Operation/Additional Safety Requirements

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.
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.
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.
Ensure the mechanical room and the
hot water heating boiler itself is kept
clean.
CAUTION
There are no user-serviceable
components on the boiler, burner,
control or on the heating system.
Contact a qualified heating
contractor for service!
WARNING
5167 482 v1.2
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
theriskoffrozenpipes.
