February 14, 2025 — Noritz America, a leading provider of tankless water heaters and high-efficiency combination boilers, has unveiled a new series of five pre-assembled manifold and rack kits to provide a faster, easier way for contractors to build their own wall-hung or floor-mounted water heater solutions on commercial job sites. The goal: To make tankless water heating a compelling option for installers and end users, whether the application is for new construction or even emergency storage-tank water heater replacement.

Designed, engineered, and assembled by Noritz in its own U.S. facilities, the new CMK Manifold and CRK Rack Kits offer all the components needed to fabricate a floor-standing or a wall-hung system for tankless water heaters.

CMK: The Commercial Manifold Kit is available in three wall-hung configurations for supporting either two (Model No. CMK-SS2), three (-SS3), or four (-SS4) Noritz NCC199CDV commercial condensing tankless water heaters, which must be purchased separately. The kit includes the following pre-assembled items:
- two-inch hot-water copper manifold
- two-inch cold-water copper manifold
- two-inch black-iron gas manifold
- three-quarter-inch PVC condensate manifold
- two wall-mounting brackets
All other necessary components — sweated and threaded fittings, flexible connectors, bolts, etc. — are flat-packed with the manifolds and brackets in a single box that contractors will find easy to transport and carry onto a job site.
CRK: The Commercial Rack Kit is available in two floor-standing configurations: the CMK-BB2 for handling two NCC199CDV units and the CMK-BB4 for mounting three or four NCC199CDV units.

For floor-standing applications, an installer would receive two boxes: one containing all the manifold and component materials for assembling either the BB2 or the BB4 configuration; and a second box containing a set of lightweight but rugged aluminum frames for creating the base to mount the entire assembly.
