Rinnai q130 boiler

Got a q130 boiler that won't fire. Boiler tech told me it may need an outside reset. My understanding is that these units fire once it senses flow. I have a 3 zone hydronic system with 3 brand new taco IFC circulators with a 4 zone taco relay. WHAT the hell could be wrong? Any1 got advice your help is appreciated

  • Proper selection

    Is this a domestic water heater being used for hot water heating?

    If it is, keep it feeding your hot water needs, and get a boiler.--NBC

    Not a tankless

    It's an Atag boiler imported from UK and labeled Rinnai.



    Sorry too much to diagnose to give you an easy answer, no magic button to push on this one.

    Pre-purge

    Does the unit run through the pre-purge cycle? It is 17 min on start-up!

    Problem solved! You gotta run t stat wire from "xx" on the relay to 22 and 23 on the boiler. Unit fired right up!

    You never said it was a new install

    More than once an installer expected products from different manufacturers to magically wirelessly talk to each other.



    If you didn't know they can't it must be a DIY install, hope other things go as well for you.
