What is ignition failure in boiler?
What does ignition lockout mean on a boiler? This means that the boiler has turned itself off because of an issue, such as low water pressure, no gas supply or a lack of electricity. You’ll generally be able to decipher the problem as the boiler should show a fault code on the screen.
Can you manually ignite a boiler?
There are two types of boiler pilot lights. One is a manual type that you must light, and the other is an automatic pilot ignition type that lights itself. If the control knob has two settings, on and off, it is an automatic ignition system. A manual ignition will have three settings — on, off and pilot.

What are the common causes of burner ignition failure or flame failure?
The flame failure trip in a typical boiler can be due to one of the following reasons: loss of ignition; fuel valve closed, unstable flame, low airflow, very high furnace pressure, dirty flame sensor and loss of electrical supply.
How do you clean a pilot light on a boiler?

What causes boiler delayed ignition?
Delayed ignition is caused by moisture building up in the furnace over a period of inactivity. The moisture begins to corrode the firebox which blocks the ports that feed gas into the burners. Hence, the loud bang you hear of the excess gas that builds up when the burners finally ignite.
Why is my gas boiler not igniting?
Some boilers won’t ignite if the gas or water pressure is too low. Low gas pressure could be a problem with supply in the area and you may need to call out the supplier to check. Alternatively, it may be that the water pressure is too low in a sealed system boiler.
