Unusual sound on a Burnham ESC

0409004090 Member Posts: 142
Been pleased with a Burnham ESC4 but have a concern about a new sound this year. 

It's almost exactly like the sound a metal dryer outside vent flap  makes in just the right wind conditions, a merge between a clap and a metallic thud. 

It happens twice in a cycle, the first originates about 30 seconds after the boiler ignites and again when it shuts off.  A single "clap" each time, twice per cycle.  It's central to the unit -- I can't pinpoint any location it's coming from as it just seems to suddenly resonate.

Any known conditions that would create that sound?
