The GEFEST 25P, 30P and 45M, GROM 30P portal extension is a cast iron component designed to extend the portal of compatible GEFEST wood-burning sauna stoves. It is used when the standard portal length is not sufficient due to the thickness of the wall.
The extension length is 150 mm.
The extension is made of cast iron. During installation, the joints must be properly sealed in accordance with the manufacturer’s installation requirements.
If a longer portal is required and several extension elements are to be used, the specific installation conditions must be assessed and fastening elements of the appropriate length must be selected in accordance with the manufacturer’s instructions.
