Crown Bermuda BSI069 in practice
The Bermuda BSI069 is a legacy cast-iron, natural-draft gas steam boiler rated at 69 MBH input with 57 MBH heating capacity and an AHRI net steam rating of 43 MBH (179 sq ft) at 82% AFUE per the BSI Space Heating Ratings table in the hosted 980433 Rev 12 I&O manual. It is built on 3 cast-iron sections with 5.1 gallons of boiler water.
The boiler measures 12-3/4" wide × 28" deep × 40-7/16" high with a 4" vent connection and an approximate shipping weight of 350 lb. The BSI IOM's rating table is headed 'Natural and LP Gas' with footnote 1 restricting use to altitudes at or below 2,000 ft in either fuel; BSI241 and BSI276 are marked as available semi-packaged. The line appears only in the frozen crownboiler.com legacy navigation and is superseded by the current Bermuda 2 (BSIB), which the official page says 'has many of the same features as the existing Bermuda (BSI)'.
Boilers.ca documents this size at model level from the hosted legacy manual; productStatus is 'discontinued'. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'; installation, gas, combustion and venting work belongs with a licensed contractor.
Best suited to
- Owners documenting an installed Bermuda (BSI) against the legacy ratings table (43 MBH net steam)
- Service planning for legacy cast-iron natural-draft steam boilers
- Replacement research comparing BSI sizes with the current Bermuda 2 (BSIB)
