co built up

140 coal stoker alaska even when running one burner only half power or on 40 co builts up after 3 to 4 hours stove brand new also pipe and chimmey

what kind of chimney or power vent do you have? you have a leak somewhere! CO is NOTHING to mess with. you need to check your chimney, seals, etc....

How do you know it is CO? Do you have a detector? Try opening a window a bit if your house is very tight. You need a manometer to check draft.

take a stick of insense and look around the doors for a leak. I found way in the corner of the glass that the gasket had slipped a bit once. the detectors went off! well one of the three did a little tightning of the screw that holds it in fixed it

its a block chimmet with clay flue think i smell exhaust gaes when blower kicks on have 2 vent in wall to outside plus cold air return above stove off to side bout 3 ft going to get a draft inducer soon as i check everything u all suggested thanks everyone

Is there an air adjustment on the combustion blower? Have you checked the draft?

I recommend checking the draft with a gauge before investing in a draft inducer. How is the Baro adjusted also you may be able to cycle the stoker a little more often to keep heat in the chimney.

Another vote to check your draft with a manometer. you should check draft in the firebox as well as the flue pipe. If your firebox draft is higher than the flue pipe draft reading the exhaust will look to escape other places like a hopper, door seals, etc. Are you able to adjust the amount of combustion air going into the stoker? My harman stoker has a plate on the combustion fan intake that allows me to limit the air, if it was wide open it would pressurize the firebox and i would get exhaust that couldn't get out the flue pipe escaping into the basement. If you don't have a plate to cover it, a refrigerator magnet has been used by some members to partially cover the fan intake for this purpose.

Do you have any moisture on the inside of your hopper lid?

Always ere on the safe side when suspecting CO.

No alarms? New stove? The paint curing and oil residue from new steel will off gas smoke/fumes for the first few fires. This is common with all new stoves.

So it wasn't CO at all...just an accelerated paint cure taking place due to not enough heat getting washed off by too little fan air.

it was co since air return was too small blower would suck air from damper and send it in house thu duct work
