DUCT FITTINGS
Use this chart to compute maximum permissable lengths
for duct runs to outdoors.
For best results, use 10" diameter duct.
Note: Do not exceed maximum permissab/e equivalent lengths!
Maximum recommended duct
length for these hoods: 150 feet
Flexible ducting:
If flexible metal ducting is used, all the equivalent feet
values in the table should be doubled. The flexible metal
duct should be straight end smooth end extended ms
much mspossible.
Do NOTuse flexible plastic ducting.
Note'.Any home ventilation system, such as a ventilation hood, may
interrupt the proper flow of combustion air and exhaust required by
fireplaces, gas furnaces, gas water heaters and other naturally vented
systems. Tominimize the chance of interruption of such naturally vented
systems, follow the heating equipment manufacturer's guidelines and
safety standards such as those
published by NFPAand ASHRAE.
When applicable, install any
makeup (replacement) air system in
accordance with local building code
requirements. Visit GEAppliences.
