3E. Common Venting System
When an existing boiler is removed from a common
venting system, the common venting system is likely
to be too large for proper venting of the appliances
remaining connected to it.
At the time of removal of an existing boiler, the
following steps shall be followed with each appliance
remaining connected to the common venting system
placed in operation, while the other appliances
remaining connected to the common venting system
are not in operation.
1. Seal any unused openings in the common venting
system.
2. Visually inspect the venting system for proper
size and horizontal pitch and determine there is
no blockage or restriction, leakage, corrosion or
other deciencies which could cause an unsafe
condition.
3. Insofar as it is practical, close all building doors
and windows and all doors between the space in
which the appliances remaining connected to the
common venting system are located and other
spaces of the building. Turn on clothes dryers
and any gas burning appliance not connected
to the common venting system. Turn bathroom
exhausts, so they will operate at maximum speed.
Do not operate a summer exhaust fan. Close
replace dampers.
4. Place in operation the appliance being
inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate
continuously.
5. Test for spillage at the burner opening after ve
minutes of main burner operation.
6. After 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 conditions of use.
7. Any improper operation of the common venting
system should be corrected so the installation
conforms with the National Fuel Gas Code,
ANSI Z223.1. When re-sizing any portion
of the common venting system, the common
venting system should be re-sized to approach
the minimum size as determined using the
appropriate tables in Appendix G in the National
Fuel Gas Code, ANSI Z223.1.
WARNING
Operation of appliances with a blocked common
vent may lead to serious injury or death. Safety
devices must be implemented to prevent blocked
common vent operation. If safe operation of all
appliances connected to a common vent cannot
be assured, including prevention of spillage of ue
gasses into living spaces, common venting should
not be applied, and appliances should each be
vented separately.
AVERTISSEMENT
Le fonctionnement des appareils avec un
système d’évacuation bloqué peut provoquer des
blessures graves, voire la mort. Des dispositifs
de sécurité doivent être installés pour éviter
le blocage des systèmes d’évacuation. Si le
fonctionnement de tous les appareils connectés
à un système d’évacuation commun ne peut
pas être assuré, y compris la prévention de la
dispersion des gaz toxiques dans les espaces
habités, on ne devrait pas installer un système
d’évacuation commun et chaque appareil devrait
être ventilé séparément.
