MOUNT HEIGHTS & CLEARANCE
Minimum mount height between range top to hood
bottom should be no less than 25”
Maximum mount height should be no higher than 30”
It is important to install the hood at the proper
mounting height. Hoods mounted too low could result
in heat damage and fire hazard; while hoods
mounted too high will be hard to reach and will loose
its performance and efficiency.
If available, also refer range manufacturer’s height
clearance requirements and recommended hood
mounting height above range.
* Maximum ceiling clearance 106.5” at 27.5” hood
mounting height from stove (different models may
varies)
** For higher ceiling, extension of the chimney and
the decorative cover is available to purchase, if
require.
Ducting (not provided)
NEVER exhaust air or terminate duct work into spaces between walls, crawl spaces, ceiling, attics or garages.
All exhaust must be ducted to the outside.
Use Metal ductwork only.
Fasten all connections with sheet metal screws and tape all joints w/ certified Silver Tape or Duct Tape.
Duct Run Calculation:
Maximum run 6” or 3-1/4 x 10” duct 100FT
Deduct:
each 90 Elbow used 15FT
each 45 Elbow used 9FT
each 6” to 3/14 x 10” 1FT
transition used
each 3/14 x 10” to 6” 5FT
transition used
Side Wall Cap w/ damper 30FT
Roof Cap 30FT
e.g. – 1 roof cap, 2x90 elbows, 1x45 elbow
= 30’ + 30’ + 9’=69’ used,
31’ available for straight duct runs
DUCT SIZE
A minimum of 6” round duct must be used to
maintain maximum airflow efficiency.
Flexible ducts are provided for convenience, always
use rigid type metal ducts if available to maximizing
airflow.
Also use calculation (on left) to compute total
available duct run when using elbows, transitions
and caps.
ALWAYS, when possible, reduce the number or
transitions and turns. If required a long duct
increase duct size from 6” to 7 or 8”.
If a reducer is used, install a long reducer instead of
pancake reducer. Reduce duct size as far away
from opening as possible.
If turns or transitions are required: Install as far away
from opening and as far apart, between 2, as
possible.
