Hazard

Why it was recalled

The condensate dish inside the boiler can crack during a delayed ignition, allowing unburned gas to build up inside the sealed cabinet. If the gas ignites, the front cover can suddenly detach, posing a risk of serious injury or death from fire, carbon monoxide (CO) poisoning, and impact hazards.
Text from CPSC, unedited.

Incidents and injuries (CPSC): The firm has received 34 reported incidents of the condensate dish breaking, including three reports of the front cover detaching from the boiler. In one reported incident the technician servicing the boiler sustained a broken jaw.
