Worcester Condensing Boiler - if its not firing during this freeze ?

Not a question - just a bit of advice - if its not firing up check that the condensate pipe not frozen up if its mounted on the outside of household or area subject to v low temp - look for plastic pipe exiting and discharging to gulley / - i borrowed a hairdryer to get things going / hit the pipe a 100 times to break ice within pipe -I then decided to remove as pipe v long and almost horizontal - in the manual it will advise hot water / wrap around pipe - therefore choose ur own method for thawing out / i put hot water tap on to get burner firing up and when u start to see a trickle u know ur getting on the way/ - i couldnt get the ch working but working on it as diff prob
