The De Marinis P2AP is a Chinese-style weather, anti-wind and anti-downdraught terminal for the ISO 25 PLUS G50 insulated twin-wall flue system.
It is installed at the top of the chimney and features a large upper cover designed to protect the outlet from direct precipitation while providing increased shielding against wind.
Its configuration makes it particularly suitable for exposed installations subject to strong wind, rain or snow, while maintaining the openings required for combustion-product discharge.
The P2AP is available in versions P2AP80, P2AP100, P2AP130, P2AP150, P2AP180, P2AP200, P2AP250 and P2AP300.
The P2AP completes the upper section of the chimney and protects the flue outlet against weather exposure.
Its geometry helps to:
The P2AP features a large upper weather cover above the flue-gas discharge area.
The cover has a greater diameter than the central body, providing protection against direct precipitation and increased shielding from wind action.
Technical note: an anti-wind or anti-downdraught terminal can help reduce the influence of adverse weather conditions but does not replace correct chimney sizing. Draught, chimney height, pressure losses and outlet position must be assessed as part of the complete flue design.
De Marinis also offers a terminal with a similar function within the ISO 25 range, identified as I2AP.
P2AP and I2AP perform the same general role within their respective product ranges: both are intended to provide weather, anti-wind and anti-downdraught protection at the chimney outlet.
The correct component must be selected according to the De Marinis flue system installed.
The P2AP 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 De Marinis system configuration.
Important: G50 applies exclusively to the certified ISO 25 PLUS configuration installed according to De Marinis instructions.

Dimensional note: De Marinis specifically lists Øn, H, Ød and Øc for the P2AP. The values above reproduce the manufacturer's dimensional nomenclature and should be read together with the corresponding technical drawing.
The P2AP must be installed as the upper chimney terminal according to the correct assembly direction and De Marinis instructions.
The outlet position must provide proper discharge of combustion products and comply with applicable installation requirements, building configuration and appliance instructions.
The terminal should remain accessible for periodic inspection and maintenance.
Installation must be carried out by qualified personnel in accordance with De Marinis technical documentation and applicable regulations.
