Throttle valve FAL with axle for subsequent installation in various sizes

FAL throttle valves are used to regulate the chimney draught. If there is no throttle valve installed in the stove pipe itself, this throttle valve with a continuous axis can be used for subsequent installation.

The throttle valve is a metal plate made of FAL (hot-dip aluminized steel sheet) that can be installed in the stove pipe. This has a continuous axis. This handle is located outside the stove pipe after installation. This allows the throttle valve to be opened and closed.

The chimney draught should only be regulated if regulation via the primary and secondary air dampers does not bring any improvement.

A high draft does help the fire to start well, but the heat generated is also dissipated quickly. The correct setting of the throttle valve reduces this enormously.

If the stove or fireplace is not used for a long time, the throttle valve should also be closed. However, the next time you light the stove, make sure that it is opened again. If this is not the case, you will be faced with a large cloud of smoke at the installation site. The exhaust gases cannot escape and the chimney draft is too low.
