Weil McClain Boiler Question
I have a GV-5 series 1 WM Gold boiler that is connected to a WM Combo 30 indirect. The water stops circulating to my baseboards when the boiler is supplying hot water to the combo 30 . There is a 3 way valve coming from the boiler supply diverting flow from the riser going to the base board feeds to the combo 30. I have 4 zones and during the past few weeks could not figure out why the baseboards are cold even though the room stats are calling for heat. I have 4 Taco circulating pumps and 4 Honeywell zone valves. I have a temp. setting of 160 cut in to 190 cut out on the WM boiler. I raised the DHW temp this winter to allow hot water to reach our shower located at the other end of our rancher. This causes the indirect to take longer to reach HW temp. causing the base boards to not get flow. I've read various discussions on close space t's configurations but would like to see a diagram of how that piping would be run.
