Burnham boiler-Beckett Stuff
Help. My 7 year old, chimney vented Burnham boiler with Beckett ewuipment is acting odd. When its cold outside, more dense air I suspect, it baffles and has repeated flame outs with the chimney attached. Take the chimney off...and it runs...but gives thayt ole "woof,woof" sound. Its got new fuel filters, new Delavan. 50x70° nozzle, new electrodes, clean air tube.its burning #2 diesel. Air wheel is at 2.5 and Suntec B2ya-8916 pump is putting out 140psi with a slight squeal. (Perhaps the squeal is cavatation and minute air bubbles due to a bad seal?) The are no obvious fuel leaks. Its got no intake piping as it used the ambient air from the garage? Any thoughts asto what is going on?
