Floor Furnace Vent pipe
4 Attachment(s)
I was under the house looking for termite damage when I saw these two pipes weren't connected. This is our floor furnace in our 1929 house. I have no idea how old this furnace is but it's a work horse. This disconnect, however, is very unsettling. Is it safe to maneuver these 2 pipes together and then what kind of tape do I need to secure it? I can't quite make out the letters on the old tape.
(We moved into this house about 3 yrs ago and when we first moved in a guy theoretically repaired this.) And is that other thing asbestos?:eek:
Thanks in advance,

Its probably asbestos.

That flue pipe is suppose to be screwed together, not taped.

Ohhhh. So what's the best solution for this?

Run whole need vent pipe. it should have been ran in B vent, not single wall.

If you can't find a local asbestos company. There are ways to get it off the pipe without it floating into the air.

Not sure what "Run whole need vent pipe" means. And what is meant by "B vent vs. single wall". Thanks.

agree with bt ,,but why have you not considered a new furnace due to the age of this bomb and the unsafe condition that now exist and the cost to repair that condition.....imo replace furnace...ben sr

Didn't really think about replacing it. Originally just thought it needed to be taped up. There's the fine balance of do we want to go central heat and air. Before this incident of the displaced pipes (which I think was caused by an unhappy possum that snuck under our house) We had it checked at the beginning of the winter and they said it worked great. No leaks. Etc.

If that is an open vent line to the chimney, running it as it is can kill you with CO.
Not only is it open and taped instead of screwed but all the other joints look like they are leaking precipitate.
Replace that c vent with b vent.

Yikes! The vent line doesn't go to the chimney, but it does go to the roof. Right now, the gas/pilot light is off.

Whoever you got to go under there and claimed it was ok, don't call them again because they don't know what they're doing and potentially put your whole family at risk. Do not turn the furnace back on until that venting at least has been replaced by someone fully qualified.

You need a qualified HVAC professional to come and look things over. Those old floor furnaces if maintained properly would last a long time. Of course they're not very efficient and won't be usable for central air.

Get an estimate for fixing what you have along with one for upgrading to what you are thinking you might like and weigh your options.

If the crawlspace or the attic is the only possible location for your new heating system also, then make sure you hire whoever explains to you all of the positives and negatives of each and what they will do to make sure a new system is as energy efficient, sealed properly and insulated above and beyond minimum.

Add whatever is needed in the form of barriers to keep animals from under your home also. They cause damage and can carry diseases that again are not safe for you and your family.

Good Luck.

Thanks Old S. We'll start making the phone calls now.

Here are more pictures. It looks like it is indeed a Type B vent pipe. 2 pictures show where it's hooked up to the vent that goes up to the roof.

Does this change any thoughts?
