Taller water heater, need to drill hole in chimney

Hi everyone,

My water heater started leaking out the bottom so I knew it was time for a new one. I brought home the new one knowing it was 4" taller than the old one but didn't realize that the current hole in the chimney is level with our current water heater. Of course this means that I can't use it with the new water heater. So I have three options, return the water heater for a shorter one, call someone in to install it, or punch a new hole myself.

I thought I could probably rent a core saw or something to do the job, my concern is the clay liner in the chimney. I realize that if I break it I won't be saving any money on this "do it yourself" project.

My question is how do I drill a three inch hole in my chimney with a clay liner?

Thanks for any advice

Return the heater for a low boy is your best option....

Cutting a new hole is a PITA and you may have issues if a furnace/boiler feeds in from below.
