    I am still in the process of hooking up my Quadrafire 7100 I bought from a co-worker.It came with two heat zone kits,At least some of the kits. The manual says to use 6" B-Vent only. The kit came with adapter plates that mounted on top of the fireplace box and the B-vent hooks to that and you run B-Vent to the room you want to heat and the blower assy mounts in the wall and the B-Vent hooks to that.. He doesn't have those adapters anymore that mount to the fireplace and I cant find them anyplace.I have searched and searched. Anything else I can use? Anyone have one laying around or know where one can be found?

    If you are handy with tools, an attachment collar can be fabricated from sheet aluminum. I made one for the heat zone on my 6000TRX-I. I cut it to a 3" strip x about 20" long. I formed it into a circle, fitted it into the B-Vent & marked where the end of the overlap was. I returned it to the open condition & laid out 4 mounting tabs 1" x 1" and cut them out with tin snips...I bent the tabs out & re-inserted the collar (now 2" deep) into the B-Vent. I used the B-Vent to hold the shape against the side of the TRX-I & zipscrewed thru the tabs to secure it. Hope I said that in understandable terms...

    I have been a machinist for 25 years and I had trouble following that.LOL Shoot I cant even find any B-Vent around here. I have a lowes about 35 miles from me which I dont mind driving to but cant find anything online on there site about having B-Vent. I am assuming the guy I got this from just used regular uninsulated duct cause I got a bunch of it with the fireplace. But those collars are missing.

    How did you mount that to the 3" hole thats in the top of the fireplace? I call HMI fireplace and wanted to order just that adapter but he said I cant. I would have to order the whole kit for $250.

    3" Hole? The Northstar & the TRX-I have a 6" B-vent take off IIRC. When I told you to bend the tabs outward, that's where I zip screwed into the fire place sheet metal...I used 6" flexible insulated ducting to run from that adapter to the wall, where the blower kit's mounted...
