e)  Test for spillage at the dra  hood relief opening a er 5 minutes 
of main burner operation. Use the  ame of a match or candle, 
or smoke from a cigare e, cigar or pipe. 
  Faire fonctionner le brûleur principal pendant 5 min ensuite, 
déterminer si le coupe-tirage déborde à l'ouverture de décharge. 
Utiliser la  amme d'une allune e ou d'une chandelle ou la 
fumée d'une cigare e, d'un cigare ou d'une pipe.
f)  A er it has been determined that each appliance remaining 
connected to the common venting system properly vents when 
tested as outlined above, return doors, windows, exhaust fans, 
 replace dampers and any other gas-burning appliance to their 
previous condition of use.
  Une fois qu'il a été d éterminé, selon la métode indiquée ci-
dessus, que chaque appareil raccordé au système d'évacuation 
est mis à l'air libre de façor adéquate. Reme re les portes et les 
fenêtres, les ventilateurs, les registres de cheminées et les appareils 
au gaz à leur position originale.
g)  Any improper operation of the common venting system should 
be corrected so the installation conforms with the National Fuel 
Gas Code, ANSI Z223.1/NFPA 54. When resizing any portion 
of the common venting system, the common venting system 
should be resized to approach the minimum size as determined 
using the appropriate tables in Appendix F in the National Fuel 
Gas Code, ANSI Z223.1/NFPA 54 and or CAN/CGA-B149 
Installation Codes.
  Tout mauvais fonctionnement du systéme d'évacu-tion commun 
devrait étré corrigé de façor que l'installation soit conforme au 
National Fue Gas Code, ANSI Z223.1/NFPA 54 et (ou) aux 
codes d'installation CAN/CGA-B149. Si la grosseur d'une section 
du système d' évacuation doit étré modi ée, le système devrait 
étré modi é pour respecter les valeurs minimales des tableaux 
pertinents de l'appendice F du National Fuel Gas Code, ANSI 
Z223.1/ NFPA 54 et (ou) des codes d'installation CAN/
CGA-B149.
GENERAL PIPING REQUIREMENTS
  Improper piping of this boiler/water heater will void 
the manufacturer's warranty and can cause boiler failure 
resulting in  ooding and extensive property damage! 
Excessive water hardness causing scaling in the copper 
heat exchanger tubes is NOT covered under the 
manufacturer’s warranty. Excessive pi ing and erosion 
of the internal surface of the copper heat exchanger 
tubes is NOT covered under the manufacturer’s 
warranty if the result of high water  ow rates, see Table 
7. Return water temperatures below 125°F, 52°C will 
result in heat exchanger damage from excessive 
condensation voiding the manufacturer’s warranty, see 
Primary/Secondary Piping Figure 11.
 Shut o valves and unions should be installed at the 
inlet and outlet connections of the boiler/water heater 
to provide for isolation of the unit should servicing 
be necessary.
