    Min run?

    In primary secondary piping, is there any minimum run length for the primary loop? Or can it just go from supply to return port as long as everything fits in? I am going to install a Biasi b10-5sec boiler on an old gravity system with 2 inch supp/ret. I am also puting in a megastor40. I just wanted to know so I can get this job sized properly. I have Dan's Book "Pumping Away" (Great Book!!) but it makes no mention of any minimum run, also for those of you installing Biasi, is there anything I should watch out for that is different, from the standard boilers I have been installing?

    Thanks in advance,
    Rich

    Cool

    I missed the last one, (actually the first one ever!) in Hartford, I was recovering from hernia surgery courtesy of an arcoliner. Do you think I could use 1-1/4" for my primary loop or do I need to stay FULL port because of the 2 in mains?

    By the way, Thanks for writing all those books and Happy Birthday!
