I am replacing an existing gas logs with a new set.
The existing had a copper pipe from the wall of the ceramic box
And a shutoff valve it ran under the existing logs about 1 foot
To the other side of box to the controls.

The new logs I bought a flexible stainless steel pipe that says
It OK for use for dryer and gas logs, but I was wondering if it was OK
To be inside the box, or would it get too hot or would the heat affect it?
