Solder connection only - Baxi Solo 24HE

[Megaflo-Experts]

Just moved a Solo regular boiler, and the instruction manual states the flow and return tails to the boiler must be SOLDERED, and compression fittings must not be used. Not a problem, but seems odd!
Can anyone explain if there's any technical reason why?

Because the compression couplings make the casing a nightmare to get back on. Cack boilers. Hope you didn't have a vertical flue to fit on it, big pain in the rear!

Thanks AP - That makes sense.

This has a horizontal flue out the back, but now needs the plume kit. Not cheap, as it has a replacement horizontal flue as well.

The flow and returns will now come from below, which is a little more hassle as the fitings assumed they're coming from above!
