Steam boiler maintenance checklists
Steam boiler maintenance checklists for the quarterly and annual rounds: 2 free lists, 30 items and 30 photo requirements, each item naming what to look for and the photo evidence it needs. Work is commonly verified against ASME boiler and pressure equipment; the edition in force is the AHJ's call on each project.
The steam boiler rounds
Where each walk sits in the schedule
01quarterly
Steam boiler quarterly maintenance checklist
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.
02annual
Steam boiler annual maintenance checklist
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.

- 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 (30 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.
Run these lists with the Photo Gate.
Tag one area, scan it, and the submit stays locked until the photos exist.
