OUR EXCLUSIVE, PaTEnTED STaR® BURnER
The Star Burner’s unique shape isn’t just for show. It creates a
perimeter 56% longer than a round burner of the same size,
which allows the inclusion of more flame ports. The result is a
burner that delivers superior flame spread and a reduced cold
spot for faster and more even heating across any size pan.
And this latest generation features a more stylish shape and a
raised pedestal design for easier cleaning than ever before.

and electrical/gas connections. Also, always consult
with the installation manual packed with the product for
complete details before installing.
ELEcTRicAL AND GAS SPEciFicATiONS
Be sure your appliance is properly installed and
grounded by a qualified technician. Installation,
electrical and gas connections, and grounding must
comply with all applicable local codes.
GAS REQuiREMENTS AND hOOkuP
Verify that the type of gas being used at the installation
site matches the type of gas used by the appliance.
If an LP kit is utilized (PALPKITHC), conversion from
natural gas to propane must be done by qualified
service personnel only. Please refer to the LP Conversion
Instructions packed with product for further information.

Typical placement of the electrical and gas supply
can be found within the “Cutout and Range
Dimensions” located on the product pages. Alternate
placement within the supply zone is acceptable.
Dual-Fuel ranges may be connected to the power
supply with a range supply cord kit (sold separately)
or by hard-wiring to the power supply. All-Gas
ranges may be connected to the power supply with
the supplied range cord or by hard-wiring. It is the
responsibility of the installer to provide the proper
wiring components (cord or conduit and wires) and
complete the electrical connection as dictated by local
codes and ordinances and/or the National Electric
Code. The units must be properly grounded.
Installation of the range must be planned so that the
rough-in of the junction box for the receptacle or
conduit connection will allow maximum clearance to
the rear of the unit.
WARRANTY
Limited warranty parts and labor (1 year)
See page 294 for additional warranty details.
Warning: All ranges can tip,
causing injury. Install anti-tip
device packed with range.
VENTiLATiON REQuiREMENTS
We strongly recommend that a Thermador Professional Wall or Island Hood or
Custom Insert be installed with all Thermador Pro Harmony Ranges. Downdraft
ventilation should not be used. Do not install a microwave-hood combination
above the cooktop, as these types of units do not provide the proper
ventilation and are not suitable for use with Thermador Pro Harmony Ranges.
For high output gas cooktops (60,000 BTU or greater), the minimum of one
(1) CFM of ventilation per 100 BTU is recommended. If the cooktop has a grill
or griddle, add 200 CFM to the estimated blower capacity. Additional blower
capacity may be required for longer duct runs.
The following table indicates the ventilation hood options that are
recommended for use with Thermador Pro Harmony Ranges. Refer to the
Ventilation section or www.Thermador.com for a complete selection of
Professional ventilation options, blowers, and accessories.

iMPORTANT VENTiLATiON NOTES:
• Due to the high surface temperature output of the Pro Harmony Ranges,
the HPWB Professional Series Wall Hoods or the Professional Series Custom
Inserts are recommended ventilation solution for these ranges. The PH
Professional Series Wall Hoods are also a viable option, however the 27"
depth of the PH Series may not be suitable to all applications.
• For wall installations, the hood width must, at a minimum, equal the
nominal width of the appliance cooking surface. Where space permits,
a hood larger in width than the cooking surface may be desirable for
improved ventilation performance.
• For island installations, the hood width should, at a minimum, overhang the
appliance cooking surface by 3" on each side.
• Due to the high heat capability of these cooktops, particular attention
should be paid to the hood and duct work installation to assure it meets
local building codes.
• For best smoke elimination, the lower edge of the hood should be installed
30"– 36" above the appliance cooking surface.
• If the hood contains any combustible materials (i.e., a wood covering), it
must be 40"or greater distance above the cooking surface.
