SYSTEM APPLICATIONS
Oblong Shaped FluesOBLONG SHAPED FLUES

The Ahrens System is not limited to round flues only. Rectangular chimneys sometimes require an oblong-shaped flue. Your Ahrens dealer has access to hundreds of oblong shapes to assure proper sizing for your appliance or fireplace.

Offset ChimneyOFFSET CHIMNEY

Offsets in chimneys are a common occurrence. By controlling the cable, the bell is guided through the turn. Proper placement of the guide pin will assure proper wall thickness of lining material.
Chimney PartitioningCHIMNEY PARTITIONING

Many chimneys are drastically oversized inside. Ahrens versatility enables the installer to partition the chimney and line one side, reducing material quantities, in turn reducing your cost. If the partitioned area is large enough, another flue can be installed at a later date if ever needed.
Multiple FluesMULTIPLE FLUES

With or without a brick partition wythe wall, multiple flue chimneys are no challenge. Providing there is adequate room in the chimney, there is no limit to the number of flues that can be installed simultaneously.
Smoke Chamber LiningSMOKE CHAMBER LINING

Many lining/relining systems today are limited to the installation in the chimney only. Due to Ahrens' versatility it's possible to line even the smoke chamber area that channels the smoke to the flue. It's becoming more and more important to address this area if deteriorated. The Ahrens System will add structural strength, insulate and form a smooth surface to channel the smoke to the flue.
Zero ClearanceZERO-CLEARANCE

Current building codes require combustible building material to be two inches from the chimney. Unfortunately many older structures have these materials actually touching the chimney with no clearance for heat to escape. The Ahrens System has been tested and listed for installation in chimneys with zero-clearance to combustibles to make your chimney safer.
