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 ventilation hood options and blower capacity guidelines that are

recommended for use with all THERMADOR® ranges.

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.

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 a minimum of 3" (76mm) on each side.

2. Hood Placement:

•For best smoke elimination, the lower edge of the hood should be installed 30" (762mm) above the range cooking surface (see “Figure 1: Cabinet Clearances” on page 5).

•If the hood contains any combustible materials (i.e. a wood covering), it must be a minimum of 36" (914mm) 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.

NOTICE:

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

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.

Range	Range Top	Cubic Feet per Minute	Ventilation Options
Width	Configuration	(min requirement)
	4 burners with griddle	800 (cfm)	36” or 42” Pro Wall Hood
36”			36” Custom Insert w/ optional blower
	6 burners	1100 (cfm)
			42” or 48” Island Hood w/ optional blower
48”	6 burners with griddle	1200 (cfm)	48” or 54” Pro Wall Hood
			48” Custom Insert w/ optional blower

Important Notes:

It is recommended that a THERMADOR PROFESSIONAL® wall or island hood or custom insert is used with THERMADOR

PROFESSIONAL® Ranges. Refer to www.thermador.com for a complete selection of Professional Ventilation options, Blowers, and Accessories.

* For high output gas ranges (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is recommended. If the range has a griddle, add 200 CFM to the estimated blower capacity. Additional blower capacity may be required for longer duct runs.

For island applications, it is recommended to use a hood width that exceeds the width of the range by 6” (152mm), overlapping the range by a minimum of 3” (76mm) on each end.

CFM = “cubic feet per minute” (standard blower capacity rating).
