0-90° De Marinis DESIGN SDC9IG swivel elbow with inspection access
The De Marinis DESIGN SDC9IG swivel elbow is an adjustable component of the DESIGN flue system designed to create changes of direction from 0° to 90° in the flue connection of wood-burning stoves, fireplaces and biomass appliances.
Its adjustable design allows the connecting flue to be adapted to the installation layout, including intermediate angles that cannot be obtained with conventional fixed-angle elbows.
The SDC9IG also features an inspection opening, providing easier access to the inside of the fitting for periodic inspection and cleaning.
It is manufactured from 2 mm carbon steel with a matt black high-temperature finish and is available in nominal diameters Ø 120, 130, 140, 150, 160, 180 and 200 mm.

What the DESIGN SDC9IG elbow is used for
The SDC9IG is used where the direction or offset of the connecting flue must be adjusted using an angle between 0° and 90°.
Compared with a fixed elbow, its swivel configuration provides greater installation flexibility and helps adapt the flue route to the actual position of the appliance outlet and chimney connection.
It can therefore be configured for both large changes of direction and intermediate angles, depending on the geometry required by the installation.
Before purchasing, select the correct diameter and check that it matches the appliance flue outlet and the other DESIGN components used in the installation.
0-90° adjustable configuration
The main feature of the SDC9IG is its ability to adjust the angle of the fitting, allowing the flue route to be adapted to the dimensional requirements of the installation.
The adjustment must provide a stable configuration compatible with the correct operation of the flue system.
The number of elbows, selected angles, section lengths and overall flue route should be assessed according to the appliance characteristics and available chimney draught.
Inspection and cleaning access
The SDC9IG incorporates a dedicated inspection access, providing easier access to the inside of the fitting during maintenance.
Soot and combustion residues can accumulate around changes of direction, so an accessible inspection point facilitates periodic checking and cleaning of the connecting flue.
Important: the inspection opening must be correctly closed before operating the appliance. Inspection, cleaning and maintenance must be carried out according to the manufacturer's instructions and applicable requirements.

Technical note: dimensions A and B vary according to the nominal diameter, while insertion dimension I is 50 mm for all SDC9IG variants. The elbow is adjustable from 0° to 90° and features an inspection opening. Always refer to the technical drawing included on the product page.
How to read the technical drawing
- Øn: nominal elbow diameter
- A: dimension varying according to nominal diameter
- B: overall dimension shown in the technical drawing
- I: insertion dimension, 50 mm
- Adjustment: configurable angle from 0° to 90°
- Inspection: access for internal inspection and cleaning
Comparing the technical drawing, dimensional table and selected diameter helps verify the installation dimensions and identify the exact De Marinis product code.
DESIGN system compatibility
For correct dimensional continuity and system configuration, the use of De Marinis components from the same range and with the same nominal diameter is recommended.
Before combining components from different systems or manufacturers, their dimensional, technical and regulatory compatibility must be checked.
Installation
Diameter, selected elbow angle, accessibility of the inspection opening, total number of changes of direction, flue connection length and draught must be assessed according to the appliance and flue system.
The DESIGN system is intended for indoor installation. Installation must be carried out by qualified personnel in accordance with the appliance manufacturer's instructions and applicable technical requirements.
