For your Safety

Working on the equipment

g
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 have been deactivated. Close main
gas supply valve. Take precautions in all instances to
avoid accidental activation of power during service
work.

Combustion air and ventilation openings

g
Ensure that combustion air openings and ventilation
air openings in the mechanical room are open.

Carbon monoxide

g
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.

Dangerous conditions

g
- Deactivate main power immediately
- Close gas supply valve
WARNING
This product burns gas to produce heat. The appliance
must be properly installed, operated and maintained
to avoid exposure to appreciable levels of carbon
monoxide and the installer is required to confirm that
at least one carbon monoxide alarm is installed in the
living space before the appliance is put into operation.
It is important for the carbon monoxide alarms to be
installed, maintained, and replaced following the alarm
manufacturer's instructions and applicable local codes.
IMPORTANT
Keep all literature in a safe place at the installation site.
Contact Viessmann for additional copies.

Frozen water pipe hazard

g
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.
