S 1

With a rated input of 300 to 380 MBH/

88 to 111 kW, the Vitogas 100 makes a

grand entry into the heating technology

industry.

The new Vitotronic control generation,

minimum noise levels and economical

operation, make the Vitogas 100, GS10 the

choice for single- as well as multiple-boiler

applications.

he benefits at a glance:

HHigh operational reliability and a long

service life due to special high-grade gray

cast iron with lamellar graphite and a low

thermal load on the heat e changer

surface.

HClean combustion due to atmospheric

premi burner with super-stoichiometric

premi ing: NO < 27.9 ppm (air-free),

CO < 9.2 ppm (air-free). The Vitogas 100

therefore satisfies the requirements of the

German environmental emblem “Blue

Angel”, Swiss Clean Air Regulations and

California Regulations.

HEconomical and environmentally friendly

operation via modulating boiler water

temperatures.

Combustion efficiency of up to 85.6%.

HEven during partial-load operation, the entire

combustion chamber is used allowing for

balanced usage of burner and boiler.

HIntermittent pilot ignition system provides

soft, quiet and extremely reliable ignition.

Heat exchanger surfaces of special

high-grade gray cast iron for high

operational reliability and a long

service life

Installation Examples

hese examples depict possible piping

layouts for Viessmann product equipped

with Viessmann System echnology. For

boiler and tank combinations, please install

only the feasible combinations listed in the

Price List.

hese are simplified conceptual drawings

only!

Piping and necessary componentry must be

field verified.

Proper installation and functionality in the

field is the responsibility of the heating

contractor.

Single-stage operation can only occur when

the boiler water temperature is above the

minimum temperature and a demand for

heat is present. When the water

temperature is above the minimum, the

boiler control will determine full input

operation or partial load operation based on

the demand for heat. Refer to boiler control

instructions.

Install LWCO where required by local codes.

IMPOR AN

Vitotronic boiler controls are factory

set for single-stage operation. he

Vitogas 100, GS10 boiler control must

be programmed on-site for two-stage

operation.

Without mixing valve

e.g. with Vitotronic 100

The installation of a flow check valve in the

heating supply pipe prevents uncontrolled

heat flow to the heating system by gravity

during priority switching of domestic hot

water heating or during summer operation.
