Field-record purpose

Commercial Boiler Seasonal Changeover: what the project record must preserve

The boiler changeover record organizes seasonal startup, isolation valves, pumps, expansion, air elimination, treatment, controls, staging, combustion and venting, outdoor-reset settings, occupied-space communication, leak inspection, temperatures, and open deficiencies. This page describes Sandison's documentation method and the evidence expected for this class of work. It does not identify a customer, publish a private address, or claim that every listed step occurred at one property unless an approved image and caption state that connection explicitly. Scope, access, code, equipment, and outcome remain tied to the actual work order.

Verification standard

The completion record distinguishes the approved work from the conditions left open

Useful evidence includes fault history, temperature rise or hydronic delta, static pressure or flow observations, combustion and vent condition as applicable, electrical readings, control sequence, and verified operation after correction. Comfort depends on heat loss, equipment capacity, return and supply air, pumps and zones, filters or coils, duct or piping condition, fuel, electrical supply, condensate, venting, controls, and the building envelope. A useful closeout identifies the original complaint, confirmed condition, authorized work, concealed or excluded items, photographs or readings, startup or flow checks, permit or inspection status where applicable, maintenance instructions, and any follow-up assigned to Sandison, the owner, a utility, restoration contractor, manufacturer, or another licensed discipline.
