    primary/secondary pumping

    With regards to the primary loop. Is there any minimum length to the loop? I'm installing a system with 3 zones. 2 radiant zones and an indirect. I've read pumping away and will design the system like the picture on page 85. also the supply pipe from the back of the boiler any min. hight/lenght before the purge valve? Thanks Mike

    No

    Min or Max lenght, by the time you get all the parts in the loop for your job you will be ok. As for the purge valve make it easy on yourself and the next guy. J.Lockard
