Steps to Light Your Furnace Without a Pilot Light

Here’s a step-by-step guide to efficiently light your furnace if it’s equipped with an electronic ignition system:

4. Watch for Ignition

After pressing the ignition button, you should see a flame or hear the sound of the furnace firing up. The ignition process typically only takes a few seconds.
