Safety
Take note of all symbols and notations intended to draw attention to potential hazards or important product information.
These include “DANGER,” “WARNING,” “CAUTION,” and “INFORMATION.” See page 2 for details.
Approvals
Viessmann boilers, burners and controls
are approved for sale in North America by
International Approval Services (IAS). All
electrical wiring is to be done in
accordance with the latest edition of the
National Electrical Code ANSI/NFPA 70.
In Canada use latest edition of CSA
C22.1 Part 1 and/or local codes.
Please carefully read this manual prior
to attempting installation. Any
warranty is null and void if these
instructions are not followed.
We offer frequent installation and
service seminars to familiarize our
partners with our products. Please
inquire.
Working on the equipment
The installation, adjustment, service, and
maintenance of this boiler must be done
by a licensed professional heating
contractor who is qualified and
experienced in the installation, service,
and maintenance of hot water heating
equipment. There are no user-serviceable
parts on this equipment.
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 V power
supply outside of the boiler room. The
installer must provide maximum 15 A
overcurrent protection for the 120 V
power supply (fuse or circuit breaker).
Ensure that all contacts have sufficient
insulation clearance to live parts and
are certified for these applications.
Proper consultation with Viessmann
Manufacturing Company Inc. should
occur when installing components not
included in the Viessmann product
line.
No static discharge to the internal
componentry must ever occur when
working with opened control
equipment.
