I have a whirlpool cooktop ( gas ) model SCS3014GB2 wishing to convert it to (LP), and be able to use as a outside appliance using my 20/30 lb propane tank. I understand i have to change the orifice on the burners, I have those, my issue is- do i need to replace the push valve on the regulator which is on the stovetop with one for LP, the other issue connecting the lp tank to the stove top.
