I've just bought a new house (new to me anyway... it was built in the
late 20's). Got a couple questions.
There is a new (installed last fall) Rheem high eficiency furnace,
which has the 2 pipe setup. One pipe for combustion exhaust, and the
other for fresh air. They aqe both PVC and run through the sidewall.
This is all well and good, but the genius who installed them did it so
the pipes end right above the gas meter outside, and it is already
starting to rust/corrode from the acidic condensation from the vent
pipe dripping on it. I want to move them, and a couple people have
reccomended running them up the old brick chimney (running the pipe
all the way to the top, not just INTO the chimney). This sounds like
the best idea, as the pipes get in the way of a few things the way
they are anyway. The house is only 1 story, so it's not that tall of
Is it feasable to run the PVC pipes up the brick chimney? And what do
I put over the top of the chimney to seal it off and run the pipes
through? Sheet metal maybe? Or ???
I am also going to replace the water heater before we move in. I will
be installing a high efficiency power vent model with PVC vent pipe as
well. Which brings me to my second question.
Can I "Y" the water heater and furnace exhaust vents into 1 going up
the chimney, or do I have to run a separate pipe for the water heater?
any info would be appreciated, thanks...
