How to Install a Gas Water Heater
Step 1: Choose the right gas water heater for your home
The first step in installing a gas water heater is choosing the right type and size for your home. Gas water heaters come in different sizes and capacities, so you need to choose one that can meet your household’s hot water needs.
You should also consider the type of gas water heater that will best suit your home’s needs. There are two types of gas water heaters: tankless and tank-style. Tankless water heaters heat water on demand, while tank-style water heaters store hot water in a tank.
Step 2: Turn off the gas and water supply
Before beginning any plumbing work, you must turn off the gas and water supply. Locate the gas and water shut-off valves and turn them off. If you are unsure where these valves are located, consult your home’s blueprints or contact a plumber.
Step 3: Drain the tank
Next, drain the old water heater tank. You can do this by connecting a garden hose to the drain valve at the bottom of the tank and leading it outside or to a drain. Turn on a hot water tap in your home to allow air into the tank and allow it to drain completely.
Step 4: Remove the old water heater
Once the tank is empty, disconnect the old water heater and remove it. You may need to use a pipe wrench to loosen the fittings. Make sure you have a helper to assist you in removing the old water heater, as these appliances can be heavy and difficult to maneuver.
Step 5: Install the new water heater
Position the new water heater in place and ensure that it is level. Next, connect the water supply lines to the hot and cold water fittings on the top of the heater. Use plumbers’ tape to ensure a watertight seal.
Connect the gas supply line to the gas inlet on the water heater. Make sure you use a gas leak detector solution to check for any leaks.
Step 6: Vent the water heater
Most gas water heaters require proper ventilation to prevent carbon monoxide from building up inside your home. Check your local building codes to determine the required venting for your particular heater and install the appropriate venting.
Step 7: Turn on the gas and water supply
Once everything is in place and properly connected, turn on the gas and water supply. Check for any leaks using gas leak detector solution.
