Crown Boiler Co. · Series
The Bermuda (BSI) is Crown's legacy cast-iron, natural-draft gas steam boiler — seven sizes BSI069 through BSI276 from 69 to 276 MBH input and 43 to 172 MBH AHRI net steam at 82.0–82.2% AFUE — documented only in the frozen crownboiler.com 'Residential Gas' navigation and the still-hosted BSI I&O manual, and superseded by the current Bermuda 2 (BSIB).
Series facts
The BSI Space Heating Ratings table prints 82.0% AFUE on BSI069/103/138, 82.1% on BSI172/207 and 82.2% on BSI241/276.
The Bermuda (BSI) is Crown's legacy cast-iron gas steam boiler, documented in the frozen crownboiler.com 'Residential Gas' navigation as 'Bermuda Series (BSI)' and absent from the current Velocity Boiler Works menu. The legacy product page is an official shell with no body copy — it lists the hosted documents (the 980433 Rev 12 BSI I&O manual and the 109547-02 users information manual) — so Boilers.ca records the line from the hosted manual, whose cover titles it 'BSI Series — Gas-Fired Natural Draft Steam Boilers'.
The BSI Space Heating Ratings table (Table 2.2) covers seven models — BSI069 (69 MBH input, 57 MBH heating capacity, 179 sq ft / 43 MBH AHRI net steam, 82.0% AFUE), BSI103 (103/85/267/64, 82.0%), BSI138 (138/113/354/85, 82.0%), BSI172 (172/142/446/107, 82.1%), BSI207 (207/171/533/128, 82.1%), BSI241 (241/199/621/149, 82.2%) and BSI276 (276/229/717/172, 82.2%) — headed 'Natural and LP Gas', with 3–9 cast-iron sections, water volumes of 5.1–13.5 gallons and dimensions of 12-3/4"–32-1/4" wide × 28" or 30" deep × 40-7/16" high. Footnote 1 restricts use to altitudes at or below 2,000 ft in natural or LP gas; BSI241 and BSI276 are marked as available semi-packaged.
The current Bermuda 2 page states the new model 'has many of the same features as the existing Bermuda (BSI)', which is how the official site connects the two generations. Boilers.ca records the legacy Bermuda as productStatus 'discontinued' and documents all seven sizes at model level from the hosted manual; no official Canadian-sales statement was found, so canadianStatus stays 'unknown', and gas, combustion and venting work belongs with a licensed contractor.

Services for Crown Boiler Co. boilers
No — the Bermuda (BSI) appears only in the frozen crownboiler.com legacy navigation and is absent from the current Velocity Boiler Works catalogue, so Boilers.ca records productStatus 'discontinued'. It is superseded by the current Bermuda 2 (BSIB).
Seven: BSI069, BSI103, BSI138, BSI172, BSI207, BSI241 and BSI276 at 69, 103, 138, 172, 207, 241 and 276 MBH input, with 43–172 MBH AHRI net steam ratings and 82.0–82.2% AFUE per the BSI Space Heating Ratings table.
They are consecutive generations of the same Crown cast-iron steam boiler line. The current Bermuda 2 (BSIB) page states it 'has many of the same features as the existing Bermuda (BSI)'; the legacy BSI used model numbers without the B suffix (BSI069 style) while the Bermuda 2 uses BSI069B-style numbers.
