TABLE - A
CLEARANCES FROM
COMBUSTIBLE CONSTRUCTION:
Right Side - 0"
Rear - 0"
Left Side - 0"
Front - 18" (45cm) for service access to controls and
heating elements
Top - 12" (30cm) suggested for service access to
piping and water connection
Hot Water Pipes 1" (25.4mm)
Maintain minimum specified clearances for adequate
operation. All installations must allow sufficient space for
servicing the electrical components, water pipe
connections, piping and other auxiliary equipment, as well
as the appliance.
Multiple appliances may be installed in a modular water
heater installation. Multiple appliances may be installed
side by side with no clearance between the sides of adjacent
appliance. This appliance is approved for zero clearance
from side combustible surfaces and no service access is
required from the sides on most models.
MOUNTING
The water heater should be mounted to the floor following
applicable architectural and local code requirements or
accepted standards for the specific site and model
purchased. In areas prone to seismic activity, it is
recommended that the water heater be mounted to the
floor according to recommended procedures for the site. In
some geographic areas, additional strapping or braces may
be required, consult local codes for specific requirements.
Proper mounting will help to make the water heater less
susceptible to seismic damage.

WATER CONNECTIONS
NOTE:
Before making any connections to the cold water
inlet or hot water outlet, insure that all piping is clean
and free of material or scale. This can usually be
accomplished by "blowing out the pipe." Any foreign
material or scale entering the water heater can
adversely affect operation and performance.
NOTE:
When using copper tubing, solder tubing to an
adapter before attaching to the threaded nipple
connection provided on the water heater. Soldering
directly to the threaded connection may harm a
lining in the nipple or damage the tank lining.
