glow worm ultimate

Hi all Recently moved house, new place has a recently fitted (last year) Glow Worm Ultimate2 35c boiler. it's lovely. I'm trying to find the installation manual for this, however according to glow worms website, it doesn't seem to exist. Anyone got any ideas? I've emailed glow-worm...

Hi I have a glow warm ultimate boiler that keeps making a loud banging noise like it's trying to reignite even though it's ignited. Any ideas why please? Thank you
