Internal Twin Wall Assembly Guide

 

Basic Internal Installation
The chimney should be appropriately supported at 4m intervals, with lateral support every 1.5m. Refer to the manufacturer's instructions for more details.
Joints within walls, ceilings, or floors should NOT be made.
Where there is a risk of combustible materials coming into contact with the system, the minimum distance from combustible materials (60mm) must be maintained throughout by a permanent enclosure or shield.
When the system goes through a wall, a sleeve should be used and weather-proofed as required.
Components should not be modified.
A chimney notice plate, carbon monoxide detector, and air vent should be installed in the same room as the appliance.
