Baro damper?

no top of stack is higher than house now and if I remove 4 feet.
just noticed with fan off that condensate got worse in hopper.
Really starting to wonder about this coal.

HVAC=
heating-ventilating-air conditioning

checking fan now.

With the combustion blower off you should not get a sulpher smell. Could your door gaskets be fitting that loose ? Or door need adjustment ? Put a dollar bill in the door and close it. Can you pull the bill out with ease at any spot on the door ?

no theres another blower for combustion air.
Yes its a liberty stoker.

no restrictor plate
can not pull out dollar.
Just raised up to medium to medium hi #3. Temps are rising will see.
I think my coal is to wet and maybe also just bad.
Will try to buy some bag coal tomorrow to try.

Also heat travels to cold. a 112 flu 12" above stove seems inadequate. to transfer heat to create draft in these outdoor temps. What can it be 10 feet away even with chimney being insulated.

What is custom about the chimney cap? Are you just talking about the tin that covers the area around the pipe?
The rain topper is just a standard cap right, nothing special?
I can't figure your problem but I think it is something with the chimney not the stove.

Well looks like medium is my smallest operating fire temp. flu goes to 247 draft to .06 and all fumes go away. hopper is still wet but i expevt it to dry again

Will try new coal tomorrow nite as it is going to be 29 degrees here.
Lets see what happens then

When you say your setting is low or medium low fire how big is the red hot coals area on the grate ? With lower quality coal it may not put out enough heat at the lower settings to keep the draft. Try the new coal and let us know.

VERY LITTLE red coal on grate maybe 1"x width 4". no flames.
Assuming my coal is to wet/ How the H do u dry out coal.

The water should make very little if any difference.. most coal is dampened to keep dust under control, The water will evaporate before the coal gets near the actual fire..

If the coal is soaking, dripping wet, you can pour it into five gallon buckets with holes in the bottom, and let the coal drain.. any dryer is not needed..

its not that wet it only gets condensation on it when it is in hopper with stove running.
very perplexing.
Will try bagged coal of no difference than I just cant run stove as low as i would like.

If your coal is not bagged in plastic bags it will dry out on its own. When my stove is at idle I have about 3/4 to 1 inch of red coals and my manometer reads -.02 I am also using outside air for my combustion because of a tight house. Maybe your combustion blower is over powering your draft, drawing air from the baro when your draft is low.

thought about thst am going to put plug in t wher ebaro is tomorrow to see if it drafts better on low. I still think the operating temp on low is to low and flu temp is to low.
Will check temps with Alaska on Monday.

Condensation on the inside of your hopper and hopper lid is usually the result of inadequate draft..

.

thats what Alaska said but it condensates on low at .02 draft. Alaska does however recommend .04 or better. i cant get draft up without increasing size of fire.

Have you taken the draft measurement in the combustion chamber also? It sounds like the combustion fan may be over pressurizing the stove and what the chimney at .04 can't handle is coming out of the hopper. That would explain the condensation andthe sulphur smell.
