Is it safe and legal to vent a stove pipe 90 degrees down at the exhaust port of the stove and then straight back into the fireplace and then 90 degrees up the flu cause the stove exhaust port is higher than the fireplace opening? Dont really want to cut a hole in the wall over the fireplace.

No, not because it's illegal but because it's very, very unsafe. Your chimney may not be able to draft the exhaust gasses down then back up. There is an increased chance of the stove venting Co2 back into your living space. If it were my stove, I'd cut a second flue opening or run a new Metalbestos chimney through the ceiling and roof.

Is it safe to have multiple flue opening in a chimney as long as you have the other capped off temporaraly? I've wondered about this because I could then make a flue in my dining room and cap off the one upstairs in the bed room.I'm On Fire wrote:No, not because it's illegal but because it's very, very unsafe.

As far as I know you can do that. You can even use both flues as long as the fuel us the same for each appliance. I wouldn't permanently block off the second flue on the second floor just in case you want to put another coal stove there.
I am not sure what stove your trying to install in this certain situation but do you have any options of lowering the stove with a shorter style base or legs ?PJT wrote:Is it safe and legal to vent a stove pipe 90 degrees down at the exhaust port of the stove and then straight back into the fireplace and then 90 degrees up the flu cause the stove exhaust port is higher than the fireplace opening?

Personally I would not feel comfortable by putting any negative grade in a chimney or flue pipe.

This is very good news! I can only burn coal in the other two chimneys because it's the terracotta square lined lined and I don't want to take the chance of a chimney fire.I'm On Fire wrote:As far as I know you can do that.

It's not hard to make a new flue in a masonry chimney. It can easily be bricked back in if you ever want to sell or use just the fireplace again.PJT wrote:Is it safe and legal to vent a stove pipe 90 degrees down at the exhaust port of the stove and then straight back into the fireplace and then 90 degrees up the flu cause the stove exhaust port is higher than the fireplace opening?

OK let me play Devil's advocate here....how is putting a negative grade on the flu pipe any different than running a base heater in base heating mode? Lots of negative grade on the flu there....
Not trying to be argumentative just trying to understand how all this works Thank you everyone for your help!

I personally do not put my baseheater in baseheater mode until the fire is well estabished and the draft is established from the flue being heated when in direct draft mode.PJT wrote:OK let me play Devil's advocate here....how is putting a negative grade on the flu pipe any different than running a base heater in base heating mode?

Now if the outside temps are warm and it is damp this may restrict your draft even more (it does on mine), I have actually thought I would have to take it out of baseheater mode when temps are in the 60's to continue to get the draft needed on those type of days and had I been away from the house at work I probably would have went to direct draft due to the dogs being here and no one to keep an eye on the stove. I may be overly cautious but better safe than sorry. Just my thoughts though.
