De Marinis DESIGN SDSM adjustable support bracket

The De Marinis DESIGN SDSM adjustable support bracket is an accessory designed to support and secure flue pipes used with wood-burning stoves, fireplaces and biomass appliances.

The main feature of the SDSM is its adjustable fixing system, which allows the distance between the flue pipe and the supporting wall or structure to be progressively adapted.

This makes the bracket particularly useful where the pipe cannot be installed directly against the supporting surface or where a controlled offset is required.

Its matt black finish matches the other components of the De Marinis DESIGN range, making it suitable for visible indoor installations.

The SDSM bracket is available in nominal diameters Ø 120, 130, 140, 150, 160, 180 and 200 mm.

What the DESIGN SDSM support bracket is used for

The SDSM is used to support the flue pipe and maintain its required position relative to the wall or supporting structure.

Compared with a conventional wall clamp, its adjustable configuration provides greater installation flexibility where the pipe must be kept at a specific distance from the supporting surface.

It can be used on vertical sections or other configurations requiring an additional mechanical support point.

Before ordering, select the diameter matching the flue pipe to be supported.

Adjustable distance from the supporting structure

The SDSM fixing can be adjusted to adapt the pipe position to the installation requirements.

The standard configuration allows adjustment between a minimum length of 105 mm and a maximum length of 230 mm.

De Marinis technical data also specifies a minimum length with cutting of 30 mm, allowing a shorter configuration where permitted by the installation design.

Important: any adjustment or shortening of the bracket must comply with the manufacturer's intended configuration and must not compromise the mechanical stability of the system. The supporting structure must be suitable for the applied loads.

Flue system support and stability

The SDSM performs a mechanical support function and does not alter the internal route of combustion products.

The number, position and spacing of support brackets should be determined according to the system layout, component weight and characteristics of the supporting structure.

The fixing must provide stability without deforming the flue pipe or interfering with the joints between system components.

De Marinis dimensions and product codes

The table below lists the available SDSM adjustable support bracket variants. All dimensions are expressed in millimetres.

Øn indicates the nominal diameter of the compatible pipe, while H, L1, L2, Lmin and Lmax correspond to the dimensions shown in the technical drawing included on the product page.

Technical note: all SDSM variants have H = 30 mm, L1 = 150 mm, L2 = 105 mm, minimum length with L2 = 105 mm, maximum length = 230 mm and minimum length with cutting = 30 mm. Always refer to the technical drawing included on the product page.

How to read the technical drawing

• Øn: nominal diameter of the compatible flue pipe
• H: bracket height, 30 mm
• L1: adjustable component dimension, 150 mm
• L2: second component dimension, 105 mm
• Lmin with L2: minimum configured distance with L2, 105 mm
• Lmax: maximum configured distance, 230 mm
• Lmin with cutting: minimum distance according to the specified shortened configuration, 30 mm

Comparing the technical drawing, dimensional table and selected diameter helps verify both pipe compatibility and the adjustment range required for the installation.

DESIGN system compatibility

The SDSM bracket is designed for use with De Marinis DESIGN flue pipes and components.

Select the variant with the same nominal diameter as the pipe being supported.

Before using the bracket with components from other systems, dimensional and mechanical compatibility must be checked.

Installation

Bracket position, adjustment, fixing method and number of supports must be determined according to the flue system layout, component weight and characteristics of the supporting structure.

The bracket must be installed without deforming the flue pipe or interfering with the joints between adjacent components.

Installation should be carried out by qualified personnel, using fixing systems suitable for the supporting structure and in accordance with De Marinis requirements and applicable regulations.
