Just bought a 25 year old single story house with a burnham
boiler,.Pressure on the gage is a steady 25psi. What steps do I take to
reduce the pressure to 12 psi. (Lots of clunking noise in boiler)

Not to be critical
You actually think someone can give you the steps with out seeing the
installation?

Call a local boiler pro and have them give you an assessment.
