OUTSIDE WEATHER HOODS
The weatherhoods must have built-in screens to prevent birds and rodents from entering into the ductwork. The outside perimeter of the weatherhood must
be sealed to prevent leakage into the building. The design and size of the weatherhoods or louvers chosen by the installer must allow for adequate free area.
GOOD INSTALL PRACTICES
• Minimum distance not less than 10 ft. (3 m) apart from each other.
• Minimum 18 inches (457.2 mm) above snow line or ground level.
Outdoor intake air weather hood should be located to avoid contamination from sources such has:
• Exhaust Air openings
• Parking lots (auto exhaust)
• Combustion appliances
• Gas meters, oil fill pipes
• Garbage containers

DUCTING TO AND FROM THE ERV
Galvanized sheet metal ducting with cross section, insuring all joints and seams are sealed with an approved commercial grade duct sealant of aluminum
foil tape. The outdoor air and the exhaust air duct from the weather hoods to the ERV must be fully insulated to minimize heat loss or heat gain and to avoid
potential condensation.Insulated flex duct may be used in moderation, if sized and installed properly. (Consult local or national safety & building codes.)
NOTE TO INSTALLER:
The ERV is a balanced ventilation system is designed to introduce outdoor air to the building while exhausting the same amount from the building. The
designer and installer must comply in accordance to local or national safety & building codes.
IMPORTANT: Insure the ERV runs in conjunction with the forced air system (Ref. wiring diagram for interlock connection)
To maximize airflow in the ductwork system, all ducts should be kept has straight as possible avoiding bends as possible. Insuring all joints and seams are
sealed with an approved commercial grade duct sealant of aluminum foil tape.
Tips:
Supply air ducting
In buildings without a forced air systems, fresh air is supplied to all main living areas. To maximize comfort the fresh air distribution ensure to install the
