A propane wall heater is a great way to add low cost heating to any room. When installed correctly they are safe to use, and can be more economical than electric heaters. In the event of a power outage some models can be used without using an electric ignition, meaning you won't be without heat. Installing these units won't require a professional, just a little time and a few tools.

Step 1 - Determine the Location

Your heater needs to be hung in an area where the propane tank can be placed outside the home with the heater directly on the other side. This means you will need to find a location on an outside wall. Mark the spot where the heater will be placed inside, and make sure there will be no obstructions outside in the same location.

Step 2 - Prepare and Drill

Use a drill bit to start the holes in the wall that will hold the mounting brackets. Install the brackets using the provided hardware. You will want to place the heater on the brackets to check for level, and to determine how it will hang. You also need to mark the area where the hose for the propane tank will go. Slide the heater back off the brackets and place to the side.

Step 3 - Prepare for the Hose

Use the two-inch cutting bit to make a hole where you previously marked for the hose. Run the length of hose through once the hole has been drilled to ensure a proper fit.

Step 4 - Replace the Heater

You can now put the heater on the brackets again. This time you will secure it well since this is the final step for the interior portion of the installation. If you removed the propane hose after checking the fit earlier, you can just slide it back through now.

Step 5 - Connect to the Propane Tank

You will need to go outdoors for this part. Connect the hose to the propane tank, using the adapters that came with the heater. Some heaters won't include the adapters. If this is the case, write down the type of heater and the size of the tank so you can purchase one. These can be found at any hardware store. Once the hose is connected you can test the unit.

Step 6 - Test the Heater

Turn on the propane outside. Go back in to the heater, and depress the ignition switch. You may have to do this several times to prime the heater before it actually lights. You will see the flame form, and you can start to test the different settings on the heater. Once you know it's working, you can turn it off and wait until you need it.
