DUCT RUNS - LENGTH
a. ) Configure the ventilation duct run to be as short and as direct to the outside as possible. Minimize the number of
elbows and transition fittings used. Complex or long runs should be reviewed by a qualified installer.
b. ) No portion of the ducting should be run so that the exhaust air flows downward. Since exhaust heat rises, forcing the
air to flow downward will cause increased static pressure. As previously mentioned, improperly installed duct pipe
will cause excessive static pressure (air resistance), that may result in rattling, vibration and air buffeting
noises, as well as inadequate ventilation.
c. ) Duct runs for 1200 CFM ventilator models should not exceed 35 linear feet with two 90-degree elbows and two 45-
degree elbows, a damper and a roof or wall cap. Longer runs or additional elbows will result in decreased ventilation
performance. Each 90-degree elbow is the equivalent of 6 linear feet of duct pipe; each 45-degree elbow is equivalent to
3 linear feet of duct pipe.
d. ) Always run ventilator ducts to the outdoors. DO NOT terminate a duct into an attic, basement, garage, crawl space
under a house, a chimney, other ducting or an enclosed room.
ADDENDUM TO INSTALLATION INSTRUCTIONS
1. BUILDING CODES
BBQ Hood Ventilators should be installed by qualified technicians familiar with state and local building codes.
2. DUCT PIPE & FITTINGS (ELBOWS, TRANSITIONS, ROOF & WALL CAPS)
a. ) Use round or rectangular rigid metal duct only. Where possible, use round duct as it creates the least 1. amount of static
pressure. DO NOT USE FLEX DUCT.
b. ) All duct sections and fittings (EXCEPT DAMPERS, per Section 4), should overlap and be connected with at least 3 – 4
equally spaced screws and wrapped tightly with 2 – 3 layers of Aluminum Foil Metal Duct Tape. This type of duct tape is more
durable than traditional cloth duct tape. DO NOT USE BUTT JOINTS.
c. ) For best air flow, elbows and pipe size transition fittings should not be directly connected to one another. Where
possible, always include at least 15 inches of straight pipe between fittings.
3. DUCT PIPE & FITTING SIZES
IMPORTANT:
Problems caused by the improper installations are not covered by the manufacturer's warranty.
IMPORTANT:
Undersized and improperly installed duct pipe and/or other ventilation components will cause
excessive static pressure (air resistance), that may result in rattling, vibration and air buffeting noises,
as well as inadequate ventilation.
IMPORTANT:
No portion of any length of duct pipe or fitting should be smaller than the discharge port of the
ventilator. This is very important because any type of restriction anywhere in the ventilation system will
cause increased static pressure (air resistance), that may result in rattling, vibration and air buffeting
noises, as well as inadequate ventilation.
