Installation Guide

• The water heater should be located in an area not
subject to freezing temperatures. Water heaters
located in unconditioned spaces (i.e., attics,
basements, etc.) may require insulation of the
water piping and drain piping to protect against
freezing. The drain and controls must be easily
accessible for operation and service. Maintain
proper clearances as specified on the data plate.
• Do not locate the water heater near an air-moving
device. The operation of air-moving devices such as
exhaust fans, ventilation systems, clothes dryers,
fireplaces, etc., can affect the proper operation of
the water heater. Special attention must be given to
conditions these devices may create. Flow reversal
of flue gases may cause an increase of carbon
monoxide inside of the dwelling.
CAUTION - PROPERTY DAMAGE HAZARD
The water heater should be located in an area
where leakage of the tank or connections will not
result in damage to the area adjacent to the water
heater or to lower floors of the structure. Due to the
normal corrosive action of the water, the tank will
eventually leak after an extended period of time. Also
any external plumbing leak, including those from
improper installation, may cause early failure of the
tank due to corrosion if not repaired. If the owner/
operator is uncomfortable with making the repair a
qualified person should be contacted. A suitable metal
drain pan should be installed under the water heater
as shown below, to help protect the property from
damage which may occur from condensate formation
or leaks in the piping connections or tank. The pan
must limit the water level to a maximum depth of
1-3/4” and be two inches wider than the heater and
piped to an adequate drain. NOTE: The pan must
not restrict combustion air flow. Locate the water
heater near a suitable indoor drain. Outside drains are
subject to freezing temperatures which can obstruct
the drain line. The piping should be at least 3/4” ID
and pitched for proper drainage.

NOTE: Minimum clearances from combustible materials
are stated on the data plate adjacent to the gas control
valve/thermostat of the water heater.
The water heater is certified for installation on a
combustible floor.
• IMPORTANT: If installing over carpeting, the carpeting
must be protected by a metal or wood panel beneath
the water heater. The protective panel must extend
beyond the full width and depth of the water heater
by at least 3 inches (76.2mm) in any direction or if in
a alcove or closet installation, the entire floor must be
covered by the panel.
WARNING
Fire Hazard
For continued protection
against the risk of fire:
Do not install water heater
on carpeted floor.
Do not operate water heater
if flood damaged.
• Figure 1 may be used as a reference guide to locate
the specific clearance locations. A minimum of 24
inches of front clearance and 4 inches on each side
should be provided for inspection and service.

NOTE: The water heater must be braced, anchored, or
strapped to avoid moving during an earthquake. Contact
local utilities for code requirements in your area or call
1-800-456-9805 and request instructions.
