Description
Rinnai Tankless Rack Systems (TRS) include wall mounted and free standing configurations. The wall mounted
rack systems are available for 2 or 3 water heaters. Free standing rack systems are available for 2, 3, 4, 5, or 6
water heaters.
The TRS can be ordered with Rinnai's Common Venting System, which consists of the CVent exhaust venting and
PP or PVC intake venting. Up to eight tankless units can share the same CVent system.
The Rinnai TRS features design details that make installation simple and straightforward.
•
Maneuverability: Fits, fully assembled, through standard 32-inch doorways and on elevators
•
Flexibility: Available in both wall-mount or freestanding design for indoor and outdoor installations.
•
Preassembled Gas and water manifolds are properly sized to maintain optimum performance.
•
The racks are constructed of powder-coated aluminum, powder coated steel, and stainless to stand up to the
most demanding commercial environments, while minimizing weight.
•
Optional electronic controls to obtain turn down ratios of up to 327:1 (Sold Separately).
NOTE: The TRS is designed to be used with Rinnai tankless water heaters only. Do not mount non-Rinnai water
heaters on the TRS.
