Culled from an Ideal install guide:

Terminal Position Minimum Spacing
1. Directly below or alongside an

ISTR building regs bumps this up to 600mm minimum nowadays.

Still 300mm last time I looked

No, in the case of this particular dimension it may not be overridden by
the manufacturer. Check the BS (instead of spouting it ;-)
