INTRODUCTION
GENERAL DESCRIPTION
The complete Universal Cook'n'Vent
System consists of the ventilator intake and a blower. See
Fig. 1. The blower is either an integral (mounted on the vent
intake in the cabinet under the cooktop) or a remote (roof or
outside wall mounted). When a remote blower is used, a
duct transition is mounted on the ventilator intake in place
of the integral blower to connect the intake to the ductwork.
The duct transition must be purchased separately.
The integral blower or duct transition can be mounted in
different positions on the intake to route ductwork to avoid
cabinet, building framing, utilities, etc. Important: To
allow for cleaning access, locate blower in the position
closest to the duct outlet.
The Universal Cook'n'Vent® System is available in 30-
inch, 36-inch and 45-inch models, with countertop trim in
either stainless, black, or white. It is intended for use with
any residential 30-inch, 36-inch or 45-inch model (Thermador
or other) gas or electric cooktop. It is not intended to be
used with any professional style cooktop or range.

STEP 1

PLAN THE INSTALLATION

Carefully follow the planning procedures listed below. See
Figure 2.
A. Determine whether a remote or integral blower will be
used. Remote blower installation requires 4 wires
plus a ground wire to run from the Cook'n'Vent
to the blower.
B. Make sure adequate cabinet and counter space has
been provided for unit service if required.
C. Minimize cross drafts created by adjacent open win-
dows, doors, air conditioning, old heating vents, re-
cessed ceiling lights, and traffic patterns which may
affect performance.
D. For gas cooktop installations make sure that a mini-
mum 10 square inch opening is provided in the toe-
kick or other cabinet area. Inadequate ventilation of
the cabinet below the cooktop may result in flame
outage when operating the vent system.
E. Provide "make-up air" to installation location to im-
prove performance and prevent problems, such as
fireplace chimney downdrafts.
F. Investigate potential ductwork routes and choose the
shortest possible route from the unit to an outside wall
