Selecting a Ventilation System Selecting a Ventilation System When selecting a ventilation system, start by choosing the proper Wolf ventilation product, determined by the type of cooking appliance used and the following considerations: • Cooktop or pro ventilation • Updraft or downdraft • Width guidelines • Hood mounting height • Ceiling height • Cooking space / cooking style • Ventilation performance • Internal, in-line, or remote blower • Ducting considerations • Electrical requiremen
Selecting a Ventilation System Selecting a Ventilation System COOKTOP OR PRO VENTILATION Wolf pro ventilation hoods and liners can be used with all cooking appliances, including ranges and rangetops. A downdraft system can also be used with sealed burner rangetop models SRT304 and SRT366. The outdoor wall hood is specifically designed for outdoor use. One of the primary considerations in choosing a ventilation product is the type of cooking appliance used.
Selecting a Ventilation System Selecting a Ventilation System UPDRAFT OR DOWNDRAFT CEILING HEIGHT The choice between updraft ventilation and downdraft ventilation will depend on several factors, most notably the cooking appliance, type of installation, and location. Updraft ventilation, or an overhead hood, is typically a more effective ventilation option. Cooking vapors naturally rise, making it easier to collect and remove them from the cooking area.
Selecting a Ventilation System Selecting a Ventilation System INTERNAL, IN-LINE, OR REMOTE BLOWER DUCTING CONSIDERATIONS All Wolf ventilation products are shipped without the blower assembly. An internal, in-line, or remote blower must be selected to accommodate the cooking appliance and ventilation product. IMPORTANT NOTE: Unless used in a recirculating application, Wolf ventilation hoods and downdrafts must be vented to the outside. Use only rigid metal ducting.
Selecting a Ventilation System Selecting a Ventilation System Ventilation Made Easy RECIRCULATING APPLICATION After choosing the proper ventilation hood or downdraft, follow this three-step process to determine your blower needs to complete the ventilation system: Recirculating units recycle the air through a charcoal filter and return it to the kitchen. This type of ventilation will not remove heat, moisture, or combustion gases from the air. It will also be less effective in reducing odors and smoke.
Determine the Duct Run Step 1: Determine the Duct Run IMPORTANT NOTE: Consult a qualified HVAC professional for specific installation and ducting applications. Check local codes: Consult a qualified HVAC professional to ensure all applicable codes are followed. Refer to the installation guide for your specific Wolf ventilation product. Minimize the duct run: The length of the duct run and number of elbows and transitions can have a significant effect on ventilation performance.

Determine the CFM Step 2: Determine the CFM Ventilation performance is measured in cubic feet per minute, or CFM. The chart below provides CFM suggestions specific to the Wolf cooking appliance and ventilation system used. To maximize airflow and performance, specify a blower to match or exceed the CFM listed. WOLF PRODUCT CFM Additional CFM may be required for long duct runs and ranges or rangetops with a charbroiler or griddle.
Select a Blower Step 3: Select a Blower All Wolf ventilation products are shipped without the blower assembly. An internal, in-line, or remote blower must be selected to accommodate the cooking appliance and ventilation product. Wolf ventilation products must be installed only with a Wolf blower. Wolf blower assemblies are available through an authorized Wolf dealer. For local dealer information, visit the find a showroom section of our website, wolfappliance.com.
