De Marinis ISO 25 PLUS P2C05 5° twin-wall elbow G50
The De Marinis P2C05 5° elbow is an ISO 25 PLUS G50 component designed to create small offsets and minor alignment corrections in insulated twin-wall flue systems.
Its limited 5° angle allows the flue axis to be adjusted with only a minimal change in direction.
The P2C05 follows the ISO 25 PLUS construction, featuring an AISI 316L BA stainless-steel inner wall, an AISI 304 BA stainless-steel outer wall and 25 mm blown mineral wool insulation.
It is available in nominal internal diameters Ø80, 100, 130, 150, 180, 200, 250, 300 and 350 mm.

What the P2C05 is used for
The P2C05 is used where the flue axis requires a very small directional correction.
Typical uses include:
- compensating minor misalignment;
- avoiding small structural obstacles;
- adapting the flue path to building geometry;
- creating a very limited offset without using a steeper elbow.
P2C05 and other ISO 25 PLUS elbows
- P2C05: 5° elbow;
- P2C15: 15° elbow;
- P2C3: 30° elbow;
- P2C4: 45° elbow;
- P2C9: 90° elbow.
The P2C05 therefore provides the smallest directional change in the range.
ISO 25 PLUS and G50 classification
The P2C05 belongs to the De Marinis ISO 25 PLUS insulated twin-wall flue system.
The high-temperature designation is:
T600-N1-W-V2-L50040/050/060-G50
The G50 classification corresponds to a 50 mm clearance from combustible materials in the certified manufacturer configuration.
Important: G50 applies only to the certified ISO 25 PLUS configuration installed in accordance with De Marinis instructions.
ISO 25 PLUS construction
- Inner wall: AISI 316L BA stainless steel;
- Outer wall: AISI 304 BA stainless steel;
- Insulation: 25 mm blown mineral wool;
- System: insulated twin wall;
- Installation: indoor or outdoor.
CE marking and system designations
The ISO 25 PLUS system is CE marked according to EN 1856-1:2009.
| Designation | Configuration |
|---|
| T200-P1-W-V2-L50040/050-O40 | Wet-operation flue system for positive-pressure applications up to 200 Pa in the applicable configuration. |
| T600-N1-W-V2-L50040/050/060-G50 | High-temperature wet or dry negative-pressure system with G50 combustible clearance. |

Dimensional note: A and B vary according to nominal diameter. External diameter Øe is 50 mm greater than nominal internal diameter Øi. Refer to the De Marinis technical drawing when planning the actual offset.
How to read the technical drawing
- Øi: nominal internal flue diameter;
- Øe: external diameter of the insulated twin-wall system;
- A: main elbow overall dimension;
- B: offset generated by the elbow;
- 5°: deviation angle from the flue axis.
Installation
The P2C05 must be installed according to the correct system orientation and the flue layout specified by the design.
Where several elbows are combined to create an offset, the overall geometry must be checked using the relevant angles, dimensions and any straight sections installed between the elbows.
Connected sections must be adequately supported to prevent excessive mechanical loads from being transferred to the elbow.
Installation must be carried out by qualified personnel in accordance with De Marinis technical documentation, appliance instructions and applicable regulations.
