XI Service and Maintenance

The following routine maintenance should be performed on an annual basis:

1)Turn off electrical power and gas supply to the boiler

2)Inspect the flue passages for signs of blockage. If there is any carbon in the combustion chamber or the flue passages, clean the heat exchanger before proceeding further. See the cleaning procedure below.

3)Remove any debris found in the combustion chamber, being careful not to disturb combustion chamber insulation.

4)Remove all burners, noting the location of the pilot main burner. If burners show signs of deterioration, they should be replaced (some discoloration around the burner ports is normal). Clean the burners by first brushing the ports with a soft bristle brush and then vacuuming out any debris through the venturi opening.

5)Inspect the pilot assembly:

•Standing Pilots - Check the thermocouple for deterioration (some discoloration of the thermocouple is normal). If any deterioration is present, replace the thermocouple. Inspect the pilot assembly for deposits and deterioration. Clean or replace the pilot assembly as necessary.

•Intermittent Pilots - Clean any deposits found on the electrode and grounding strap. The ideal gap between the electrode and the ground strap is 1/8”. Inspect the porcelain for cracks or other deterioration. Replace pilot assembly if deterioration is found.

6)Inspect the combustion chamber insulation for deterioration.

7)(Intermittent Pilot Boilers) - Inspect the ignition cable insulation for cracks or other deterioration. If deterioration is found, replace cable.

8)Reinstall burners, being careful to put the pilot main burner in its original location.

9)Inspect all boiler wiring for loose connections or deterioration.

CAUTION

LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER SERVICING

10)Inspect the vent system:

•Make sure that both the vent system is free of obstructions.

•Make sure that all vent system supports are intact.

•Inspect joints for signs of condensate or flue gas leakage.

•Inspect venting components for corrosion or other deterioration. Replace any defective vent components.

11)Inspect the boiler and hydronic system for leaks.

CAUTION

WATER LEAKS CAN CAUSE SEVERE CORROSION DAMAGE TO THE BOILER OR OTHER SYSTEM COMPO- NENTS. REPAIR ANY LEAKS FOUND IMMEDIATELY

12)Place the boiler back in operation using the procedure outlined in “Start-up”. Check the pilot line and any other gas piping disturbed during the inspection process for leaks.
