Changes are necessary to keep up with the demands of the gas heater. Additionally, a dedicated circuit as well a heavy gauge wiring are usually required.

For a gas system, the supply valve should be closed but if you have an electric water heater, just unplug the unit from the wall outlet. Remove the old heater then and dispose of it properly.

Prepare your new tankless heater and determine the proper clearances around it. Check your local building codes beforehand for a smooth flow of installation.

If you bought a gas tankless water heater, you will have to install a ventilation duct or exhaust system unlike when having a regular unit with a tank. A larger flue or a stainless steel flue is ideal.

Next, connect your water supply line followed by the heat source. For an electric water heater, simply plug the unit to the wall outlet. But if you’re using a gas unit, install a gas supply line from the stub situated at the wall to the water heater. Open the valve going to the direction of the supply line.

Check for leaks by spraying soapy water on the union. The presence of bubbles signifies poor connection and leakage so you need to double check and repair the problem by first turning off the gas.
