- the space between the block and the flue pipe itself can be used for independent air supply to the appliance
- advantageous price
- simple and quick assembly

Description

## Characteristics and advantages

 

 

It is used for exhausting flue gases from gas and condensing boilers with a maximum flue gas temperature at the appliance throat of 120°C. It is designed for negative pressure as well as positive pressure flue gas paths. It is suitable as a common chimney for multiple connections of gas appliances on several floors. It works as a concentric flue system for type C appliances.

The advantage is that the outer concrete or brick block can be declared EI fire resistant, so there is no need to deal with additional cladding as with systems that do not have a silicate outer cladding system.
