MIXING VALVE USAGE
Water (Potable) Heating: All models are considered suitable for
water (potable) heating only.
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 infirm,
or physically/mentally disabled. If anyone using hot water in your home
fits 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 satisfies 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 from your local plumbing
contractor. Consult a Qualified 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.
FACTS TO CONSIDER ABOUT THE LOCATION
Carefully choose an indoor location for the new water heater,
because the placement is a very important consideration for the
safety of the occupants in the building and for the most economical
use of the appliance.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed:
1. Select a location indoors as close as practical or centralized to
the water piping system as possible. The water heater should
be located in an area not subject to freezing temperatures.
2. Selected location must provide adequate clearances (4”) for
servicing parts such as the thermostats, drain valve, and relief
valve. Adequate clearance for servicing this appliance should be
considered before installation, such as changing the anodes, etc.
