Step 1: Ventilation Requirements - Thermador PRO-GRAND PRG30 Manual De Instalación

Check local building codes for the proper method of
appliance installation. Local codes vary. Installation,
electrical connections and grounding must comply with all
applicable codes. In the absence of local codes the
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.
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 table on page 4 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. Where space
permits, a hood larger in width than the range may be
desirable for improved ventilation performance.
• For island installations, the hood width should, at a
minimum, overhang the range by 3" on each side.
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. Use a 36" minimum clearance if the hood
contains any combustible materials such as a wood
covering. (See Figure 1).
NOTICE:
Most range hoods contain combustible components which
must be considered when planning the installation.
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.
