In case of boilers with flame inversion or front flue combustion chambers, it is necessary to insulate the area between the flame tube and front door with refractory material. This protection material must not impede flame tube extraction. MODEL TC TL ** GM X5/2 mm 250 335 ** For different flame tube lengths, please contact our Technical-Sales Department.
