B. Leveling
In order for the condensate to properly flow out of the collection
system, the area where you locate the heater must be level. Location
must also fully support the weight of the filled water heater.
C. Clearances for Service Access
See Figure 1 and Table 5 for recommended service clearances. If these
minimum clearances are not provided, it may not be possible to service
the water heater without removing it from the space.
The space must be provided with combustion / ventilation air
openings correctly sized for all other appliances located in the same
space as the heater. The heater cover must be securely fastened to
prevent the heater from drawing air from the heater room. This is
particularly important if the heater is in a room with other appliances.
Failure to comply with the above warnings could result in substantial
property damage, severe personal injury, or death.

NOTE: When installing in a zero clearance location, it may not be
possible to read or view some product labeling. It is recommended to
make note of the heater model and serial number.
NOTE: A combustible door or removable panel is acceptable front
clearance.
MINIMUM CLEARANCES FROM COMBUSTIBLE MATERIALS
• Hot water pipes – at least 1" from combustible materials.
• Exhaust vent pipe – at least 1" from combustible materials.
Always take future maintenance into consideration when locating
the water heater. If the water heater is located in an installation
location with limited clearances, it may be necessary to remove the
water heater from the space to perform maintenance. Failure to
consider maintenance when determining installation location could
result in property damage.
D. Residential Garage and Closet Installations
Check with your local Authority Having Jurisdiction for requirements
when installing the water heater in a garage or closet. Please read
the entire manual before attempting installation. Failure to properly
take factors such as venting, piping, condensate removal, and wiring
into account before installation could result in wasted time, money,
and possible property damage and personal injury.

Precautions
If the heater is located in a residential garage, per ANSI Z223.1:
• Mount the bottom of the water heater a minimum of 18"
above the floor of the garage to ensure the burner and
ignition devices are well off the floor.
• Locate or protect the water heater so it cannot be damaged
by a moving vehicle.
The space must be provided with correctly sized combustion/
ventilation air openings for all other appliances located in the
space with the water heater. For power venting installations using
room air for combustion, refer to the venting section, this manual,
for descriptions of confined and unconfined spaces. Do not install
the water heater in an attic. Failure to comply with these warnings
could result in substantial property damage, severe personal
injury, or death.
