Ruud AP13370-2 Water Heater User Manual


 
Installing the water heater.
This water heater must be installed in accordance with these instructions, local codes, utility company
requirements, and/or in the absence of local codes, use the latest edition of the American National
Standard/National Fuel Gas Code. A copy can be purchased from either the American Gas Association, 400
N. Capitol Street NW, Washington, DC 20001 as ANSI standard Z223.1 or National Fire Protection
Association, 1 Batterymarch Park, Quincy, MA 02269 as booklet NFPA 54. Or in Canada, CAN/CSA B149 -
Natural Gas and Propane Installation Code. A copy can be purchased from the Canadian Standards
Association, 5060 Spectrum Way, Mississauga, Ontario, Canada L4W 5N6.
Location
The water heater should not be located
in an area where leakage from the tank
or connections will result in damage to
the area adjacent to the heater or to
lower floors of the structure.
When such areas cannot be avoided it is
recommended that a suitable catch pan,
adequately drained, must be installed
under the water heater.
The pan must not restrict the lower air
inlet box located around the lower
perimeter of the water heater.
Catch pan kits are available from the store
where the water heater was purchased, or
any water heater distributor.
A gas fired water heater or any other
appliance should not be installed
in a space where liquids which give off
flammable vapors are to be used or stored.
Such liquids include gasoline, LP gas
(butane or propane), paint or adhesives
and their thinners, solvents or removers.
Because of natural air movement in a
room or other enclosed space, flammable
vapors can be carried some distance from
where liquids which give off flammable
vapors are to be used or stored. The open
flame of the water heater’s pilot or main
burner can ignite these vapors.
The water heater must be located so it is
not subject to physical damage, for example,
by moving vehicles, area flooding, etc.
For these reasons installation of a gas fired
water heater in a garage is not desirable.
Make certain the floor underneath the
water heater is strong enough to
sufficiently support the weight of the
water heater once it is filled with water.
If local codes require the use of a stand kit
to raise the water heater 18” (46cm) above
the floor, please contact the store where the
water heater was purchased, or any water
heater distributor. These kits must comply
with local codes.
The water heater should be installed as
close as practical to the gas vent or
chimney.
Long hot water lines should be insulated
to conserve water and energy.
The water heater and water lines should
be protected from exposure to freezing
temperatures.
Do not install the water heater in
bathrooms, bedrooms, any occupied
rooms normally kept closed, or in
unprotected outdoor areas.
Minimum clearance from combustible
construction is 0” (0cm) sides, 0” (0cm)
rear; and 3” (7.6cm) from the front of
the control. If the clearances stated on
the Instruction/Warning Label, located
on the front of the heater differ, install
the water heater according to the
clearances stated on the label.
The water heater may be installed on
combustible floors, but not directly on
carpeting. If the water heater must be
installed on carpeting, place a metal or
wood panel beneath the water heater,
extending beyond its full width and
depth at least 3” (7.6cm) in all
directions.
If the water heater is installed in an
alcove or closet, the entire floor must
be covered by a wood or metal panel.
A minimum of 24” (61cm) clearance
from the front and top should be
available for adequate inspection and
servicing.
The auxiliary catch pan
installation MUST conform
to local codes.
