I have had this Vermont Castings Winter Warmer for about four years now and every since it's installation the front glass has had a carbon build up issue. This year I replaced the catalyst and the front door gasket during the annual cleaning. Today, we fired up the unit and after only three hours of burning the glass is already covering with carbon. Always starts at the lower left corner and builds it's way up the glass. We clean it off each morning and it is a pain for sure.
We have tried different air levels, smaller amounts of burning wood etc and nothing seems to help. The vendor is useless in his responses. Can anyone suggest what we are doing wrong or what a solution might be.
