Accordingly, how do I turn on my gas fireplace?Turn the knob from the “Off” to the “Pilot” position. Push in the pilot knob, which manually sends gas into the system. Push the igniter button once every second until it lights. Depending on how long it’s been since the gas fireplace was last used, ignition may take multiple attempts.Beside above, should the pilot light always be on in a gas fireplace? Electronic ignition is when the pilot light on a gas fireplace/insert/stove is only running when the fireplace is on, this means that the unit is likely to have a battery backup as well. A standing pilot is always on, always using a small amount of gas to run constantly unless the gas is physically turned off. Subsequently, question is, why is my gas fireplace not turning on? 1. Pilot light systems are the most common reason gas fireplaces fail to light, so check the main gas valve to make sure the gas is turned on. If gas is coming out of the pilot, but it still won’t light, the spark igniter could be the problem. Look for and clear out any debris between the igniter and thermocouple.How do I know if my gas fireplace is working? You should: Inspect the glass doors for cracks or latch issues. Check that gas logs are in the proper position. Turn gas off at the shut-off valve and test the igniter. Ignite the fire and look for clogged burner holes. If present, turn off gas and clear obstructions with a pin or needle.
