IZOKOMPAKT Chimney Installation Schematics

This page shows typical installation schematics for the IZOKOMPAKT modular chimney system. Below you will find detailed descriptions and PDF files for download.

Manual and Diagrams:


Scheme 1. External Installation with Wall Mounting

This is the most common type of installation. The insulated chimney is attached to the external wall of the building using wall brackets.

  • Connection to the Appliance: A 90° Tee-piece is used for the connection. The side outlet of the tee connects to the heating appliance, typically with a single-wall pipe via a special adapter that provides a transition from the insulated (twin-wall) chimney to a single-wall pipe.
  • Inspection and Condensate Drainage: A removable condensate drain (A) is installed at the bottom of the tee-piece. This component also serves as a cleanout door for chimney inspection and cleaning.
  • Wall Penetration: The opening in the wall through which the connecting pipe passes is covered with a decorative plate.
  • Chimney Termination: The chimney is topped with a cone, which protects the insulation layer.
  • Cleaning Options:
    • A: Standard solution – through the removable condensate drain.
    • B: A 90° Tee-piece with a dedicated cleanout door.
    • C: A 90° Tee-piece with an inspection hatch opposite the appliance connection, which simplifies cleaning the horizontal section.

Scheme 2. External Installation Bypassing a Roof Overhang

This schematic is used when it is necessary to bypass a large roof overhang.

  • Fixing and Offset: The chimney is secured to the wall with wall brackets. The offset to bypass the overhang is created using two 45° elbows and a straight pipe section between them.
  • Connection and Inspection: A 90° Tee-piece with an inspection hatch opposite the inlet (A) is used to connect to the boiler. This allows for easy cleaning of both the vertical and horizontal sections. A condensate drain is installed at the bottom. A non-insulated 90° elbow is used for the direct connection to the heating appliance.
  • Structural Stability: If the chimney height above the last fixing point exceeds 1.5 meters, rigid stays must be installed to ensure stability against wind loads.
  • Termination and Decorative Elements: The chimney is terminated with a cone. The opening in the wall is covered with a decorative plate.

Scheme 3. External Installation with a Large Distance from the Wall

A solution for cases where the chimney needs to be positioned at a significant distance from the wall (e.g., to bypass a wide roof overhang without using elbows).

  • Mounting: Extended wall brackets are used, providing a distance of up to 800 mm from the wall.
  • Connection: If the heating appliance is located in a basement, for example, the connection can be made using a 45° Tee-piece in combination with a straight section and a 45° elbow. A condensate drain is installed at the bottom of the tee.
  • Chimney Termination: A cone is installed at the top.
  • Additional Cleaning: For easier maintenance, a 45° Tee-piece with an integrated cleanout door can be used.

Scheme 4. Internal Installation (for Saunas, Fireplaces, Stoves)

A typical solution for saunas, small fireplaces, and cast iron/metal stoves. The chimney runs inside the building through ceilings and the roof.

  • Passing Through Structures: A floor support is used to secure the chimney to intermediate floors, and a rafter support is used for attachment to the rafters.
  • Roof Penetration: A "roof flashing" kit with a storm collar is used for a weather-tight seal where the chimney passes through the roof.
  • Stability: If the chimney extends more than 1.5 m above the roof, rigid stays must be installed.
  • Termination and Protection: The chimney is terminated with a cone. A rain cap can be added for extra protection against precipitation.
  • Decorative Finish: The opening in the ceiling is covered with a two-part decorative plate.
  • Appliance Connection: The section from the heating appliance to the main chimney can be insulated (B), non-insulated (C), or insulated with an offset (A), always observing the required fire-safety clearances.
  • Adjustment and Compatibility: A damper is used to regulate the draft. A reducer is used to match the chimney diameter to the appliance outlet.

Scheme 5. Internal Installation with Wall Mounting

This scheme is similar to Scheme 1, but the chimney is installed inside the building.

  • Installation: The chimney is attached to an internal wall and floor structures and passes through the roof.
  • Connection: An insulated or non-insulated 90° Tee-piece with a condensate drain is installed at the bottom.

Scheme 6. Internal Installation Passing Through a Roof Overhang

Similar to Scheme 2, but the chimney passes directly through the roof overhang.

  • Installation: A roof flashing with a storm collar is used for the penetration. A rafter support is used to fix the pipe to the rafters.
  • Decorative Finish: The opening in the ceiling or soffit is covered with a decorative plate.
  • Cleaning: As in Scheme 1, cleaning can be performed in three different ways.
