What this means for you

Our severity reasoning: Carbon monoxide is a high-risk hazard that can cause serious harm or death if inhaled in sufficient quantities.

Plain-English summary

Rinnai America Corporation is recalling about 2,030 Rinnai i-Series Plus residential wall-mounted gas boilers (model numbers IP175S, IP199S, IP175199C, and IP199199C) sold nationwide through independent heating and plumbing contractors, wholesale distributors, Amazon.com, Home Depot, and Lowe's between September 2024 and February 2025 for $3,900 to $5,000 per unit.

The boiler door can fail to seal properly due to incorrect screws, allowing carbon monoxide (CO) gases to escape from inside the boiler. This creates a carbon monoxide poisoning hazard to occupants of the home. No injuries have been reported.

Consumers should immediately stop using the recalled boilers and contact Rinnai to arrange a free repair by a certified technician. Consumers who must continue using the boiler while awaiting repair should install working carbon monoxide alarms on each level of their home and outside sleeping areas.
