Immersion Thermostats with Contactors (CF Model): offer accurate temperature control to 180° F. Elements: screw in style Surface Mounted Thermostat models have nickel chromium wire embedded in magnesium oxide sheathed in copper and electroplated to minimize degradation of the anode. Incoloy sheathed elements are optional. Immersion Thermostat models have low watt density incoloy sheathed elements standard, which resists burnout caused by dry fire or lime buildup. Porcelain glass lined with dual magnesium anode rods: to prohibit corrosion for longer life. ASME and NSF Construction avaliable 3-Year Limited Warranty T&P Valve: Factory Installed Relief Valve Opening: 3/4” Warning: Do not install on combustible flooring. Installation should be in accordance with all national and/or local codes. In the absence of local codes, refer to NFPA 31, NFPA 54 or ANSI Z.21.10.1. Caution: The recommended maximum hot water termperature setting for normal residential use is 120°F. Bock recommends a tempering valve or anti-scald valve be installed and used according to the manufacturer’s directions to prevent scalding.
