . . . . . . . Adjust or replace
The burner continues to
repeat the start-up cycle,
without lockout 43 - The gas pressure in the gas mains lies very close to the
value to which the minimum gas pressure switch has
been set. The sudden drop in pressure after valve open-
ing causes temporary opening of the pressure switch
itself, the valve immediately closes and the burner
comes to a halt. Pressure increases again, the pressure
switch closes again and the ignition cycle is repeated.
And so on
Reduce the minimum gas pressure switch
intervention pressure. Replace the gas filter
cartridge.
