Hi Does anyone know of a tool to remove automatic air vents from ideal isars?
 
Just make sure you dump the pressure, not just whip it out like I did on a bad day once. Got soaked, not a good day, never again though :)
 
Come on gas man the PCB will fail then the spark generator then the diverter then pump and that's a good few wages for the bloke who is repairing it.
Sometimes it's better to have some wages instead of an axe lol
 
That's good then you have your preferred boiler installed / not a bad boiler the gold but for the same money I do prefer the Logic

told him i could repair it but he has just moved out of a house where i fitted a performa 8 years ago and its never played up so he has done a google on ideal,been put off and wants a gold back did ask me to fit another performa but i declined
 
Hi thanks for all the quick replies. I am thinking of making a tool to remove these air vents without stripping half the boiler down and was wondering if such a tool was available and what the interest it may be to other engineers. It would of course be usable on other boilers that use the same caleffi type air vent. I think I remember struggling on a potterton puma once due to space restrictions.
 
Tried a strap wrench but still had to remove fan, burner and flue manifold to get space and even then it wasn't easy. I am trying to come up with a solution for making this job easier and less time consuming (also with increased chance of keeping your hands from melting on the burner).
 
I've got one of these to do, after having a look at the boiler and the manual, its not going to be easy. You have to take the flue turret out and the rest of the flue manifold according to the instructions. I've got one of these that I'm going to try, hopefully it'll work, but I still don't think there's going to be enough space. If it does, it'll be a massive time saver.

I've done them with 14" grips

No removal of flue, just take fan out. Leave the large plug in the hex and only remove the aav. It just unscrews from the large round plug

Oh, so it is possible, I'll give it a try with grips like you, hopefully it'll work. Thanks for the tip.

Fan and burners got to come out anyway for the service. Its just the flue that I don't want to disturb if I can help it.

like simon said, you dont have to touch the flue, if you take the burner out you should realy change the burner gasket, also look at the obvious, you probably know anyway but look for worn probes and dodgey insulation pannels as they are known for that,

Yeah, I've got a gasket set for the boiler, which I was going to change if needed.
I've also got some Ionisation probes to change if they are the old type or in bad condition.
I'll be sure to make sure everything is OK because as we know these aren't the most reliable boilers.

Thanks for the replies on how you all carry out this awkward job. Pump pliers/boa strap wrench seems to be the only way to do the job, without removal of the flue manifold being necessary.
 
I've completed the job.

I used the boa strap wrench to take the air vent off after removing the fan and burner, this worked well. But when replacing the air vent, the strap wrench wouldn't work due to the shape of it. I ended up using grips as suggested to tighten it on.

Thanks for the tips guys.
