Ideal Commodore Wall CB470W in practice
The CB470W steps the Commodore Wall line up to 470 MBH maximum input with an 83 MBH minimum and a 5.7:1 turndown, producing 453 MBH output and a 394 MBH net AHRI rating. Its printed efficiency rows — 95.6% thermal and 95.1% combustion — include the highest thermal figure in the series.
It is one of the two larger Commodore Wall models that move to 6-inch vent/air connections; vent length is published at 200 feet. The chassis stays at 17.5 x 33.33 x 21.2 inches at 198 lb, with 2.7 gallons rated volume and the line's standard 1-1/2-inch supply/return and 1-inch gas connections. Modbus is standard, BACnet optional, and the unit is field-convertible between fuels.
Cascade racks that use the CB470W include the RS0940BL2D3 (two boilers, 940 MBH), RS1410BL3D3 (three boilers, 1,410 MBH) and larger configurations up to six boilers. 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
- Commercial plants between roughly 400 and 470 MBH per boiler
- Projects wanting the highest printed thermal efficiency in the Commodore Wall line
- Cascade racks that need 6-inch venting and 200-foot vent runs
