HOTTER
WATER
CAN SCALD:
VVater heaters
are intended
to produce
hot water.
Water heated
to a temperature
which
will
satisfy
space
heating,
clothes
washing,
dish washing,
cleaning
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
handicapped.
Ifanyone
using hotwaterin
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, shall 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,
see
Figure
14 below.
Valves
for
reducing
point of use temperature
by mixing
cold and hot water
are also
available.
Follow
manufacturer's
instructions
for
installation
of the valves.
Before
changing
the factory
setting
on the thermostat,
read the Temperature

Louvers
and Grilles:
In calculating
free area,
consideration
shall
be given
to the blocking
effect
of louvers,
grilles
or
screens
protecting
openings.
Screens
used
shall
not be
smaller
than
1/4 inch (6.4 mm) mesh.
If the free area through
a design
of louver
or grille
is known,
it should
be used
in
calculating
the size
opening
required
to provide
the free
area specified.
If the design
and free area is not known,
it
may
be assumed
that wood
louvers
will be 20-25
percent
free
area
and
metal
louvers
and grilles
will have
60-75
percent
free area.
Louvers
and grilles
shall
be fixed
in the
open
position
or interlocked
with the equipment
so that they
are opened
automatically
during
equipment
operation.
Special
Conditions
Created
by Mechanical
Exhausting
or
Fireplaces:
operation
of exhaust
fans,
ventilation
systems,

or fireplaces
may create
conditions
requiring
special
attention
to avoid unsatisfactory
operation
of installed
