Vitotronic 100, KW10A Operating and User's Information
Service Notice for your Heating System
We strongly recommend that you have your heating system checked and serviced by a qualified heating contractor on
an annual basis to ensure a safe and energy efficient operation.
A service contract is advisable.
Boiler
Every boiler must be cleaned within certain time frames.
A lack of cleaning causes soot build-up in the combustion
chamber which raises the flue gas temperature and
reduces the efficiency of your heating system.
System
Ensure that a qualified heating contractor checks all
system components such as the expansion tank, the
pressure relief valve, the pump(s), the zone valves, the
low water cut-off and all other system componentry
regularly.
Additional Safety Requirements
Carbon monoxide
The U.S. Consumer Product Safety Commission strongly
recommends the installation of carbon monoxide detectors
in buildings in which gas-burning equipment is installed.
Carbon monoxide (CO) is a colorless, odorless gas, which
may be produced during incomplete combustion of fuel
and/or when the flame does not receive an adequate
supply of combustion air.
Carbon monoxide can cause severe personal injury or loss
of life.
Therefore, carbon monoxide detectors that are in
compliance with a nationally recognized standard (e.g.
ANSI/UL 2034-2002, CSA 6.19-01) should be installed
and maintained in buildings that contain gas-burning
equipment.
Note: Viessmann does not test any detectors and makes
no representation regarding any brand or type of
detector.
CAUTION
Ensure the mechanical room and the hot water heating
boiler itself, is kept clean.
WARNING
The are no user-serviceable components on the boiler,
burner, control or on the heating system. Contact a
qualified heating contractor for service!
Frozen water pipe hazard
Your heating boiler is designed to provide a warm and
comfortable living environment. It is NOT designed to
ensure against freezing of water pipes.
The boiler is equipped with several safety devices that
are designed to shut down the boiler and to prevent it
from restarting in the event of various unsafe conditions.
If your boiler remains off for an extended period of time
during cold weather, water pipes may freeze and burst,
resulting in extensive water damage and conditions in
which mold could grow. Certain molds are known to
cause respiratory problems, as well as to pose other
serious health risks. In case of water damage, immediate
measures should be taken to dry out affected areas as
quickly as possible to prevent mold from developing.
If your home will be unattended for an extended period of
time during cold weather, you should...
Shut off the water supply to the building, drain the water
pipes and add an antifreeze for potable water to drain
traps and toilet tanks. Open faucets where appropriate.
or
Have someone check the building frequently during cold
weather and call a qualified service agency if required.
or
Install a reliable remote temperature sensor that will notify
somebody of freezing conditions within the home.
WARNING
Failure to protect against frozen pipes could result in burst
water pipes, serious property damage and/or personal
injury. Boiler may shut down. Do not leave your home
unattended for long periods of time during freezing
weather conditions without turning off the water supply
and draining water pipes or otherwise protecting against
the risk of frozen pipes.
