  Anchorage of Appliances

  • Fixed appliances are fastened down; in SDC D0 to D2 (and townhouses in SDC C) water heaters and thermal storage units are strapped against earthquake movement per R301.2.2.10.

  Local review: San Antonio is normally Seismic Design Category A or B, so this section doesn't require seismic strapping there; check whether the city's plumbing amendments or the water heater instructions call for it anyway.
