Ideal Heating Commodore Wall Cascade

The Commodore Wall Cascade packages the Commodore Wall boilers on configured racking. The official page publishes rack configurations built from 2 to 6 boilers, with total inputs from 598 MBH (two CB299W) up to 3,000 MBH (six CB500W) and total outputs from 578 to 2,808 MBH. Rack systems are listed with 3-inch or 4-inch headers, depths of 27 or 28 inches, widths of 43 to 130 inches for the rack alone (up to 145 inches with the optional low-loss header), and rack weights of 325 to 1,130 lb before boilers.

Each configuration is identified by a rack code — RS0600BL2D3 through RS3000BL6D4 — and the page states modulation up to 39:1 across a cascade, rack heights of 66 inches (75 inches with the optional LWCO standpipe accessory), and a design basis of 30°F ΔT at a maximum velocity of 5.21 ft/s. A matched low-loss header is available as an option, and pump kits are listed for the racks.

The cascade page is documented by the Commodore Cascade submittal sheet and sales brochure. Because the rack is built from the Commodore Wall boilers documented separately on Boilers.ca, the same Canadian-availability caveat applies: no explicit Canadian sales statement was found on the official pages checked on 2026-09-09, so canadianStatus is recorded as unknown.
