Duluth Forge Dual Fuel Ventless Fireplace Insert
The Duluth Forge FDI32R uses ventless dual-fuel technology, letting you run on natural gas or propane. With 32,000 BTU, it heats up to about 1,500 sq. ft. and does not require an outside vent or chimney. This makes it a strong choice for medium-to-large living spaces where hard ducting is impractical.

Best for: Homeowners seeking high heat output with dual-fuel flexibility in ventless installations. It’s well suited for living rooms or open-concept spaces up to 1,500 sq. ft.
Limitation: Being ventless means room ventilation is important; ensure proper room size and CO detectors are in place. The unit’s size and heat output may be overkill for smaller spaces.

Its 13.5 x 13.5-inch footprint fits many standard rooftop or wall terminations and helps safeguard the vent system for gas fireplaces and stoves.

Best for: Rooms where a three-sided flame view adds value and flexibility to installation. It’s a balanced option for spaces around 1,000–1,200 sq. ft. where ambiance matters as much as heat.
Caution: The three-sided flame effect requires sufficient viewing angles; position the stove to maximize flame visibility from multiple seating areas.

Buying Guide: Key Considerations For Gas Fireplace Side Vent Installations
- Vent Type: Ventless vs. direct-vent options affect room ventilation and installation. Ventless units heat spaces quickly but require proper air exchange and detectors. Direct-vent or side-vent solutions limit indoor air mixing and may require ducting considerations.
- BTU Output And Room Size: Choose BTU based on room square footage. Higher BTU units heat larger areas but may feel too warm in small spaces.
- Fuel Type: Dual-fuel models offer natural gas or propane flexibility. Consider your available gas supply, fuel cost, and existing hookups.
- Installation Footprint: Measure clearance, mantle height, and wall space. Slim profiles suit compact interiors, while three-sided views or double doors influence placement and aesthetics.
- Remote Control And Controls: LCD remotes simplify operation, but verify compatibility with your gas line and pilot system. A standing pilot can affect startup procedures.
- Maintenance And Accessibility: Look for models with accessible logs and a simple cleaning path. Vent covers should be kept free of debris to maintain efficiency.
- Safety: Install CO detectors and ensure proper venting. Follow manufacturer instructions for ventless use to avoid overheating or improper combustion.
