Lighting Your Pilot Light

Posted by on February 3, 2014

Most modern gas-burning appliances have switched over to hot surface or electronic ignition; there are still a lot of standing pilot systems manufactured and being used. If your house has a standing pilot type system, you should know how to check and light your pilot without calling a plumber.

The following steps will explain how to light your pilot light, what to look for when doing so and a few different methods you can use to get the fire burning well.

How To Light a Sealed Combustion Pilot

Using a sealed combustion chamber, it is not necessary to, nor should you, access the burner assembly. Everything that is required to light this pilot is mounted to the of right the burner control module and there is a looking glass in the access panel that you can use to visually verify ignition. This access is bolted shut on purpose and should only be accessed by a licensed and professional plumber.

  1. Turn on the gas control on top to the “pilot” position.
  2. Simultaneously, press and hold down the control knob itself to allow gas to flow into the system.
  3. Hold down the electronic spark button, which is located on or mounted to your control module until you hear it click. You may need to click the button a few times before the pilot is lit on. Be aware there may be a bit of air in the line and it will take a few seconds to “bleed” out.
  4. Take a look to confirm ignition has occurred and keep holding down the knob for approximately 30-45 seconds so that the pilot can heat up the thermocouple enough to confirm ignition to the thermostat in the control module. If the thermocouple doesn’t heat up enough, the pilot will stop burning and fade out.
  5. Let go of the control knob altogether. Have a look to confirm that the pilot has continued to stay lit.
  6. Switch the gas control knob to the “on” position on the unit. If the pilot was out long enough for the water temperature to drop, the burners should kick on within just a seconds. If the hot water has not cooled down, there may be no call for the burners to come on, therefore don’t be surprised if it doesn’t fire up right away.
