MONOInox – AISI 316L Stainless Steel Single-Wall Chimney System

The MONOInox range is a modular AISI 316L BA stainless steel single-wall chimney system designed for flue liners, connecting flue pipes and combustion-product evacuation systems.

The range is available in numerous diameters and includes straight pipes, elbows, T-connectors, terminals, support plates, collars and accessories for configuring a complete flue system according to the installation requirements.

The components use a socket connection system that allows them to rotate relative to each other through up to 360°, making alignment easier during installation.

MONOInox technical specifications

When should a single-wall chimney system be used?

An AISI 316L stainless steel single-wall system is particularly suitable for:

• relining and renovating existing chimney flues;
• installation inside chimney shafts and technical ducts;
• connecting flue pipes between an appliance and chimney where compatible with the required system configuration;
• air intake or exhaust applications using dedicated components from the range.

Where the chimney is installed outdoors or where greater thermal insulation is required, an insulated twin-wall chimney system may be more appropriate.

AISI 316L BA stainless steel

MONOInox is manufactured from AISI 316L BA stainless steel, widely used in chimney applications due to its resistance to corrosion and acidic condensates generated by combustion gases.

The system is declared with V2 corrosion resistance, suitable for the fuel types covered by its product designation.

Use with or without gasket

The performance classification of MONOInox depends on whether a sealing gasket is installed.

With gasket, the system is designated T200 – P1 – W, for temperature class T200, positive-pressure operation and wet conditions.

Without gasket, the stated configuration is T600 – N1 – D, for dry negative-pressure operation with temperature class up to T600.

The correct configuration must be selected according to the connected appliance, fuel, flue-gas temperature, operating pressure and possible presence of condensate.

360° socket connection

MONOInox components are joined using a socket connection. The elements can be rotated relative to each other through up to 360°, helping align elbows, branches and fittings during installation.

Available components

The MONOInox range includes numerous components for building a complete chimney system:

• straight pipes in different lengths;
• elbows in different angles;
• T-connectors and reduced T-connectors;
• telescopic elements;
• caps and condensate drains;
• support plates and brackets;
• centering collars for relining;
• weatherproof and anti-wind terminals;
• air intake and exhaust grilles;
• other fittings and installation accessories.

Available diameters

The MONOInox range covers a wide range of diameters. Some straight elements are available from Ø60 mm up to Ø500 mm, while specific accessories may have different size ranges.

Always check the available sizes on the individual product page.

How to choose MONOInox components

Before configuring the system, check:

• the diameter required by the appliance and flue design;
• the fuel used;
• flue-gas temperature;
• positive- or negative-pressure operation;
• whether condensate may be present;
• the overall system height;
• the number of elbows and branches;
• the support, inspection and condensate-drain components required.

The chimney system must be correctly sized and configured according to the connected appliance and installation conditions.
