Completed installation of Venmar K7 ERV. Hung the unit from the floor joists next to the Geo unit and water heater. Disconnected the old insulated flex for the skuttle which will no longer be used and attached the flex to the intake of the ERV. Ran a new 6†flex to exhaust the ERV to the exterior of the home. Ran 2 4†uninsulated flex runs to separate areas on the return air duct to facilitate the exchange of indoor and outdoor air. Ran a condensate drain tube from the ERV unit to the floor drain. Interlocked the fan on the existing Geo unit to come on when the ERV does in order to circulate the treated air better. Run tested the new ERV for proper operation.
