CONSUMER SAFETY ALERT

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.
