• Fuel Options: cordwood, wood chips or wood pellets
• Lambda sensor analyzes levels in the stack and sends it to the eco manager
• Variable speed fan adjusts the air intake to reach the optimal burn for efficiency, emissions and prolonged product life
• Eco manager pulls the system together—from the lambda sensor to the draft inducer—enabling user-friendly maintenance
• Optional self-ignition is programmable by time or water temperature
• Self-cleaning heat exchangers assist in maintaining money-saving efficiency levels—with less maintenance
• Wood gasification technology provides excellent combustion at high temperatures for better efficiency and fewer emissions
• Large ash chamber makes ash cleanup quick and easy
• Smoke extraction directs remaining smoke to the flue when you open the loading doors
• Easily converts from one fuel to another once installed. This gives you more options with less time
• Solar capable which is another option to save even more money and use less fuel

Maintenance

Cleaning the Furnace

• Disconnect the power source prior to cleaning. Never clean your furnace during operation.
• Wait for the furnace to cool before cleaning the furnace.
• Correctly dispose of the ashes in a sealed metal container away from flammable materials.
• Cleaning intervals will vary depending on the quality of the fuel being used.

Cleaning Intervals

• Air Feed: As required following visual inspections
• Ash Chamber: Every 2 weeks
• Heat Exchanger: Automatic

Cleaning the Air Passages

Before firing the furnace, check that all the air openings above the grate are free of ash. It may be necessary to use the ash scraper to open them. Regularly check that the air openings are not clogged with tar. Manually clean the turbulators every 4000 hours. If necessary scrape the primary air feed openings inside the firebox with the ash scraper to maintain air flow.

Cleaning the Ash Chamber

• Check that the furnace is not operational and is cool
• Open the outer enclosure door
• Open the ash chamber door
• Push the ash tray onto the bottom door frame
• Use the ash scraper to carefully pull the ash onto the ash tray. Leave approximately .5 in of ash in the entire bottom of ash chamber to extend the life of the refractory

Owner’s Resources

Safety:

• All installation and operations must follow STATE and LOCAL CODES for wiring, plumbing, and fi ring of this unit. These CODES may differ from the owner's manual. Installation must be performed by a Qualified Installer.
• Read and follow the directions carefully. Retain the owner's manual for as long as you own your WoodMaster furnace.
• Your Flex fuel must be installed by a professional and should follow all local, state and federal laws and regulations. All installations must be pre approved by WoodMaster. Any use of an unapproved installation may result in a voided warranty.

Best Burn Practices:

1. Read and follow all operating instructions supplied by the manufacturer.
2. FUEL USED: Only those listed fuels recommended by the manufacturer of your unit. Never use the following: trash, plastics, gasoline, rubber, naphtha, household garbage, material treated with petroleum products (particle board, railroad ties and pressure treated wood), leaves, paper products, and cardboard.
3. LOADING FUEL: For a more efficient burn, pay careful attention to loading times and amounts. Follow the manufacturer's written instructions for recommended loading times and amounts.
4. STARTERS: Do not use lighter fluids, gasoline, or chemicals.
5. LOCATION: It is recommended that the unit be located with due consideration to the prevailing wind direction.
• Furnace should be located no less than 100 feet from any residence not served by the furnace.
• If located within 100 feet to 300 feet to any residence not served by the furnace, it is recommended that the stack be at least 2 feet higher than the peak of that residence.
