How to Install a 50-Gallon Gas Water Heater

Here’s a step-by-step guide on how to install a 50-gallon gas water heater 

  1. Before installing the gas water heater, check the codes of the local building. Make sure to observe the specifications and energy utilization of the heater also.

  2. Now, choose the appropriate place where you will be installing the tank. You need to avoid any situation that might cause flooding. This can be done by connecting a drain pipe.

  3. After choosing the place and drain pipes, you need to fit the discharge pipe to the temperature and pressure relief valve. These valves turn on when the pressure and temperature of the tank are very high. If you don’t have any proper drainage beneath this pipe, then you can place a bucket under it. The pipe should be six inches or less above the bucket.

  4. Buy a flexible hose kit, which must include a gas hose. Apply plumber's tape on the top where you will connect the hose. Now, fix the hose in these inlets.  

  5. Connect the hose and pipe by using the compression knot. For the stronger grip of the heater, you can also connect it by using the seismic straps. 

  6. Now remove any air bubbles from the faucet nearest to the tank. Turn on the hot tap and double check the cold water connections to prevent any sort of leakage. Let the water run from the tap for at least three minutes to release the bubbles from the tank. Complete the venting and gas connections process.

You can also see the video below for the connections. Set the temperature according to your requirements.


To sum it all up, a 50-gallon gas water heater is far better than other water heaters. It can fulfill your basic needs like showering, washing, and cleaning. There is an extensive range of these heaters available in the market. You can buy them according to your budget and requirements.
