Installing Air Ducts

A well designed and installed ducting system will allow theHRV/ERV to operate at its maximum efficiency.

Always try to keep duct runs as short and straight as possible.See Installation Diagrams for various instal- lation options.

Outside Weatherhoods

The fixed covered hoods have a built-in bird screen with a 1/4" (6 mm) mesh to prevent foreign objects from entering the ductwork.

Locating the Intake Weatherhood

Should be located upstream (if there are prevail- ing winds) from the exhaust outlet

At least 6' (2 m) from the exhaust weatherhood

At least 6' (2 m) away from dryer vents and fur- n a c e e x h a u s t ( m e d i u m o r h i g h e f f i c i e n c y furnaces)

A minimum of at least 6' (2 m) from driveways, oil fill pipes, gas meters, or garbage containers

At least 18" (457 mm) above the ground, or above the depth of expected snow accumulation

At least 3' (1 m) from the corner of the building

Do not locate in a garage, attic or crawl space

Locating the Exhaust Weatherhood

At least 6' (2 m) from the ventilation air intake

At least 18" (457 mm) above ground or above the depth of expected snow accumulation

At least 3' (1 m) 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

Not into a garage, workshop or other unheated space

When installing the weatherhood, its outside perimeter must be sealed with exterior caulking.

Installing the ducting from the weatherhoods to the HRV/ERV

The inner and outer liners of the flexible insulated duct must be clamped to the sleeve of the weatherhoods (as close to the outside as possible) and the appropri- ate port on the HRV/ERV. It is very important that the fresh air intake line be given special attention to make sure it is well sealed. A good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to both the HRV/ERV port and the weatherhood prior to clamping.

To minimize air flow restriction, the flexible insulated duct that connects the two outside weatherhoods to the HRV/ERV should be stretched tightly and be as

short as possible.

Twisting or folding the duct will severely restrict air flow. See below for the recommended connection of flexible insulated ducts to the the outside weather-

Warmside Ducting

To maximize airflow in the ductwork system, all ducts should be kept short and have as few bends or elbows as possible. Forty-five degree elbows are preferred to 90° elbows. Use “Y” tees instead of 90° elbows when- ever possible.

All duct joints must be fastened with screws, rivets or duct sealant and wrapped with a quality duct tape to prevent leakage. We recommend aluminum foil duct tape.Galvanized ducting from the HRV/ERV to the liv- ing areas in the house is recommended whenever possible, although flexible duct can be used in moder- ation if necessary.To avoid possible noise transfer through the ductwork system, a short length (approxi- mately 12 " or 300 mm) of non-metallic flexible insulated duct should be connected between the HRV/ERV and the supply/ exhaust ductwork system.

T h e m a i n s u p p l y a n d r e t u r n l i n e s t o / f r o m t h e HRV/ERV must be 6 inches (150 mm) minimum. Branch lines to the individual rooms may be as small as 4 inches (100 mm), but 5 inch (125 mm) lines are preferred .

All ducts running through attics and unheated spaces must be sealed and insulated to code.
