We originally planned on going in the side, but through the floor is much more
direct with no need to run a pipe on the outside wall of the house. Do you
think it's possible/wise to continue drilling?

There could be a steel pan filled with concrete under the firebox and
in front of it. My gas pipe goes out the side and I think that is
where gas logs and inserts expect it.

We have a woodburning fireplace we are converting to gas logs. I am
trying to drill a hole to accommodate the gas pipe through the floor
in a front corner of the firebox to a utility space under the house.
I get through the firebrick, about 3 1/2", and then hit something my
carbide bit cannot penetrate.

Does anyone have a suggestion how to detect what I'm hitting? Do
they use steel plate reinforcement in fireplace construction? Any
help is appreciated.
