On suggestion of another post, I sent back all the big box brand pellet vent and the liner I didn't like. Reordering all pellet vent pro 4" and duraflex 4" liner. I can't get a straight answer on what's best for connecting the T snout to my stove through an 11" deep masonry horizontal wall. The average snout is 8" long and I've had ideas to connect that snout with a pelletvent pro flex connector to a 12" straight pipe through a thimble I already own, or just order a 12" snout that will stick out the thimble about an inch, and connect with the pellet vent pro connector to that right to the 90 degree elbow. Even though it's more leak points I'm thinking maybe the snout is too thin and will get too hot to be allowed to protrude out of the masonry into the basement? This is the only thing holding me up here. The photos are of the venting I was test fitting before I sent those pieces back because I was very unhappy with the connections. The T will need to be propped on fire brick as there is roughly a 7 inch drop vertically past the masonry hole if I recall correctly. I can elaborate more with specific parts if needed. Thank you folks.
