Why it was recalled

The boiler door can fail to seal properly due to incorrect screws, allowing carbon monoxide (CO) gases to escape, posing a carbon monoxide poisoning hazard.

Consumers should immediately stop using the recalled boilers and contact Rinnai to arrange to have a certified technician install the repair at no cost to the consumer.
