Installation
The FIREGAS range hood is designed for under-cabinet mounting and offers both ducted and ductless (recirculating) ventilation options. Refer to the included 'Installation Manual' and 'Installation Drawing' for detailed, step-by-step instructions and diagrams.
Ventilation Modes
This range hood is convertible and supports two primary ventilation modes:
- Ducted Mode: Smoke and odors are vented outside through a duct pipe. The unit has a 7-inch round top exhaust port and a 9.92"W x 3.07"H rectangular rear exhaust port.
- Ductless (Recirculation) Mode: Smoke and odors are filtered through an optional charcoal filter (not included, sold separately as FGS-TF39-LW) and recirculated back into the kitchen. The included recirculation sheet is used for this mode.

Electrical Connection
The range hood is hardwired and does not come with a plug. An electrical box (FGS-TF39-DYX, sold separately) may be required for connection. Ensure all wiring is done by a qualified electrician and complies with local electrical codes.
- Pry open the designated hole for wiring.
- Install the black rubber ring and extend the wires from inside the range hood through the hole to the outside.
- Connect the wires on the outside of the range hood, matching colors appropriately.
- Secure the wire connections with white wire caps and tools.

Maintenance
Regular maintenance ensures optimal performance and longevity of your range hood.
Cleaning the Aluminum Filters
The multi-layer aluminum filters capture grease and oil. They should be cleaned regularly, typically every 3-6 months depending on cooking frequency, to maintain efficient airflow.
- Ensure the range hood is turned off and unplugged from power.
- Locate the buckle or latch mechanism holding the filter in place.
- Open the buckle and carefully slide the aluminum filter out in a parallel motion.
- Clean the filters using warm soapy water or a dishwasher. For stubborn grease, a degreasing agent can be used.
- Rinse thoroughly and allow the filters to dry completely before re-installing.
- Slide the dry filter back into its slot and secure the buckle.

General Cleaning
Wipe the exterior surfaces of the range hood with a soft cloth dampened with mild soap and water. Do not use abrasive cleaners, steel wool, or harsh chemicals, as these can damage the stainless steel finish.
