9fantechExterior ducting installationWeatherhood location• Decide where your intake and exhaust hoods will be located.Locating the Intake Weatherhood• Should be located upstream (if there are prevailing winds) from the exhaustoutlet.• At a minimum of 2m (6’) away from dryer vents and furnace exhaust(medium or high efficiency furnaces), driveways, oil fill pipes, gas meters,or garbage containers.• At a minimum height of 460mm (18’’) above the ground, or above the levelof expected snow accumulation.• At a minimum distance of 1m (3’) from the corner of the building.• Do not locate in the garage, attic, crawl space, or underneath deck.Locating the Exhaust Weatherhood• At least 460mm (18") above ground or above the depth of expected snow accumulation• At least 1m (3’) away from the corner of the building• Not near a gas meter, electric meter or a walkway where fog or ice could create a hazard• Do not locate in a garage, workshop or other unheated spaceInstalling the ducting to the weatherhoodsA well designed and installed ducting system will allow the ERV to operate at its maximumefficiency. The inner liner of the flexible insulated duct must be secured to the sleeve of theweatherhood (as close to the outside as possible) and to the appropriate duct connection onthe ERV. The insulation should remain full and not crushed. The outer liner, which acts as avapor barrier, must be completely sealed to the outer wall and the ERV using tape and/orcaulking. A good bead of high quality caulking (preferably acoustical sealant) will seal the innerflexible duct to both the ERV duct connection and the weatherhood prior to securing them. Tominimize airflow restriction, the flexible insulated duct that connects the two outsideweatherhoods to the ERV should be stretched tightly and be as short as possible. Twisting or folding the duct will severely restrict airflow.See “Installation Diagram Examples” for installation examples.1 Using the duct connection ofthe outside hood, outline theintake & exhaust holes to becut. The holes should be slightlylarger than the duct connectionto allow for the thickness of theinsulated flexible duct. Cut ahole for both the intake andexhaust hoods.3 Push the hood into the openingand then attach the hood to theoutside wall with mountingscrews.Repeat the installationprocedure for both the supplyand exhaust hoods.2 Pull the insulated flexible ductthrough the opening until it iswell extended and straight.Slide the duct’s inner vinylsleeve over the hood ductconnection and secure. Pull theinsulation over the duct andpull the vapor barrier over thesleeve. Secure withappropriate tape or sealant.4 Using a caulking gun, sealaround both hoods to preventany leaks.Steps for hood installation:36" (1m)min.INTAKEOUTSIDE CORNER INSIDE CORNEREXHAUST18" (460mm) min. 18" (460mm) min.6' (2m)min.36” (1m)min.
