The Rinnai Tankless Rack System

The Complete Installation Solution for Multiple Units 

 Rinnai Ultra Series Condensing Tankless Water Heaters

 COMMERCIAL WATER HEATING

Simplified Installation for Banked Tankless Units.

The new Rinnai Tankless Rack System (TRS) offers commercial contractors a complete, reliable solution for multi-unit tankless installation. Designed and tested by Rinnai, the

TRS can be ordered, built, and shipped fully-assembled to any location in the United States and Canada, including the job site.

Installers save valuable installation time and avoid the costly, complicated process of building racks on site. Plus, the Rinnai-engineered system delivers the peace of mind of knowing every part of the tankless system is designed and built to work together seamlessly.

Flexible Installation, Indoors or Out

With a Rinnai TRS, installations can be wall-mounted or free-standing, to suit the application. Indoor installations can be configured with either individual, concentric venting or common venting. Exterior installations require no venting.

The fully assembled TRS is designed to fit through a standard 32-inch doorway, even with water heaters attached, for ease of movement and installation on the job site.

Available Common Venting Reduces Roof, Wall Penetrations

For even greater convenience and ease of installation, the TRS can be ordered with Rinnai’s Common Venting System, which consists of the CVent exhaust venting and PVC intake venting. Up to eight tankless units share the same CVent system, allowing longer vent runs and requiring a maximum of two terminations as compared to conventional venting.

Rinnai's Common Venting System supports vent runs of up to 100 feet for seven or fewer units. Eight units on a single system can be connected with up to 41 feet in vent length.

Engineered for Durability and Ease of Use

The Rinnai TRS features design details that make installation straightforward. Gas and water manifolds are properly sized, and electronic controls for multiple units are included.

The racks are constructed of powder-coated aluminum, to stand up to the most demanding commercial environments, while minimizing weight. And the entire system has been designed by Rinnai to ensure maximum safety and reliability.
