How to Turn On a Wall Heater (New Step-By-Step Guide)

If you own a wall-mounted heater, you should know how to turn it on. You may be wondering, what’s the big deal in turning on a heater? Electric heaters are easy to turn on, but for gas heaters, you will have to follow more steps.

This article will give you a step by step guide to safely turn on the heater in your apartment.

Step 1: Locate the Pilot Light

In some heaters, it is easy to locate the pilot light, as it is just behind the heater vent. For others, you will have to open the cover of the burner area or remove it altogether, then follow the gas connection from the main gas supply to the pilot light.

The pilot light is inside the heater, behind a metal plate. You may need a torch to find it.

Step 2: Ignition Process

Now, locate the dial on your heater. For new wall heaters, turn the dial towards ‘Pilot’ and press down on the ‘Ignite’ button. You will have to press the button, again and again, until the pilot light starts from the spark.

When the pilot light starts, continue holding the button for about a minute. Then, release it.

After that, turn the dial to ‘ON’, which should ignite the main burner. You will hear the sound of the burnet lighting up. Finally, re-cover the opening of the heater.

Gas Heaters

For old wall heaters, after turning the dial towards ‘Pilot’, hold down on the pilot gas button, instead of the ignite button. After about 30 seconds, release the button.

Then, press the button again to light up the pilot. The new wall heaters ignite the pilot light with a spark. However, the old wall heaters need to be lit up manually by a match stick or a long reach lighter. After the pilot light starts, keep the button pressed for about a minute. Then, release it. Now, turn the dial to ‘ON’ to start the main burner.

Note: In case the main burner doesn’t ignite, repeat the steps from the beginning.

Step 3: Set the temperature

Once your heater is turned on, set the heater on your desired temperature using the electric thermostat. Some heaters have a temperature dial, while others have digital displays with buttons to set the temperature.

The thermostat usually keeps the temperature one degree above or below your set temperature. It is recommended to keep the temperature in the range of 70° to 78° Fahrenheit.

Safety precaution

If you own a wall heater, you probably own a thermocouple too. It is a device that works with the pilot light to keep it lit.

The thermocouple runs from the pilot to the main gas supply. When the pilot is on, the end of the thermocouple near the pilot heats up and sends electric voltage to the main gas valve. This voltage keeps the gas supply open. In case the pilot light goes out, the voltage supply stops, closing the main gas valve.

Final thoughts

The wall-mounted heaters are becoming increasingly popular in houses as a better heating solution. These heaters are easy to install. Plus, it is fairly simple to turn on a heater if you follow the steps in the correct order.
