JG Speedfit for combi systems

[ZACCCC]

I'm doing some work on my CH system (which runs off a Duo-tec Combi HE A Range 28 model) and I'm intending to use some JG Speedfit plastic fittings (tees and elbows). The Screwfix catalogue says that these are suitable for pressurized and combi systems but I'd be interested to know if the lads on here think that's ok or not. Thanks.

Have you read the speedfit instructions?

They will be fine, just don't put them within 3 metres of the boiler on the heating flow/return pipework.

Just read them now. Got a bit lost with the stuff about putting earth wires across JGS couplings - are they needed across JGS fittings in CH flow & returns?

Thanks for that.
