Just had a rinnai e110crn boiler installed and the water doesn't seem to be pumping through the system. It just happens to be the coldest day of the year so far

    Was it properly bled? Are the pumps running? Valves opening?

    That is a Grundfos pump in the boiler. turn off the heat and hot water buttons on the controller, remove cover, remove that quarter size chrome screw on the head of the Grundfos and with a fine straight edge screwdriver reach in and spin the impeller. They sometimes get stuck.
