Chimney Renovation Extension Kit Jeremias 60 mm–80 mm (adapter set)

Renovation extension kit Jeremias 60 mm–80 mm (adapter set) provides components for adapting an existing chimney or flue liner from an internal diameter of 60 mm to 80 mm. Designed for renovation and repair work, the kit includes the necessary adapters to connect pipes of different diameters, allowing continuation of an existing flue system with minimal modification. The set is intended for use where safe and reliable enlargement of the flue passage is required during refurbishment.

Advantages

The adapter set is manufactured to fit standard round metal flue liners and supports a secure mechanical connection between 60 mm and 80 mm sections. Its design simplifies installation by eliminating the need to fully replace long stretches of lining, reducing labour and material waste. Components are compatible with Jeremias systems and are produced to maintain proper gas and smoke evacuation when installed according to manufacturer guidelines. The kit helps ensure a continuous, sealed path for combustion gases when integrated correctly into an existing chimney system.

Suitable for

• Chimney renovation projects that require increasing liner diameter from 60 mm to 80 mm
• Repairing or adapting appliance flue connections during building refurbishment
• Connecting mismatched sections of round metal flue liners in residential and small commercial installations

Key specifications

• Purpose: adapter set for diameter transition from 60 mm to 80 mm
• Compatible with round metal flue liners and chimney systems designed for concentric or single-wall connections
• Material: metal components suitable for flue applications (corrosion-resistant finish as specified by manufacturer)
• Connection type: mechanical adapter joints for secure fit between differing diameters
• Application environment: chimney and flue renovation, indoor and enclosed chimney ducts depending on system design

How to use

Prior to installation, verify that the existing chimney or liner sections are structurally sound and that the increased diameter is appropriate for the connected appliance and overall flue system. Install the 60 mm end of the adapter into the smaller liner and the 80 mm end into the larger liner, ensuring each joint is fully seated and secured according to the Jeremias installation instructions. Maintain proper alignment and slope where required by local codes, and ensure seals or gaskets are fitted if included or specified. After assembly, perform a visual inspection of connections and, where applicable, a smoke or pressure check to confirm there are no leaks and that draft is adequate.

Usage recommendations

Use this adapter kit only as part of a compatible Jeremias flue system or equivalent components rated for the same operating temperatures and gases. Confirm appliance compatibility with an increase in flue diameter and follow local building regulations and manufacturer installation instructions. If uncertain, consult a qualified chimney or HVAC professional to evaluate draft characteristics and to complete installation safely.
