Rinnai IP199199C in practice
The IP199199C is the largest I-Series+ combi: both sides of the appliance fire to 199,000 BTU/h, giving the line its maximum central-heating and domestic-hot-water reach. Weight and height come from the EN I&O manual spec table — 123.5 lb (56 kg) and a 34.88 in body height (37.87 in or 40.67 in overall with fittings) — against a product page that prints 64 lb and 45.3 in; both conflicts are recorded on the spec rows rather than resolved silently. The 9.8 GPM maximum DHW flow is printed on the product page and in the manual spec table alike.
This model is named in Health Canada recall RA-77507 (updated 2025-06-05): 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, and Health Canada directs owners to a free repair through Rinnai America at 800-621-9419.
Best suited to
- The largest central-heating loads the I-Series+ combi line serves, to 199 MBH of input
- Owners who want maximum heating and hot-water reach from one wall-hung appliance
- Large homes where an IP150199C or IP175199C would be undersized on the heating side
