DESCRIPTION
The 90° “T” fitting (90.CPM) represents the starting point of the chimney system.
Its main features are:
- body cavity filled with mineral wool to avoid heat loss and ensure good system performance;
- tail ventilation cavity with intake grille and male-female glass that guarantees sealing following coupling with the 80.CPM manifold;
- removable cap through a quick double hook opening/closing system that allows unloading and cleaning of unburned products even 5 cm from the floor.

FEATURES
This fitting is composed of two parts that have complementary and distinct functions:

1. The BODY, characterized by a 25 mm insulated cavity:
- Internal Wall: Stainless Steel 316 BA (EN 1.4404 - L50) thickness 0.5 mm.
- External Wall: Stainless Steel 304 BA (EN 1.4301 - L20) thickness 0.5 mm or Copper thickness 0.6 mm.
- Insulation: Rock wool cups, thickness 25 mm, density 90 kg/m3.
- A lower cap with hook opening/closing, allows cleaning even in stoves with a very low connection.
2. The CODINO, characterized by a ventilation cavity of 25 mm:
- Internal Wall: Stainless Steel 316 BA (EN 1.4404 - L50) thickness 0.5 mm.
- External Wall: Stainless Steel 304 BA (EN 1.4301 - L20) thickness 0.5 mm or Copper thickness 0.6 mm.
- Return grille in the lower part of the external DN

• The BODY, has the function of conveying, into the Chimney System, the exhausts produced by the combustion of pellet or wood appliances; the CODINO, through the ventilation grilles, performs the function of taking in the air necessary for the combustion processes.
• This fitting, combined with the article (80.CPM - Coaxial "M" manifold), forms a KIT which finds application in the management of smoke exhausts and the air intake necessary for the combustion processes of PELLET or WOOD appliances.

APPLICATIONS
Conveyance and disposal of products deriving from combustion processes of PELLET or WOOD stoves, at the service of Chimney Systems in compliance with UNI EN 1856-1.

For the designation of the Chimney System according to the UNI EN 1856-1 Standard, the following is permitted:

Operation:
- dry (D)
- wet (W)

Pressures:
- Positive (P1 = 200 Pa)
- Negative (N1 = 40 Pa).

Operating Temperatures:
- ≤ 200 °C with silicone gasket and P1 = 200 Pa
- ≤ 600 °C without silicone gasket and N1 = 40 Pa

INSTALLATION
• The “COAXIAL KIT 90.EB” belongs to the range expansion of products made by Zinco Group.
• It is used in the processes of expulsion of exhaust fumes and introduction of combustion air in pellet stoves, in particular in those situations in which the connection with the chimney system cannot be positioned in the immediate vicinity of the generator, but must be located high up. As standard, it is made in the following diameter combinations: 80x130 and 100x150, both with a 60 mm single-wall return sleeve. Materials and processes compliant with the Current Regulations are used for its construction.
The KIT is made up of two elements that can be assembled and are complementary:
1. 90° T-fitting with air intake grille
- internal duct: AISI 316 BA thickness mm 0.5 (EN 1.4404 L50050)
- external duct: AISI 304 BA thickness mm 0.5 (EN 1.4404 L20050)
2. linear element with recovery sleeve
- internal channel: AISI 316 BA thickness mm 0.5 (EN 1.4404 L50050)
- external duct: AISI 304 BA thickness mm 0.5 (EN 1.4404 L20050)

• The first component of the kit is a double-wall 90° T-fitting, with a body insulated with mineral wool (thickness 25 mm, density 90 kg/m3) and a tailpiece, with a ventilation cavity 25 mm thick, isolated from the body, which, thanks to a lower multi-perforated grille, allows the entry of the air (combustive) necessary for combustion. The second component, on the other hand, is a double-wall linear element, characterised by an internal channel, which allows the expulsion of the exhaust products generated by the combustion processes and by a ventilation cavity (thickness 25 mm), which allows the passage of the air taken from the grille and conducted, by means of the 60 mm diameter intake sleeve, to the generator for combustion.
