Method of Encasing Indirect Radiator with Hot Air Outlet in Wall 364 Chapter 20--Piping for Steam Heating Systems and.drips running to a wet return main. When such an arrangement as this is used for the supply connections it becomes permissible to place the valve at the radiator inlet in the conventional manner. Figs. 28 to 34, inclusive, illustrate typical approved connections to cabinet-enclosed and other non-ferrous heaters. Connections to such heaters often are troublesome. It is desirable where practicable, to place both the supply valve and the trap in the basement or at least to place them outside of the heater enclosures. It is exceedingly.important that no expansion and contraction strains from the piping shall be brought to bear against any convector, since not only damage but also annoying creaking noises may follow such strain.
