The IBC IFIRE-B is the condensing boiler branch of IBC's commercial IFIRE platform, offered in six sizes from 300,000 to 1,000,000 BTU/h with thermal efficiency up to 96.5%. The IFIRE itself is a volume water heater — a different product line — and both share the Raypak-platform I&O manual 241941 Rev. 13.
Series facts
IBC's IFIRE specification page prints 96.5% thermal efficiency for the IFIRE-B 300 and 96% for the 400, 500, 650, 800 and 1000 sizes.
IBC's Canadian IFIRE page presents two products: the IFIRE Volume Water Heater and the IFIRE B Condensing Boiler. Both have six models from 300,000 to 1,000,000 Btu/hr and achieve thermal efficiency up to 96.5%. The IFIRE-B sizes are IFIRE-B 300, 400, 500, 650, 800 and 1000.
The portal lists the IFIRE-B under "IFIRE-B Condensing commercial boiler". The shared installation and operation manual (241941) covers the H7 boiler 300B–1000B and the WH7 / IBGWSF1 / IVGWSF1 water heaters; it is a Raypak-platform document, and the VERSA IC controller manual (241493 Rev. 17) is the control reference. IBC's official IFIRE specification page (ibcboiler.ca/consumer/products/ifire/ifire-spec/) prints the SPECIFICATION – IFIRE B table with per-model CSA input, CSA output and thermal efficiency rows, and those printed rows are reproduced on the IFIRE-B model records here.
IBC positions the IFIRE platform for commercial new-construction and retrofit work with a stainless-steel water-tube option for heat and volume water heating. Because the IFIRE (volume water heater) and IFIRE-B (boiler) are different product lines with different functions, match the model prefix to the application when ordering parts or literature.

Services for IBC Technologies boilers
No. IBC sells the IFIRE as a volume water heater and the IFIRE-B as a condensing boiler; they are separate product lines, though both share the six-size 300,000–1,000,000 BTU/h range and the same I&O manual.
IBC's IFIRE specification page prints 96.5% thermal efficiency for the IFIRE-B 300 and 96% for the IFIRE-B 400, 500, 650, 800 and 1000, matching the platform's up-to-96.5% headline.
IBC's portal links the shared XFIIRE-IFIRE I&O manual, doc 241941 Rev. 13, which covers the H7 300B–1000B boilers and the WH7 water heaters; the VERSA IC controller is documented in 241493 Rev. 17.
