I have purchased a Breckwell P24 and have had it for about 24 months and now getting around to installing. Here is my issue and wanted to see if anyone has done this or has any ideas. In the center of the stove it has an approximate 3" cut out with plate for vertical install up through the stove. In reading the manual, it says to do this you need a part "A-VIK" (vertical install kit). I have called no less that 25 places to find one of these and no one has the part listed or can tell me how to get one. Even though it shows in the manual as a part. I could come out behind the stove and come up with a tee but that takes about 5 inches of space I can ill afford to lose. My first question would be can anyone tell me how to get this part or has gotten this part? If not can anyone tell me if they have done a vertical install up thru the stove and what pipe they used to do it. In the picture in the manual it looks like a flexible pipe but don't know any specs on it. I would assume it is a double wall PV flex pipe but don't see any after market pipe that would really work. Thanks so much for your help in advance.
