we recently  had an aquatherm  340 ss  installed  the system  hold  good pressur  at 12 lbs   hot water is constant  180

the system is air  bound  we have an expansion tank at the wood boiler  it  feed into our  existing  hot water   system  a weil mcclain unit  with  the old  style  expansion  tank

we have  bled  the  system  three  time  but the  air  seems  to enter the system  when  we  iopen the  lines  from the wood boiler  we are running 1.25 inch pex   triple wrapped   both sides  hold  good  pressure   how  can we get rid of this  air? any help would  be appreciated

"""" but the  air  seems  to enter the system  when  we  iopen the  lines  from the wood boiler""""""  ...open the lines and bleed both of the boilers and pump some more juice in it.
