These are pictures of a Dunham system return trap and associated near boiler piping. Also shown are a Dunham thermostatic radiator trap & supply valve as well as end of line vent/trap. Missing are the other components which were scraped long ago such as the damper regulator and linkage assemblies to operate flue and draft. This system was installed approximately 1921 in a 4500 sq. ft. home in Essex Co. New Jersey.
