Venting Methods

This canopy hood is factory set for venting through the roof or wall.

A 6" (15.2 cm) round vent system is needed for installation (not

included). The hood exhaust opening is 6" (15.2 cm) round.

NOTE: Flexible vent is not recommended. Flexible vent creates

back pressure and air turbulence that greatly reduce

performance.

Vent system can terminate either through the roof or wall. To vent

through a wall, a 90° elbow is needed.

Rear discharge

A 90° elbow may be installed immediately above the hood.

For Non-Vented (recirculating) Installations

If it is not possible to vent cooking fumes and vapors to the

outside, the hood can be used in the non-vented (recirculating)

version, fitting a charcoal filter and the deflector. Fumes and

vapors are recycled through the top grille.

Calculating Vent System Length

To calculate the length of the system you need, add the

equivalent feet (meters) for each vent piece used in the system.

The following example falls within the maximum recommended

vent length of 35 ft (10.7 m).
