ATAG Commercial launches new Flue Gas System Guide

ATAG Commercial has introduced a new ‘Flue Gas System Guide’, containing all the essential information about the extensive flue options available for the company’s range of boilers.
The new literature contains all the relevant technical information, product codes and installation advice heating engineers require.
There are also dedicated sections on the flue systems available, including cascade kits, as well as components, dimensions and essential design and sizing information for all ATAG Commercial boilers. With the company offering open, room sealed, concentric and communal flue systems, there are options available for a wide range of domestic and commercial applications.

The document offers guidance on the requirements and regulations for the construction of flue systems, as well as which items are suitable for use with each of ATAG Commercial’s A Series, Q Series and XL Series boilers. Maximum flue lengths are comprehensively detailed, alongside information about safe termination and the suitable positions from which to achieve this.
All available components are referenced, providing installers with information on everything from wall terminals and concentric pipes, through to air filters and plume kits. ATAG Commercial also offer a range of flexible flue options for applications where a system needs to be routed through an existing chimney or void, such as in listed buildings where structural changes are forbidden.
Commenting on the new brochure, Paul Martin, National Sales Manager at ATAG Commercial, said: “Selecting the right flue is equally as important as the boiler, as they are essential for a heating system’s safe operation. At ATAG Commercial, we have a comprehensive range of accessories for all our boilers, which ensure they remain reliable and efficient throughout their operating life. Our new literature provides installers with all the information they need to find the correct flue for any application, whatever the size.”
