Quietside Condensing Dual purpose
I have a slight rumbling on the 120DPW Quiestside condensing boiler. When the flame ignites. Maybe a slight delay in the ignition I don't know. Im a Rinnai guy. We got heat /HW but this rumble slightly shakes the unit for 1/2 second. Tech says not unsafe. Anybody have any ideas?
