How to Light a Boiler Pilot Light

There are two forms of vaccine pilot lights. One is a manual kind you need to light, and the other one is an automated pilot ignition kind that lights itself. Before lighting any boiler, you have to know which kind you’ve; there are two ways to determine this. An automated ignition kind will have a security tag on the front of the thermostat which tells you it is a automatic ignition system. If there is not any label, examine the peak of the gas control knob. If the control knob has two settings, off and on, it is a automatic ignition system. A manual ignition will have three settings on, pilot and off. Never try to light an automatic ignition system manually.

Manual Boiler Pilot Light Ignition

Turn the gas control knob to the “off” position and set the thermostat at your home to the lowest setting. The gas control knob box will be gray and situated close to the floor at the front of the boiler. The knob will be situated on top. If you smell any gas, allow the odor to dissipate for a quarter hour. Open windows to ease ventilation.

Remove the access panel to gain access to the pilot light. In most cases, this panel is situated adjacent to the gas controller box. It might be attached using finger screws which are turned out, or it might be held on using gravity clips so the panel can be lifted away.

Peer into the access hole and search for the pilot light orifice; use a torch to make a positive id. The pilot light orifice will appear much like an upturned piece of steel tubing — the pilot light burns at the tip of this tubing.

Turn the gas control knob to the “pilot” position, then press down on the knob. Pressing down on the knob will release gas to the pilot light orifice.

Insert a lit fireplace match or a butane candle lighter to the access hole and light the pilot light. Keep holding down the controller button as you do this. After the flame from the match or candle lighter reaches the pilot light, a blue flame will suddenly look. When you find the blue flame, then remove the game or the candle lighter. The blue flame will remain lit.

Keep the pilot light button pressed for the next 30 to 45 seconds. This action will open up the thermocoupling at the end of the pilot light orifice tube that is inside of the gas controller box. Release the button after the designated period and the pilot light should remain burning. If it goes out, repeat the lighting process, but hold down the pilot light button for a full minute. If the pilot light still goes out after this time, the thermocouple has to be replaced.

Automatic Boiler Pilot Light Ignition

Turn off the electrical switch which controls the boiler. Either there will be an electrical box having an on/off switch on the boiler itself, or you’ll need to find the breaker switch on the breaker panel and flip it to the “off” place.

Remove the access panel either by turning finger screws or lifting it up and pulling it off, if it is held on by clips.

Turn the gas control knob to the “off” place. If you smell gas, then allow the gas odor to dissipate for at least 15 minutes. Open windows to ease ventilation.

Turn the gas control knob to the “on” position when the room was sufficiently vented and there is no more gas odor.

Flip the electrical switch or the condom into the “on” position. You will immediately start to hear a “clicking” noise from the access hole where the panel was eliminated. This is the automatic starter which will light the pilot. If the clicking noise does not abate after 30 seconds, or even the snapping noise stops but there still is no pilot light, there is a issue and a service technician has to be called.
