System Design Considerations/Burner Alternatives

VITOROND 200, VD2

System Design Considerations

(continued)

/Burner Alternatives

Water quality

Treatment for boiler feed water should be
considered in areas of known problems,

such as where a high mineral content and
hardness exist. In areas where freezing

might occur, an antifreeze may be added to
the system water to protect the system.

Please adhere to the specifications given by
the antifreeze manufacturer. Do not use

automotive silicate-based antifreeze. Please
observe that an antifreeze/water mixture

may require a backflow preventer within the
automatic water feed and influence
components such as diaphragm expansion

tanks, radiation, etc. A 40% antifreeze
content will provide freeze-up protection to

-10°F / -23°C. Do

not

use antifreeze other

than specifically made for hot water heating

systems. System also may contain
components which might be negatively

affected by antifreeze. Check total system
frequently when filled with antifreeze.

Follow the instructions of antifreeze
manufacturer.

Oxygen diffusion barrier

underfloor tubing

The boiler warranty does not cover leaks
resulting from corrosion caused by the use
of underfloor plastic tubing without an

oxygen diffusion barrier. Such systems must
have the tubing without oxygen diffusion

barrier separated from the boiler with a heat
exchanger. Viessmann recommends the use

of underfloor plastic tubing with an oxygen
diffusion barrier.

Burner manufacturer

Weishaupt or Riello

Burner/Gas train approval

Standard approvals are CSA (for Canada)
and UL (for U.S.). IRI and FM approved
equipment is also available - please inquire.

Electrical requirements

Weishaupt W Series burners are available in
120 VAC, single-phase, in a 60 Hz
configuration. L, G, and GL Series burners

listed below are available in 120 VAC single
phase, 208 VAC three-phase, 460 VAC

three-phase, or 575 VAC three-phase, all in
60 Hz configuration. It is generally

acceptable to use voltages within ten
percent of the supply voltage. Available

voltage inside boiler room must be provided
at time of order. Ensure appropriate

disconnect means and overcurrent
protection.

Natural gas pressure

Natural gas pressures and heating values as
provided by the gas utilities vary greatly
across North America. Select the
appropriate gas train accordingly. Low
pressure gas trains have a maximum input

of 14 ”w.c.; high pressure gas trains have a
maximum pressure of 5 psig. Minimum gas
pressures apply - please inquire. Gas
pressures and heating values at site must be
provided at time of order.

Factory prewired components

Custom factory prewiring by Viessmann
ensures optimal functionality, compliance
with regional requirements, and ease of
installation in the field. Pricing provided by

Viessmann includes all necessary hardware
items such as junction panel, burner power
supply, boiler door safety switch (where
necessary), and all essential pressure
switches, as well as interconnection with
conduit between control and burner.

Electrical drawings provided upon product
delivery.

Boiler/Burner start-up

Vitorond 200, VD2 boilers with Weishaupt
burners require start-up by Viessmann.
Please inquire to obtain details regarding the
necessary prerequisites of boiler/burner
start-up procedures.

To minimize delivery lead times, please
ensure that critical technical information is
provided at time of order. Viessmann will
not process an order without site-specific
information regarding available voltage and
gas pressure. In addition Viessmann
recommends that gas pressure information
be provided in writing by the local gas
utility.
