In this video we’re looking at how to remove boiler components correctly, specifically the air gas unit and checking the burner seal and burner. This is something you would do on a routine service.

How to Remove a Burner From a Boiler

Welcome back to the viva training centre in Halifax, today we are going to be looking at removing and checking certain components like removing the air gas unit and checking the burner seal in the burner which is something that you would do on a routine service if it needed to be stripped out and cleaned.

We have carried out safe isolation and (tb118 your gas safe technical bulletin).

On this particular boiler we’ve got a silencer which is attached onto the fan so we need to remove that silencer which is held in by one self-tapping screw and the silencer eases off the end of the fan. Remove the ht lead from the electrode and then the earth connection.

Because the burner module is connected onto the fan we also need to remove the mains plug on the fan. Remove the earth lead and then the low voltage plug which has now removed the electrics from the fan. The next stage is disconnecting the fan from the gas valve. There are two alternatives one we’ve got a little clip which we can pop out and then pull the flexi tube away from it while the other one we can disconnect the nut on the top of the gas valve.

My preference is unplugging the little clip, then I can now ease that tube out and bend it slightly out the way. Remove the four 10 millimeter nuts with a 10mm socket driver because it’s easier (you could use a spanner).

Remove the air gas unit and check the burner seal, remember not to touch the burner with bare fingers, all you need to do is clean it off with a soft bristled brush.

Inspect the seal to make sure it’s not showing any signs of distress it’s not starting to show any signs of wear normally on these black seals what you’ll find is if they start showing signs of distress they start to go grey which is caused by excessive heat. A quick test you can do is turn it upside down and give it a tap, if the seal stay in, you know its okay.

Now we can clean out the combustion chamber if we needed to which we will look at in a future video.
