System Design Vitorond 200, VD2A Technical Data System Design Considerations Burner calibration Venting (option #1) With 2-stage and fully modulating burners, ensure that the chimney is compatible with the lower flue gas temperatures associated with partial load conditions set on the burner. The Vitorond 200, VD2A boiler is approved as a Category I appliance and must be vented accordingly. WARNING When installing or insulating (overhead) piping or venting, do not stand on top panel of boiler.
System Design Vitorond 200, VD2A Technical Data System Design Considerations (continued) Barometric draft regulator type Venting (option #2) For natural gas or propane applications, use a doubleacting type. The Vitorond 200 boiler is a Category III positive pressure non-condensing boiler. For #2 fuel oil applications, use a single-acting type. Each boiler must be vented individually.
System Design Vitorond 200, VD2A Technical Data System Design Considerations (continued) Combustion air supply Water quality and freeze protection The boiler must not be located in areas or rooms where chemicals containing chlorine, bromine, fluorine, or other corrosive chemicals are stored. Examples include refrigerants, bleach, paint, paint thinner, hair spray, cleaning solvents, water softener salt, etc. The combustion air must not be contaminated with any amount of the above mentioned chemicals.
System Design Vitorond 200, VD2A Technical Data System Design Considerations (continued) Sound attenuation Anti-vibration measures Please consult a professional engineer who is specialized in noise attenuation for advice. Anti-vibration supports can be field supplied as an economical and effective solution to combat noise generated. The burner/boiler systems, circulation pumps and other auxiliary equipment used in heating systems generate noise.
