Steam boiler maintenance checklists for the quarterly and annual rounds: 2 free lists, 11 items and 18 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against ASME boiler and pressure equipment; the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Steam boiler quarterly maintenance checklistquarterly
- Every quarter, weighted into the heating season while the boiler is making steam and carrying load. Run by: The boiler operator or service tech on the quarterly steam-plant round.
- Steam boiler annual maintenance checklistannual
- Once a year, timed with the jurisdictional inspection so the boiler can be opened, serviced and presented for the certificate in one shutdown. Run by: The boiler service lead runs the service; the jurisdictional or insurance inspector performs the certificate inspection, which is observed and recorded.
What most often fails on a steam boiler
- Gauge glass never blown down, so the level shown is a stuck column and the true water level is anyone's guess.
- Low-water cutoff trusted rather than tested, until a low-water event proves it was seized and the burner never cut out.
- Blowdown skipped and treatment left to run down, so dissolved solids climb and the boiler starts carrying water over into the steam lines.
- Water-side opened but scale and pitting noted only in passing, so a treatment problem that's thinning the sheet metal isn't tracked year to year.
- Controls tested one at a time but the full low-water and flame-failure lockout sequence never proven to actually shut the burner down and hold it out.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which steam boiler maintenance rounds do these checklists cover?
- Steam boiler quarterly maintenance checklist (quarterly): Every quarter, weighted into the heating season while the boiler is making steam and carrying load. Steam boiler annual maintenance checklist (annual): Once a year, timed with the jurisdictional inspection so the boiler can be opened, serviced and presented for the certificate in one shutdown.
- Who runs the steam boiler maintenance round?
- The boiler operator or service tech on the quarterly steam-plant round. The boiler service lead runs the service; the jurisdictional or insurance inspector performs the certificate inspection, which is observed and recorded.

- Which standards is steam boiler work verified against?
- ASME boiler and pressure equipment, published by the American Society of Mechanical Engineers. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (11 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
