School Boiler Maintenance Program

With the fall heating season upon us, it is a good time to reconsider steps that need to be taken prior to starting steam boilers after a lay-up period. While this list is not all-inclusive, it can serve as a guide for those responsible for boiler operation.

Before a steam boiler is placed in operation, boiler operators and other responsible personnel and/or supervisors must check over the entire system and carefully review operating procedures.

Operating Manuals

All manufacturers of boilers and fuel burning systems supply operating manuals with their equipment. Unfortunately, many boiler rooms do not have manuals and operating instructions available. These manuals have either been lost or misplaced. It is the responsibility of the responsible supervisor to obtain these publications and see that they are read, understood, followed and available in the boiler room.

Maintenance During Summer Lay-up

The summer shutdown period is a good time to accomplish necessary boiler and fuel burning system preventative maintenance. A suggested check list of such maintenance follows:

	Drain and flush the boiler, open all handholes and manholes, clean and remove soot and scale from the firesides. Examine the boiler for damage and corrosion.
	Have the boiler inspected by an authorized inspector, as required.
	Install new gaskets, replace all handhole and manhole covers, refill boiler and perform a hydrostatic test, if required.
	Institute a suitable boiler water treatment program to reduce scale buildup and corrosion.
	Have the fuel burning equipment cleaned and adjusted by a competent service technician. Have the technician disassemble the low water cutoff and water feeding devices, clean, recondition and reassemble them. Have the technician leak test all fuel safety shutoff valves.
	Lubricate all mechanical equipment such as fans and pumps; verify motor rotation.
	Check all boiler piping for leaks and missing insulation.
	Make sure provision is made for establishing and keeping a boiler log.

Start-up Check-List

Immediately prior to boiler start-up perform the following:

	Check that all ventilation and combustion air openings and louvres are clean and free of debris.
	Verify boiler water level.
	Check that all stack dampers are open.
	Examine the boiler furnace for foreign material.
	Check the furnace and flue passages for fuel accumulation.
	Make sure the manual fuel valves are open.
	Verify operation of all operating and limit controls, interlocks and gauges.
