sulfer smell!

PostBy: ridgeracing On: Mon Feb 04, 2013 9:36 pm

I was off work today and have noticed a sulfer smell around house. Checked stove out and everything looks OK. After a few hours my Carbon monoxide detector goes off in basement. I closed all vents/doors and opened windows downstairs, reset Co detector and waited half an hour. Closed all windows and has been running as normal for the past hour. Why would I be getting this smell!! I am keeping MPD open just to make sure I am getting a good draft. Any suggestions?

I normally run with my MPD 100% open... I tried running with mine closed at the beginning of the season, and I got the sulfur smell in the house. I also got a reading of 24 ppm on my CO detector, but not high enough to set off the alarm. I believe my problem, though, is that I did not put furnace cement around the collar where the stove pipe fits into the stove. I think with the MPD closed, there is enough room around the crimped pipe that a little bit of flue gas can escape into the room.

My CO detector has not read anything above 0 since I started keeping the MPD wide open.

Another possibility could be fly ash building up, especially if you shake down the stove with the ash door open.

What kind of draw did your manometer indicate that you were getting from the chimney at the time you noticed the sulfur smell?

I would advise anyone with a coal appliance to have a manometer permanently installed, especially if it depends on the natural draw of a chimney. They are cheap and easy to install and always keep you informed about the pressure in the flue pipe. As long as there is negative pressure in the flue pipe, you won't have a carbon monoxide problem. They are especially important when you idle the fire thru warm days and the conditions for a draft failure is most probable. 8-) Also you can choke down your MPD to a precise flue pressure and not be worried that the stove will go positive on the colder days when draft is too strong.

With a manometer installed between the stove and MPD you will never need to guess. As long as there is a negative pressure reading, coal exhaust cannot makes its way out thru any unsealed openings in the pipe joints.

Sorry, no manometer. For the past 2 months I have been shaking it down with MPD closed as well as ash door. After talking to a friend he believes I may have ash build up. My stove chimney goes up 2 ft , 90 bend, horizontal for 2 ft, 90 bend and then up 20ft threw block chimney. I unloaded hopper and plan on burning threw night and cleaning it out tommorow night.

Don't forget some pics, especially if there is heavy ash buildup! :idea:

ridgeracing..... Shaking down with th MPD closed can be the cause of the problem. I always open the MPD and also open the air slots on my ash door all the way and then shake her down. I also have a T with a cap on the horizontal run of the stovepipe before the timble. This way you are able to check if there is any flyash build up in the pipe. Small mirror and a flashlight used in the opening of the T to check it out periodically. All you have to do is remove the cap to check it out.

Alarm just went off in basement. I shut down stove by turning intake dial off. Opened basement windows and closed door and all vents going up stairs. I have to have a clogged chimney, only thing that makes sense? Hopefully I can clean it out tommorow and thats my issue! Yes, a (T) instead of my 90 might be a good idea for mid season clean out and inspection.

I definitely give a +1 on the T instead of a 90. I had some fly ash buildup around the flue collar on my dutchwest last year. I have a T on my DS, I can shine a flashlight in and look past the MPD into the T and the buildup of ash isn't even visible yet after 3.5 months of continuous burning.

shaking down with mpd and ash door closed,your most likely not getting enough draft to carry the fly ash out thru the chimney and the mpd is holding the fly ash in the pipe.

install a tee at the first 90 from the stove,then you can stick a shop vac in and clean out without shutting down,simple and easy 15 minute job

My DUMBASS FAULT! This morning I shut down stove and took chimney piping apart to inspect, everything looked great !, 1/8in. of dusting on pipe but no large amounts at any elbows. But I did notice a nice amount of creosote chunks at bottom of chimney when I had piping out. So tonight I came home and went up on chimney and ran brush down (20ft), went very smooth till I got to about 3ft from bottom, TIGHT! I broke large chunks of creosote from 1st month of burning wood! And this was after I cleaned chimney before start of season. I did not think burning wood for 1 month prior to burning coal I would have so much build up. Cleaned it out real good, re-assemble and burning great!! Big thanks to all for input, always back to the basics ;)

Great man!! I'm glad you found the issue... I don't mean to preach about the mano anymore :oops: but in this case, it would have read a lower draft than normal telling you that the issue was in the chimney somehow, somewhere 8-)

I bet your happy to feel that coal heat again :D

Great that you had a CO alarm and that you caught it.
Something that I was just thinking....This forum is really good about not having condescending replies that beat people up for questions. Other forums I see newbies get beat up pretty good for asking basic questions, but that really doesn't happen here. The only responses (coal related threads) that I see people really get tough about on here is when it comes to CO issues. We really, really don't want any tragedies. now the polijive....that is another story.... :roll: I really enjoy the filter on the 'active' posting I learned about recently....I get to miss all that stuff!

As mentioned earlier i also recommend a manometer permanently hooked up.

You would have probably seen a drop in the draft number as that creosote choked part of the chimney got further clogged with the fly ash.

Once you have been burning for a while you get used to what the draft reading "should" be during different weather conditions and if the draft number isn't near that you start looking. My example is toward the beginning of one season I noticed I couldn't get a draft above .03 no matter what. I knew I should have been able to force it to at least .06 by running it hard and putting foil over the baro given the cold outside temp. After checking many things (including the zeroing of the manometer), I went outside and it turned out the cap on the bottom of my SS chimney had dropped off. I hadn't got it all the way on after cleaning the chimney at the beginning of the season. The low manometer reading tipped me off. I would have been ok until the temps warmed back up a little, if the daytime temps had got up into the 50's with it like that I may have had trouble with CO.

Yes, that is what I was thinking! If I would of had a manometer I would have noticed a drop threw the season and pin pointed issue quicker. I plan on installing one for beginning of next season. I am in the Air Force and dont need these issues going on for my wife and kids when I am deployed!
On a second note- My CO detector down stairs (batt powered) is 5yrs old, that one is the one that went off. Up stairs I have one that is 6 months old (plug in and batt powered), it never went off, I took it down stairs while I had odor and other alarm is going off, this newer one dosent go off at all! When I hit test button it goes off.
I am returning it to Lowes! Why else would this not go off?

Big thank you for your service to our country!!

The new CO detector could be bad. Try taking both out to your car exhaust and see if they read about the same. They recommend replacing them about every 5 years. I have two and rotate out the oldest one so that, like you, they both aren't getting old at the same time.

Dwyer Mark 2 manometer is what i have. They are available on ebay and grainger also sells them. if you have a store close by you can avoid shipping, (i have one nearby in DE so i get to avoid sales tax too!!). couple threads on installation ideas, search manometer and you'll get more info than you need! :)
