12. Inspect burner assembly. Replace nozzle and filters on oil burning equipment.
Annually
Clean, check, and adjust electrodes.
Annually
13. Inspect internal and external heating surfaces after cleaning. Fireside surfaces
should be free of soot. Cracked surfaces will require repair or replacement of the
furnace (firing chamber). Repair to pressure parts requires a certified welder.
Evidence of bulges or other deformities indicate defective controls and safety
devices or improperly sized and adjusted burner. Consult a boiler water treatment
specialist if there is evidence of hard scale on the waterside surfaces.
14. Inspect gas piping and valves regularly for proper support and tightness. Test
Annually
for tightness with a soap solution. If a leak is detected, then secure the piping to
the boiler and contact the gas company.
15. Check the transformer. Do not interchange transformers of different capacities
Annually
when replacing defective transformers.
16. Inspect area around boiler for cleanliness, combustibles, etc. Remove trash
Annually
and any combustibles from the boiler room. Assure proper ventilation to the boiler.
17. Check draft, manifold pressure, and combustion. Conduct combustion
Annually
efficiency test and adjust burner for efficient and safe operation. Combustion
measurements required are for CO%, CO2%, 02%, stack temperature, and boiler
room temperature. No smoke or CO should be evident. Overfire draft should be
at least +5 Pa (+0.02 inches water gage) (W.G.) for oil burners. Adjust manifold
pressure as specified by the manufacturer.
Annually
18. Inspect control equipment for proper sequence and operation. Covers on
controllers should be in place. Dust and dirt on control equipment must be
removed. Electric contacts that are fouled require cleaning. All wiring should be
properly grounded.
Annually
19. Calibrate and check operation of gages and meters. Repair or replace all
defective gages and meters. Defects include cracked, broken, or dirty glass,
illegible markings, and bent pointers. Place date and initials of tester on the face
of the calibrated gages.
20. Check breaching and stack for integrity and tightness. Breaching and stack
Annually
should be firmly attached to the boiler in forced draft systems. The breaching and
stack should be properly supported and either vertical or sloped upward.
21. Check shell for cleanliness, excessive rust, corrosion streaks, or any
Annually
deformations and cracks. Clean and repair as necessary. Repaint to cover bare
metal. Assure access doors are in place and in working order.
22. Check fuel oil supply. Note level of oil tank. Leaking tanks must be repaired
Annually
or replaced immediately
