CHAPTER 2 - DOMESTIC PIPING
• When the water supply pressure is higher than 70
psig, it is recommended to install a pressure reduc-
ing valve on cold water supply line to prevent wa-
ter loss through T&P relief valve.
2.12. Thermostatic Mixing Valve
The PRESTIGE Excellence is factory supplied with a ther-
mostatic mixing valve with built-in check valve. The
mixing valve must be installed as shown in
Fig. 3 below .
The operating range of the thermostatic mixing is 85ºF
[30ºC] to 150ºF [65ºC].
For applications with a domestic recirculation loop, the
recirculation pump should be controlled by an aquastat.
The maximum recommended setting of the aquastat is
10ºF lower than the thermostatic mixing valve setting.
For proper operation of the thermostatic
mixing valve and to prevent potential scald-
ing hazards, the recirculation loop should be
controlled by an aquastat. DO NOT use con-
tinuous recirculation.
Failure to comply with this instruction will re-
sult in serious injury, or death.
DANGER
2.13. Recirculation Piping
• Recirculation piping must be installed in the cold
water inlet as shown in Fig. 5 on page 7.
• A stainless steel or bronze circulator is recommend-
ed.
2.14. Storage Tank Application
For applications requiring large volumes of domestic
hot water in a relatively short period of time, the install-
er may include a storage tank (see
Fig. 6 on page 8 )
in the domestic piping.
The installer must:
1. Relocate the thermostatic mixing valve from the
PRESTIGE Excellence to the outlet of the storage
tank.
2. Provide recirculation from the storage tank back to
the PRESTIGE Excellence using a stainless steel or
bronze circulator. Maximum recommended recir-
culation flow rate is 1 gpm.
