VCH36/VCH54 Filter Housing Descriptions
These filter housings have been specially designed to
meet the ventilating requirements of our gas and electric
cooktops. Each ventilator unit includes a filter housing and
lights mounted on the mounting plate.
VCH36
VCH36 Requires:
• VTR600R, VTR1000Q, VTR1400Q (or equivalent)*
• VCHTR10 Transition*
• CTR3Q Control*
• Light switch. +

+ Part supplied by electrical contractor
BEFORE INSTALLING PLEASE NOTE:
1. The use of 10" round duct or equivalent rectangular duct is
acceptable for zero clearance. A Thermador VCHTR10
transitions from the rectangular hood opening to a 10"
diameter duct. Verify the installation will have enough
clearance for the transition and ducting.
2 A VCH54 with dual filters requires additional clearance
above the hood for the PLENUM transition. This transition is
shown in Figure 4 (back page) transitioning from the VCH54
to the VCHTR10.
3. For the most efficient ducting layout, use a straight run or
as few elbows as possible.
4. COLD WEATHER installations should have a backdraft
damper installed to minimize backward flow of cold air, and
a nonmetallic thermal break to minimize heat loss due to
conduction. The damper should be on the cold air side of the
thermal break. The break should be as close as possible to
the location where the ducting enters the heated portion of
the house.
5. Hood installation height above the cooktop is the user's
preference. The lower the filter housings are above the
cooktop, the more efficient the capture of cooking odors,
A remote mounted ventilator unit, VTR600R, VTR1000Q
or VTR1400Q must be purchased separately. The ventila-
tors require a separate speed control unit, CTR 3Q (pur-
chased separately), and a light switch or light dimmer
switch (supplied by the electrical contractor). The VCH54
unit requires a transition model PLENUM (sold separately).
VCH54
VCH54 Requires:
• VTR600R, VTR1000Q, VTR1400Q (or equivalent)*
• VCHTR10 Transition*
• CTR3Q Control*
• Light switch. +
grease, and smoke. Thermador recommends installing the
hood 30" to 36" above the countertop. The minimum hood
installation height is 30". This is the distance from the
cooktop to the bottom of the hood not the filter housing.
6. The VTR600R, VTR1400Q and VTR1000Q remote blowers
require five wire installations. See Installation Instructions
and Wiring Diagram supplied with these units.
7. Electrical power to the hood is for lights only. The light
control is supplied by the electrical contractor. The light
switch must be a UL listed general switch. Use 75 Watt
(maximum) reflector type light bulbs for 120 volts, 60 Hz.
The VCH36 has one built-in filter box and two lights. The
VCH54 has two built-in filter boxes and three lights. For
electrical connections see Page 4, Item 5.
8. DO NOT USE over solid fuel fired barbecue units.
9. If the filter housing is installed in a custom hood made from
combustible material make sure that clearances to combus-
tible materials specified in the cooktop installation instruc-
tions are satisfied.

1. The VCH36/VCH54 are designed to be
installed in a custom hood as shown in Figure
1A. Design of the hood must meet all building
code regulations and is the responsibility of
the contractor. For optimal performance, the
hood should overhand the cooking surface
and be installed at a height between 30-36
inches above the cooking surface. Clearance
in the hood is needed for opening the front
filter housing door to remove the filter for
cleaning (See Figure 1B).
