Extension of the portal of the Gefest Groza 18/24 (M) 120 mm

To remove the portal for thicker walls, it is possible to install additional portal extensions 100 and 150 mm long.

Theoretically, an unlimited number of additional extensions can be installed, you just need to replace the M8 studs for the portal screed to the appropriate length (for example, if we add 2 extensions of 100 mm each, the stud increases by 200 mm).

It is necessary to take into account the convenience of use - the loading of firewood will need to be done through an enlarged tunnel, the ash box will also be deepened inside. When installing additional extension cords, their joints must also be coated with sealant during assembly.
