Hey guys I have been reading on this site again the spam was crazy awhile back.  So my house is about 1800 square feet  1 and a half story old 1852 farm house.  I think I'm going to set my boiler about 25 feet away from house.  I bought some 5 wrap from the Ridgewood dealer.  So 1 inch pex from the boiler to the house, I will transfer to pex once in the house and I have about a 50 foot run to my furnace. My plenum will need a 18 x 18 exchanger I would also like to get a 20 plate maybe.  Do I need oxygen barrier pex?  I plan to use 1 inch pex in the house for as much as can I guess.  Another question on the back of the odb  does any one run any shut off valves?  Ball valves  or gate valves?  Any unions before you connect your lines?  I will keep reading older posts as well thanks.

My stove came with ball valves on all 4 ports on the back of the stove.  I like that.  Unions aren't a bad idea either for the back of your stove and each port on your exchangers.  Ball valves at each port is a good idea too for ease of removal to clean out lime or other buildup.  It's not very often you'll have to do that, but you'll like it when it comes time for that.  You do not need oxygen barrier pex.

Thanks for that. It makes me feel better about not over doing things, because I am going to go crazy on shut offs and unions!  I might not use them ever but yes I will be glad I made it easier for servicing when needed.

Oxygen barrier should not be required on lines from an open boiler/system; but good question 

Also, ball valves are not a bad idea on back of boiler.  Makes it easier if you need to blow out, or trouble shoot.
   Just remember, Rule #1 of trouble shooting, open all valves, then see if everything works (don't ask me how I know  )
