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.

CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

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 chamber 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.
