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.
