General Information
Approvals
Viessmann boilers, burners and
controls are approved for sale in North
America by CSA International.
Codes
The installation of this unit shall be in
accordance with local codes. In the
absence of local codes, use:
CSA C22.1 Part 1 and/or local codes
in Canada
National Electrical Code ANSI/NFPA
70 in the U.S.
Always use latest editions of codes.
Working on the equipment
The installation, adjustment, service,
and maintenance of this product must
be done by a licensed professionalheating contractor who is qualified and
experienced in the installation, service,
and maintenance of hot water boilers.
There are no user serviceable parts on
the boiler, burner, or control.
Please carefully read this manual prior
to attempting installation. Any
warranty is null and void if these
instructions are not followed.
For information regarding other
Viessmann System Technology
componentry, please reference
documentation of the respective
product.
We offer frequent installation and
service seminars to familiarize our

inquire.
The completeness and functionality of
field supplied electrical controls and
components must be verified by the
heating contractor. These include low
water cut-offs, flow switches (if used),
staging controls, pumps, motorized
valves, air vents, thermostats, etc.
Ensure main power supply to
equipment, the heating system, and all
external controls has been deactivated.
Close main oil or gas supply valve.
Take precautions in both instances to
avoid accidental activation of power
during service work.

Important Regulatory and Installation Requirements
Power supply
Install power supply in accordance with
the regulations of the authorities
having jurisdiction or, in the absence of
such requirements, in accordance with
National Codes. Viessmann
recommends the installation of a
disconnect switch to the 120 VAC
power supply outside of the boiler
room. The installer must provide
maximum 15 A overcurrent protection
for the 120 VAC power supply (fuse or
circuit breaker).
Working with an open control
No static discharge to the internal
componentry must ever occur when
working with opened control
equipment.

IMPORTANT
This installation example depicts a
possible piping layout for multiple
Vitodens 200-W, WB2B boilers
equipped with Viessmann system
Technology. Please note that this
example is based on a simplified
conceptual drawing only! Piping and
necessary componentry must be field
verified.
A low water cut-off (LWCO) must be
installed where required by local codes.
Proper installation and functionality in
the field is the responsibility of the
heating contractor.
WARNING
When extending wire, there is the
possibility of exposure to
electromagnetic interference.
Avoid running wires beside or near
high voltage 120/240 VAC
conductors. If proximity to high
voltage conductors cannot be
avoided, use stranded, twisted pair
or shield design wire. Ensure that
only one end of the shielding is
grounded.

Outdoor temperature sensor
Installation – Vitotronic 300-K
The outdoor temperature sensor should be mounted 6.5 to 8ft / 2 to 2.5m above
ground level on the north or north-west facing wall of the building. In the case of
multi-storey buildings, it should be mounted in the upper half of the second storey.
Make sure that the sensor is not located over windows, doors and air vents, nor
immediately beneath a balcony or guttering.
Do not paint over the outdoor temperature sensor housing.
1. Remove the cap.
2. Mount the bottom part of the sensor
housing.

Note:
When installing the sensor in DHW
tanks of other makes, make sure
that the sensor is pressed against
the sensor well of the DHW tank by
means of a suitable device.
2. Ensure that the maximum
permissible domestic hot water
temperature is not exceeded. If
necessary, install a suitable safety
device for this purpose.
Check the sensor
