I am in the process of installing my new Blaze King Princess insert and have a few questions. First, there a few items that came with the insert that i am not sure what they are for. First there was a collar like ring that was around the exhaust exit of the insert when i unpacked it. What is this for? Also, there was a metal rod that kinda looks like a fire poker (90* bend on one end and a handle on the other) that was in the stove. What is this for? Next, should i use furnace cement at the flue connection? After a bunch of cutting/grinding and chipping away the damper and metal support the stove adapter/liner lines up great to the flue collar. Is cement necessary? Next, is it normal for the door to be very tight? seems like the gasket is to large? This is my first new stove so i am not sure if this is normal. Lastly, I stopped my insulation wrap about 6" from the stove adapter. should i wrap the liner all the way down to flue connection? thanks for the help.
