One thing I really don't understand is why my boiler came with a standard three-prong plug for its main electrical hookup. You've got a fairly substantial machine weighing about a ton that's going to be thoroughly plumbed into place and attached to a chimney, and you ship it with a standard wall plug? I thought maybe this was strictly a European thing (or perhaps more specifically, a Polish thing), but then I think Joe Brown mentioned that Greenwoods come the same way. I believe they're made in Canada. How about the BioMax, Rob? Needless to say, I wired everything up with BX and steel conduit, but I'm wondering if anyone knows what's up with the plug.
