Keeping this in consideration, how do you start a pilot light on a boiler?

Manual Boiler Pilot Light Ignition

  1. Turn the gas control knob to the "off" position and set the thermostat in your house to the lowest setting.
  2. Remove the access panel to gain access to the pilot light.
  3. Peer into the access hole and look for the pilot light orifice; use a flashlight to make a positive identification.

Furthermore, why is my boiler not igniting? Burner won't ignite: This is the most common cause of a boiler failing to provide heat. If the gas jets on the burner will not ignite, no heat will warm up the water in the tank. The trouble may be due to a failed electronic igniter/pilot light, or perhaps trouble in the gas line.

Also Know, how do I start my boiler?

The Boiler Startup

  1. Check all valves and place in their startup position.
  2. Open the sight gauge and water column high- and low-water shut-off valves.
  3. Close the bottom blowdown valves, then open the upper drum vent valves.
  4. Start filling with soft water.

Is it dangerous if the pilot light goes out?

The worry here is that when a pilot goes out, the gas valve that supplies the fuel for the pilot flame could still be pumping gas. This can mean a buildup of gas, and when the pilot is relit or relights itself it could result in a very serious explosion.

Why does my pilot light go out when I release the pilot light knob?

The most likely of those is that the thermocouple needs to be replaced. The button you press to light the pilot bypasses the thermocouple. When you release the button, the thermocouple ensures that unburned gas doesn't get released by shutting off the gas when it's not heated by the burning pilot light.

How do you reset the pilot light on a boiler?

Locate the pilot light – you may need to use a torch for this. Light a match, hold it next to the pilot light tube and turn the gas control knob to 'pilot'. Press the reset switch and light the tube. You will need to hold the switch down for one minute after the flame has been ignited.

How do you troubleshoot a boiler?

No Heat or Poor Heat
  1. Thermostat – The first thing to check when boiler troubleshooting is the thermostat setting.
  2. Fuse box or circuit panel – Check the fuse box or circuit panel for a blown fuse or tripped breaker.
  3. Standing pilot – If the boiler uses a standing pilot light, check to make sure it's on.

Why won't my boiler pilot light come on?

If the pilot light on your boiler has gone out, the cause is usually debris blocking the jet. The jet for the pilot light is tiny. Even a small spec of dirt can block it, cause the pilot light to go out, and then the boiler won't re-ignite.

Should a boiler pilot light always be on?


The pilot light is the blue flame that always stays lit under your boiler. When heat is required, the pilot light will inflame that gas and send it to the burners. The pilot light must always stay on or gas will easily escape. If the pilot light keeps turning off, then your boiler is not working.

How do you light a gas furnace with electronic ignition?

The pilot light has a separate small gas line running to it with its own valve. When the furnace comes on, this valve opens, and then the electric spark ignites the pilot. A flame sensor detects that the pilot is lit, opens the valve to the burners, and the pilot light ignites the burners.

What do you do when your pilot light goes out?

What Should You Do If Your Pilot Light Goes Out?
  1. Locate the pilot light assembly, including the gas valve with “On,” “Off,” and “Pilot” settings, and pilot reset button.
  2. Rotate the valve to the “Off” position, and wait several minutes.

Why is my Baxi boiler not firing up?

Boiler failing to ignite
Common causes of a Baxi boiler locking out include overheating (110), fan fault (160), flue overheating (E131) and an issue with the printed circuit board (PCB) (E168).

Do all gas boilers have a pilot light?


With today's boilers you have no pilot lights, they are all automatic. Once a small flame is present then the gas valve releases more gas to heat up the water circulating within the boiler. With the boilers with a permanent pilot lights the only reason they went wrong was the thermal coupling.

Is it safe to relight a pilot light?

If you are trying to relight the pilot light, before turning the knob to the pilot position, wait for some time until the gas smell goes away. If you follow these instructions, it is safe to light a pilot light using gas lighter.

How do I reset my boiler?

Only press the reset button once; repeatedly pressing the button may damage the control panel, leading to an expensive repair. Hold the reset button for 3 seconds before releasing. If your boiler displays a flashing green light, it should have successfully reset.

Can you turn off a boiler?

If you have an old boiler — especially one with a continuously burning pilot light — it may well be worth turning off the boiler in the months when it's not used for heating the home. Even if you have a more modern boiler, you may want to switch it off if the water cistern is not a modern one coated with polystyrene.

Why is my heat not coming on?

Thermostat malfunctions cause most heating system failures. Other causes include a tripped circuit breaker or blown fuse, or—in the case of combustion furnaces—a pilot light that has gone out. If the heat doesn't come on even when you adjust the thermostat above room temperature: Or replace the fuse.

How does a boiler work diagram?


The boiler is the most important part of a central heating system. A valve opens, gas enters a sealed combustion chamber in the boiler through lots of small jets, and an electric ignition system sets them alight. The gas jets play onto a heat exchanger connected to a pipe carrying cold water.

How do you maintain a boiler?

How to Maintain Hot Water Heating Systems
  1. Open the valves on radiators and convectors to let out air.
  2. Close the valve.
  3. Turn off the power and water.
  4. Stick the end of a garden hose into the boiler drain cock.
  5. Open the vent valves on a radiator located on the top floor of your house.
  6. Turn on the water supply valve so fresh water will flush through the system.

What is boiler purging?

Furnace purging refers to the clearing of the entire flue gas path for any combustibles that are leftover in the furnace. This clearing function is accomplished by ambient air. This is a mandatory safety requirement before ignition of fuel and is an interlock in boiler startup.
