I want to use black Selkirk DT vent pipe to give my upstairs 2nd stove a wood stove look and also a convienent OAK connection. The stove will vent out a clay thimble into an unused flue I had put in when the house was built and then into flex vent out to the termination at the top of the chimney. I think I have good handle on everything I need except for the Selkirk DT to clay thimble to flex connection. I can't figure that part out based on Selkirk's literature. They make a 'Masonary Chimney Conversion Kit' (4DT-MCK) but I'm not sure how that fits in or if it's even the right part for the job. I also want to incorporate a 45 deg elbow at the stove to try to center the vent on the stove. I don't have pictures (yet ) but will put some up as I proceed. Meanwhile I will describe what I think I need, starting at the stove. Please correct me if I got it wrong and help fill in where you can. 1) stove 2) appliance adapter (3VP-PC???) 3) horizontal 45 deg elbow (3VP45EL) 4) vertical 3" to 4" clean out tee (4VP3T) 5) vertical pellet to DT pipe adapter (4DT-VPSA) 6) vertical length of DT pipe/adjustable pipe 7) 90 deg elbow to masonary thimble (4DT-EL90SB) 8) something to connect the 90 deg elbow 9) something to pass through the clay thimble 10) something to connect to the flex vent 11) flex vent (which I already own) up the flue 12) termination (something to allow OAK air into the flue) I've seen 2 part flex connectors made for connecting inside the flue where there is no access. They work by connecting 1 part into the end of the flex and dropping it down the flue and the 2nd part goes into the clay thimble and connects with the 1st part, forming the tee inside the flue. Is there something like that that works with Selkirk DT? EDIT: like this, about 1 minute in: I plan to draw OAK air from the flue so if I use the Selkirk 'Masonary Chimney Conversion Kit' (4DT-MCK) will that be my OAK air inlet?
