Steam boiler annual maintenance checklist
The annual steam boiler service is the deep pass: the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against ASME boiler and pressure vessel code, manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The boiler service lead runs the service; the jurisdictional or insurance inspector performs the certificate inspection, which is observed and recorded.
When in the schedule
Once a year, timed with the jurisdictional inspection so the boiler can be opened, serviced and presented for the certificate in one shutdown.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as is, or load it into RTI and let the gate enforce it.
Pressure vessel and internals
- 3 photos
Water-side opened, inspected for scale and corrosion
Handhole and manway covers pulled, waterside surfaces inspected for scale, pitting and grooving, deposits documented and treatment adequacy assessed.
- 2 photos
Fire-side surfaces cleaned and inspected
Tubes and passages brushed to bare metal where reachable, soot and scale thickness noted, no cracking or overheating damage at the sheet.
Controls and safeties
- 2 photos
Low-water cutoffs opened, cleaned and tested
Float or probe cutoffs disassembled, cleaned of mud and scale, float chamber flushed, then proven to trip the burner on falling level.
- 1 photo
Full flame-failure and limit lockout sequence proven
A simulated fault drives the burner into lockout and it stays out until reset, operating and high-limit pressure controls each tripping at setpoint.
Certificate inspection
- 2 photos
Jurisdictional inspection observed and documented
The inspector's findings recorded, any required repairs captured with photos, and the certificate outcome logged. The inspector certifies the boiler, not the RTI user.
What usually sends this back
The failures are almost always the evidence, not the work
- 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.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 10 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.

Common questions
- What does this steam boiler annual checklist cover?
- 5 items across 3 sections, covering pressure vessel and internals, controls and safeties, certificate inspection. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- The boiler service lead runs the service; the jurisdictional or insurance inspector performs the certificate inspection, which is observed and recorded.
- When in the schedule should this walk happen?
- Once a year, timed with the jurisdictional inspection so the boiler can be opened, serviced and presented for the certificate in one shutdown.
- Why does every item ask for a photo?
- 10 of the 5 items call for photo evidence. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a steam boiler annual inspection?
- 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.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper-evident audit trail.
