Hi all We have a green house that's heated with a Wiel McClain 97+ It's cold and windy here in the Berkshires and the boiler should be making high fire. It's got a target of 190 but a supply of about 100. No errors. It's bouncing on and off with a firing time of well under a minute. Anything I should be looking for? It's running 1 1/4 fin tube perimeter single zone with dom water. Thank you for any insight.
