able glass surface cleaning agent – may as well be used for the cleaning of the me-
dium or strongly contaminated glass surfaces of the fireplace. Towards this end, spray
small quantities of the agent to the cold surfaces, spread it, and wash it down with a

Warning: Under no circumstances you may use sponge, scouring, aggressive
or scratching cleaning agents! If the grate is blocked so that the equipment cannot
serve the intended function, the grate is to be removed for cleaning.
