Drill that small hole and then a 3/8 hole. The manometer comes with a fitting that screws perfectly into a 3/8 hole, then 6 inches of heat resistant rubber hose and then fit the manometer tube into it.

dude......just drill it out!!!!!! :)

manometer install

here is a link for ya, if this link doesn't get to the pic, just go to the second newest page of the thread and scroll down to see an outside and inside view of the flue pipe with the fitting.

In your first post you said you hace an RC Field Controls barometric damper. Understand the purpose of it is to LIMIT the draft, not to increase it. If you are having draft problems, cover you baro with aluminum floil so it cannot suck in any air. Also as Titlest said, open your under fire air more to burn hotter. Once it gets colder you can remove the foil. But without a manometer you are just guessing what your draft is.

Yes! Open one up a bit.

I haven't restarted the fire since the monoxide incident Monday. I see it's supposed to be in the 60's in PA next week. I also wanted to read all the replies again and talk to the place that sold me the stove to make sure I don't make the same mistake again. I'll probably wait until the daytime highs are 50 or below before firing it up again (we have propane as a backup heat).

Thanks again. It's great to get support and advice from other coal burners!

Good to see you are still with us! It gets a little nerve wracking when we don't hear back from somebody with CO issues... :shock:

Not to sound arrogant, but check back with us on what the dealer says. More than one dealer has steered folks wrong when it comes to burning coal.

Get a manometer hooked up, foil over the baro in the shoulder months, crack a window down there, open it up for a little more air from the ash pan air supply to run the stove a little hotter.

Since you have had multiple CO events over the years, play it very safe. Once you get a draft reading of at least .06 for a while you can make small adjustments from there to dial in your efficiency. I used to run my hand fed at .03 - .04 but i wouldn't recommend you do that until you learn your stove / chimney draft personality as measured with a manometer that is connected all the time.

I run mine .02 -.03 Most dealers don't know how to burn coal. You might be lucky though that yours does. Don't let the dealer try to sell you a stainless steel liner. A dealer that sold you the stove might feel obligated to give you advise, even if it's wrong. So be careful.

You will get a variety of opinions on how to fix your issue lol. You are noticing that by now :lol:

I just dialed my baro damper in to hold at 0.04" this morning. It's just cracking open a wee bit at 0.04". I'd be leery of having it opening at less than that. I think the 0.06" advice is good in this case.

A big stove is a challenge in mild weather. You have a lot of coal just smoldering, so CO production is high...and the stack temperature is very low, so the draft is poor. A smaller stove burning hot would be less problematic in mild weather. I understand that having two stoves is not practical for everyone, I just wanted to point out the downfalls of a big stove loafing along on a 50 degree day.

My stove dealer said to always have the ash pan know opened between 1-2 turns (I only had it opened 1/2 turn). He also explained to me negative pressure and to crack open a basement window. He said there needs to be a 200 degree difference between the flue pipe and outside temperature to properly draft.

I also added a kiddie digital readout CO detector to the basement. Now I have 2 in the basement, 1 on the main floor, and one upstairs (only the basement one has a readout-- the other 3 were bought in 2009 when I got the stove).

I agree
Manometer a must
And should have a co monitor

They actually measure low levels of co
Detectors go off at higher levels
Should be mounted around 5 ft in height

If opening a window helps your situation,
I've actually pressurize a basment with a small supply vent to avoid negative pressure
Rather then leave a window open
If your set up allows

Has anyone started a topic on carbon monoxide?
I recently went to a really good co school
It changed a lot of what I thought I knew

I would be willing to share for the safety of all
