MF Nova Wood Burning Stove Insert

The Nova Insert is engineered to fit over 85% of existing masonry fireplaces. The standard Nova requires a minimum fireplace opening of 25" H x 30" W x 16" D, while the larger Nova 2 requires 28" H x 33" W x 16" D. Measure your fireplace opening's height, width, and depth before ordering. If your opening falls short by an inch or two, a qualified mason or hearth professional can often modify the firebox to accommodate the insert. Both models offer top and rear vent compatibility for added installation flexibility.

The Nova is the compact model with a 1.7 cu. ft. firebox, accepts 18" logs, produces up to 50,000 BTU/hr, and heats up to 1,500 sq. ft. — ideal for smaller fireplaces and rooms. The Nova 2 features a larger 2.4 cu. ft. firebox, accepts 22" logs, generates up to 75,000 BTU/hr, heats up to 2,500 sq. ft., and qualifies for the 26% federal biomass tax credit. Choose based on your fireplace opening dimensions and the square footage you need to heat.

No — that's one of the Nova's signature advantages. The stove uses a passive, self-regulating combustion design that automatically optimizes airflow for clean, efficient burning. There are no air levers, dampers, or burn-rate controls to manage. You simply load the firebox, light the fire, and let it burn. This makes the Nova one of the most user-friendly wood inserts on the market, especially for first-time wood stove owners.

Yes. Both the Nova and Nova 2 are 2020 EPA certified with emissions as low as 1.9 g/hr — well below the 2.5 g/hr threshold. The Nova 2 specifically qualifies for the 26% federal tax credit under Section 25(D) for high-efficiency biomass heating appliances (75% HHV efficiency or higher), which can save you over $1,000 on the purchase and installation.

The Nova Insert is compatible with both top and rear venting configurations and requires a properly sized, code-compliant chimney liner — typically a stainless steel flex liner sized to match the insert's flue collar. Existing masonry chimneys must be inspected, cleaned, and lined before installation. We recommend hiring a CSIA Certified Chimney Sweep for inspection, lining, and installation to ensure safe operation and code compliance.

The Nova Insert requires a minimum 36" front clearance from combustible materials such as drapes, furniture, doors, or wood trim that could swing within that zone. Non-combustible floor protection must extend around the front, sides, and rear of the stove per the listed clearance specifications in the owner's manual. Floor protection must be made of non-combustible material at least 0.018" (0.45 mm) thick with the specified minimum R-value. Always consult the installation manual and your local code authority before installation.

MF Fire backs the Nova Insert with a limited lifetime warranty on the stove body for the original purchaser. The room blower fan carries a 1-year limited warranty, and the catalytic combustor is covered by a 5-year limited warranty. Exclusions include paint, gaskets, glass, fasteners, and fire bricks, as well as damage from misuse, improper installation, over-firing, or normal wear. Register your stove at mffire.com/myproduct with photos of your installation to activate coverage, and report any warranty issues within 30 days of discovery.
