burnham alpine 150 boiler

paulg71170

About a month ago I had an Burnham Alpine 150 boiler installed.  From

the start it made a loud noise on ignition, that can be heard throughout

the house and even outside through the venting.  The noise goes away

after the flame is established.







The plumbing contractor has been back and done a combustion test and

everything is in line with the manufacturers settings.     I am drawing 6

inches and upon firing goes down to 5 inches.  I am not sure if I am

saying this correctly, but i believe so. 







The burham rep is being called, but the contractor believes it mat be

related to the fan.  When igniting the rpm's ramp upin the 4000 range

and as they go down the noise stops.   This repeats every time it fires.









I have been told that other alp150's they have installed have had this issue and others have not. 







Has anyone else experienced this?  Any help would be appreciated.







Thanks,







paul
