Valve Locations-All control, auxiliary, and inspector's test valves shall not be ❑ ❑ ❑ <br /> located more than seven feet above finish floor or grade. <br /> 17. Protection Against Freezing-A wet pipe system shall be used where piping is ❑ ❑ ❑ <br /> installed in areas that can be maintained reliably above 407 (4°C). Piping in areas <br /> that cannot be maintained reliably above 40°F (4°C) shall be protected by use of <br /> one of the following methods: <br /> • Antifreeze system using a listed antifreeze solution in accordance with <br /> NFPA 13 <br /> • Dry pipe system <br /> • Pre-action system <br /> • Listed dry pendent, dry upright, or dry sidewall sprinklers extended from <br /> pipe in heated areas <br /> • Heat tracing <br /> 18. Insulation- Piping covered by insulation, as shown in the detail below is ❑ ❑ ❑ <br /> considered part of the area below the ceiling and not part of the unheated attic <br /> area. <br /> Fire Marshal's Office 425.257.8100 1 everettwa.gov/fire INFORMATION HANDOUT C-6 4.13.2020 I Page 6 <br />
