How the Vitodens 100-W boiler operates...

The Vitodens 100-W boiler uses a premix combustion 

system, which is designed to deliver a certain air-gas 

mixture to the burner for complete combustion. The gas 

is injected upstream of the blower. The burner and heat 

exchanger are part of a forced-draft design. The benefits 

of forced-draft systems are lower component 

temperatures, direct air-fuel connection (premix) for 

improved mixing, and longer service life of the boiler due 

to mild to moderate ambient conditions.
The MatriX cylinder burner, blower and the combination 

gas valve are factory calibrated and pre-adjusted. 

A pneumatic link between combustion air and gas flows 

guarantees optimal boiler performance at all firing rates. 

Blower speed is automatically increased or decreased 

based on heat demand, thereby regulating the amount 

of combustion air drawn. The pneumatic link between air 

and gas introduces the required amount of gas for optimal 

combustion to meet the current heat demand, based on 

a linear relationship between 

 P air and 

 P gas.

Installation Examples

The examples on the following pages depict possible 

piping layouts of the Vitodens 100-W boiler.

Please note that the following examples are simplified 

conceptual drawings only!
Piping and necessary componentry must be field 

verified. A low water cut-off (LWCO) must be installed 

where required by local codes. Proper installation and 

functionality in the field is the responsibility of the heating 

contractor.
