Hearing the solenoids snap on after the
10 second purge delay means that power
is coming to and through the Fenwal
board. The Fenwal board is probably okay.

•

If flame is sensed, the power to the sole-
noids stays on but the power to the ignitor
always goes off after about four(4) seconds.

•

Power to the low pressure solenoid is al-
ways on anytime flame is sensed. This is
because the power to the low solenoid is
hooked directly across terminals V1 and
V2 of the Fenwal board.

•

Power to the high pressure solenoids is
controlled by the Plenum thermostat. One
side of the solenoid is hooked to V2(neutral)
and the other side is run through the nor-
mally closed switch of the thermostat and
then back to V1. This is how the burner is
made to cycle. When the plenum is below
tem perature, power is run through the ther
mostat to the high pressure solenoid.  When
temperature is reached, the thermostat opens
and the high solenoid loses power.

•

L2 and V2 are connected internally in the
Fenwal, and they must be nuetral.

•

Make sure that the ignitors are mounted
correctly through an opening in the burner
skirting.   Also, make sure that they are not close
enough to the edges of  the opening to cause a
spark  to jump the skirting, instead of between
the  ignitors.

•

Be sure that the ignitor tips are no more than
1/8" apart from each other.

•

Make sure that the wire connections on  the
ignitors are good and tight.

•

On stubborn lighting  burners  reverse the
direction the ignitor  tips are facing.  Instead of
having  the tips  pointing  toward  the  fan or  burner,
change the direction so the tips are  facing  the ex-
haust end of the dryer. (This is especially true on
burners with no burner cone installed (i.e. Nat-
ural Gas).
