Portal extension GFS ZK 25M / ZK 30M / Vanguard 150 mm

    The portal extension is used as an additional element when installing a wall-mounted oven. It must be installed in 99% of cases if the stove is heated from an adjacent room with a steam room.

    Portal extensions are available in lengths of 100 and 150 mm. Theoretically, the furnace portal can be extended indefinitely, respectively, replacing the tightening studs with studs of the required length. Compiled portal extensions must be coated with sealant.

    Nevertheless, it is necessary to take into account the convenience of laying logs in the combustion chamber: the longer the channel, the more difficult it is to lay logs and then clean the ash box.
