Selecting a Kitchen Ventilation System
Selecting a Kitchen Ventilation System
The kitchen ventilation system is one of the most important
appliances in the home. While the ventilator removes grease,
heat, moisture, cooking odors and combustion gases from
the kitchen and indoor environment, it also helps protect
a family’s health and improves the cooking environment.
When choosing a ventilator, be sure to select one
which fully meets your customers’ cooking performance
requirements and personal taste.
What is CFM?
Ventilation performance is measured in Cubic Feet of
evacuated air per Minute, or CFM. The Thermador
Professional® Series of ranges and cooktops, with their
increased heat and grease output, require 1000 to 1400 CFM
of ventilation power. Our other electric and gas products
require 300 to 1000 CFM (see chart on adjacent page).
Updraft vs. Downdraft Ventilation
Updraft ventilation (overhead hood), collects and removes
cooking vapors several feet above the cooking surface.
Because cooking vapors naturally rise, updraft systems
tend to be the most effective method of ventilation.
Downdraft systems provide an alternate method of providing
effective ventilation, for non-professional cooktops and
ranges. Downdraft systems integrate beautifully in island
or peninsula installations, because they don’t intrude in the
overall kitchen decor.
Integral vs. Remote Ventilation
A ventilation system’s blower may be located adjacent to
the intake (integral) or on the outside roof or wall of the
home (remote). Integral ventilators are installed with the
least disruption to the exterior structure of your home.
Thermador offers integral ventilators from 300 to 1000 CFM.
Remote ventilators are quieter, because the blower is
removed from the inside of the house. They also take up
less cabinet space and have a galvanized finish which can
be painted to match the exterior of the home. Thermador
offers remote ventilators from 600 to 1400 CFM.
Professional Performance or Standard Ventilation
The Thermador customer loves to cook. We have designed
ventilation systems to meet the performance requirements
from the higher output cooking appliances, to the more
standard fare. The chart on the adjacent page is a quick
selection guide of Thermador ventilation products best
suited to your customers’ cooking appliance.
Counter-level downdraft ventilators can disrupt the
cooking process by pulling flames away from the heat
source. The Thermador® Cook’N’Vent® downdraft system
telescopes up from behind the cooking surface a full 10",
drawing heat and fumes from the cooking vapors, not at
the heat source. When not in use, the Cook’N’Vent system
can be retracted flush with the countertop.

1 Updraft Width Guidelines:
3 Available Ceiling Height:
The minimum hood width recommended for wall
installation equals the cooktop or range width. Where
space is not restricted, a wider hood can be used to
increase your capture area. Island installations require
a greater capture area, therefore the hoods used
should overlap your appliance by a minimum of 3"- 6"
on either side.
Before selecting your updraft hood, check your available
installation space. This is determined by adding your
floor-to-countertop height, plus the recommended
spacing between your appliance and the bottom of
the hood, plus the height of the hood. See product
dimensions on pages 5 to 13.
2 Cook’N’ Vent® Width Guidelines:
The Cook ’N’ Vent system selected should match the
width of your cooktop. Thermador offers 30", 36" or 45"
widths. Due to the high performance requirements of
Professional-style appliances for the home, an overhead
hood is highly recommended.
NOTE:
Indoor Gas Grills:
The local codes may require a fire-rated construction for
installation of open gas grill appliances. Please check
with your local codes prior to installation.

Ducting Considerations
Ducting Considerations
Check the Local Codes:
Work with a qualified service technician, installer or ventilation
engineer to ensure that all local installation, electrical and
grounding codes are satisfied. Always refer to the specific
installation instructions for your ventilation product.
Minimize duct runs and limit the number of transitions:
The inclusion of elbows and transitions, as well as long
duct runs, can have a significant effect on the ventilation
performance and maximum duct run.
Do not use metal flex duct:
Metal flex duct is not recommended for use by The National
Uniform Mechanical Code standards.
Extreme weather conditions:
Cold weather installations require an additional backdraft
damper installed to minimize backward cold air flow. In
addition, a non-metallic thermal break is needed to minimize
conduction of cold air flow through 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.
Don’t place elbows and transitions back-to-back:
A gradually tapered transition is required between different
sizes of ducting. Placing two elbows or transitions next to
each other can cause a significant reduction in performance.
Include a 15-inch straight section between transitions
whenever possible.
High altitudes affect performance:
Ventilation systems are less effective at higher altitudes
(above 5,000 feet). When configuring your system, estimate
a 20% reduction in CFM performance. If this is not possible,
you can increase your duct size, or CFM to enhance
your performance.
Make-up Air may be required:
Newly built homes have tightly sealed doors and windows,
which can make your ventilation system less effective. Some
heating and air conditioning systems make allowances for
additional make-up air. At the very least, some replacement
air can be introduced by simply opening a window or door.
Please coordinate with your local heating and ventilation expert.
Do not use ducting smaller than 6":
Ducting smaller than 6", 4" dryer vent pipe or wall caps
are not recommended because they severely impair
ventilation performance.
Recirculating vs. Ducted Hoods:
Recirculating hoods recycle the air through a filter and
return it to the kitchen. These hoods will not remove heat,
moisture or combustion gases from the air. They will also
be less effective in reducing odors and smoke. All of
Thermador’s hoods are ducted.
Don’t use butt joints:
Try to use male/female connections with the male end
pointing in the direction of the flow. Tightly tape joints to
prevent vapors from escaping the duct.
Ducting must be vented to the outside:
For safety reasons, never terminate ducting into an attic, into
the garage, underneath the house or into any enclosed space.
For best air flow, use recommended duct size:
Thermador recommends the following in order of size:
1st
10" round duct
2nd
8" round duct
3rd
7" round duct
4th
31/4" x 10" duct
5th
6" round duct is the minimum acceptable
(See Thermador ventilator performance charts on
pages 7, 8 and 38)
Base performance calculations on smallest duct size:
For maximum performance, do not use a smaller duct size
than the recommended transition size from the hood. If you
do transition down in size, your performance calculations
are based on this smaller opening for the entire duct run.
Calculating Cubic Feet Per Minute (CFM):
Determine the equivalent duct length for your installation
using the equivalent duct lengths for commonly used
transitions (shown on the next page). The equivalent duct
length is computed as follows:
1. Compute equivalent duct length of all transitions:
Transition
Equivalent Feet
6" Wall Cap
3 1/4" x 10" to 6" dia. 90º elbow
Sub-total:
2'
10'
12'
2. Compute the equivalent length of all straight ducts:
Duct Segment
Equivalent Feet
4' of 3 1/4" x 10"
2' of 6" diameter duct
4'
2'
Sub-total:
6'
3. Sum Equivalent Lengths for transitions and straight
duct sections:
Transitions
12'
Straight Duct Lengths
6'
Total Equivalent Length:
18'
4. Compute CFM using the performance charts shown on
pages 7 and 8 and the equivalent length computed in step 3.
Base the equivalent length on the smallest diameter ducting
used in the system. For this example, you would determine
the CFM for 18' of 6" diameter duct.

