5. Installation
5.1 Mounting Options
The FIREGAS range hood can be installed in either ducted or ductless (recirculation) configurations. Ensure you select the appropriate venting method for your kitchen setup.
- Ducted Installation: Air is exhausted outside through a duct system. This requires a connection to an external vent.
- Ductless (Recirculation) Installation: Air is filtered through charcoal filters and recirculated back into the kitchen. This method is suitable when external venting is not possible.
Figure 5.1: Venting options: Top, Back, and Recirculation.
5.2 General Installation Steps
- Preparation: Ensure the installation area is clear and the power supply is disconnected. Refer to the included "Installation Drawing" for detailed measurements and mounting points.
- Mounting: Secure the range hood to the underside of your cabinet using the provided screws. Ensure it is level and firmly attached.
- Ducting (if applicable): Connect the appropriate ductwork (top or rear) to the range hood and route it to the exterior vent. Use the square to round outlet adaptor and vent cover as needed.
- Electrical Connection: Connect the range hood to a 120V power outlet.
- Filter Installation: Install the aluminum grease filters. If using in recirculation mode, install the CC170 charcoal filter as described in the Maintenance section.
