IMPORTANT:
DO NOT USE ANY TYPE OF DAMPER IN A BBQ HOOD APPLICATION.
IMPORTANT:
Even though the intake side of the roof cap or wall cap may be properly sized, roof caps or wall caps
with built-in dampers must be made so that when the damper is fully open, the actual open area of the
final air path is equal to or greater than the discharge port of the ventilator. Any undersized portion of a
roof cap or wall cap will cause excessive static pressure that may result in rattling, vibration and air
buffeting noises, as well as inadequate ventilation.

4. DAMPERS
In ventilation systems utilizing a roof cap or wall cap with a built-in damper, remove it. Dampers are unnecessary and will
cause increased static pressure (air resistance), that may result in rattling, vibration and air buffeting noises, as well
as inadequate ventilation.
The roof cap or wall cap is the termination point of the venting system that allows the exhaust air to exit to the outdoors.
All sections of this fitting must have an equal or greater air path area than the ventilator’s discharge port. If any section
of the roof cap or wall cap is smaller than the ventilator’s discharge port, the entire ventilation system will lose
efficiency and the restriction will cause increased static pressure and decrease performance.
5. ROOF CAPS & WALL CAPS
Do not use “goose-neck style” caps as they significantly restrict natural, heated air-flow. Do Not
use caps with dampers for BBQ Hoods.
6. ATTACHING DUCT TO HOUSE FRAMEWORK
The ventilation system should be attached to the framework in such a manner that the weight of the duct and fittings is
supported with no stress on the duct joints, fittings or on the ventilator. All ducting should be attached so as to avoid
any possible duct vibration from being transferred to the house’s framework.

ROOF CAP DRAWING
For higher profile roof tile, you may need a taller roof cap. See recommended dimensions below – Minimizes static
pressure and maximizes air flow to ensure optimum performance of your TRADE-WIND® product.
