10fantechInterior ducting installation• To maximize airflow through the ductwork system, all ducts should be kept short and have as few bends or elbows as possible.• 45º elbows are preferable to 90º.• Use “Y“ ducts instead of “T” ducts whenever possible.• All duct joints must be fastened with screws or duct sealant and wrapped with aluminum foil duct tape to prevent leakage.• Galvanized ducting from the ERV to the living areas in the house is recommended whenever possible, although flexible ductingcan be used in moderation when necessary.• To avoid possible noise transfer through the ductwork system, a short length (approximately 300mm, 12’’) of nonmetallic flexibleinsulated duct should be connected between the ERV and the supply/exhaust ductwork system.• The main supply and return line to/from the ERV must have the same diameter as the duct connection or larger.• Branch lines to the individual rooms may be as small as 100mm (4’’).Installing duct to ERVFor flexible duct installation, slide flexible ducting onto duct connection. Theninstall a cable tie over flexible duct to prevent leakage between the ducting and theduct connection.In the case of solid ducting, slide duct over duct connection, screw in place and seal.SUPPLY AIR GRILLES LOCATIONIn homes without a forced air furnace, fresh air should be supplied to all habitable rooms, including bedrooms and living areas. It should be suppliedfrom high wall or ceiling locations. Grilles that diffuse the air comfortably are recommended. In homes with a forced air furnace, you may want to connectthe ERV to the furnace ductwork (see information below).EXHAUST AIR GRILLES LOCATIONThe stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is recommended that returnair ducts be installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations may be installed. The furnacereturn duct may also be used to exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the ERV with“dedicated lines”.As per building codes and installation requirements for combustion appliances:Air return ducts, or openings for air return, should not be placed in enclosed spaces containingcombustion appliances that are subject to spillage.
