Gas and Oil Home Heating Furnaces - gas hazard?

I cut holes for some recessed lighting in my ceiling. The lights are 6" cans and are IC for sitting directly against insulation. The problem is I noticed pretty much exactly on the can hole edge is some copper colored piping probably leading from the furnace in the attic to the adjoining kitchen. I can't slide the hole over because of a joist so I am stuck placing the can directly against this copper colored tubing which is at about 1/2 way up the can height.

The question is this- Is this a fire/electrical/gas hazard? My guess is that since the can is IC rated and can sit against insulation it doesnt get hot enough to start a fire so it shoudn't be an issue. The electrical housing for the can is contained in a closed box as can be slid away from the tubing at least 8"-12" or so....

Any thoughts?

I think that gas pipes in a house are usually black iron pipe. I would suspect that the copper colored tubing is a condensate drain line from the furnace to the kitchen sink drain. Do some tracking. If it is a condensate line, you may be okay.
