This is one I looked at a month ago a block north of Glover Park in DC. It is an old Burnham Series 4 that is about 25 years old. It is connected to a two-pipe system with cast iron radiators and steam traps in a 1920's vintage rowhouse.
Most of the traps were original. The client complained of knocking and water hammer in addition to high fuel bills and reliability issues.
