Rinnai E110C

BilljulianBilljulian Member Posts: 12
Installing this in my house. 6 zones. 2 are radiant. Question: with the low loss header as part of the provided package must I still connect my primary and secondary loops with the core tees (within 12 inches) as I would normally?

Thanks bill

    low-loss header

    replaces closely-spaced tees in most installations.  Primary is above the header, circ for that is inside the boiler on the Rinnai.  Secondary is whatever pump you select for the job and whatever piping that supplies.

    Rinnai low loss header

    Thanks for the reply I figured it replaced the closely spaced tees but was not sure. So I would pipe the system not connecting the supplys and returns whereas the LLH does this for me?

    not connecting?

    Not sure what you mean by "not connecting."

    P.19 of the installation manual clearly shows the proper configuration.

    What I mean is the LLH does the same thing as connecting the "spaced Tees" does? So I would not be connecting the spaced tees as I normally would had I not had supplied the LLH.

    LLH replaces closely spaced tees, no need for them if it is installed.
