Clearances and Accessibility
Notice: Minimum clearances from combustible
materials are stated on the data plate adjacent to the
thermostat of the water heater.
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 three inches (76.2mm) in any direction; or if in a
alcove or closet installation, the entire floor must be
covered by the panel.
Figure 2 may be used as a reference guide to locate
the specific clearance locations. A minimum of 24
inches of front clearance should be provided for
inspection and service.
!
The water heater is certified for installation on a
combustible floor.
Important: 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 homeowner is uncomfortable with making
the repair a qualified service technician 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. 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. Under no circumstances will the
manufacturer or seller of this water heater be held
liable for any water damage which is caused by your
failure to follow these instructions.

!
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, fire-places, 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.
!
If the water heater is located in an area that is
subjected to lint, dirt, and oil, it may be necessary
to periodically clean the Flame-trap (see “External
Inspection & Cleaning of the Flame-trap,” Page 22).
