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 **** K X5/2 mm 250 315 **** For different flame lengths, please contact our Technical-Sales Department.
