This is my first new thread. I have been looking for a thread already open for this but haven't found one.
So I got a Hampton HL300 insert earlier this year. I just used roxul and sheet metal to install a block off plate, which everyone seems to agree is a must. My chimney is an exterior chimney. I asked the installer about it when they installed it. His response was I didn't need one. When installing they seal off the top with cement. And the block off plate is for when you use a metal cap. My response was, doesn't the exterior brick suck the heat and the block off plate would stop the heat from rising and being wasted. I got tired of arguing with him so I just did it myself. The only reason I had them install is for insurance perposes if anything were to happen either they would be responsible or my insurance would pay and not try to say it was something I did.
That being said. I start a small fire with kindling and a few small splits to get the unit warmed up and nice hot coals. Move them to the front and load east to west. I fill the box up with medium sized to large splits. I put the largest one in the back and build forward. I leave a gap on the top by not loading past the bricks. I read that it needs a gap for the secondaries to work correctly. I also don't load past the bricks in the front although some of the coals I rake to the front are past right in the front. Side question... Should I keep them on the brick as well? I currently bring the wood to the front edge of the brick. And then I put a couple smaller splits right on top of the coals. The fire start up pretty quickly with the door cracked then I shut it. When the wood is charred on the top I start backing the air down till I get lazy flames. Usually it about 1/4 then I leave them get quick again and back it down some more. Last couple fires I need to leave it half way out or a little more to keep good secondaries. My temps (measuring from the top of the fire box right between the air gap on the top) top out around 550-600 maybe a little more then they drop slowly over the burn. When the fire goes out the log at the back is usually not burn through. Last night when it stopped the bottom back two were not burn through. I tried closing the air down a little more last night. I was probably little under halfway to 3/4 closed.
When starting I can close the air down all the way and get good burn and secondaries. But when the top row burns through the fire goes out. So have been playing with the air controls trying to figure this out. Like I said above I find best luck with complete burn when keeping the air 1/2 way open or more.
Can I get some opinions please.
O ya I have a 6 inch liner I believe double wall and I know it is insulated. I just installed the block off plate at the dampener. My chimney is pretty short. I live in a colonial 2 story house. The chimney goes almost up the the top roof but is attached the to the room with lower roof. I would say 25-30 feet. At the crown it is sealed off with cement.
