In August of 2007 our six-unit apartment building installed a Burnham V9A
series boiler (oil burning). The warranty was for one year.

When we had our spring inspection-servicing recently, we discovered that the
three-inch round glass lens on the rear, which the service manual calls the
Rear Observation Port Cover, was broken -- undoubtedly from the heat.

Our local service company says this part will cost $215 -- an astounding
amount for a small piece of glass.

My question is, do we really need this thing replaced?


If its allowing gasses to leak out, yes.

You may be able to replace it with a metal cover.
