I am going to pick up my New-to-me KA-6 within the next week. Installing it will be my summer project. What tips can you help me with to make my system better? I will be completing the install my self. My current thoughts are around building a "manifold" for the return and supply, I think I want to use black Iron from the boiler to my "manifolds" the reason for this is the rigidity that the iron will give. from the Iron I will install a ball valve then a circulator flange, from the opposite side of the circulator will be a second ball valve then copper throughout the system. Also, what should I do for air elimination? What are the befits of air separators vs. air eliminators vs. Air scoops? what do I NEED? I noticed that in some of the pictures from the post your boiler thread http://nepacrossroads.com/about19903.html
some of you have air separators on every zone! I this necessary?
Some notes on the system.
Keystoker KA-6 heating 1500 Sqfq. (yes, I know it's "over kill" but I will be adding more load in the future that the KAA-4 is not rated to handle.)
The KA-6 will be a "stand alone" unit. My current oil boiler is junk.
I will ultimately have 4 zones, Main house, Addition, Garage, and basement. at time of Install there will be only 2 zones, The main house and the addition.
I'm sure I will think of more, but for now that all...
