Relay vibrates off

The PB gas boiler manual says my DE-03-SV-WPC boiler should have a Honeywell R4222A1001 relay. The original went bad, so my plumber replaced it with a ZC90340 relay which vibrates loose over time, in spite of his efforts to tie it in place. When it gets too loose, the boiler won't shut off until I push it back into position. The poor man has since died, so I obviously can't call him back. Did he use the wrong replacement part? If so, what part do I need? It looks simple enough to just swap in a new one. I looked up the part number on the internet, and found the R4222A1001 was replaced with R4222B1082, but pictures of that relay show 4 prongs on the side where mine appears to only have 3 slots.

That happens. There is a wire that hooks into the base and goes around the relay and holds it in the socket. You can make your own wire. No you didn't get the wrong relay.

I'd just loosen the plate and get a zip tie behind it and wrap a zip tie (or a couple strung together) around it and tighten the screws back down.
