Takagi 110c Installation Manual And Owner's Manual page 8

• Installation and service must be performed by a qualified installer (for example, a
licensed plumber or gas fitter). Otherwise, the warranty will be void.
• The installer (licensed professional) is responsible for the correct installation of the
water heater and for compliance with all national, state/provincial, and local codes.
WARNING
• The manufacturer does not recommend installing the water heater in a pit or
location where gas and water can accumulate.
• Do not have the vent terminal pointing toward any operating window, door, or
opening into a building.
• Do not install next to any source of airborne debris, such as a clothes dryer, that can
cause debris to be trapped inside the combustion chamber.
• Do not install the unit where water, debris, or flammable vapors may get into the flue
terminal or the air intake line.
• The manufacturer does not recommend installing the water heater in an attic due
to safety issues. If you install the water heater in an attic:
• Make sure the unit will have enough combustion air and proper ventilation.
Failure to do so could lead to carbon monoxide poisoning or death.
• Keep the area around the water heater clean. When dust collects on the flame
sensor, the water heater will shut down on an error code.
• Place the unit where it will allow easy access for service and maintenance.
• A drain pan, or other means of protection against water damage, is
recommended to be installed under the water heater in case of leaks.
• The water heater must be securely mounted to a wall or other suitable structure.
• Failure to observe these warnings could result in severe personal injury, death,
and/or property damage.
• The warranty will not cover damage caused by water quality.
• Only potable water can be used with this water heater. Do not introduce pool
NOTICE
or spa water, or any chemically treated water into the water heater.
• Water hardness levels must not exceed 7 grains per gallon (120 ppm) for
single family domestic applications or more than 4 grains per gallon (70 ppm)
for all other types of applications. Water hardness leads to scale formation
and may affect/damage the water heater. Hard water scaling must be avoided
or controlled by proper water treatment.
• Water pH levels must be between 6.5 and 8.5
• Well water must be treated.
• The manufacturer recommends direct venting when the water heater is installed
in beauty salons, dry cleaners or any other locations in which such chemicals
are present in the air. Some chemicals used in beauty salons or dry cleaners may
affect the flame sensor. In such cases, the water heater may not work properly.
• Although the water heater is designed to operate with minimal sound, the
manufacturer does not recommend installing the unit on a wall adjacent to a
bedroom, or a room that is intended for quiet study or meditation, etc.
• Locate your heater close to a drain where water leakage will not do damage to
surrounding areas. As with any water heating appliance, the potential for leakage
at some time in the life of the product does exist. The manufacturer will not be
responsible for any water damage that may occur. If you install a drain pan under
the unit, ensure that it will not restrict the combustion air flow.
