I have had my Monica for 5-6 years. The stove does say ravelli on the glass. My question is on the stove adaptor on the exhaust. This is the first pipe that connects to exhaust. I had always thought this was a part from ravelli. This was due to it not being exactly 3". So Ecoteck provided that adaptor then u would install vent to that. My problem is there is an orange gasket that has failed. I called north forge and they say that is gasket to whatever pipe u used. Of course the dealer I bought from don't sell ravelli anymore. Any thoughts on this
