Step 1: Ventilation Requirements - Thermador PRG364GDH Installation Manual

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.
Step 1: Ventilation
Requirements
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.
Range Range Top
Width Configuration
30" 4 burners
4 burners with griddle
36"
6 burners
Important:
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).
NOTICE:
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.
