Water Piping
When
communicating
with
the
outdoors
through
horizontal
ducts, each opening shall have a minimum free area of 1
square inch per 2,000 BTU per hour (11 cm^/kW) of total
input
rating
of
all
equipment
in
the
enclosure.
See
Figure 13.
When ducts are used, they shall be of the same cross
sectional area as the free area of the openings to which they
connect. The minimum short side dimension of rectangular
air
ducts
shall
not
be
less
than
3
inches
(76.2 mm). See Figure 13.
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.
Speciai
Conditions
Created
by
Mechanical
Exhausting
or
Fireplaces:
operation
of
exhaust
fans,
ventilation
systems,
clothes dryers or fireplaces may create conditions requiring
special attention to avoid unsatisfactory operation of installed
gas utilization equipment.
ADANGER
Water
temperature
over
125°F
(52°C)
can
cause
severe
burns
instantly resulting in severe injury
or death.
Children,
elderly,
and
the
physically
or
mentally
disabled
are at highest riskfor scald injury.
Feel
water
before
bathing
or
showering.
Temperature
limiting
valves
are
available.
Read instruction manual for safe
temperature setting.
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,
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
physicaily/mentaliy handicapped. 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, 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. 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 Regulation section in this
manual.
