Electrical wire zip-tied to the burner...?

[GrandPooba]

Just got a new 80% gas furnace installed. I noticed that there are two wires that have been zip-tied to the black gas pipe that feeds the burners. I'm not sure why this was necessary...

Could the heat from the burners melt the zip-tie and/or the wires themselves?
