Installation Guide

Installation of Ducting for Proper Operation:

IMPORTANT

Proper installation of ducting is extremely important for optimal performance of your ventilation system. It is a basic

requirement that the kitchen is provided with an air intake to ensure good air circulation and therefore proper operation

of the hood. Without this incoming air a depression could form that would reduce the efficiency of the ventilation

system. All CFMS are based on tests at 0.1 static pressure. Without static pressure all CFM’s would be overstated.

• Consult with local codes for make-up air requirements

• If ducts are combined the square inch area must reflect the total square inch area of the ducts being combined.

• Do not use flexible or corrugated duct. This type of duct will reflect airflow and reduce performance.

• Only use smooth, galvanized metal duct.

• Make the duct run as short and as straight as possible with as few turns as possible.

• Avoid sharp-angled turns. Use smooth gradual turns such as adjustable elbows or 45 degree angled turns.

• For duct runs over 20 feet increase the duct diameter by one inch for every ten feet of duct.

• Airflow must not be restricted at the end of the duct run.

• Damper is not provided. This must be included in duct run to prevent back drafts.

• Do not terminate venting into an attic or chimney.

INSTALLATION INSTRUCTIONS

Ventilation Hood Mounting Instructions:

Step 1: Read all instructions thoroughly before beginning installation. If a duct cover is being used please

proceed to page 13. For instructions on installing Manhattan style wall hoods proceed to page 15.

Electrical Specifications:

IMPORTANT

This hood is designed to be plugged into a 3-

prong ANSI or Non-GFCI outlet – 120Volt,

10amp. Ensure the outlet is not obstructed by

the duct run prior to installation.

To connect power to in-hood blowers insert

molex connector(s) into the opening located on

the side of blower motor.
