9 out 10 times the gas vale won't cure it, try increasing the minimum fan speed and if it's a plus go into the d codes and adjust the mixture.......... As for the flue joints the was a problem with the inner seal on the 45* bends
Seven, you?
Only get 5 but don't fit them find the controls a pain in the arris for my simple mind
I cannot believe the comment that Vaillant the best boiler on the market are tat. I can only assume that the person who Made this comment works for another lesser boiler manufacture .
i fit well over 100 boilers a year as williams and co will confirm and the only time I have come accross this problem was when a few years back Vaillant changed from grunfoss to another manufacturer, they very soon changed back.
also your comments don't solve the problem that the person who posted the inquiry asked, which I thought was the point of the forum. Bob Edmunds
