Don't forget boiler room basics.
Responsible maintenance will lower your fuel costs, reduce breakdowns and extend the life of your equipment. Regularly scheduled maintenance check-ups and annual overhauls help to ensure dependable, efficient operation, even on the coldest day of the year. For example, a quarter-inch buildup of soot can reduce efficiency by one-third. Annual boiler cleanings can reduce your fuel costs by as much as 33 percent.
The following maintenance tips apply to commercial boilers with air/oil atomizing burners only, and Castle always recommends that only qualified personnel should operate, adjust or repair the equipment:
* Inspect the boiler room for oil or water leaks. Keep the room clean.
* Check the oil level in the air compressor or gear housing and fill if necessary. Be sure to use the correct lubricating oil.
* Check sight glass on the pre-heater to make sure there is no oil present.
* Look through the observation port of the combustion chamber to see if there is any carbon build-up or smoke.
* Check all burner linkages to be sure there has been no change from their original marked position. If there have been changes, the linkages need tightening.
* Check the water level in the boiler. Excessive loss may mean leaking boiler tubes, or a leaking steam or return line.
* Check the oil strainers daily and clean when necessary.
* Check the domestic hot-water temperature.
* Check the fuel-oil temperature gauges. (#6 oil only)
* Check oil gauge/inventory to monitor consumption and ensure proper inventory. Keep a daily inventory record.
* (For Rotary Burners) Check the atomizing cup and air nozzle daily. Never use a sharp instrument when cleaning. If damaged, replace the cup or nozzle.
Once a week, qualified personnel should:
* Open the blow-down valve of the low water cut-off while the burner is running. The burner should shut down when the water level drops in the glass, showing that the low-water cut-off is operating properly. This also removes rust and dirt from the float chamber.
* Check the weather-control settings.
* Check and clean the air filters.
* Check the boiler tubes for soot or water leaks.
* Check the boiler sight-glass, and clean if necessary.
* Visually inspect operating controls.
* The cover on the doors must be kept closed.
* Flush the below water line pre-heater.
* Observe the operation of draft controls.
* Observe the burner operation.
* Check the accuracy of the oil tank gauge by comparing it to a stick reading.
These tips are just part of what should become a daily, weekly, monthly and annual maintenance schedule. Castle Oil's complete Burner and Boiler Maintenance Checklist is available on the Internet at www.castleoil.com, or by calling Castle's Customer Care Center at (914) 381-6600 or (718) 823-8800.
