CorgiC - My girlfriend was 1st (I think) qualified female gas fitter (laura) in uk (many years ago) and a few friends have been (still are) doing it. Very few are able to decipher what goes on in modern boilers. I have a bit of advantage in knowing what a 'boot sequence' is, how it works, and...

Sorry. Ok accepted. I appreciate the candid reply. Knowing what I do and the gas advisors I have I'm happy to leave it at that. I don't think you'll b reading about me in the papers. I certainly appreciate safety concerns but in this particular case I feel ok. I will replace the microswitch...

Corgi crouch please reread the last post I made and just give me an answer - what can b wrong with this and I'll b happy 2 let it go!

No disrespect to anyone. I have professional advice saying I don't have a problem with this temporary solution (hey I'll get another microswitch and get it sorted). Why is it that no-one is able so far to tell me what the problem with it is !! What danger? These things are failsafed to an...

Please understand I am not asking for justification for this fix or anything like it. I need to know what is WRONG with it and potential problems with it! I have absolutely no interest in justifying it. I want to know what harm it could do. If anyone is able to tell me then please do - then I'll...

Ok bengasman. Sorry to have troubled you. Perhaps someone else will be able to explain why this bypass is dangerous. That is all I need to get it fixed. Thanks. Dave.

bengasman, would you please just explain what the issue is. I will pass it on and sort it out! Just blindly saying it is dangerous does not help. Tell me what the issue is! You are not being helpful. I am asking you to help me! Not just make comments without explanation. Regards, Dave.

I guess I should also mention that the heating is totally off when I am not here. As I say I am not a risk taker. I understand that a leaf getting past the intake guard could cause trouble, but I always check, and the other safety devices should take care of that as well - or tell me I'm wrong...

Reason given for the APS bypass is like this ; It is there to prove air flow to the boiler (in this system a bi-directional flow to make sure that it flows in both directions) which is determined by a differential pressure between the two venturi feeds. If one or other is blocked, or the...

Thanks for that Tony. I appreciate that you may be better than the (three) engineers who came out (referred by halstead). The advice regarding the air proving switch was from these forums as a 'temporary' measure to find the fault. Advice from an ARGI engineer who replaced the pump...

Problem was due to two things. First was pump giving up slowly which reduced water flow and increased temperature. It was the pump itsself that was cutting out or seizing due to the temperature therefore switching the primary flow switch off when it stopped. It takes a long time to 'reset'. I...

I've had the above boiler 10 years fine but now giving me real trouble. I have searched everywhere for similar problems (but similar is not the same) and have followed advice i've found. CH runs for expected time and switches off for a while, then fan (not burner) turns on and safety lockout...
