Gas Dryers and Washing Machines [RE-wrenches]

Hi Holt,

Thanks for the heads up.  I would of course check with each unit, but the ones
that I have worked on have listed that the only change is the jet/orifice.  Yes
you are right that there is a difference in pressure etc.  But do you have any
idea of how these other companies do the converson without changing anything but
the orifice?

Thanks
