CAUTION
Before a gas boiler may be put into operation and tested, it’s gas connection must be
leak tested. After installation of oil/gas-fired boiler, operation and performance tests
shall be conducted to make certain that the burner is operating in an acceptable
manner and that all safety controls and devices function properly.
It is critical that
the high limit, low water cutoff and burner "cad cell" relay be checked for normal
operation before leaving the job.
12. Maintenance
NOTICE
Label all wires prior to disconnection when servicing controls. Wiring errors can cause
improper and dangerous operation.
The boiler system should be serviced once a year.
1. Turn boiler safety switch off.
2. Open lower swing door and remove upper clean out plate.
3. Brush upper passages first and then clean combustion chamber of any debris with
brush and vacuum.
4. Remove smoke pipe and clean out debris from cleaning or soot build up.
5. Inspect smoke pipe for any corrosion before reinstalling. Replace if necessary.
6. Consult the burner manufacturers manual for annual maintenance of the burner.
7. Once the burner has been serviced, check the combustion and verify it against
Section 8 on page 17 of this manual.
8. Inspect the boiler and make sure it is operating normally, i.e. temperature and
pressure.
9. Inspect the Pressure Relief Valve and manually set it off to ensure it is operating
normally and not leaking.
10. If a Low Water Cut-Off is installed follow the manufactures suggested maintenance
and test procedures.
11. Adjust room thermostat so there is a call for heat and test boiler high limit for proper
operation.
12. Remove all combustible materials from around boiler and ensure the area is free of
debris so the burner has adequate intake air supply.
Verify proper operation of high limit, low water cutoff and burner “cad cell” after
servicing.