APPLIANCE INSTALLATION:
Assembly of the Transition:
The PHE/PH_Z unit can be mounted on a wall or suspended
from a cabinet. Both vertical and horizontal discharge are
possible with either mounting method.
The transition supplied with the PHE/PH_Z hood mounts to the
top or rear of the hood depending on the discharge direction.
Discharge Directions:
The PHE/PH_Z hood is shipped ready for vertical discharge.
To change to horizontal discharge simply move the two
plates marked A in Figure 1 to the top of the hood. Each
plate is held in place by two sheetmetal screws.
1. Align mounting holes at base of transition with mounting
holes on 1/2” flange located at the top or rear of the hood
depending on direction of discharge.
2. Fasten transition to hood using screws provided.
3. Duct tape connection between transition and hood.
4. Remove tape holding damper closed.

1. After the hood installation height has been determined, draw a
horizontal line at a distance above the cooktop equal to the desired
hood installation height plus 15.5”. This line is the mounting
location of the wooden bracket shipped with the hood.
Figure 2 PHE & PH_Z
2. Find the centerline of the cooktop. Draw a vertical line along
this centerline up to the horizontal line drawn in step 1.
3. The PHE/PH_Z is mounted to the wall using a wooden bracket
shipped with the hood. Remove the bracket from the hood by
removing two shipping screws. Mark the centerline of the bracket.
4. Find studs behind the drywall by tapping the wall or using a stud
finder. Locate one stud on either side of the cooktop centerline to
use for mounting the wooden bracket as shown in Figure 3.
5. Align the top of the wood bracket along the horizontal line drawn
in step 1. Align the centerlines of the bracket and cooktop.
6. Drill a 3” deep 1/8” tap hole through the wooden bracket, drywall,
and into the stud.
7. Use 2 – 4 screws to attach the bracket to the wall as shown in
Figure 3. For support of longer hoods, use three or four studs
as available. Countersink the heads to prevent interference
with the hood.
Figure 3 PHE & PH_Z
8. On the wood bracket, mark the locations used to hang the hood
according to Figure 4.
9. Drill a 1/8” tap hole through the wooden bracket and drywall.
These screws do not need to go into the studs.
10. Screw 2 screws into the wood bracket leaving 1/4” of the screw
exposed for hanging the hood.

PHE & PH_Z HOODS WALL INSTALLATION GUIDELINES
11. Discharge Direction: Horizontal discharge requires a wall
cutout, as shown in Figure 5, to provide clearance for
the transition. The location of the cutout is determined
by the hood installation height.
The transition supplied with the PHE/PH_Z connects to
standard 10” round duct. Figure 6 shows the transition
connected for horizontal discharge.
Figure 7 below shows the PHE/PH_Z configured for vertical
discharge. Installations using this type of method require
a cutout in the ceiling to accommodate 10” duct and the
1/2” conduit carrying power to the unit.
Duct covers, sold separately, are available to cover the space
between the top of the hood and ceiling.

12. Hang the hood using slots I in Figure 8. Make sure the
wood bracket fits into the recess on the back of the hood.
13. Tighten the screws in slot I. Use slots I to level the hood.
14. From inside the hood, drive screws through holes J into
wooden bracket.
15. Drill a 3/8” tap hole through the center of the oval holes
K into the wall. Insert two wall anchors into drilled holes.
Tighten hood to wall anchors by installing 2 screws
with washers.
