MF Fire
MF Fire builds EPA-certified steel wood stoves in two sizes — the Nova C and the larger Nova 2X — and then lets you decide what they become. The same firebox can stand on a low leg kit, sit on a tall Tower pedestal at eye level, rest on a 48-inch steel bench, or slide into an existing masonry fireplace with a surround kit. Big glass, convertible top or rear venting, and EPA-tested efficiencies of 71% (Nova C) and 78% (Nova 2X) HHV mean you get a modern clean-burning heater that still looks like a fire, not an appliance.
OffGrid Horizon is an authorized MF Fire dealer. You will find the complete Nova line here: fireboxes in Satin Black and Charcoal, Tower bases, the Nova Series Bench, insert surround kits, leg kits, room blower fans, cast iron ash lips, make-up air kits, reduced clearance kits and additional stocked door finishes. Wood stove installations live or die on clearances, floor protection and venting, so if you are unsure which part numbers your build needs, call us at (302) 496-3554 before you order and we will match the configuration with you.

MF Fire FAQ
Should I choose the Nova C or the Nova 2X?
The Nova C has a 1.7 cu ft firebox for 18-inch logs and is rated to heat up to about 1,500 sq ft. The Nova 2X has a 2.4 cu ft firebox for 22-inch logs, is rated to heat up to about 2,500 sq ft and includes MF Fire's AirX timed air control.
Which base do I need?
Nova fireboxes ship without a base. Choose 3, 6 or 9 inch legs, a Tower base, the Nova Series Bench, or an insert surround kit for an existing masonry fireplace. With 3 inch legs MF Fire requires a UL 1618 Type 2 thermal hearth pad; with 9 inch legs a Type 1 ember-only pad is enough.
Can a Nova stove go into an existing fireplace?
Yes. With the Nova C or Nova 2X insert surround kit, the firebox installs into an existing masonry fireplace.
Are Nova stoves approved for mobile homes?
No. MF Fire Nova stoves are not approved for mobile or manufactured home installation.
What warranty comes with an MF Fire stove?
The firebox welds carry MF Fire's Limited Lifetime warranty, defined by MF Fire as up to 7 years. Register your stove with MF Fire after purchase to activate coverage.
