Narrative:
Flight was scheduled to depart ZZZ at XA10 to XXX. Preflight checks were accomplished with no abnormals noted. At approximately XB55, noticed left engine anti-ice right valve open light illuminated. Called maintenance who came out to check. Discussed options with them. I decided I wanted MEL 30-3A valve wired closed. Maintenance then talked to dispatch who wanted MEL 30-3B valve wired open applied. Maintenance performed MEL procedures. On pushback, amended dispatch release was received but noticed MEL 30-3B issued valve wired open. Verified with company on radio MEL 30-3B accepted rerelease. Taxi out, takeoff climb was all normal. Out of 10000 ft, noticed higher than normal oil temperature, but still in the green arc. Out of FL180, oil temperature was in yellow band. That's when I saw left engine fuel heat light on. Confirmed fuel heat on with oil temperature gauge and use of QRH. Elected to return to ZZZ. After 14 mins in yellow arc, shut down left engine per procedures. Declared an emergency and proceeded direct to ZZZ. Landed normally and taxied to gate. Maintenance found left engine fuel heat wired open and not left engine anti-ice.
