Product Specifications

Installation and Usage Guide

The Z103 chimney damper is installed directly into the chimney channel during stove or fireplace construction.
The installation opening must match the specified size to ensure correct fit and sealing.

After fuel combustion is completed, the damper should be closed to reduce heat loss through the chimney.
In systems with multiple flue paths, the damper can also be used to redirect smoke and exhaust gases as required.

Installation should be carried out by qualified professionals familiar with local building codes and heating system standards.
