Check Condensate Drain

1. Remove burner cover panel (if still installed) as per
the removal and reinstallation instructions on page
6 in this manual, and reinstall panel upon completion
of service work.
2. Check electrodes for wear and contamination.
3. Clean electrodes with small brush or emery paper.
CAUTION
Do not damage wire mesh when cleaning.
4. Check clearances. If clearances are not satisfactory
or the electrodes are damaged, replace electrodes and
gasket A and align.
Tighten fastening screws for the electrodes to a
torque of 1.5 lb.ft. / 2 Nm.
Ensure condensate drains freely (e.g. at siphon trap A).
If necessary, clean siphon trap.
If the condensate does not drain freely, condensate will
accumulate in bottom part of boiler resulting in a burner
shut-down (fault message).
