I read one post saying that the airflow locations are the same for the 13-NC (Englander) and the NC30 (and there are a lot of post about the NC30 and its 3 airflow locations). But on my 13-NC (less discussed on this forum) I can't find any holes behind the front legs.

Can anybody share the locations of the different air intakes on the 13-NC? Is it just the damper and the 3" round hold on the back? After reading many posts here about how to tame a fast burning NC30, I was hoping that 13-NC was the same and I could put magnets over the 2 small holes behind the front legs to slow down the air coming through the doghouse. I already tried covering 2/3 of the 3" round hole on the rear for the airwash (or is it for doghouse or the secondaries?), but it doesn't slow down my burn at all. The dog house still has air flying through it and it fuels heavy/glowing burn at all times even with the damper closed. FYI I have a very tall chimney and I don't think I have enough room above the stove to install a pipe damper (it's installed in a small fireplace).

I am not using legs or the pedestal - due to a small fireplace I have this sitting on firebricks which are only underneath the lowest part of the stove (the damper box). See photo. Thus I can fully access the higher areas going from the front corners to the rear corners (where the holes are on an NC30), but I can't feel any holes up in there on my 13-NC. I can't imagine that the holes would be on the underside of the damper casing, since if the bricks were covering the holes, then I wouldn't have this problem of too much air in the doghouse.

Mine is running away lately, especially since I installed another section of vertical chimney pipe to be double-sure I had enough clearance to the roofline. Doing some inquiry on it and will report back if I figure anything out.

Check to make sure your door seal is still tight (dollar bill test) and if its ok then you probably want to install a manual damper (key damper) in the stovepipe to get things back under control.

There are 4 holes on the NC30. Two behind the front legs, the big 3" hole, and then the rectangle (1"x2") hole for the secondary right next to the big 3" hole.

You said that you partially (2/3) blocked the big 3" hole. Well why not block it fully? At least for test purposes?

I replaced the door gasket recently and checked the seals; it's tight (I'm not the OP). There are no air inlets by the legs of my 13-NC. The only only one I can find is the primary intake in the back of the stove. The main pipe coming off of my stove is double walled 6". Can this properly accommodate an aftermarket damper?

It's best in that case to buy the damper made for the pipe. Typically they come built into a 6" length of their double-wall stovepipe.
