Venting Methods; Calculating Vent System Length; Ductless Conversion - Victory Q5 User Manual

IMPORTANT:
• A minimum of 6" round (standard for this range hood) or 3-1/4 x 10" rectangular duct (purchased separate-
ly) must be used to maintain maximum airflow efficiency.
• Always use rigid type metal/aluminum ducts if available to maximize airflow when connecting to provided
duct.
• Please use Duct Run Calculation below to compute total available duct run when using elbows, transitions
and caps.
• ALWAYS, when possible, reduce the number or transitions and turns. If long duct run is required, increase
duct size from 6" to 7 or 8". If a reducer is used, install a long reducer instead of a pancake reducer. Reduc-
ing duct size will restrict airflow and decrease airflow, thus 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.
• Minimum mount height between range top to hood bottom should be no less than 24".
• 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 to manufacturer's height clearance requirements and recommended hood mounting
height above range.
Minimum Duct Size:
• Round- 6" minimum
• Rectangular- 3-1/4 x 10" minimum (requires a 6" to 3-1/4x10" adaptor not supplied)

Calculating vent system length

To calculate the length of the system you need, deduct the equivalent feet for each vent piece used in the system
from the recommended maximum duct run.
Duct Run Calculation:
Recommended maximum run
6" or 3-1/4 x 10" duct
Vent piece deduction
Each 90º elbow used
Each 45º elbow used
Each 6" to 3/14 x 10" transition used
Side wall cap with damper
Roof cap
Duct Run Calcuation example:
50 ft
One roof cap, two 90º elbow, and one 45º elbow used:
0' + 9'+ 9'+ 5' = 23' used.
Deduct 23' from 50', 27' maximum available for
9 ft
straight duct run.
5 ft
7 ft

Venting Methods

• This built-in range hood is factory set for venting through the roof or wall. For non-vented (re-circulating)
installations, see Ductless Conversion (Non-Vented) below.
• Vent work can terminate either through the roof or wall. To vent through a wall, a 90° elbow is needed.
IMPORTANT:
• 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 rigid metal/aluminum duct work only.
• Fasten all connections with sheet metal screws and tape all joints with ALUMINUM TAPE.
• Use caulking to seal exterior wall or roof opening around the cap.
