3.6 SUGGESTED MAINTENANCE SCHEDULE
DAILY
Make visual inspection of gauges, monitors, and indicators and record readings in boiler
system log.
Make visual check of instrument and equipment settings against factory recommended
specifications.
Check operation of float controls to ensure proper functioning. The lower piping
connections of float type level controls (if external float supplied) should have a suitable
blowdown valve piped into a proper discharge station. This valve should be opened
periodically to allow any sludge accumulated in the control to be flushed out. Consult
manufacturer’s instructions.
Check pump operation. See manufacturer’s data for detailed instructions.
WEEKLY
Confirm boiler room area is free of combustible materials and has no obstructions.
Check all limit controls as specified in manufacturer’s manual.
Check float low water cutoff as described above.
Make sure all fuses are in operating order.
MONTHLY
Make visual inspection of all wiring and components.
Confirm proper pump operation.
Check pump strainers for cleanliness.
ANNUALLY
Check operating control and other electrical components for proper operating procedures
as specified in manufacturers instructions.
The vessel and piping should be checked annually and the pump(s) inspected thoroughly.
An operational test should be performed and system checked as in start-up procedures
before staring the new heating season.
3.7 IDLE BOILER CARE AND LAY-UP
GENERAL
Corrosion damage to boilers is often the result of improper lay-up during non-operating periods.
Substantial damage can occur in only a few days if proper precautions are not taken. This
damage is irreversible and will reduce boiler reliability, increase maintenance costs and eventually
shorten the useful life of the boiler system.
