Maintenance - Biasi SG 2 Manual And Installation Instructions

Page 34
Before a gas boiler may be commissioned, it's gas connection must be leak tested before the
boiler may be put into operation and 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.
Label all wires prior to disconnection when servicing controls. Wiring errors can cause
improper and dangerous operation.
The Biasi boiler system should be serviced once a year.
1. Inspect the boiler and make sure it is operating normally, I.e. temperature and pressure.
2. Inspect the Pressure Relief Valve and manually set it off three times to ensure it is
operating normally and not leaking.
3. If a Low Water Cut-Off is installed follow the manufactures suggested maintenance and
test procedures.
4. Adjust room thermostat so there is a call for heat and test boiler high limit for proper
operation.
5. Turn boiler safety switch off.
6. Open lower swing door and remove upper clean out plate.
7. Brush upper passages first and then clean combustion camber of any debris with brush
and vacuum.
8. Remove smoke pipe and clean out debris from cleaning or soot build up.
9. Inspect smoke pipe for any corrosion before reinstalling. Replace if necessary.
10. Consult the burner manufacturers manual for annual maintenance of the burner.
11. Remove all combustible materials from around boiler and ensure the area is free of debris
so the burner has adequate intake air supply.
