Wood stove placement

[Linea]

I want to put a wood stove in an addition that has the "exterior" back of the brick chimney in it. I was thinking I could use it for the back of the hearth. There is a gas fire place in the other room. The wood stove would be for when we aren't using the gas unit. This would mean the new stove pipe would exit the roof a couple feet away from the existing chimney.

Is there a problem with this?

Other than aesthetics and allowing enough room in between for proper sealing of the flashing, no. It would be good to terminate the wood stove chimney 18-24" higher than the gas vent to avoid smoke downdrafting into the gas fireplace.

My class A chimney terminates at the same height less than a foot away from the edge of my brick chimney which is attached to a pellet stove. Haven't even been through a winter yet so I don't know if there will be down drafting issues but aesthetically it looks fine.

Other than the mechanics of it's termination in relation to the exterior height of the masonry chimney, I think it would be a great idea and probably look very nice in the room. I dont believe that heat from the stove will matter in any way. You may be able to position the stove pretty close to what is essentially a non-combustible wall. Maybe you can place the chimney pipe out away from the brick chimney and use a 45 elbow offset on the connector to get the stove close to the brick chimney. Pictures would help.

Thanks, that's what I needed.

What is downgrading and what causes it?

What is downgrading and what causes it?

Downdrafting is when there is negative room pressure pulling air down the chimney. This most often occurs when there is a two flue chimney servicing fireplaces on two levels of the house and the chimney terminations are of equal height. The lower fireplace is more likely to be in a negative pressure zone.
