New to the coals stoker world. High co numbers

PostBy: vipers95 On: Sat Oct 26, 2013 6:22 pm

Just bought a used Reading Susquehanna two burner stoker. Well got it installed put new stove piping in. Fired it off with both burners set on the coal trol. Seemed to work great. It was 45 degrees in the shop and had the temperature set to 75. It took about 1 hre and 45 min to rise to 75. In about an hr. it ramped down. At that time I could smell sulpher mostly from the rear of the stove. I did not have a co decetor. called it a night and closed the shop. Next morning when I came in could not breath in the shop. BAD CO and sulpher. Went to lowes and got two co detectors. Hooked them up and opened the garage doors and no smell anymore. torned up the thermostat and heat went to 70 . Co detectors were at 0. When it came back to slow burn the one co detector went to 30 and the other one went to still 0. One is set about 4 ft from stoker the other is set 30 ft away from stove. In about 1 hr later the one close to the stove went to 999. the other went to 400.

. Talked to Reading stoves and they said chimney is blocked. IT IS NOT it is all new. When the stoker is running full no problem at all. When it goes back to calling for no heat at idle is where the problem starts. Talked to local old stoker man said block off the draft control. I did that and still the same problem. Have 8" chimney pipe running to ceiling which is about 12' high. there it runs thru Insulated pipe thru the roof and has about 8' of pipe sticking out the roof and about 3 ' over the top of the ridge on the roof. do not have a manometer to measure draft {will get one soo as I can find one]. will enclose photos of the stove.
Have coal tron set to 27max 4 min. tried 8 min and still same results.

I would take the 90s and turn them so they are 45s to straighten the pipe out. Make an offset instead of a sharp turn.

First off, DO NOT BURN THE STOVE AGAIN UNTIL YOU GET A MANOMETER! Those Carbon Monoxide levels can render you unconscious and pushing up daisies pretty quick. Do you have a combustion fan on the stoker that should run all the time? Is there an adjustment for the amount of air the blower blows into the burn chamber? Something needs major adjustment. Is there anything like an exhaust fan creating negative pressure in the shop?

It sounds like the combustion blowers are pressurizing the firebox and pushing flue gasses out. Time to get a draft gauge of some kind, that way you won't be guessing.

Look at the inlet of the combustion blower, there should be something to adjust how much of the opening is exposed. Try closing the shutter 50% and see how it runs. Be very careful, you do NOT want to succumb to CO fumes!

Good idea. One more thought...is there plenty of fresh air available to the room that the stove is in?

Okay, flue is not blocked...but is the flue top above the height of the roof ridgeline?

You didnt by chance block off the chimney with fiberglass insulation to prevent drafts comming in the chimney while hooking up the stove? or maybe this was a unit that sat somewhere and something made a home in the exhaust fan ducting? :gee:

Rob, there are no adjustments for the fire blowers. I culd put tape over them to close them a little. was thinking of that my self. The unit came I purchases used was 3 years old. I went to reading and gor the coaltrol for it. At that time they gave me 2 new combustion blowers. Since the old blowers were driven by the feed motors and would not work with the coal trol. the flame when it is calling for high heat is about 12" tall when it calls for low hear the flame remains the same but the fire is only about 1" wide. at high heat it is ablou 4 to 5" wide. Just pulled the fire pots out. the one on the left had NO rear gasket???
so I do have new gaskets for the pots and will replace them tonight.
will try it again and let you know.

In any case get the manometer. Dwyer Mark II model 25. Amazon has it for $25.

Just put a piece of lit paper in a cold stove and cold chimney. The draft sucked up the flame and all the sparks. I think like rob said it is over pressureizing the stove with the new blowers. Going to replace the gaskets now and close the intake breathers about 50% to start and see how it burns.

What is the direction of the exhaust? It looks like you are going down with the draft, no pitch up.

Tikigeorge, the photo is sideways. The pipe goes essentially, straight up it looks like.

viper
..just curious-
what is the diameter of ur flu pipe ON THE FURNACE ??
...i realize your chimney is 8 inch- but is the stove ??
whats the total height of chimney?
i echo all previous comments- this is serious and needs to be addressed ASAP
...seems to not be drafting on low demand- i suspect chimney (IMO)
...MANO a must

...one more thing-whats the max BTU on tis unit??
is combustion blower ALWAYS running ??

...careful- thats not a true test of draft
...its stack affect of ur shop...
is your shop tight?...the problem shows AFTER running hard(hot)...so idling...ur getting poor draft (or downdraft) if the building is tight
