boiler wires

Postby redkev » Wed Dec 09, 2009 10:11 pm

i have just had my boiler changed from a system boiler to a combi.

i previously had a seperate timeclock for the boiler and now i have an internal cock. so i have 2 cables, with me having an internal clock now do i only need the 1 wire as i presume one went to the external clock?

Simply Build It

The cable from the spur with 3 amp fuse should go to the boiler. The integral timer does the rest, you may need to fit a link if there's no room stat fitted.

The original set up would have been from the spur to the timer, then to the boiler/pump etc etc etc
