Elbow 87° Jeremias fi 80 (model TN0622080) — flue/chimney pipe bend ø80 mm

Jeremias 87° elbow fi 80 (model TN0622080) is a flue/chimney pipe bend with a nominal diameter of 80 mm designed to change the direction of exhaust gases in venting systems. The component provides an 87-degree angle, allowing precise routing of chimney or stove flue runs where a small deviation from a right angle is required. The elbow is intended for installations with gas, oil or solid fuel appliances when materials and temperature limits are compatible with the system.

Advantages

The 87° elbow offers a near-right-angle turn that minimizes flow resistance compared with sharper bends while enabling compact routing in confined spaces. Constructed to match Jeremias system geometry, the component facilitates secure connections to standard ø80 flue sections and helps maintain appropriate draft and exhaust flow. Its design simplifies alignment between appliances and vertical or horizontal ducts, reducing the need for additional adapters.

Suitable for

• Changing direction of flue runs in residential chimneys and stove installations
• Connecting straight ø80 chimney sections around obstacles or offsets
• Gas, oil and solid fuel venting systems where materials and ratings match
• Compact routing in limited space behind appliances or inside flue shafts

Key specifications

• Nominal diameter: 80 mm
• Angle: 87° bend for precise directional change
• Applicable fuel types: gas, oil, solid fuel (when compatible)
• Use: designed for connection within chimney and stove flue systems

How to use

Install the elbow as part of the flue run by inserting and securing it between compatible ø80 straight sections or appliance outlets, following the manufacturer's guidelines for jointing and sealing. Ensure correct orientation of the 87° bend to achieve the desired routing, and verify that all connections are tight and supported to prevent movement. After assembly, inspect the system for clearances, proper slope where required, and compliance with local ventilation and combustion appliance codes.

Usage recommendations

Before installation, confirm material compatibility and temperature ratings with the appliance and the rest of the chimney system. Use appropriate gaskets or sealants if specified by the system manufacturer, and maintain required clearances from combustible materials. Periodic inspection and cleaning are recommended to preserve draft performance and safe operation.
