3 Rinnai Rack Installation
DescripƟon
Rinnai Tankless Rack Systems (TRS) include wall mounted and free standing configuraons. The wall mounted
rack systems are available for 2, 3, or 4 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 Venng System, which consists of the CVent exhaust venng and
PVC intake venng Up to eight tankless units share the same CVent system.
The Rinnai TRS features design details that make installaon straighorward. Gas and water manifolds are
properly sized, and condensate drainage mechanisms and electronic controls for mulple units are included.
The racks are constructed of powder‐coated aluminum, to stand up to the most demanding commercial
environments, while minimizing weight.
The TRS is designed to be used with Rinnai tankless water heaters only. Do not mount non‐Rinnai water heaters
on the TRS.
