Ruud RTG20218 Outdoor Recess Box Enclosure

Ruud RTG20218 Outdoor Recess Box Enclosure

The Ruud RTG20218 Outdoor Recess Box is a rough-in enclosure designed to house supply, gas, and venting connections behind the wall at the point where an outdoor tankless water heater or related equipment is mounted. Rather than leaving pipe stubs, shutoffs, and connectors exposed against an exterior wall, the recess box sets into the wall cavity during rough-in so the finished installation presents a clean, protected connection point once the appliance is hung. For plumbing contractors handling outdoor installs, a dedicated recess box like the RTG20218 keeps the rough-in organized and speeds up the trim-out stage because the connection points are already positioned and contained in a single enclosure.

Key Features

• Outdoor-Rated Design: Built as a recess box specifically intended for exterior wall installations, keeping rough-in connections protected from the elements at the mounting location.
• Recessed Mounting: Sets into the wall cavity so supply lines, shutoffs, and fittings sit flush rather than protruding, simplifying the final appliance hang.
• Centralized Connection Point: Consolidates the rough-in plumbing and related connections behind a single enclosure, reducing the number of exposed fittings a plumber has to route and support individually.
• Rough-In Ready: Intended for installation during the rough-in phase of new construction or a retrofit, ahead of drywall or exterior finish work, so the box is in place before the appliance is set.
• Ruud Brand Compatibility: Matched to Ruud equipment and installation practices, giving contractors a coordinated fit when working within the Ruud product ecosystem.
