it is a w/m wtgo4 w/riello40 f5 burner.after a call for heat when the returns get warm,it shuts down and restarts within seconds{it does the purge}at first thought the thermostat and or the honeywell L8124A.but now am wondering maybe the riello?runtime 20 to40 mins if cold.by then the thermo is satisfied,house is warm and i wonder should it do that?
