Thermador PRD486EDG Installation Instructions - Page 5

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 below indicates the Thermador hoods, by model number, that are recommended for use with all 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. 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 types 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 36" above the range cooking surface. (See Fig. 1). • If the hood contains any combustible materials (i.e. a wood covering), it must be a minimum of 36" 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.

This may be particularly beneficial for installations having a long duct run or when heavy usage of the grill is anticipated, in which improved capturing of the cooking exhaust is desired. ** Thermador offers a choice of remote (VTR1030D or VTR1530D) or internal (VTN1030C) blowers for use in wall installations. 2
