Color of ashes

I’m sure this question is going to sound ridiculous but my dad passed away and I am trying to help my mom because the wood stove makes her nervous (my dad did all ththat stuff).

We noticed the wood is burning into really white ashes compared to the darker grey it was before. 

Is it maybe just the different kinds of wood being burnt?

wood furnace automatic damper adjustment

Seven inch metal stove pipe attached to brick chimney.

In the vertical part of the pipe is the damper assembly. It is a T shape short pipe section, with the open leg facing out. At the open T end is the damper flap, mounted on two swivel hinges.

The flap is free to swing on these little hinge things. In the center of the damper is the adjustment mechanism - a threaded shaft with a nut like weight threaded onto the shaft.

Screw the weight in, the flapper stays more easily closed. Screw it out-the weight tends to open the flapper.

Lots of draft to the fire, the damper tends to close. Little draft to the fire, the flapper tends to open.


How does one adjust this damper with the weight to get the most efficient burn??? I installed this twenty years ago. It worked fine. Now some kids fiddled with it, so I have no idea where it was set.

2 fireplaces, 1 flue - smoke leak

MD, United States

I have 2 fireplaces, 1 on 1st floor and 1 directly below it in the basement.

Both are on the same flue/chimney. When I have a fire upstairs there is significant smoke seepage into the basement. The only solutions that worked were a chimney balloon, with limited success and need to re-inflate constantly, and current mode of sealing it up with insulation panels/caulking.

That’s a short-term fix. Would love to use this fireplace but the balloon is a mess to insert/remove constantly. Would new doors with gaskets work? Currently has the standard glass bi-folds (pro baby builder grade).

Looking to stop the seepage but keep the fireplace functional. Willing to do some adjustments on use each time but chimney balloon is not idea.


Note: This isn’t an issue with priming, I’m well aware of doing that properly.

Fireplace 1 causes smoke in fireplace 2

I have an old colonial that was renovated (spray foam, very tight).  I had a moron mason rebuild the center chimney.  I have a large kitchen fireplace that has two flues and a brick oven (separate flue). 

Behind it in the parlor is another fireplace (separate flue). 

Upstairs I have two bedrooms each with a small fireplace (each has its own flue). 

When I light the kitchen fireplace I can smell smoke in one of the bedrooms. 

The chimney has new dampers on the top of the chimney.  Smoke can be seen in the flue. 

If I open the bedroom flue smoke pours in. 

I called a chimney sweep and he indicated the top dampers look sealed and suggested installing a liner in the big fireplace because the clay pipe might be cracked and its leaking into the chimney. 

Does this sound correct? 

I already paid a ton of money on the chimney. there is an air vent in each chimney put it does not appear to be pulling air in.

Smoke entering the room.

I have a large open wood burning fireplace in our living room. It is adjacent to an outside wall.

The fire burns really well and very hot. However the moment I close the door to the room smoke enters the room. I can literally control the smoke by opening and closing the door.

It’s a large fire so i imagine it needs a huge amount of oxygen. however I’m just surprised the smoke entry into the room is so instantaneous when I close the door.

Do you have any idea why this is happening?

I am thinking the room is quite air tight.

Larger pipe to smaller

I have an older Earthstove wood burner than has a 9 inch pipe leaving the stove and exits through the ceiling and roof. I would like to replace it with more modern woodburner. They all seem to have much smaller diameter stove-pipes these days (5-6 inches). What am I looking at to run a smaller pipe the same route as the older 9 inch?

Smoke throughout house…

We have a 1711 home with one central chimney and 4 flus within. We recently had a cap put on top of the chimney and two exterior dampers installed to two of the four flus. We now get smoke throughout the first floor when we burn a fire in the living room. Is there anyway to avoid this. The house now smells smokey all the time!
We also had all new, energy efficient windows installed.
Is all of the above contributing to the problem?

Optimal Chimney Temperature?

Alabama, United States

I have a smaller, non-cat, cast iron wood burner with approx. 6’ of single wall black pipe and 9’ of insulated double-wall chimney above.

I’m trying to minimize creosote build-up.

Is there a recommended operating temperature I should maintain or not go below.

I have an infra-red thermometer, so I can take readings anywhere on the stove and along the black pipe pretty easily.

wooden beams and wiring next to brick chimney

Massachusetts, United States

I have a brick chimney with clay liner.

About 35 years ago the chimney was used as a chase to run wires to the upper floors. The chimney now needs to be relined.

Will a cast in place liner or a double walled metal liner give me the insulation needed for the wiring and the beams that are in contact with the brick?
