Fast Efficient Heating

The WoodMaster Force 20 and 30 are powered by the Renovator Pellet Burner that operates at a high efficiency and requires little space. It is perfect for the garage, workshops, and other commercial applications.

The Renovator is designed to convert your existing fossil fuel boiler/furnace system into a Natural Energy heating system. No need to replace that old outdated system when you can just Renovate it!

The Force is a hot air heat exchanger that is powered by pellets with the Renovator. It conveniently sets up next to your existing forced air system for a simple adaptation to your ducting.

The power of pellets

Wood pellets are 100% sawdust, a by-product from furniture makers, saw, paper and other mills, and otherwise destined for landfills. The sawdust is compressed and formed into 1/4-inch diameter cylinders and packaged in 40 lb. bags.


  • Efficient heat from wood pellets that supports local economy.
  • The 20 kW Renovator unit has approximately 68,000 BTU.
  • The 30 kW Renovator unit has approximately 102,000 BTU.
  • Automatic ignition for heat on demand.
  • Air Cleaned Firepot to help keep maintenance to a minimum and retain high efficiency.
  • Easily connects to existing systems, convert your fossil fuel heat to pellets for independence from foreign oil.
  • Fully automatic PLC for user friendly operation.
  • Low maintenance, just makes life easier.
  • Compact design that easily fits into tight areas.
  • Burn back protection to keep everyone safe.


  • The Force furnace must be installed in a location that has enough space for easy cleaning and maintenance of the furnace.
  • There must be ample room for the storage hopper and auger assembly.
  • The furnace must be on a level surface that can support the weight of the unit, as well as the weight of a full pellet hopper.
  • The furnace room must have a vent to allow ample fresh air for the combustion process.
  • A vent size of at least 20 sq. in. is recommended.


Sweeping the Heat Exchanger Tubes

  • Regular cleaning of the heat exchanger tubes is made from the top by taking the top door and cover off the furnace. Ensure the furnace has had ample time to cool before cleaning the heat exchanger tubes and emptying the ash box. Dispose of ash in a metal container away from combustible materials. When cleaning the heat exchanger tubes ensure that you do not damage the ceramic insulation in the process. The Force has an extra large ash box in the bottom to help with cleaning and maintenance. The ash box should be checked and emptied regularly. The ash box can hold approx. 1 cubic feet of ash, or 1-2 weeks worth of ash.

Cleaning the Burner

  • Air cleaning is a simple process. Removal of the firepot takes only a few minutes. Always disconnect the power source first!
