Furnace Type B Venting


I've done some searching, but haven't come up with much. Just doing some thinking ahead on some future projects. My living room is pretty small, and one way that would help the space quite a bit would be to get rid of the chimney. Right now I have steel tube inside of old chimney, and that's how the furnace is Vented.

I was just curious if Type B venting can be vented through the sidewall of the house or must it be through the roof.

Otherwise I might just end up planning to buy a newer High Efficiency furnace.

Appreciate any help.

Furnace Type B Venting


The code in the area that I worked in did not allow B vent run up the side of a house.If that were the only place to put the flue then it had to be enclosed and the encloser had to be insulated.
The best thing to save money on home heating is to have the furnace sized properly to the individual house.You have a manuel "J" done to size the furnace.
Then you can save more by getting a high effiency furnace of the proper size.When you do that then you can run the PVC vent out the side of the house.
You won't save squat if you get a high effient furnace that is too big.

How is your water heater vented?
Are you going to gain enough floor space to offset the price of a 90plus furnace and a power vent or electric water heater if you nonger have a chimney?
In my personal experiance with home remodels old brick chimneys occupy an area roughly 24" square in the corner of a room,most people dont take into account just how many of those red bricks are actually in a chimmney and how much work it really is to remove them.
Then you also end up with large by huge holes in your roof and ceiling and floor that also need to be dealt with somewhere in the process

Chimney was done in the 70's. It's in an awkward space...shoving the dining room table in the corner. Since I'm in a complete remodel now is the time to do it. Water heater is electric...and considering going tankless. I've told people that once I finish this house the chimney would have been the only thing I didn't modify. Now that might change. I have a good ammount of shingles left over from roofing. Also, no bricks here. Chimney is blocks. Taking out the chimney and going to a HE furnance would allow me to move furnance and change layout of my basement and get some better ductwork. Think I might go for it.
