Due to the broad range of installation and operational conditions, consideration must be given for the possibility of condensation forming on the unit or connecting ducting. Objects below the installation may be exposed to condensate. • At least 3' (1 m) away from the corner of the building* • At least 3’ away from 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 weather hood, its outside perimeter must be sealed with exterior caulking. * Local code may require greater distances. Intake Weather Hood Requirements • Should be located upstream (if there are prevailing winds) from the exhaust outlet • At least 6' (2 m) from the exhaust weather hood * • At least 6' (2 m) away from dryer vents and air handler exhaust (medium or high efficiency furnaces)* • A minimum of at least 6' (2 m) from driveways, oil fill pipes, gas meters, or garbage containers, swimming pools* • At least 18" (457mm) above the ground, or above the depth of expected snow accumulation* • At least 3' (1 m) from the inside/outside corner of the building* • Do not locate in a garage, attic or crawl space * Local code may require greater distances.

Always try to keep duct runs as short and straight as possible. See Installation Diagrams for various installation options. The inner and outer liners of the flexible insulated duct must be clamped to the sleeve of the weather hoods (as close to the outside as possible) and the appropriate port on the HRV. 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 silicone sealant) will seal the inner flexible duct to both the HRV port and the weather hood prior to clamping with a large zip tie. To minimize air flow restriction, the flexible insulated duct that connects the two outside weather hoods to the HRV 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 hoods and the HRV. WARNING Include a short length of fabric flex duct or other non-metallic connector in this hard ducted line in order to keep the HRV separately grounded (electrically) from the air handler. This will avoid a possible shock hazard to service people if a short to ground develops in one of the devices. Stale Air Exhaust System The stale air exhaust system is accomplished by the positive pressure created in the furnace ducting. The air handler blower must be running for this system to be effective. Drain Connection (HRV Only) During a defrost cycle, the HRV may produce some condensation. This water should flow into a nearby drain, or be taken away by a condensate pump. The HRV cabinet has prepunched holes for the drain (see below). Insert the drain spout through the hole in the drain pan. Do not forget the “O ring” which seals each spout to the pan. REMEMBER TO HAND TIGHTEN ONLY the washer and lock nut which hold the drain spout in place. Construct a P-Trap using the plastic tee connector. Cut two lengths of hose and connect each piece to an end of the “T” fitting, then connect the other ends to the two drain spouts. Position the "T" fitting to point upward, andconnect the drain line. Tape or fasten base to avoid any kinks. This creates a “trap” which will hold some condensate and prevent odours from being drawn up the hose and into the fresh air supply of the HRV. CAUTION The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point.
