Rinnai IP199S in practice
The IP199S is the largest I-Series+ solo, firing to 199,000 BTU/h of central-heating input for the line's maximum heating-only reach. It shares the large chassis (19.45 x 15.48 in) and 112.4 lb weight with the IP175S per both the product page and the English I&O manual, and like every solo it carries no DHW connections — hot water comes from an indirect tank.
This model is named in Health Canada recall RA-77507 (updated 2025-06-05): IP199S units sold between September 2024 and February 2025 with serial numbers beginning in S may have a boiler door that fails to seal, a carbon-monoxide hazard, with a free repair through Rinnai America at 800-621-9419.
Best suited to
- The maximum heating-only reach of the I-Series+ solo line: 199 MBH of input
- Large homes whose heat-loss calculation approaches 199 MBH, with DHW via an indirect tank
- Owners wanting the solo 15.6 sq ft heat exchanger at the top of the line
