Masonary wall penetration

englewood1 · 10-06-2007, 07:42 PM

I have a Goodman furnace I installed, now I need to penetrate the masonry structure for the exhaust vent. I have never heard of a 2 1/8" hole saw that will penetrate masonry. Does such a tool exist?

Is the whole building masonary?

Yes, it is brick and masonry and the AC ( air conditioning copper tubes) lines penetrate close to where I have to run the exhaust. The water heater and furnace used to share a common 6" flue to the roof, but you can't tie a forced blower to a natural convection connection, if only I didn't have a gas water heater.

There may be a tool for that size hole. I once had a contractor drill a 4 inch diameter by 6 inch hole through solid concrete. Check with tool rental companys. When I had it done years ago, the contractor charged $60.00 and it was cheaper then renting the tool. I believe you have to rent both the drill motor and the special diamond bit.
I justed check my tool rental book and what you need is called a core drill. This tool can cut holes from 1/2 to 10 inches. There's a company called United Rentals in my area that has it. Go to unitedrentals.com for one near you. Or check the yelow pages for "concrete cutting and core drilling" for a contractor.

I fired it up for 10 to 15 minutes for measurements and the condensate was a milky color coming out of the condensing furnace, is this normal? This was the first start up!
