    2 new boilers

    Old boilers were hydrotherm condensing. It was a primary loop, return from the system into a tee. The tee fed both boilers. Don’t know how it ever worked right.

    Converted it into primary/secondary per their diagram.

    New boilers are reset. Installed OAT sensor, system supply sensor, and cascaded the 2 units.

    All hydronic, gas, electrical, comm, venting done by us. We tied back into existing.

    Just need to put some hangers on the venting and gas

    Is Reset the brand?

    White handle ballvalves, did you install with handles pointing in the direction of flow? Kind of a cool idea.

    Now waiting on the insulator. Fired them up friday. Will check gas and set combustion monday. As well as making sure all the air is out.

    Ballvalves. Yes and if they were both thr same way they would hit each other
