C. CHECK-OUT PROCEDURE
1. After starting the boiler, be certain that all controls
are working properly. Check to be sure that the
boiler will shut down when the water temperature
reaches the control board set point.
2. To check operation of the ignition system safety shut-
off features:
a) Turn off gas supply.
b) Set thermostat or controller above room
temperature to call for heat.
c) The boiler should perform 3 attempts at ignition
before going into lock-out.
d) Turn gas supply on.
e) Reset by pushing S4 "Reset" key.
f) Observe boiler operation through one complete
cycle.
3. Turn off the automatic fill to the boiler and drain
some water to drop the system pressure below 10
psig. Verify that the display module reads "PRO"
after 5 seconds and does not allow the boiler to
operate. Close the boiler drain and turn on the
automatic fill valve.
4. Low Water Cut-Off (if used) - Consult the
manufacturer's instructions for the low water cut-off
operational check procedure.
5. Check the system to assure that there are no leaks or
overfilling problems which may cause excessive
make up water to be added. Make up water may
cause liming in the boiler and corrosion in ferrous
system parts.
6. 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.
7. Check the condensate drain hose (and pump if
installed) and make sure all condensate is being
removed from heat exchanger.
8. Review operation with end-user.
9. Complete the Warranty Card and submit it to PB
Heat.
10. Hang the Installation, Operation, and Maintenance
Manual in an accessible position near the boiler.
