Reference number
II-1264711-2021 (#24310)

Location: Surrey

Regulated industry sector: Gas – Natural Gas System

Incident overview

A water heater in a commercial building caught fire. It is very likely that due to the non-compliant installation of the oversized venting system serving the water heater, residue built up in the venting over time and caused the heater’s burner flame to roll out of the appliance, igniting the fire.
