Installation and Blower Selection
Guidelines
Guidelines
1. Distance from cooking surface:
of your cooktop width. For example, a 36” wide
cooktop requires a blower with a minimum of 300
For optimal performance, the distance from
CFM.
the cooking surface to the bottom of the range hood
should be between 24” and 30”, unless otherwise
noted. DO NOT install a Broan Elite range hood
less than 24” above cooking surface.
To maintain hood performance at heights greater than
the recommended range, use the following guidelines:
• High heat cooking or aromatic foods may require
additional CFM. Always check with the range
manufacturer. NOTE: Increasing capture area
by 3” on each side is also a recommended way
to address this issue.
Range hood should be
between 24” to 36”
unless otherwise noted.
• As a means to estimate the approximate CFM
• For every 3” increase in installation height,
add 100 CFM to the minimum exhaust requirement
and/or a minimum of 3” to the hood/liner width
(may require going to the next hood width).
requirement for cooktops OVER 60,000 BTUs,
choose a blower with 1 CFM per 100 BTU of
cooktop output. To quickly calculate this number,
add the BTU output from all burners and drop the
last two zeros. For example, if the total BTU output
2. Range hood width:
The range hood should never be less than the width
of the cooktop.
3. Required blower CFM based on cooktop BTU output:
• For cooktops UNDER 60,000 BTUs, choose a
blower with a minimum of 100 CFM per lineal foot
of the cooktop burners is 65,000 BTUs, choose a
blower with at least 650 CFM.
4. Additional CFM needs for a grill or griddle:
If your cooktop has a grill or griddle, ADD 200 CFM
to your estimated CFM needs as calculated in step
3. For example, if your cooktop BTU requires a 650
CFM blower, add 200 CFM for a total of 850 CFM.
INSTALLATION EXAMPLE:
A consumer purchases a cooktop
with these specications:
• Four burner, 36” cooktop
• Burner output is 60,000 BTU
• The cooktop features a grill.
• Installation requirements call
for the range hood to be 33”
over the range
(3” above recommended maximum height)
BLOWER CFM
Option 1
(Using the guidelines above)
The blower must equal
a minimum of 600 CFM
(60,000 BTU) + 200 CFM
(for grill requirement)
+ 100 CFM (for 3” of
installation height)
= 900 CFM
Option 2
(Using the guidelines above)
Select a range hood that
is a minimum of 3” WIDER
than the cooktop,
a minimum 600 CFM
(60,000 BTU) + 200 CFM
(for grill requirement)
= 800 CFM
Internal Blowers
Broan Elite internal blowers provide high ventilation and durable construction
to meet the needs of professional-style cooking appliances for the home.
• The P5 and P8** are designed for use with the Broan
Elite RMIP Insert.
• Rough-In Kits are included to make the installation
clean and simple.
