WATER PIPING - MIXING VALVE USAGE

Mixing Valves

DANGER
HOT
HOT
BURN
Water heated to a temperature which satisfies space
heating, clothes washing, dish washing, and other
sanitizing needs can scald and cause permanent injury
upon contact. Short repeated heating cycles caused by
small hot-water uses can cause a temperature increase of
the hot water by 20F° higher than the heater's temperature
settings.

Water temperature over
125°F can cause severe
burns instantly resulting in
severe injury or death.
Children, the elderly and the
disabled and are at highest
risk of scald injury.
Feel water before bathing or
showering.
Temperature limiting devices
such as mixing valves must
be installed when required
by codes and to ensure safe
temperatures at fixtures.

This appliance has been design certified as complying
with American National Standard/CSA Standard for water
heaters and certain models with side plumbing connections
are considered suitable for Water (Potable) Heating and
Space Heating.
Note: Do not use in space heating only applications.
The water supply pressure should not exceed 80 psi. If this
occurs, a pressure reducing valve with a bypass should be
installed in the cold water inlet line. This should be placed
on the supply to the entire house in order to maintain equal
hot and cold water pressures.
