Domestic Piping

The installer must install discharge piping onto the T&P relief valve. The discharge piping must be:

•Made of material serviceable for tem- peratures of 250ºF or greater.

•Directed so that any hot water dis- charge flows away from all persons.

•Directed to a suitable place of drainage.

•Installed as to allow complete draining of the T&P relief valve and the dis- charge piping.

•Terminated with a plain end, not with threads.

CAUTION

Failure to properly direct the discharge piping of the T&P relief valve may result in flooding of the area adjacent to the unit and or lower floors in the structure causing substantial property damage.

The installer must not install the T&P relief valve discharge piping in a manner that is:

•Excessively long: Using more than 2 elbows and/or 15 feet of discharge pip- ing can reduce the discharge capacity.

•Terminated directly into a drain: The discharge piping must terminate within 6 inches of the drain. Check with local plumbing codes for termination guide- lines.

•The discharge piping is plugged, reduced in size or restricted in any manner.

•The discharge piping is subject to freezing.

WARNING

DO NOT install any valves between the T&P relief valve and the discharge pip- ing. DO NOT plug the T&P relief valve or the discharge piping. Improper place- ment and piping of the T&P relief valve can cause severe personal injury, death or substantial property damage.

Thermostatic Mixing Valve

The PERFORMANCE PLUS contains a facto- ry installed thermostatic mixing valve with built-in check valve.

The operating range of the thermostatic mixing is 90ºF to 120ºF.

For applications with a domestic recirculation loop, the recirculation pump should be con- trolled by an aquastat. The maximum recom- mended setting of the aquastat is 10ºF lower than the thermostatic mixing valve setting.

DANGER

For proper operation of the thermostatic mixing valve and to prevent potential scalding hazards, the recirculation loop should be controlled by an aquastat. DO NOT use continuous recirculation.

U-Tube Assembly

The PERFORMANCE PLUS is supplied with a U-Tube Assembly that directs cold water to the thermostatic mixing valve.

To install the U-Tube Assembly the installer must:

1.Disconnect the cold inlet adapter/union from the thermostatic mixing valve.

2.Using needle-nose pliers remove the plastic check valve assembly from the adapter.
