Just joined the forum hope I can help contribute. I'm currently doing my CCN1 Core Domestic Gas Safety. Nearly got my 50 days for my portfolio, just passed my theory and I'm currently doing my practical. Just failed my install and commission on a Robinson Willey Fire Charm LFE. Reading through my procedures and referencing the book so was wondering if anyone knows of any online software I can get that will help. Currently suffering mind block, Any help is greatly appreciated :cool3::cool3:
