TYPICAL INSTALLATION
FIGURE 2.
MIXING VALVE USAGE
This appliance has been design certied as complying with American
National Standard for water heaters and is considered suitable for:
Water (Potable) Heating and Space Heating: All models are
considered suitable for water (potable) heating and space heating.
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a
temperature which will satisfy space heating, clothes washing, dish
washing, and other sanitizing needs can scald and permanently injure
you upon contact. Some people are more likely to be permanently
injured by hot water than others. These include the elderly, children,
the inrm, or physically/mentally handicapped. If anyone using hot
water in your home ts into one of these groups or if there is a local
code or state law requiring a certain temperature water at the hot
water tap, then you must take special precautions. In addition to
using the lowest possible temperature setting that satises your
hot water needs, a means such as a Mixing Valve, should be used
at the hot water taps used by these people or at the water heater.
Mixing valves are available at plumbing supply or hardware stores.
Consult a Qualied Installer or Service Agency. Follow mixing valve
manufacturer’s instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the “Temperature
Regulation” section in this manual, see Figure 21.
