Cascade Venting of Multiple Boiler Installations
When multiple boilers of the same model size are installed within a common room it is permissible to cascade the venting connecting all
boilers to a single exhaust system. No more than eight (8) boilers should be cascade vented together.
The boiler/ vent installation must be in compliance with ANSI Z223.1/ NFPA 54 and all local, state, and federal regulations for building code.
Venting system shall be designed to maintain suitable vent pressure at the boiler exhaust collar.
For a list of suitable venting materials consult the installation manual section: “4.15 Venting” page 26
Adapters are available for various brands of venting materials. Consult the factory for a list of available adapters.
Venting components from different manufacturers shall not be mixed.
Adequate combustion air must be supplied to the boiler to ensure safe operation. A properly sized direct connected common combustion
air duct may be used for sealed combustion air to the boiler cascade.
For additional information regarding combustion air supply consult the installation manual section: “4.16 Combustion Air”
Prior to installing a permanent vent system refer to the Installation Manual, ANSI Z223.1/ NFPA 54, and all local, state, and federal regulations
for building code to ensure compliance with the requirements of these articles.
