How to Install Tank less water Heater Turn off main incoming water line to house. Disconnect supply line from old water heater. You will probably have some water left in the line even though your main has been shut off. Place a bucket underneath water bib to catch any spills. Once you have completely disconnected the old water heater you must remove it from its current parking space and make sure to dispose of it according to the laws in the area you live in. Remove your new tank less water heater from the carton and place all hardware and instructional material close at hand. Determine the location best suited for this appliance and make sure you have allowed for the proper clearances around it. Mount tank less heater on wall according to instructions, making sure that you have appropriately supported its weight. Now you're ready to hook up all the connections.
