START-UP PROCEDURES

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.
