Remettre les portes et les fenêtres, lesventilateurs, les registres de cheminées et lesappareils au gaz à leur position originale.g) Any improper operation of the common ventingsystem should be corrected so the installationconforms with the National Fuel Gas Code, ANSIZ223.1/NFPA 54. When resizing any portion of thecommon venting system, the common ventingsystem should be resized to approach the minimumsize as determined using the appropriate tables inAppendix F in the National Fuel Gas Code, ANSIZ223.1/NFPA 54 and or CAN/CGA-B149 InstallationCodes.Tout mauvais fonctionnement du systéme d'évacu-tion commun devrait étré corrigé de façor quel'installation soit conforme au National Fue GasCode, ANSI Z223.1/NFPA 54 et (ou) aux codesd'installation CAN/CGA-B149. Si la grosseur d'unesection du système d' évacuation doit étré modifiée,le système devrait étré modifié pour respecter lesvaleurs minimales des tableaux pertinents del'appendice F du National Fuel Gas Code, ANSIZ223.1/ NFPA 54 et (ou) des codes d'installationCAN/CGA-B149.GENERAL PIPING REQUIREMENTSCAUTION: Improper piping of this boiler/water heaterwill void the manufacturer's warranty and can causeboiler failure resulting in flooding and extensiveproperty damage! Excessive water hardness causingscaling in the copper heat exchanger tubes is NOTcovered under the manufacturer’s warranty.Excessive pitting and erosion of the internal surfaceof the copper heat exchanger tubes is NOT coveredunder the manufacturer’s warranty if the result ofhigh water flow rates, see Table 7. Return watertemperatures below 125°F, 52°C will result in heatexchanger damage from excessive condensationvoiding the manufacturer’s warranty, see Primary/Secondary Piping Figure 11.NOTE: Shut off valves and unions should beinstalled at the inlet and outlet connections of theboiler/water heater to provide for isolation of the unitshould servicing be necessary.Table 7 - Temperature Rise TableΔT = 15 °F ΔT = 8.3 °CModel Flow Rate Pres.
