New Stove Pipe & Barametric Damper Questions

New Stove Pipe & Barametric Damper Questions

PostBy: jimker On: Sat Sep 06, 2008 4:28 pm

I'm installing my Harman Magnum Stoker in the location of my old wood stove. I've got a 16' vertical run to the top of my chimney and have two questions:

1. Do I really need a barametric damper or is it only recommended. The first dealer that I spoke with said yes. The 2nd dealer where I bought the stove said no. Is the damper strictly for efficiency or is it more of a safey concern?

2. The connection where the stove pipe attaches to the stove does not have a tight fit, even after attaching 3 screws to fasten the pipe. The stove has a 6" connection and I've got 6" 24ga snap-lock pipe. Do I need a special stovetop adapter or a different type of pipe? I can fill the gap with some cement, but I'm not sure if that's the best thing. Also, I tried flipping the pipe upside down and confirmed that the non-crimped end fits better in the top of the stove, however, it does not have the "flared" ring above the crimp. Does that matter?

Kind of for both. With it and a manometer setup correctly it should give you the most efficiency from your stove. More bank for your buck by not wasting any extra going up the chimney. Safety becuase you'll sleep better knowing that all that CO is going out the chimney and not into your home if the wind should some how create a down draft in your chimney. It's always nice knowing everyone will be waking up the next morning. ;)

Yes on the baro, it also depends on your chimney and drafting. In some instances, you might be able to get away without it, but as the weather gets colder and your stove is running hotter, the draft will increase and suck more heat from the stove, the baro will open and maintain a constant draw on the stove keeping it as it's best efficiency and not wasting fuel or wasting heat up the chimeny.

You can seal with hi-temp silicone also, but it should be screwed together and sealed.

I don't know anything about a Mag stoker but with other stoker stoves if you do not have a baro you can draw too much air through the stove and cause a hopper fire. Maybe something to look into.
