DCS -IVH-48 - Manual (Page 6)

We recommend that a backdraft damper be used in all Vent Hood installations. Cold
weather installations necessitate the use of a backdraft damper to minimize the flow of
cold air into the room. A non-metallic thermal break should also be installed to mini-
mize conduction of outside temperatures through the ductwork. Locate the thermal
break as close as possible to where the ducting enters the heated portion of the
house.
Before beginning installation of the Island Vent Hood and Ventilator, PLAN OUT the
entire installation procedure beforehand, considering the following areas:
HOOD SIZE & LOCATION- (The hood should be as wide or wider than the cooking
appliance with the hood being centered on the appliance. Vertically, the bottom of
the hood should be between 30 ”-36” above the appliance cooking surface.)
DUCTING- (ducting transitions, air must flow to outside, use of Backdraft
damper...etc.)
ELECTRICAL REQUIREMENTS- (120 Volts, 60 Hz, 15 AMP Service, Local
Codes...etc.)
ADEQUATE MOUNTING SURFACES- (To support the weight of the vent hoods,
location of ceiling studs, additional support for safe ceiling mounting...etc.)
HANDLING NOTE- This Hood has been inspected prior to shipping to be free of
defects. Due to the weight of the Island Vent Hood and Ventilator; and to prevent
scratching or denting the unit, we recommend the use of two installers to move,
place, and secure the Vent Hood to avoid personal injury or damage to the Hood.
