Ideal Commodore Floor CB3000F in practice
The CB3000F steps the Commodore Floor line into larger commercial plants at 3,000 MBH maximum input with a 420 MBH minimum and a 7.2:1 turndown. Output is 2,858 MBH with a 2,485 MBH net AHRI rating, and the printed efficiency rows are 99.0% thermal and 97.5% combustion — the second-highest thermal figure in the line.
The larger chassis measures 79 x 59 x 46 inches and weighs 1,984 lb with 34.6 gallons rated water volume, more than double the CB2000F. Connections step up to 4-inch Victaulic supply/return and 10-inch/12-inch vent/air, with 2-inch NPT gas and the line's 150-foot published vent length. Modbus is standard, BACnet optional, and the boiler is field-convertible between fuels.
Cascade capacity reaches 16 boilers, and the model is documented by the Commodore Floor manual set and the CB 3000–4000 submittal sheet. No explicit Canadian sales statement was found on the official pages checked on 2026-09-09; the Exalt and Gallant submittals list ANSI Z21.13 and CSA 4.9 compliance, so Boilers.ca records canadianStatus as unknown.
Best suited to
- Large commercial plants around 3,000 MBH per boiler
- Projects with 4-inch Victaulic headers and 10-inch/12-inch venting
- Plants where high water volume and 99% thermal efficiency are priorities
