yes you can go ahead with the orignal suggestion or you can switch over to all pex piping. pex is just as cheap as copper but a much better product..will last much longer and very easy to work with..all you need is to rent or buy a crimper tool for pex..no solding.....handyman
i agree with glennjamies reply & also speedy peteys of having a2-pole 30 breaker but i would imagine that there was already a 2-pole 30 or 40-amp breaker installed for the stove...hope this helps......handyman
