such systems including those Codes and Standards, and Specification requirements,
which are mandated by Local Jurisdictions, and/or Utilities, having authority. Local
Jurisdictions, and/or Utilities, having authority, should be consulted prior to installation
to assure applicable Codes and Standards compliance.
4.3.2 Venting systems, incorporating flue gas exit breeching and chimney systems,
shall be properly designed by an experienced, and competent, Licensed Design
Professional Engineer.
4.3.3 This Equipment is factory sealed to accommodate pressurized firing and
specifically designed for forced draft fuel burning firing equipment. A standard
breeching slip connect locking quadrant butterfly flue gas outlet damper is provided to
assist adjustment and setting for proper combustion characteristics. Optional opposed
multi-blade dampers, for use with a sequence draft control system, are available, for
use on multiple boiler installations utilizing common breeching and/or where breeching
and chimney natural draft effect may inhibit adjustment and setting of proper
combustion characteristics.
4.3.4 Flue gases shall be directed towards main chimney by a natural draft breeching,
or stub vent system. It is recommended that flue gas venting be accommodated
through a natural draft breeching system in order to prevent positive pressurization
of breeching and chimney systems during normal operation. Breeching and chimney
systems shall be designed, installed and maintained in a manner as to prevent
any source of leakage, or directive path of flue gases, into, or about, any and all
environments, which may be occupied. Use extreme care in placement of fresh air
intake louvers, vents or mechanical ventilators so as to assure flue gas venting directive
path is free and clear of fresh air intakes in order to prevent introduction of vented flue
gases into, or about, any and all environments, which may be occupied.
4.4 Combustion and Ventilation Air Supply
4.4.1 Combustion and ventilation air supply systems shall be provided for in
accordance with the most current accepted Editions of any, and all, applicable
Codes and Standards governing the design, handling, installation, commissioning,
operation, care and continued maintenance of such systems including those Codes and
Standards, and Specification requirements, which are mandated by Local Jurisdictions,
and/or Utilities, having authority. Utilities, having authority, should be consulted prior to
installation to assure applicable Codes and Standards compliance.
4.4.2 Combustion and ventilation air supply systems, shall be properly designed by an
experienced, and competent, Licensed Design Professional Engineer.
4.4.3 Adequate combustion and ventilation air supply systems shall be provided
to accommodate proper combustion of fuel oil, and/or natural gas, maintenance
of ambient temperatures to assure safe and required equipment and component
temperature limits and provide comfort levels for operating and maintenance personnel
within environment.
