Installing a Gas Water Heater

By closing all valves and draining the water, remove the old water heater.

You must disconnect the pipes from the old hot water heater, shut off each valve, and drain the water before replacing it. Follow these steps to remove an outdated heater:

 

At the heater’s top, close the cold water valve.

Switch off the gas valve and shut off the heater’s electric supply at the circuit breaker; keep an eye on the pilot light to make sure no gas is still present.

Let the water flow into a drain by connecting a hose to the drainage pipe.
The vent shaft at the top of the heater should be unscrewed and disconnected.
Utilize a pipe wrench or tubing cutter to remove any remaining unions.
Place the heater on a forklift or lifting trolley, load it into your truck, and transport it to the designated disposal site. If you are unable to move it yourself, think about using a removal service.

Place the new heater atop the blocks with the pipes facing outward.

To the water inlet on the heater's top, solder fresh copper adapters.

You must disconnect the pipes from the old hot water heater, shut off each valve, and drain the water before replacing it. Follow these steps to remove an outdated heater:

 

Solder a new adaptor to one open end of a pipe made of 6 in (15 cm) copper pipes so that it will fit properly into the water intake above the heater. To firmly secure the connection, use a pipe wrench. A red ring should surround the hot water output, and a blue ring should surround the cold water intake.
Attach a plastic lining “nipple” to the top of the intake valve if your area has extremely hard water or if your city mandates it to further control the water quality.

Connect the water lines to the heater's top.

Align the water pipes coming from the ceiling or wall with the copper pipes extending from the intake valve on top of your new heater. After that, solder copper connectors to the pipes.
If they are not parallel, solder elbow joints to the copper pipes of the water heater to make them align.

Upon the heater's draft hood, reattach the vent shaft.

Place the draft hood over the vent firmly and insert three-quarter-inch (1.9 cm) screws into it to attach it to the heater. Re-adjust the vent as necessary; it should be at least 1 foot (0.30 m) high before bending.
The draft hood’s holes should ideally be pre-drilled to make it easier to match the vent shaft with the draft hood.

reconnect the gas valve's gas line.

Apply pipe joint compound to the steel pipe’s ends before screwing one end into the gas valve. After that, set it in place on the tank and attach it to the gas line. To lessen the strain on the gas valve, use two wrenches; keep one on the valve itself to steady it and the other to turn it. Cover the connection of the gas valve and the gas intake with plastic to keep it secure.

Turn on a faucet and fill the new tank with water to check for leaks.

Open the cold water valve while turning on the water at the main shutoff. Hot-water the nearest faucet, then wait for the heater to come on. After that, check each heater joint to ensure there are no leaks.[8] Turn off the gas valve and the faucet if you smell gas, wait a few hours, and then solder the connection. You risk igniting the gas in the air if you don’t wait.
Tightening the connections or soldering the pipes can stop water and gas leaks. Then, try again after tightening or soldering the loose connection.
The heater is turned on even if the pilot light is off by turning on the hot water throughout the house.
