The IronStrike ML300GL Montlake 300 Wood Insert is the largest and most powerful model in the Montlake series, designed to transform an existing fireplace into a highly efficient whole-home heating system. Featuring an expansive 3.0 cubic foot firebox that accommodates logs up to 21 inches long, this EPA-certified wood-burning insert produces up to 100,000 BTUs of heat and can warm spaces ranging from 2,000 to 3,000 square feet. Its tall viewing area and large ceramic glass window provide a stunning view of the fire, creating a beautiful focal point while delivering exceptional heating performance.
At the heart of the Montlake 300 is IronStrike’s advanced Thermal Fin heat exchanger, which creates 32% more heat-transfer surface area than traditional insert designs. This innovative technology helps maximize heat output while improving overall efficiency and reducing fuel consumption. An integrated air-boost timer automatically adjusts airflow during startup and reloading for easier operation, while the high-density firebrick lining stores and radiates heat long after the fire has burned down. The built-in air wash system continuously helps keep the ceramic glass clean, ensuring an unobstructed view of the flames.
Constructed from precision-cut heavy-gauge steel for long-lasting durability, the IronStrike ML300GL includes a standard 150 CFM variable-speed blower that efficiently circulates warmth throughout the home. Homeowners can personalize the insert with optional brushed nickel or nickel door trim, choose from multiple surround panel sizes, and select either a steel or cast-iron warming top to match their décor. EPA-certified, Washington State-approved, and qualifying for the 30% Federal Tax Credit, the Montlake 300 delivers powerful heating performance, premium craftsmanship, and long-term value backed by a Limited Lifetime Warranty.

I would highly recommend Ridge Flame to anyone. My wife and I spent weeks researching different options, and many local retailers were offering limited selections at much higher prices. After contacting Ridge Flame, we spoke with Michael, who took the time to understand exactly what we were looking for and guided us through the entire process. He answered all of our questions, helped us choose the right model. The customer service was outstanding, the pricing was competitive, and the overall experience exceeded our expectations. We couldn’t be happier with our purchase. Thanks again!
