Hello all! Long time lurker, first time poster. LOTS of great info on this site. Just bought a Breckwell P2700 last week to augment my wood burning fireplace, and the installer will be out on Friday. In looking at the invoice, I do not see a stove adapter listed, only a cleanout increaser tee (from 3" to 4"). The installer plans to use 4" Duravent pipe. Can he attach an increaser tee right to the stove, or did he forget to order a stove adapter? I would like this done right, and on time, and I am worried that if he missed ordering that part, it will be another week or so before the install will take place. Thanks in advance!
