Possible Causes

Intermittent flame failure, marginal pressure switch, overheating, sensor wiring issues

Safety first: Do not repeatedly reset a locking-out boiler without finding the cause.

Steps:

Record patterns: Note when lockouts occur (start-up, mid-run, windy conditions, etc.).
Inspect sensors: Check all temperature and pressure sensors for secure connections.
Clean flame sensor and burner: Improve flame stability by cleaning.
Have a technician review: A professional should access diagnostic history in the Peerless control and correct the underlying issue.
