I have a 3 phase steamer ( http://southbendnc.com/downloads/SBspecs/steam/EZ.pdf ) and my supply is a 3 phase high leg delta. my question is , if there is any problem feeding this steamer with the a,b,c phases or It would damage the equipment (the B phase). Im not very clear on this high leg 3 pase delta , I have seen another steamer connected to this supply without a problem , explanations please.

240/120 3PH 4W will not pose any problem to a 240V 3PH 3W load.
 
As long as the unit is rated for the supplied voltage and not under, If it is a 240 supply you could not use a 208 rated equipment. And uses no neutral you are good to go.

Most units will have a dual rating 208/240 v.
 
The so called ''stinger leg'' has no issue phase to phase. It is a phase "B" to neutal issue only.The voltage to the grounded conductor is higher on this one phase because of where in the windings of the transformer the neutral is tapped.
 
As long as the mfg didn't pull any 120V control voltage from one leg it won't matter. Any phase to phase is 240.
 
What's more, you can connect any 240v loads that do not require a neutral to any two lines, including the high leg.
