Malfunctions, Repairs and Warranty

Cracks in the insulation
The furnace insulation consists of a high-
grade, fire-resistant material. Due to the
thermal expansion, cracks develop in the
insulation after only a few heating cycles.
However, these do not have an influence
on the function or quality of the furnace.
