service entrance ground lug, etc. must be bonded to the same facility grounding electrode system.
Vessel – designed and fabricated to comply with ASME Section IV, with “H” Stamp and National Board of
Boiler and Pressure Vessel Registration, with a maximum working pressure of either 30 psi or 125 psi (design
pressure specified when placing order).
Heating elements – removable, low-watt density, Incoloy sheathed, top vessel plate screw-in element. Access
is made easy via top split enclosure top cover.
Piping – 3” NPT top supply, 3” NPT left side return, 3” left side inspection plug, 1” left side bottom drain, 1”
top vessel location for pressure relief and/or air relief. All system piping and pumps must be large enough to
meet the required GPM flow shown on the Specification Table for the vessel size.
