The control has finished purge and the firing rate motor is driving to the low fire
position (term. 10-12 made) waiting for the low fire start switch (term. M-D) to
close. It will hold this position for ten (10) minutes and then lockout if the M-D
circuit does not close, excluding the EPD167.
The running interlock circuit (3/P) has not closed within the first ten (10) seconds
of purge. The control will hold for ten (10) minutes and then lockout.
