The top sensor well is used for the DHW sensor connected to the boiler control. The optional screw-in electric heating element is used in enameled solar and domestic water storage tanks as auxiliary or emergency heating. It should be mounted in a horizontal position by heating contractor. For solar heating systems, Viessmann recommends placement of the DHW tank temperature sensor in the solar collector return. WARNING To ensure optimum, safe operation, the stainless steel well must be installed. The well diameter is large enough to accommodate a wide variety of sensing bulbs. Always use spring clip to ensure proper contact of capillary bulb against the stainless steel well for proper sensing/heat transfer! WARNING To avoid damage to the screw head and/or heating element, do not operate the heating element without a medium. WARNING Ensure the heating element ground wire is securely connected to ground. Heating water supply temperature over 230º F (110ºC). These operating conditions require the installation of an additional safety high limit into the DHW storage tank, preventing the temperature from rising above 203ºF (95ºC). IMPORTANT A domestic hot water tempering valve must be used. Temperature and pressure relief valve The heating contractor must install a temperature and pressure relief valve (T&P relief valve) on each tank in a method meeting code requirements. If local codes require a different relief valve, substitute the manufacturer’s supplied valve. The tank is approved for 100 psig where a CRN is required. Maximum operating pressure is 150 psig. Maximum operating temperature is 210º F (99º C). The T&P relief valve must be tested under ANSI Z21.22 Code for Relief Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems. WARNING Do not operate the heating element without a medium. Damage to the heating element and screw head may occur if operated without a medium. Backflow preventers 5470 954 v1.1 Where backflow preventers are required, a domestic water expansion tank installation must be installed in the cold water inlet piping before the cold water enters the Vitocell. For the backflow device, observe local plumbing codes and regulations. 11 12 Vitocell 100-VH/-BH Technical Data 5470 954 v1.1 Technical information subject to change without notice.
