8
High heat sources (generating heat 100
o
F / 37
o
C or greater, such
as boiler ue pipes, space heaters, etc.) may damage plastic
components of the water heater as well as plastic vent pipe materials.
Such damages ARE NOT covered by warranty. It is recommended to
keep a minimum clearance of 8” from high heat sources. Observe
heat source manufacturer instructions, as well as local, state,
provincial, and national codes, laws, regulations, and ordinances
when installing this water heater and related components near high
heat sources.
4. Gas control system components must be protected from dripping
water during operation and service.
5. If the heater is to replace an existing heater, check for and correct
any existing system problems, such as:
• System leaks
• Location that could cause the system and heater to freeze and
leak
• Incorrectly sized expansion tank
6. Clean and ush system when reinstalling a heater.
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.
Locate the water heater where any leakage from the relief valve,
related piping, tank, or connections will not result in damage to
surrounding areas or lower oors of the building. The water heater
should be located near a oor drain or installed in a drain pan.
Leakage damages ARE NOT covered by warranty.
Failure of the water heater or components due to incorrect operating
conditions IS NOT covered by product warranty.
B. Leveling
In order for the condensate to properly ow out of the collection
system, the area where you locate the heater must be level. Location
must also fully support the weight of the lled water heater.
C. Clearances for Service Access
All water heaters eventually leak. It is recommended to install a catch
pan beneath the water heater. This catch pan should be sized with a
maximum depth of 2”, and a minimum diameter 2” greater than the
diameter of the water heater. The catch pan should empty into an
open drain line. This drain line should be 3/4” ID minimum, piped
to an open drain. Failure to follow these instructions could result
in property damage. Such damages ARE NOT covered by product
warranty.
Figure 2 - Minimum Service Clearances and Catch Pan Dimensions
NOTE: If you do not provide the minimum clearances shown in
Figure 2 it might not be possible to service the heater without
removing it from the space.
NOTE: A combustible door or removable panel is acceptable front
clearance.
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.
D. Residential Garage and Closet Installations
Precautions
If the heater is located in a residential garage, per ANSI Z223.1:
• Install the water heater burner and ignition devices a mini-
mum of 18” above the oor of the garage. This will ensure
the burner and ignition devices are well o the oor.
• When raising the water heater ensure the entire bottom and
fully lled weight of the water heater are fully supported.
• Locate or protect the water heater so it cannot be damaged
by a moving vehicle.
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.
