Chimney Requirements Do not connect Nova to a chimney flue serving any other appliance or use in conjunction with any air distribution ductwork, unless specifically approved. This room heater must be connected to: 1. A 6” (150 mm) diameter, UL 103 HT chimney, from a single manufacturer OR 2. A code approved masonry chimney with a flue liner. Standard Chimney Arrangement A. Chimney termination 15’/33’ (4.5/10m) min/max height B. Roof penetration C. Chimney sections D. Ceiling penetration E.
Chimney Connector Requirements Chimney connector is required from the flue collar of the stove to the factory-built chimney or masonry chimney. The chimney connector must be 6” (152mm) diameter and a minimum 24 gauge black steel. Aluminum or galvanized steel is not allowed – these materials cannot withstand the flue temperatures and may give off toxic fumes when heated.
Chimney Termination Requirements Must have an approved cap (to prevent water from entering) Must not be located where it will become plugged by snow or other material Must terminate at least 3' (914mm) above the roof and at least 2' (610mm) above any portion of the roof within 10' (3.
Special Installation: Exterior Factory-Built Chimney Nova may be used in conjunction with an exterior factory built chimney provided that the chimney meets UL 103 HT requirements. Special care must be taken regarding the wall thimble, or penetration from the chimney connector pipe to the exterior chimney, if the wall thimble must pass through an exterior wall.
Special Installation: Masonry Chimney Nova may be used in conjunction with a masonry chimney provided all installation instructions are followed. We strongly recommend a full reline when installing the Nova in a masonry chimney. If the chimney does not have a clay tile liner, a full reline is required. The chimney must be clean, undamaged, and meet all local building codes.
Special Installation: Masonry Fireplace Nova may be used in conjunction with a masonry fireplace provided all installation instructions are followed. The entire fireplace must be clean, undamaged, and meet all local building codes. This installation requires a full reline. The liner must be stainless steel chimney connector or flexible vent pipe. Follow the liner manufacturer’s instructions for installation and support.
Installing the Brick and Ceramic Fiberboard After installing your Nova and before burning your first fire, there are a few final steps. Nova has internal bricks designed to maintain a smooth even heating. The bricks are a great insulator that absord heat from the fire, hold the heat, and slowly release it. Unpack the bricks and ceramic fiberboard that accompany your Nova. The ceramic fiberboard and bricks received with your stove may not have the corresponding numbers in steps below.
2. Next, the bricks should be installed on the interior of the ceramic fiberboard as illustrated below. Step 3 below shows the bricks retainer pieces. It may be easiest to install the brick retainer pieces in Step 3 prior to the second row of bricks.
3. Finally, the T-bar retainer pieces (2) should be installed on both sides in order to keep the bricks in place. 4. It is normal to have small gaps between the bricks upon completion. The bricks can be shifted towards the rear of the fire box.
Catalytic Combustor Please refer to the instructions that accompanied your catalytic combustor for installation instructions. Your stove should not be used without installing the catalytic combustor properly. Ash Retainer Your Nova comes standard with an ash retainer than can be used to extend the number of burns between emptying the ash, if desired. The 6” leg L-shaped ash retainer is placed directly on the brick on the firebox floor. This allows for a lip in front of the glass to retain ash.
Stove Top Thermometer The stove top thermometer is an accessory that can be used to help determine when to close the catalytic combustor bypass on your Nova. The thermometer should be placed on the stove top, 8” from the front of the stove and 11.25” from the side of the stove. For most uses, when the thermometer reads “ENGAGE CATALYST”, the catalytic combustor bypass can be swung closed (to the rear of the stove).

How Nova Works Nova is a whole lot easier to use than any wood stove you have ever used. Gone are the days of using dampers. Gone is keeping the door open forever in order to start the stove, spilling smoke into the room. Instead, Nova is a simple and easy to use wood stove that provides great heat and a beautiful view of your fire through a massive front glass. Just build a fire and sit back and enjoy your beautiful fire.
Reloading When reloading, if there is a large coal bed (glowing red coals, covering the entire bottom, at least an inch deep), there is no need to use kindling or newspaper. To reload, open the bypass, wait 10-15 seconds for the exhaust gases to re-stabilize, and slowly open the front door. Fill the firebox chamber with logs, taking care not to stack the logs too close or touching the front door glass. Then simply shut the door and walk away.
Regular Maintenance and Troubleshooting Woodstoves, even those as clean as Nova, must be cleaned frequently because soot, ash, and creosote may accumulate. Please follow a routine maintenance schedule as suggested here. Glass The glass will accumulate some soot through the course of regular burning. More soot will accumulate during slow burns than during hotter burns. Sooting is worse with unseasoned or resinous woods. To clean the glass, the unit should be allowed to cool.
Catalytic Combustor This wood heater contains a catalytic combustor to help achieve a clean burn. It is important to periodically monitor the operation of the catalytic combustor to ensure it is properly functioning, and not clogged. A clogged or otherwise non-functioning combustor will result in poor performance, smoke leakage, a loss of heating efficiency, and an increase in creosote and emissions. Your catalytic combustor should be visually inspected at least monthly to check its condition.
Monthly Maintenance Creosote – Formation and Need for Removal When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire.
Annual Maintenance Exterior Paint To fix areas on the exterior of the stove that have been scratched or dinged, simply use aerosol stove paint. Color match paint can be ordered directly from MF Fire. Simply email us at info@mffire.com and tell us the color you need, and we will ship it right out to you. Paint should only ever be applied while the stove is cool. Allow the paint at least one hour to cool. After applying the paint, the newly painted area may appear darker than original until it is cured.
Catalytic Combustor Replacement If you suspect that your catalytic combustor is not working, the catalytic combustor should be removed and inspected to identify the source of the problem. CAUTION: DO NOT OPERATE THE NOVA WOOD HEATER WITH CATALYTIC COMBUSTOR REMOVED! To access the catalytic combustor, first remove the chimney connector pipe from the stove. The catalytic combustor may then be removed from its holder by reaching into the back of the stove.
