Service & Maintenance - Crown Boiler BSI069 Installation Instruction

On a continuous basis:
1) Keep the area around the boiler free and clear from combustible materials, gasoline, and other flammable vapors and
liquids.
2) Keep the area around the boiler and boiler room ventilation openings clear of objects which might obstruct the flow of
combustion and ventilation air.
On at least a weekly basis:
For boilers equipped with a #67 low water cut-off, blow down the low water cut-off following the instructions on the yel-
low sticker adjacent to the low water cut-off. During this blow down, the low water cutoff should shut down the burners. If it
does not the low water cut-off should be replaced immediately.
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. 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 dete-
rioration is found.
6) Inspect the combustion chamber insulation for deterioration.
7) Inspect the ignition cable insulation for cracks or other deterioration. If deterioration is found, replace cable.
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS
CAN CAUSE IMPROPER AND DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER
SERVICING.
8) Reinstall burners, being careful to put the pilot burner back in its original location.
9) Inspect all boiler wiring for loose connections or deterioration.
10) Inspect the vent system:
•
Make sure that 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 system for leaks.
12) Inspect the low water cut-off:
•
For Hydrolevel CG400A low water cut-offs - Remove and inspect the probe for scale and sediment buildup. Clean
any sediment or scale from the probe with a scouring pad or steel wool. Consult the Hydrolevel CG400 manual for
any additional maintenance information. Test the low water cut-off before placing the boiler back into service.
