take a voltage mesurment between the two hot of these recepticals if you get 0 volts then use a connuity tester that will work on line voltage.like a ideal volt-con type meter and see if you have conniuty between them or 240 vac. but if you get 240 you cant tie them together but you could step it down to 110 with a transformer. most of the smaller generators use only one set of windings for 110vac while the ones that have 240 vac recpticals on them center tap between two windings. but test it first! also turn off one of the breakers and it should show open between the two hots with out the gen. running remeber that if it has any auto throtole control it will be tied to one of the breakers and give you a false connituty reading. I'll see if there is a wiring diagram avalable and e-mail it to you if thats ok?
