Installation
6. Install a 1/2" 15 degree swing-check vacuum breaker at the top of the return coil header using
Note: Vacuum breakers should have extended lines from the vent ports to the atmosphere or
7. Install a "Gate" type valve in the supply branch line as close as possible to the steam main and
8. Install a "Gate" type valve in the return branch line as close as possible to the condensate return
9. Install a strainer as close as possible to the inlet of the control valve and steam trap(s).
10. Steam trap selection should be based on the maximum possible condensate flow and the
11. Install a Float-and-Thermostatic (FT) type trap to maintain proper flow. They provide gravity
