I've used 904/316 Class 1 liner and its up the right way. :)
Want to make sure I get it right before I connect up the back boiler.
Good idea for me to try the liner manufacturer.
Cheers
Hi,
I have just installed a flexible flue liner down to a register plate but before I connect the multi fuel boiler to it what is the correct way to seal the SS liner to my register plate adaptor?
The adaptor has double wall between which the SS liner is inserted and a large square plate...
