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 minimum
clearance between the sides of adjacent
appliances because no service access is required
from the sides on most models. Note that high
kW input vertical square water heaters may have
an additional control access panel located on the
right side of the jacket requiring an additional
service access from the right side.
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.
