Series facts
The BSI Space Heating Ratings table prints 82.0% AFUE on BSI069B/103B/138B, 82.1% on BSI172B/207B and 82.2% on BSI241B/276B; the page and lit sheet headline 'Up to 82.2% AFUE'.
The Bermuda 2 (BSIB) is Crown's current gas-fired steam boiler, listed under Residential Boilers – Residential Gas on velocityboilerworks.com. The product page introduces it as 'The Bermuda 2 Gas-Fired Steam Boiler', notes that it 'has many of the same features as the existing Bermuda (BSI)', and headlines seven sizes from 69 to 276 MBH, up to 82.2% AFUE, a standard natural-gas build with an LP conversion kit, and optional near-boiler piping kits. The lit sheet adds a cast-iron heat exchanger, stainless steel burners, a built-in draft diverter to fit low spaces, an automatic vent damper, a fully assembled and rugged jacket, installation on combustible floors, and the positioning 'For residential and small commercial applications with approved chimney'.
The BSI Space Heating Ratings table covers seven models — BSI069B (69 MBH input, 57 MBH DOE heating capacity, 179 sq ft / 43 MBH AHRI net steam, 82.0% AFUE), BSI103B (103/84/263/63, 82.0%), BSI138B (138/113/354/85, 82.0%), BSI172B (172/142/446/107, 82.1%), BSI207B (207/171/533/128, 82.1%), BSI241B (241/199/621/149, 82.2%) and BSI276B (276/229/717/172, 82.2%) — with net steam ratings based on a piping and pickup allowance of 1.333, over 3–9 cast-iron sections, boiler water volumes of 5.1–13.5 gallons, steamable water volumes of 1.2–3.0 gallons (normal water level to low-water cutoff) and approximate shipping weights of 350–760 lb. Dimensions are 12-3/4"–32-1/4" wide × 28" or 30" deep × 40-7/16" high.
The near-boiler piping kits (113164-01 for 069–172, 113164-02 for 207–276) are designed to help deliver 'dry' steam, reduce short cycling, eliminate water hammering and protect against system flooding per the lit sheet. Boilers.ca documents all seven models at model level from the lit sheet and the 113113-02 I&O manual; no official Canadian-sales statement was found, so canadianStatus stays 'unknown', and gas, combustion and venting work belongs with a licensed contractor.
