How to Light a Furnace Pilot Light
Here, we will explain the basic steps for re-lighting the pilot light of a gas furnace.
1: At First, Locate the Instructions Label on Your Furnace
Every furnace has a label on it that tells you how to light a furnace. However, sometimes the furnace area may be dark, or the printing may be small. In these cases, it may be difficult to read the label. Keep the following instructions near your furnace or in another safe spot where they can be located easily to make the task much more manageable.
2: Next, Find the Pilot Light and Components
Near the bottom of your furnace is a switch that usually says “Pilot,” “On” and “Off.” When you find this switch, turn it to the “Off” position. Then wait at least five minutes. This is important because it gives some time to the gas to dissipate. This step is necessary to avoid the possibility of starting a fire.
3: Finally, Re-Light the Pilot Light
Once the gas dissipates, turn the knob to “Pilot.” Then, hold down the “Reset” button, bringing the flame of a long lighter close to the pilot light opening. This should light the furnace pilot light. Once you are sure that the pilot light is on, release your pressure on the reset button.
Final Thoughts
Lighting the gas furnace pilot light is not needed very often, but is a useful skill you want to have in case it is required. As long as you keep on following the steps on how to light a furnace, you should have no problem, and your room will be warm and cozy.
