Barometric damper wont fit into DuraVent 6DVL-T tee.

Barometric damper wont fit into DuraVent 6DVL-T tee.

PostBy: Maro On: Fri Sep 20, 2013 9:39 am

My Hitzer 50-93 (just purchased) has a DuraVent 6DVL-T ( 6 in. tee) for the barometric damper. My supplier gave me a Field Controls 6 in. RC STD barometric damper to go with the tee. However, I cannot yet find a way to install the damper into the tee because the the diameter of the damper is the same as the inside diameter of the tee,s inner wall. Also the damper diameter has an 1/8 inch lip 3/4 inch from the end that gets inserted. The DuraVent catalog states that this tee is for barometric damper installations. I called one of my suppliers and they did not know how to remedy this issue. Is there an adapter for the damper or have I missed something ? :?

DuraVent may make an adapter that bridges between the two.

Don't know why you're even bothering with the baro in your 30-95????????????????

Well Fred , I've got some folks telling me I must have a baro and others telling me I will need either a baro or a conventional flu damper. One supplier tells me I need a baro to guard against carbon monoxide gas escaping into the house. Please remember that I am new to coal ( said good bye to burning wood this year ). Please enlighten me as to why I won't need a baro. I'm all ears.

Barometric or Manual damper is mostly preference. When I first started burning coal, I only had a manual damper installed. My problem was that I couldn't achieve a steady heat output. It was constantly yo yo-ing. I'd close the primary air feed a little and temp would spiral downward. Then I'd open it a little and the temp would climb to hot. A barometric damper solved all this madness. Now I get a 12 hour burn with only a few degrees of variance thru the whole burn time.

That's the purpose of a barometric damper. It regulates the negative pressure in the fire box which makes for consistent heat output.

There is endless controversy over the two dampers. Fred uses a manual. During severe cold temps outside I use a combination of both. But mostly I let the barometric run the show.

I should also add that some stoves are equipped with a thermostat that mechanically opens and closes which helps it maintain a consistent heat output. I think Fred's has one on his.

This device kinda achieves the same goal maintaining consistent heat output.

It really depends upon the stove. some stoves do very well with one or the other - I have only a manual damper, I get perfectly steady heat output... But if I had your stove, I'd probably need the baro... And, I get way beyond a 12 hour burn unless I'm flat out in the coldest part of the winter then I get more like 14 hours...It's all stove dependent... I've never run the 50-93 the original poster is installing... those that run them should say what works best for them...

Ahhhh, you do have the 50-93--as Lee said--I only run the MPD & yes the metallic thermo that you & I have make for a much controllable burn--I've never had a problem draft wise in my 50-93 with the MPD & I question your dealers knowledge regarding CO gas's getting into the house without the Baro. You do what you feel comfortable with--my personal experience goes with the MPD on our particular stoves. Maro, update your profile on stove type---ya threw me off

To everyone,
Thanks a bunch for the input/info. I have often found that some of the best info on any topic is found at the grass roots levels, and that happens to be you folks. Fred, sorry bout the profile error. I just updated it. I was gonna buy the 30-95 but I took one posters advice and bought the 50-93. I found a good deal on a 50-93 with only 1 1/2 seasons on it. By the way, I did get the baro into the tee after a supplier lightly crimped the baro collar for me. It fits nice and snug. For now I got the local installation permit and I'm just finishing up on connecting the stove pipe ( DuraVent DVL ) to my previous DuraVent chimney that was used with my wood stove. I'm glad that I bought their all fuel SS for the wood burner. It spared me from a new chimney installation. Anyways, I can't wait for colder weather so I can fire it up. I never thought I'd wish for colder weather in Syracuse.
Thanks again.
