Rinnai boilers in Canada

Rinnai Canada (rinnai.ca) sells the Japanese manufacturer's residential condensing boilers under the I-Series+ name: combi models with IP-prefixed codes such as IP060160C (central-heating input over DHW input) and heating-only "solo" models such as IP060S. Boilers.ca documents the boiler manuals only; Rinnai tankless water heaters are out of scope here.

About Rinnai

Rinnai's current Canadian residential boiler family is the I-Series+ condensing line, sold through rinnai.ca: combi boilers pair space heating with built-in on-demand domestic hot water, and heating-only solo boilers work with a separate indirect tank. Canadian model codes carry an IP prefix with two numbers — the central-heating input and the DHW input for combis (for example IP090199C means 90,000 BTU/h CH with 199,000 BTU/h DHW) — which differs from the US-style lowercase "i" codes, so Boilers.ca records each model under its Canadian code.

Rinnai also sells tankless water heaters on rinnai.ca, but those are out of scope on this gas-boiler site. The caution matters for fault codes: Rinnai tankless heaters and I-Series+ boilers both report short numeric diagnostic codes, and forum and web content frequently mixes the two. On the boilers, codes appear as plain numbers or letters (such as 021, 110, LC, FFF, SS) with no E prefix, and each code is documented in the boiler's own I&O manual with combi-only and solo-only rows marked — which is why code lookups on Boilers.ca are scoped to the boiler manuals.

Health Canada recall RA-77507 covers the four largest I-Series+ models — IP175S, IP199S, IP175199C and IP199199C — sold in Canada from September 2024 to February 2025 with serial numbers beginning in S: the boiler door could fail to seal, creating a carbon-monoxide hazard. Health Canada's alert (updated 2025-06-05) reports 249 units sold in Canada and 2,030 in the USA with no incidents as of 2025-05-13, and directs owners to a free repair through Rinnai America at 800-621-9419.

The older I-Series (Canadian codes i060CN/i090CN/i120CN combis and i060SN/i090SN/i120SN solos) and M-Series (M060CN through M160CN) product pages remain on rinnai.ca as orphaned, unlinked pages even though the models are no longer listed for sale; Boilers.ca documents them as discontinued history, with the current I-Series+ line as the only boiler family on the rinnai.ca navigation today.

Series

Rinnai boiler series

Each series hub lists its models, verified specifications, manuals and documented alerts.

  • Rinnai's Canadian I-Series+ combis put space heating and on-demand domestic hot water in one wall-hung condensing appliance: the five models up to 150 MBH input (IP060160C through IP150199C) are documented here in full from the EN I&O manual 800000190(02), and the two larger combis (IP175199C, IP199199C) are on rinnai.ca but only as draft models here, because their I&O content is raster-only pending review.

  • Rinnai's Canadian I-Series+ solo boilers are the heating-only members of the family: IP060S through IP150S fire 15,000 to 150,000 BTU/h with no built-in hot-water production and are documented here from EN I&O manual 800000191(02). The two large solos, IP175S and IP199S, are on rinnai.ca (IP175S marked available September 2024) but stay draft models here pending review of their raster-only manual.

  • The previous-generation Canadian I-Series used lowercase-i model codes with CN (combi-NG) and SN (solo-NG) suffixes: combis i060CN/i090CN/i120CN and solos i060SN/i090SN/i120SN/i150SN. Rinnai no longer lists these models for sale — the rinnai.ca product pages survive as orphaned pages with empty model grids, and Boilers.ca documents each code from the specs printed on those pages.

Its rinnai.ca pages remain as orphaned, unlinked product pages that still host the I&O and conversion manuals plus AHRI certificates, and Boilers.ca documents all eight codes from the spec rows printed on those pages.

Frequently asked questions

Is Rinnai's I-Series+ a combi or a heating-only boiler line?

Both, under one family. Combi models (codes ending in C, such as IP090199C) produce on-demand domestic hot water inside the boiler, while the heating-only "solo" models (codes ending in S, such as IP090S) heat the building and serve an indirect tank for hot water. Boilers.ca documents each model against its own manual.

Why does Boilers.ca ignore Rinnai tankless water heater fault codes?

Rinnai tankless heaters and I-Series+ boilers both show short numeric codes, but the codes are defined in different manuals and are frequently mixed up online. Boiler codes on this site come only from the boiler I&O manuals and appear without an E prefix; a tankless heater's E-code table is not applied to boilers.

Are the large I-Series+ models affected by a recall?

Health Canada recall RA-77507 covers the IP175S, IP199S, IP175199C and IP199199C models sold between September 2024 and February 2025 with S-prefix serial numbers, over a boiler-door seal that could fail. Health Canada lists a free repair through Rinnai America at 800-621-9419; owners should follow the official alert.
