Installation Specifications
Installations with ILHSF-/REMP-series blowers:
• The downdraft vent can be configured to exhaust through
the back/bottom/sides by removing the proper exhaust
knock-out. (See Pg. 9.)
• When installing an ILHSF blower, minimize noise by
installing it as close as possible to the duct-system
exhaust. (Minimum recommended distance from the
downdraft vent is 5 feet.)
• When connecting the duct work to the back of the unit,
the customer must supply a 3¼ x 10 rectangular transi-
tion to make the connection.
• For side/bottom exhaust connections, use the supplied
transition to connect the duct work to the unit. It transi-
tions between the unit’s 1

x 16 exhaust outlet and a
3¼ x 10 rectangular duct connection. On bottom exhaust
installations, cut a hole in the floor so the transition and/
or duct work can pass through the floor. (See Pg. 13).
• On side exhaust installations, allow 5 in. on the side for
the 2 x 16 to 3 ¼ x 10 transition, plus space for the duct
attached to it (X).
Planning the Duct Work
WARNING
• To reduce risk of fire and to properly exhaust air, duct
air outdoors, not into any interior spaces or garages.
• TO REDUCE FIRE RISK, USE ONLY METAL DUCTING.
• DO NOT install multiple blowers to lengthen the duct
run. Even small differences between blower airflow
rates can greatly reduce the downdraft vent’s air draw.
Building codes may require makeup air systems with ven-
tilation systems that move air greater than the specified
movement rate (
CFM
). Consult a qualified
HVAC
specialist
when designing the system for the requirements in your
area and to assure optimal performance.
You
must
install a Dacor blower for the downdraft vent to
operate properly. See the blower installation instructions for
directions. For model CABP3, see the instructions later in
this manual.

For installations with CABP3 blowers:
• Installation requires Dacor adapter kit # AERVCAB.
• The blower assembly is mounted to the front of the down-
draft vent with the exhaust pointing in the desired direc-
tion. (See Pg. 10.)
• The CABP3 blower output connects directly to 3¼ x 10
rectangular ducting.
