    I've looked at the piping of this Trinity and I don't see the primary loop that is required on all Trinity Boilers. I've installed over 20 of these units and a Primary looped is needed so you don't burn out the Heat exchanger.

  • @geek31 There are 3 primary loops only one will run at a time and they are all powered by a UPS 26 so the boiler gets lots of flow and the heat exchanger wont burn out. I have also installed over 20 of these boilers and serviced even more gutting one right down to the shell and rebuilding it. "I KNOW WHAT I AM TALKING ABOUT".
