Venting Requirements
The Venom BCMS must be vented to an external location to prevent accumulation of smoke in the event of a
catastrophic battery failure. Installation must conform to all local building codes or authority having jurisdiction and
should be performed only by a qualified HVAC specialist. Use only Type B double walled vent components which have
been designed for use with Category I appliances as the Venom BCMS is to be considered a heat producing appliance
during a catastrophic battery failure. The ventilation system must be installed to maintain clearance of at least 1” to
all combustible construction. Additionally the Venom BCMS must not share or be connected to a ventilation system
serving any other appliances. Multiple Venom BCMS units can share a dedicated ventilation system given all listed
requirements are met.
To ensure optimal operation, keep the overall vent piping length to a minimum avoiding any unnecessarily long runs
or unnecessary bends. Wherever possible, keep ventilation piping run lengths to no more than 10 feet by installing
the Venom BCMS at the location of an exterior wall. The use of any piping other than 4” should be avoided to keep
the system in negative pressure as the ventilation system serves only to evacuate smoke generated during a
catastrophic battery event.
Secure the selected venting material to the 4” exhaust flange at the rear of the Venom BCMS using #10 sheet metal
screws or similar fasteners. Please note that there are three predrilled holes in the flange. The remaining ventilation
components must be installed according to the manufacturers recommendations.
An inline booster fan is required as part of the venting system installation to ensure proper evacuation of smoke
generated during a battery event. This fan must be rated to withstand sustained temperatures of 200°F and
installation should be in accordance with the manufacturers specifications. Where possible, placement of the booster
fan should be at the end of the venting run and must supply 200CFM for every 2 cubic feet of exhaust piping volume.
The booster fan must remain on during operation of the Venom BCMS.
Improper installation can severely limit the effectiveness of the system's ability to contain a battery fire leading to
personal injury and/or property damage. With a properly installed and functioning ventilation system, a small amount
of smoke may exit the front of the Venom BCMS at the peak of a battery event.
