Thermador PR364GDH Installation Instruction

English 3

appliance should be installed in accordance with the 
National Fuel Gas Code ANSI Z223.1/ NFPA 54 current 
issue and National Electrical Code ANSI/NFPA 70 -current 
issue. In Canada, installation must be in accordance with 
the CAN 1-B149.1 and .2 – Installation Codes for Gas 
Burning Appliances and/or local codes. 

It is the responsibility of the owner and the installer to 
determine if additional requirements and/or standards 
apply to specific installations. 

It is strongly recommended that a suitable exhaust hood be 
installed above the range. Downdraft ventilation should not 
be used. The following table indicates the ventilation hood 
options and blower capacity guidelines that are 
recommended for use with all Thermador ranges.

1. Select Hood and Blower Models: 
•

For wall installations, the hood width must, at a 
minimum, equal the width of the range 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 range cooking surface by 3" on 
each side. 

Ventilation hoods and blowers are designed for use with 
single wall ducting. However, some local building codes or 
inspectors may require double wall ducting. Consult local 
building codes and/or local agencies, before starting, to 
assure that hood and duct installation will meet local 
requirements. 

Do not install a microwave oven/ventilator combination 
above the range, as these type of units do not provide the 
proper ventilation and are not suitable for use with the 
range. 

2. Hood Placement: 
•

For best smoke elimination, the lower edge of the hood 
should be installed 30" above the range cooking 
surface. (See Figure 1). 

Most range hoods contain combustible components which 
must be considered when planning the installation.

•

If the hood contains any combustible materials (i.e. a 
wood covering), it must be installed a minimum of 40" 
above the cooking surface. 

3. Consider Make-Up Air: 
•

Due to the high volume of ventilation air, a source of 
outside replacement air is recommended. This is 
particularly important for tightly sealed and insulated 
homes. 

•

A qualified heating and ventilating contractor should be 
consulted.
