Preparing the Install Location

Mounting Bracket - The mounting bracket and hood must be centered over the range. If the range is not in place, the center marking should be relative to it’s ﬁnal position. Refer to page 7 for bracket mounting points, rear access holes and access points.

Ductwork - The ductwork and ﬁttings used for outside venting (if applicable) must be carefully selected to ensure that the static pressure is in line with the fan parameters. The table below displays maximum duct length allowed for the various fan options.

Hood Width

30 inches

36 inches

Maximum duct length equals horizontal and vertical duct runs plus duct components such as ﬁttings, elbows, and transitions.

Duct Length

(maximum)

For installations requiring vertical duct venting to an inline fan and NFPA 101 compliance, the hood should be adapted from a 7-inch round duct access hole to a minimum 12-inch duct.

For installations requiring vertical duct venting to an inline fan and NFPA 101 compliance is NOT required, the hood can be adapted to a minimum 10-inch duct.

WARNING

The amount of fittings and ductwork directly affects the resistance or static pressure placed on the system. If the system is not within the proper static pressure range, the heat sensors and controls will be adversely affected and will impact the proper function of the safety controls. Therefore it is required that airflow testing be recorded along with installation documentation. The air testing is accessed by the removal of the grease tray and measured with an airflow pressure gauge.

Static Pressure Testing - The magnehelic gauge test port opening is located beneath the grease tray. The static pressure needs to be measured to ensure airﬂows meet design criteria. The airﬂow is measured by attaching the gauge tubing to the magnehelic gauge inlet, and the hood ﬁtting is attached to the grease drain hole beneath the grease tray.

A reading of 0.45 to 0.85 inches wg. is required to meet design standards. This reading will correspond to the static pressure of the ductwork, hood and fan combination.

Fans

For inline fans and exterior wall fans, fan location and proper mounting will be required.

If the hood system is conﬁgured for front recirculation discharge or rear discharge and NFPA 101 compliance, the unit will come equipped with a fan box. If installing under cabinets, keeping the fan box ﬂush to the underside of cabinet will guarantee correct spacing. Otherwise, center and mark the installation area according to wall mounting bracket prior to hanging.

The following steps will be required.

1. Insert/attach the top portion of the manual pull kit conduit through the fan box.

Accessories

Location restrictions will apply if the hood system supplied is provided with any of the optional accessories:

• ClockBox

• Remote ADA Switches

• Manual Pull Station

2. Attach square duct collar to the bottom of the fan box with included hardware.

3. Attach the fan box to the mounting bracket with included 8/32 nuts, then complete the installation on the manual pull kit conduit and top/bottom unions.

When prepping a space for installation, a 4-

⁄16 inch space must be allowed between the top of the mounting bracket and the bottom of the cabinet for the fan box. The additional height of the unit should not result in reduced range clearance. Cabinets should be installed approximately 5 inches higher to accommodate the additional size of the NFPA 101 fan box assembly.

Installing Fan (if applicable)

Inline

Install fan vertically in ductwork running between the unit and roof cap.

For best results, use as few elbows or transitions as possible. If necessary, long radius elbows or bends are recommended.

To attach ductwork, use duct tape at inlet and outlet to assure a good seal. If using fan clamps, attach clamps and insert screws through clamp into inlet and outlet ﬂanges.

CAUTION

Use sheet metal screws to secure ductwork to inlet and outlet. It is critical that the screw penetrate the metal of the ﬂange, but not so far as to bind the impeller. It may be necessary to angle screws away from impeller.

Inline Exhaust Fan - NFPA

Wall Mounted Fan

Fasten the fan box to an external wall via the four

0.27-inch mounting holes.

Run electrical through the 0.81-inch hole towards the top right corner of the box.

Attach ductwork using duct sealant, caulk, or tape to all seams to prevent air leakage and maximize air performance.

For best results use as few elbows or transitions as possible. If necessary, long radius elbows or bends are recommended.
