Install the ductwork

(ducted installation only)
Roof cap
Hood
30'' min. above
cooking surface
Hood installation height above a cooktop, rangetop or range can vary.
To obtain the necessary installation height above a cooktop, rangetop
or range, consult the appliance's installation manual or combination
guide.
NOTICE: The hood can be damaged from excessive heat if a cooktop,
rangetop or range is operated with multiple burners at high settings
under a hood that is installed at minimum clearances and is turned off.
Distance From Cooking Surface
The installation height above a cooktop, rangetop or range is
recommended as a minimum height of 30'' (762 mm); however, it is
necessary to follow the cooking appliance manufacturer's installation
instructions for proper hood height.
Refer to local building codes for the latest requirements or restrictions
when installing ventilation products.
NOTE: To reduce the risk of fi re, use only metal ductwork.
The size of the ducting varies according to the model installed:

1. Decide where the ductwork will run between the hood and the outside.
2. A straight, short duct run will allow the hood to perform most effi ciently.
3. Long duct runs, elbows, and transitions will reduce the performance
of the hood. Use as few of them as possible. Larger ducting may be
required for best performance with longer duct runs.
4. Install wall cap or roof cap (sold separately). Connect metal
ductwork to cap and work back towards the hood location. Use 2"
metal foil duct tape to seal the joints between ductwork sections.
NOTE: The manufacturer is not responsible for performance complaints
attributable to the duct section.

Ductwork preparation

DUCTING RECOMMENDATIONS

Proper performance is dependent upon proper ducting.
MAKE-UP AIR: Local building codes may require the use of make-up air
systems when using ducted ventilation systems greater than specifi ed
CFM of air movement. The specifi ed CFM varies from locale to locale.
It is the responsibility of the owner and the installer to determine if
additional requirements and/or standards apply to specifi c installations.
DO NOT USE FLEXIBLE DUCT; it creates back pressure/ air turbulence
and reduces performance.
Always install a metal vent cover where the ductwork exits the house.
COLD WEATHER installations should have an additional backdraft
damper installed to minimize backward cold air fl ow and a nonmetallic
thermal break to minimize conduction of outside temperatures as part
of the ductwork.
The damper should be on the cold air side of the thermal break. The
break should be as close as possible to where the ducting enters the
heated portion of the house.
For safety reasons, ducting should vent directly outdoors (not into
an attic, underneath the house, into the garage or into any enclosed
space). In gas cooking applications, the unit cannot be used in
conjunction with a recirculation unit.

THERMADOR recommends not exceeding 50 ft. (15 m) of equivalent
duct. See next page for Duct Equivalent Chart.
