Duluth Forge 9-Log Ventless Dual Fuel Inset
Duluth Forge’s 9-Log ventless dual-fuel insert delivers up to 32,000 BTU and can heat spaces up to about 1,500 square feet. Its ventless design means no chimney or external ducting is required, while efficiency reaches 99.9%. A remote with LCD control lets you operate the natural gas or propane burner from a distance, and a standing pilot ensures quick startup. The nine hand-painted ceramic logs create a natural-looking flame, complemented by a mesh screen for safety and aesthetics. Manual flame adjustment allows fine-tuning of flame intensity to suit different rooms and moods.
Key advantages include dual-fuel flexibility, strong heat output, and a realistic fire display. The larger log set contributes to a robust visual flame.

Buying Guide
Key purchase considerations
When evaluating a gas fireplace insert with a blower, start with the room size and desired heat coverage. BTU ratings indicate potential heat output, but real-world performance depends on ceiling height, insulation, and layout. For spaces around 1,300–1,500 square feet, higher BTU units or those paired with effective fans tend to perform best. Consider whether you prefer a single large flame or a multi-log display for ambiance alongside warmth.
Ventless vs. vented and fuel options
Ventless (vent-free) inserts offer simpler installation and can heat without a chimney, which is attractive in retrofit projects. However, ensure proper room ventilation and local codes. Dual-fuel models provide flexibility to use natural gas or propane based on availability or price. Propane can be more economical in off-grid settings but may require a larger fuel tank, while natural gas requires a fixed gas line. Choose based on your home’s gas infrastructure and long-term maintenance considerations.
Heat distribution and blower considerations
Blower kits and built-in fans help move warm air throughout the room for even heating. If your fireplace insert lacks an integrated blower, you can often add an aftermarket solution to improve circulation. When evaluating products, look for a model with a dedicated remote or thermostat; this enables automatic cycling and consistent comfort without manual adjustments. If heat distribution is a priority, confirm compatibility with a blower accessory and the noise level of any fan.
Log realism, finish, and aesthetics
Realistic log sets, ember beds, and decorative fronts contribute to the fireplace’s ambiance. Look for hand-painted logs and brick liners or screens that match your interior style, whether traditional or contemporary. A mesh screen not only adds safety but also enhances the overall visual appeal. Balance aesthetics with performance to ensure the insert complements your room design while delivering dependable warmth.
Controls, thermostat, and remote features
Remote control with LCD screens, built-in thermostats, and manual flame adjustments offer convenient operation. A thermostat mode helps maintain a preferred temperature by cycling the flame on and off, which can improve energy efficiency. For larger living spaces, a robust remote control and a responsive thermostat contribute to a more comfortable experience without constant manual monitoring.
Installation, safety, and maintenance
Installations vary from simple insert swaps to zero-clearance configurations. Certifications and local codes dictate clearances, venting requirements, and electrical connections. Routine maintenance includes checking gas connections, cleaning flame ports, and inspecting logs for cracking or wear. If you’re unsure about installation or venting in your home, consult a professional installer to ensure safety and optimal performance.
Warranty and long-term value
Warranty terms differ between brands and models. When evaluating value, consider not only initial cost but also the availability of replacement parts, remote controls, and log sets. A model with readily available service options and a durable log set tends to offer lower maintenance costs over time, preserving heat efficiency and aesthetics for years to come.
