b. Intermittent Ignition System:
i) Turn gas supply off.
ii) Set thermostat or controller above room
temperature to call for heat. Watch for igniter
glow at pilot burner.
iii) Igniter will continue to glow for 30 seconds,
de-energize for 30 seconds, then re-energize
and glow for another 30 seconds. It will then
de-energize for 5 minutes before restarting
the sequence.
iv) Turn gas supply on.
v) Reset the boiler and control by following
Operating Instructions.
vi) Observe boiler operation through one
complete cycle.
3. Low Water Cut-Off (if used) – Consult the
manufacturer’s instructions for the low water cut-off
operational check procedure.
4. Check the system to make sure there are no leaks or
overfilling problems which might cause excessive
make-up water to be added. Make-up water causes
liming in the boiler and brings in oxygen. Oxygen
can cause severe damage to the boiler though
oxygen corrosion pitting.
5. Check the expansion tank and automatic fill valve (if
used) to confirm that they are operating correctly. If
either of these components causes high pressure in
the system, the boiler relief valve will weep or open,
allowing fresh water to enter the system.
6. Do not allow the system controls to subject the boiler
to excessively low water temperatures, which would
cause condensation of flue gases and corrosion of
the boiler. Operate the boiler at a temperature above
130°F (54°C). Adjust the boiler limit as required to
maintain boiler temperature above this level.
7. Check the general condition of the system including
piping support, joints, etc. Check cleanliness of the
radiators, baseboard units and/or convectors. Clean
them to the extent possible. If radiators do not heat
evenly, vent any remaining air from them.
8. Review operation and User’s Information Manual
with end-user.
9. Complete the Warranty Card and submit it to
PB Heat, LLC.
10. Hang the Installation, Operation and Maintenance
Manual and User’s Information Manual in an
accessible position near the boiler.
