1.1 Safety
This “Attention” symbol is positioned b efore all important safety tips.
Please follow these instructions in detail to avoid property damage, personal injury, or loss of life.
H Installation
Please carefully read this manual prior to
attempting equipment operation. Any
warranty is null and void when these
instructions are not followed.
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 C 22.1
Part 1 and/or local codes.
We offer frequent installation and service
seminars to familiarize our partners with our
products. Please inquire.
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
supply to equipment, heating system, and
all external controls and power supplies
has been deactivated. Close main gas
or oil supply valve. Take precautions in
both instances to avoid accidental
activation of power during service work.

2.2 Method of Operation of the Heating System
Optimum interplay of the individual
components of the heating system is
required in order to generate the right
amount of heat needed to cover the heating
requirements at all times and in all weather
conditions; the boiler and the heat
distribution system (radiators, domestic hot
water tank, pipes etc.) must be correctly
matched to each other. To control this
system, your Viessmann boiler is equipped
with the Dekamatik digital indoor/outdoor
boiler and heating system control.
2.3 Control Activation
On/off switch
I=ON
The Dekamatik matches the boiler water
temperature to various changing conditions
(e.g. the outdoor temperature or a higher
boiler water temperature for heating up a
domestic hot water tank, if installed).
Domestic hot water priority is feasible.
The Dekamatik possesses an integrated
diagnostic system which can recognize and
indicate any malfunctions.
The initial start-up must be conducted by
the heating contractor.

minimum boiler water temperature in order
to avoid damage to the heating system due
