RE: Adding a damper

[firefighterjake]

It doesn't happen often -- maybe 3-5 times a year -- but once in a while my stove starts getting hotter and hotter and the only way I can slow it down is to fully or partially block the secondary air hole with tin foil. It's not a big deal for me when I'm home, but I've been thinking that adding a damper a) might be easier for my wife and b) I might be able to get longer burns.

Not sure how I can easily do this though. Set up is as follows: Adapter to double wall pipe and then out through the wall thimble. I've seen that ICC sells a damper for double wall pipe, but it appears to me that this would give me another 6 inch rise in the stove pipe . . . which would not work.

I'm guessing there is a very simple answer here . . . telescoping pipe? flue sold at a different length? a method to install the damper in the existing double wall pipe?

Hi Jake, I didn't bother giving any updates on my secondary air control but it really does work very well on those occasions when I need a little more control and it allows me to fine tune what is going on in the firebox. It isn't difficult to make and might be a good option for you if the damper isn't possible.

For double-wall connector usually one has to add a factory damper pre-installed in a 6" section of connector. You have it correct Jake. In this case it would mean replacing the current vertical pipe with on that is 6" shorter or with a telescoping section.

I remember when you posted this . . . but I pretty much had forgotten all about it until you put up this link. I may try experimenting with this first . . . especially since it seems like this may be just the thing for me to try on those infrequent times I need to dial down things down a bit. Thank you for posting this . . . much appreciated.

Thank you for the confirmation . . . just wanted to be sure I wasn't missing something.

No problem, I hope it works out for you, If you have any questions don't hesitate to ask. The only thing I would do a little different now is I'd make the tabs that I bent around the air intake to connect it a little more substantial. Make them a little wider and a little longer and add a few more.
