The inner flue on my Potterton Prima 40F has corroded, resulting in frequent sparking to relight.
I have a replacement flue kit (the full kit rather the ‘fix’ kit). My question is how should the inner flue be sealed against the fan housing output pipe. The Potterton Manual indicate a push fit; although this one seems a little loose to rely just on a push fit ~ also when removing the old inner flue pipe there appeared to be some form of sealing compound ~ what do you recommend to make this seal?
Cheers.
Ps. It's a rear exit flue.
