Incident overview

The maintenance staff of a facility found smoke coming from a boiler where the fan inside the boiler cabinet had caught fire. The boiler manufacturer released a product upgrade notice for a new exchanger lid design in October 2022 and recommended it be installed at the next service. This boiler did not have the manufacturer's updated heat exchanger lid installed and had not received any annual service since its original installation in October 2021.
