Hi I'm putting a Vigilant in a basement fireplace. The stove has an 8inch oval flue. I have a 8inch oval to 8 inch round adapter, and a 8 inch round to 6 inch round adapter. I also have the two piece plate that sits above the fireplace flue, which is made for an oval flex pipe to go through it. I'm wondering where to get this oval flex pipe. My dad has one. It has a 6 inch round adapter on the side to tie into and a cleanout on the bottom. Then the flex pipe goes up through the adjustable two piece plate for a few feet. Does anyone know any suppliers that sell fire place to stove conversion kits and would have this flex pipe? Thank you
