WARNING
Installation is not complete unless a pressure and
temperature relief valve is installed into the side of
the water heater. See the Water Connections section
of this manual for details.
This water heater contains very hot water under high
pressure. Do not unscrew any pipe fittings or attempt
to disconnect any components of this water heater
without positively assuring the water is cool and has
no pressure. Always wear protective clothing and
equipment when installing, starting up, or servicing
this water heater to prevent scald injuries. Do not
rely on the pressure and temperature gauges to
determine the temperature and pressure of the water
heater. This water heater contains components that
become very hot. Do not touch any components unless
they are cool.
Improper installation, adjustments, alteration,
service or maintenance can cause property damage,
personal injury or loss of life. Failure to follow all
instructions in the proper order can cause personal
injury or death. Read and understand all instructions,
including all those contained in component
manufacturer's manuals, which are provided with the
appliance before installing, starting-up, operating,
maintaining, or servicing this appliance. Keep this
manual and literature in legible condition and posted
near the appliance for reference by owner and service
technician.
This water heater requires regular maintenance and
service to operate safely. Follow the instructions
contained in this manual. Installation, maintenance,
and service must be performed only by an
experienced, skilled, and knowledgeable installer or
service agency.
CAUTION
The maximum boiler water supply temperature to
the indirect heat exchanger must not exceed 240°F
(116°C).
It is the responsibility of the installing contractor to
see that all controls are correctly installed and are
operating properly when the installation is complete.
DO NOT operate the water heater with jumpered
or absent controls or safety devices.
DO NOT tamper with or alter the water heater and/
or controls.
DO NOT operate the water heater if any external
part has been under water. Immediately call a
qualified service technician to inspect the appliance
and to replace any part of the control system that
was under water.
This water heater is suitable for installation on
combustible flooring. DO NOT install this water
heater on carpeting.
DO NOT operate this water heater without first
being certain it is filled with water.
Flammable items, pressurized containers, or any
other potential fire hazardous articles must never
be placed on or adjacent to the heater. Containers of
flammable gases should not be stored or used in the
same room with this water heater.
Hydrogen gas can be produced in an operating water
heater that has not had water drawn from the tank
for a long period of time (generally two weeks or
more). Hydrogen gas is extremely flammable. To
prevent the possibility of injury under these
conditions, we recommend that the water faucet be
opened for several minutes at the kitchen sink before
you use any electrical appliance that is connected to
the hot water system. If hydrogen is present, there
will be unusual sounds such as air escaping through
the pipes as hot water begins to flow. Do not smoke
or have open flame near the faucet at the time it is
open.
NOTICE
Insulation blankets are not required for this water
heater. This water heater meets or exceeds the
ASHRAE/IES 90.1b standards with respect to
insulation and standby loss requirements.
