Oval Chimney Elbow 90° on the Narrow Side RENOFAST

Description and Purpose

The Oval Elbow 90° is a chimney fitting designed to change the channel direction at a right angle. It is necessary for bypassing structural obstacles (beams, wall projections) or shifting the chimney axis.

Geometry Features:

This model is designed with a bend on the narrow side of the oval (115 mm). This means that if you look at the elbow from the side, you will see its wide profile, and the turn is made "on the edge". Please ensure before ordering that you need a turn in this specific plane.

Advantages and Characteristics

• Aerodynamics: The radius of the segmented elbow is calculated to minimize resistance to the flue gas flow, maintaining stable draft even with a sharp turn.
• Seam Reliability: The elbow is manufactured using TIG welding in an inert gas environment. The weld seams are airtight and resistant to intergranular corrosion.
• Material: Acid-resistant stainless steel AISI 304L / 316L is used, capable of withstanding high thermal loads and condensate exposure.
• Easy Assembly: The element features a socket connection ("male-female"), allowing easy docking with straight pipe sections without additional tools.

Technical Specifications

Installation Recommendations

• Support: The turning section experiences increased loads. It is recommended to fix the chimney with wall brackets before and after the elbow.
• Compatibility: The elbow fits perfectly with RENOFAST oval pipes of the corresponding cross-section.
• Inspection: According to standards, after a chimney turn (especially at 90°), it is advisable to provide access for cleaning the horizontal section.
