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.

Why Ruud?
Ruud is a long-established name in water heating equipment, and its recess box accessories are built to work alongside its outdoor appliance line to give installers a coordinated, professional-grade rough-in. Choosing a purpose-built recess box like the RTG20218 helps plumbers deliver a clean, organized connection point that supports a reliable long-term installation rather than an improvised exposed hookup.

Ruud RTG20218 – Frequently Asked Questions
1) What does the Ruud RTG20218 recess box actually do on an outdoor tankless water heater install?
The RTG20218 is a rough-in enclosure that sets into the wall cavity behind where an outdoor tankless water heater is mounted. It houses the supply, gas, and venting connections, along with shutoffs and fittings, so they sit contained in one box instead of stubbed out and exposed against the exterior wall. Once the appliance is hung, the connection point is protected and finished rather than improvised.
2) When in the job does the Ruud RTG20218 get installed?
During rough-in, ahead of drywall or exterior finish work. The box has to be set into the wall cavity before the wall is closed and before the appliance goes up, so it is not a trim-out item you add later. Plumbers who set it at rough-in get a faster trim-out because the connection points are already positioned inside the enclosure.
3) Is the Ruud RTG20218 only for new construction, or can I use it on a water heater replacement?
Both. The RTG20218 is called out for new construction plumbing rough-in as well as retrofit and replacement installations. On a retrofit the practical constraint is wall access: the box recesses into the cavity, so you need the exterior wall opened at the mounting location to set it.
4) What is the Ruud part number for the outdoor recess box so I can order the right one?
Order it as Ruud RTG20218. That is the manufacturer part number for the outdoor recess box enclosure, and it is the only model this enclosure is sold under.
5) Does buying the Ruud RTG20218 recess box get me the shutoffs and fittings too?
No. The RTG20218 is the enclosure itself, a box that contains the rough-in connections. The supply lines, gas piping, shutoff valves, connectors, and venting components are separate and get routed into the box by the installer, so plan those on the material list alongside it.
6) Can the Ruud RTG20218 be used on a commercial building or is it residential only?
It covers residential and light commercial outdoor equipment mounting. For a property manager or MRO buyer standardizing outdoor tankless installs across a portfolio, that means the same recess box part number works on single-family units and light commercial outdoor hookups alike.
