Vitoligno 300-C Installation/Service

Product Information

Viessmann solid-fuel boiler may only be installed and
serviced by trained personnel.
Wood pellet fired hot water boiler for operation primarily
with modulating boiler water temperatures in closed loop
forced circulation hot water heating systems.
The Vitoligno 300-C is a fully automatic wood pellet
boiler. The boiler has an efficiency of up to 85% when
converting pellets into heat.
The wood pellet boiler offers a wide spectrum of
applications – from low energy houses to buildings
with a higher heat demand.
Modulation of 1:3 leads to low consumption and clean
combustion under partial load conditions. A ceramic
ignition unit consumes little power, whilst innovative
combustion technology featuring dual combustion
control with lambda probe and flue gas temperature
sensor keeps dust values low.
The Vitoligno 300-C offers versatile and flexible fuel
supply system options for almost any application.
Pellets are supplied to the boiler either via a flexible
screw conveyor or a vacuum system. Thanks to its
compact design, it is suitable for installation in rooms
with low ceiling heights. Versions with pellet supply
via a vacuum system are supplied with a pellet hopper
with integral suction turbine and capacity for one-day
operation. The wood pellet boiler is convenient to use
and is partially automated. The automated features
include ignition, heat exchanger cleaning, the self-
cleaning rotary finned grate and fully automatic removal
of ash. The mobile ash box only needs emptying once
or twice a year. Due to the sealed ash box, ash removal
is also clean and stress-free.
Operating the boiler is easy with the weather-
compensated digital Ecotronic control unit. The integral
Ecotronic controls up to four heating circuits with
mixing valve. The Ecotronic controls boilers with pellet
supply, heating circuits and the tank temperature.
The clear display, with graphic capability and multiple
line plain text user prompts, provides intuitive operation
and easy adjustment of all relevant parameters.
In combination with a solar thermal system, current
solar data is also shown on the display.
The Vitotrol 350-C (accessory) control unit extension
enables the wood pellet boiler to be operated from
the living space as well. With the 5" (125 mm) color
touchscreen display in 16:9 format, operation couldn't
be easier. The Vitotrol 350-C enables remote control
of the boiler with all relevant adjustment options and
display of all relevant information about the boiler and
the heating water buffer tank. Optionally, the Vitotrol
350-C can be used not only as a remote controller but
also as a cascade controller. Up to four boilers can
be connected in a cascade. Additionally, one oil/gas
boiler can be enabled via the master boiler. The most
important control circuits of the cascade system can
be displayed and operated.
The heat-up condition of the buffer tank is displayed.
Maximum allowable working pressure (water)............45 psi
Maximum water temperature...................230°F (110°C)
Maximum boiler temperature.....................203°F (95°C)
This boiler does not require a flow switch.
WARNING
Exposing the boiler to pressures and temperatures in
excess of those listed will result in damages and will
render the warranty null and void.
