25 cm De Marinis DESIGN SDPF element with flue gas test probe port
The 250 mm De Marinis DESIGN SDPF straight element is a component of the DESIGN flue system featuring an integrated port for inserting a flue gas test and analysis probe.
It is designed for wood-burning stoves, fireplaces and biomass appliances and provides a dedicated point for combustion and flue gas checks.
The component is manufactured from 2 mm carbon steel with a matt black high-temperature finish. Its robust construction and clean appearance make the DESIGN range particularly suitable for visible indoor installations.
It is available in nominal diameters Ø 120, 130, 140, 150, 160, 180 and 200 mm.

What the DESIGN SDPF element is used for
The SDPF combines the function of a 25 cm straight flue element with a dedicated flue gas test probe port.
The integrated provision allows a technician to carry out combustion and flue gas checks through a dedicated sampling point in the connecting flue.
It is particularly useful where an accessible flue gas sampling point is required for technical inspections and combustion checks.
Before purchasing, select the correct diameter and check that it matches the appliance flue outlet and all other components used in the installation.
Flue gas test probe port
The integrated test point allows suitable measuring equipment to be inserted for flue gas sampling and combustion analysis.
The position of the component within the flue connection must be selected according to the appliance characteristics, measurement requirements and applicable technical regulations.
The presence of the test port facilitates inspection procedures but does not replace the technical assessment required to determine the correct sampling position.

Comparing the technical drawing, dimensional table and selected diameter helps identify the exact De Marinis product code required for the installation.
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
Pipe diameter, probe port position, flue route, safety clearances and installation method must be determined according to the appliance, flue system and applicable regulations.
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.
