the 38/50 space savers have 4 wing nuts /hex head nuts + washers behind the boiler back panel. be careful you donot drop then when removing off studs do bottom ones first ,hardest to remove should be able to see top ones if not in a cupboard after all 4 removed
pull out cover straight forward. When replacing tighten nuts hand tight then tighten diagonally a little at a time so each nut is tightened equally this will make for a good seal all round the cover PS check seal is okay when exposed round black rubber/neoprene in groove around boiler donot try to remove if not damaged.
