Ever had the fault that the fan is just not stronge enough or the door seal is't holding tight occasionally?
The reason why I ask is I can't find a faulty component within the system as the boiler works when I test it everytime.

I had an occasion like that once and when I went outside to check the flue, ivy had grown inside the flue, It might not be ivy in your case but, some kind of interference in the venture  |

Now I did look at and in the flue from outside but nothing was out of the ordinary. I also checked the flue elbow Venturi connection points and they seemed fine and clear. The casing seal was flat so I've ordered one as that's the cheapest starting point but it's intermittently doing it so it will develop. It would be nice to know if others have a technique for pressure leakage on a positive pressure system. |

I hate them dangerous fucking things, advise the punter to replace it. Don’t you get caught out & it bites you on the bum.

So for the Daftys of this world, is a pp boiler one that by default will try to expel gas (general sense of the word) outside the casing so if there is a tiny air leak in the seal of the casing it will push the gas out. By gas I mean the air present inside the casing which presumably has a higher level of CO than usual - I obviously don't mean natural gas.
Does that mean most boiler are negative pressure so if there is a tiny leak in the seal of the casing then no big deal as it juts means a bit more of outside air gets sucked in?
Mines in the garage so I'm not bothered but just curious

Not many positive pressure boilers still going as they get the customer to change them out with scare tactics. |
