Optimal combustion air flow inside the firebox is necessary for keeping the viewing glass clean. In BRUNNER fireplaces, air supply can be adjusted to existing chimney draught, creating a protective air screen, which prevents soot & dust build-up on the viewing glass surface. If the gap between door and body of the fireplace is tight, the air screen is not disrupted. The viewing glass surface is free from stains.
A combination of our 'easy-lift' door lifting system and 'puzzle profile' door frame including a special seal is a long-lasting protection against air leaks between fireplace door and body. That's our secret of clean viewing glass!
What is more: Individual adjustment of combustion air supply is available only from BRUNNER.
