I purchased a brand new sunrise metals 2x6 drop flue from the maple guys. I am thrilled to be moving up from the half pint. Now I have to sell the little guy and stuff the big guy into my 12x8 shack. I'm expecting it to be a bit on the steamy side in there this spring. It was steamy doing 6to8gph this units advertised at 37 Chris said I should be over 40 with a blower. Mirror finish on the pans and stainless sides on the arch. Couldn't be any happier.
