Vitocrossal 300, CT3 Series Operating

Important Regulatory and Safety Requirements

H Operation
Before operating the boiler, make sure you fully
understand its method of operation. Your heating
contractor should always perform the initial start-up and
explain the system.
Any warranty is null and void if these instructions are not
followed.
H Working on the equipment
All personnel working on the equipment or the heating
system must have the proper qualifications and hold all
necessary licenses.
Ensure main power to equipment, heating system, and
all external controls has been deactivated. Close main oil
or gas shut-off valve. Take precautions in all instances to
avoid accidental activation of power during service work.
H Dangerous conditions
– Deactivate main power immediately.
– Close main gas or oil shut-off valve.
H Gas smell
Follow the instructions on the front page of this manual.
H Flue gas smell
– Deactivate heating equipment.
– Open windows and doors.
– Inform your heating contractor.
CAUTION
Incomplete combustion and poisonous gases result if
the fresh air intakes in the mechanical room are closed.
Never close these openings.
H Combustion air and ventilation air openings
Ensure that combustion air openings and ventilation air
openings in the mechanical room are open.
H 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

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.
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.
