Outside Firing Extension

An extension collar for firing the stove from outside the sauna room – available on all wood burning models.

We prefer that you choose an extension that is 2″ larger than the concrete wall you will use. For example, if you are using 8″ block, we recommend the 10″ extension.

This will give a 2″ setback from your heater to the concrete wall in the sauna room, while the door will be flush to the outer wall.

We also offer the outside Firing Extension with a Decorative Glass Window

The glass window measures 5 1/2″ x 8 1/2″, includes interior glass protector, and can be decorated with the birch leafs shown, or plain (no trim).
