Greenheck GCE-402 Installation Manual

Combination Exhaust Louver/Backdraft Damper
J Blade
Application and Design
GCE-402 is a combination weather louver and gravity backdraft damper designed to protect air exhaust openings in building exterior wall. Design incorporates a drainable head member, J style stationary louver blades, pressure/gravity operated damper blades and sloped sill to provide maximum resistance to rain and weather. Recommended application is in close proximity (preferably ducted) to an exhaust air fan as pressures required to operate the GCE-402 may exceed pressure differentials available without an adjacent fan. This model is not recommended for barometric relief applications.
