Vitorond 100, VR1 Technical Data Installation System Design Considerations Chimney For proper operation of the Vitorond boiler, all products of combustion must be safely vented to the outdoors, while ensuring that flue gases do not cool prematurely. It is critical that the chimney system be properly designed to handle the flue gas temperatures which the Vitorond boiler produces.
Installation System Design Considerations Vitorond 100, VR1 Technical Data (continued) Water quality Treatment for boiler feed water should be considered in areas of known problems, such as where a high mineral content and hardness exist. In areas where freezing might occur, an antifreeze may be added to the system water to protect the system. Please adhere to the specifications given by the antifreeze manufacturer. Do not use automotive silicate based antifreeze.
Installation Vitorond 100, VR1 Technical Data System Design Considerations Waterside flow (continued) Flow rates The relationship between boiler flow rate and temperature rise is according to the formula: Boiler output (Btu/h) = 500 x flow (USGPM) x Rise (°F) The following chart lists typical flow rates for the Vitorond boiler: Boiler Model VR1 -22 -27 -33 20° F rise USGPM 30° F rise USGPM 8 9.2 12.2 5.3 6.1 8.1 Boiler Model VR1 -40 -50 -63 20° F rise USGPM 14 17.2 21.
