For your Safety (continued)
Safety
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, CSA 6.19 latest edition) 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.
For safe operation
We recommend that you frequently:
- Check for debris which could obstruct the flow of
flue gases. The vent or chimney must not be blocked.
A blocked or partially blocked vent or chimney can
cause flue gases to leak into the structure.
Flue gases leaking into the house can cause injury
or loss of life. Blocked or partially blocked chimneys
must have the blockage removed by a qualified
heating contractor.
- Check pressure gage for correct system (water)
pressure. Check for water on the floor from the
discharge pipe of the pressure relief valve or any
other pipe, pipe joint, valve or air vent.
- Check for moisture, water, or appearance of rust
on the flue gas pipes, their joints as well as vent
dampers, or side wall vent terminals (if so equipped).
- Ensure that nothing is obstructing the flow of
combustion and ventilation air and no chemicals,
garbage, gasoline, combustible materials, flammable
vapors and liquids are stored (not even temporarily)
in the vicinity of the boiler.
- Do not allow unsupervised children near the boiler.
Service/inspection of the boiler and the system is
recommended once a year. Maintenance, service and
cleaning are specified in the Installation Instructions.
Before the heating season begins, it is recommended that
the boiler and burner be serviced by a qualified heating
contractor. Service contracts may be established through
gas suppliers or other licensed contractors in your area.
WARNING
As there are no user-serviceable parts on the boiler,
burner or control, the end-user must not perform
service activities or adjustments of any kind on system
components. Failure to heed this warning can cause
property damage, severe personal injury, or loss of life.
CAUTION
Should overheating occur or the gas supply fail to
shut off, do not disconnect the electrical supply to the
pump. Instead, shut off the gas supply at a location
external to the boiler.
WARNING
The operator/ultimate owner is required to have the
heating boiler, burners, and controls checked, as a
minimum once per year, by the original installer or
by a competent heating contractor familiar with the
equipment. Defects must be corrected immediately.
CAUTION
Do not use this boiler if any part has been under water.
Immediately call a qualified heating contractor to
inspect the boiler and to replace any part of the control
system and any gas control which has been under
water.
WARNING
Improper installation, adjustment, service, or
maintenance can cause flue products to flow into
living space. Flue products contain poisonous carbon
monoxide gas which can cause nausea or asphyxiation
resulting in severe personal injury or loss of life.
WARNING
Do Not operate the boiler without the cover in place.

For your Safety (continued)
Safety
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.
Replacement components, spare and wear parts
Components which are not tested with the heating
system may damage the heating system or affect its
functions. Installation or replacement may only be
performed by a qualified heating contractor.
IMPORTANT
Ensure ambient temperatures are higher than 32°F (0°C)
and lower than 95°F (35°C).
Prevent the air from becoming contaminated by
halogenated hydrocarbons (e.g. as contained in
paint solvents or cleaning fluids) and excessive dust
(e.g. through grinding or polishing work).
Combustion air for the heating process, and
ventilation of the boiler room must be free of
corrosive contaminants. To that end, any boiler
must be installed in an area that has no chemical
exposure.
The list below indicates the main, currently known
sources.
Avoid continuously high levels of humidity
(e.g. through frequent drying of laundry).
Never close existing ventilation openings.
Sources of combustion and ventilation air contaminants
Areas likely to contain contaminants:
New building construction
Swimming pools
Remodelling areas, hobby rooms
Garages with workshops
Furniture refinishing areas
Dry cleaning/laundry areas and establishments

Intended Use
General Information
Product Information
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific components
has been carried out.
Commercial or industrial usage for a purpose other than
heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the
manufacturer in each individual case.
Incorrect usage or operation of the boiler (e.g. the boiler
being opened by the system user) is prohibited and results
in an exclusion of liability. Incorrect usage also occurs if
the components in the heating system are modified from
their intended use (e.g. if the flue gas and ventilation air
paths are sealed).
The control unit is a boiler and heating circuit control unit
for the following operating modes:
Weather-compensated operation
Constant (continuous) operation
Your heating contractor will configure the operating mode
during commissioning in accordance with your heating
system. These instructions describe both operating
modes.
Weather-compensated operation
In weather-compensated operation, the supply water
temperature is controlled according to the outside
temperature.
The lower the outside temperature, the higher the supply
temperature. This means that more heat is provided for
central heating on cold days than on warmer days.
Constant operation
In constant operation the boiler provides heating water
with a constant supply temperature regardless of the
outside temperature.
Operation
The control unit is integrated into the boiler and controls
all functions of your system. The control unit is operated
via a 3.5 inch black/white screen.
A wireless (WiFi) module is integrated into the control
unit.
This means the system can also be operated remotely
via the internet using the “ViCare” app.
The boiler is only intended to be installed and operated
in sealed unvented heating systems with due attention
paid to the associated installation, service and operating
instructions. It is only designed for the heating of water
that is of potable water quality.
