A gas dryer can be a good alternative to electric, despite the additional cost of the appliance itself. You can venture to offset some of that extra cost by installing the new dryer yourself. Make sure that your outlet and the requirement of your gas dryer are the same before you start; then, once you have everything you’ll need, it’s time to get started.

Note: Gas leaks are very dangerous, so do not attempt a self-installation if you have no prior experience with these types of projects or if you have no safe, quick ways to test and fix a leak.

Step 1 - Turn Off the Gas and Electricity

You need to turn off the main gas supply right at the meter first. If the supply pipe has a cap, you will need a pipe wrench to remove the cap on the gas pipe where it comes out of the wall. Also, if the gas supply has been installed with the wrong size shutoff valve, you will need to use your pipe wrench to hold the pipe so it doesn’t turn while you remove the shutoff valve.

Before doing any repairs or before doing a new install, the power should always be turned off as well. Shut the power off right at the breaker box.

Step 2 - Install the Connections for a Gas Dryer

The instructions for the installation of the gas connection parts for your gas dryer should be included with your gas dryer installation kit. If you are unsure, you should always contact your gas provider. Most providers offer reasonable installation fees.

Step 3 - Inspect the Vent Hole

Check your vent hole on your gas dryer to make sure it matches the vent hole in your home. If it doesn’t you will need to cut a new dryer vent hole before proceeding

Step 4 - Clean Up

Wash and dry the floor where the gas dryer is going to sit and its immediate surroundings. Do this after you inspect the vent hole just in case a new one must be cut so that any debris can be cleaned up as well.

Step 5 - Put Pipe Dope On

Put the pipe dope on the threads; then, take your stainless steel connector and screw it to the pipe.

Step 6 - Check for Leaks

Once the dryer gas lines are hooked up, check for leaks. Mix 50 percent water with 50 percent liquid dish soap. Put the solution on the gas connections you have just installed and then turn on the gas. If you see bubbles, it means you have a leak. Tighten and test again until the leak is gone.

Step 7 - Fasten the Vent Hose

Fasten the vent housing to the duct then place your hose clamp on and tighten. Keep your vent hose to the shortest length possible to increase the efficiency of your gas dryer.

Step 8 - Finish Up

It’s time to plug your gas dryer in. Attach the lose end of the vent hose, and then push the dryer back into place. Keep it at least three inches off the wall for circulation.

Note: Some codes require gas dryers to be elevated 18 inches above the floor. Check your local codes and regulations to see if this applies to you.

Step 9 - Turn it On

Turn the gas on and the breaker back on, and test drive your new gas dryer.
