January 26, 2025

Do you have a question about the SUF-100-199NE and is the answer not in the manual? Could you send me a manual for this hot water heater. Someone has misplaced the manual that came with it. Would be most appreciative in you could copy of manual to: Dsmith1942216@outlook.com; The water heater is for Church baptistry and we had to boil water early in the morning to get a water temperatre that we could use for baptisms.
