Duluth Forge Gas Fireplace Insert

Yes, the zero-clearance design makes this unit ideal for retrofitting into existing masonry fireplaces or custom outdoor enclosures. Because it is ventless, you do not need to worry about existing chimney conditions, though you should always verify local building codes regarding vent-free gas appliances in your area.

No, this fireplace insert does not require an electrical connection. It operates using a manual ignition system, making it a reliable choice for outdoor spaces where running power lines might be difficult or undesirable.

Yes, the unit is built from 304-grade stainless steel, which is specifically chosen for its high resistance to rust and corrosion in outdoor environments. While it is durable, we recommend using a protective cover when the fireplace is not in use to keep the burner clean and extend the life of the finish.

This unit is designed to run on gas, but you must confirm whether your specific model is configured for Natural Gas or Liquid Propane before installation. It is critical to use the fuel type specified for your unit, as they are not interchangeable without a conversion kit.

This insert produces 24,000 BTUs, which is sufficient to provide a comfortable warmth for a standard-sized patio or outdoor seating area. It is designed more for ambiance and supplemental warmth rather than as a primary heating source for large, open spaces.

While the unit comes with emerald green glass media, you can swap it out for other fire-rated glass media if you prefer a different color or style. Just ensure that any replacement media is specifically rated for gas fireplace use and does not block the burner ports, which could affect flame performance.
