Tips for installing your new unit:

  • Although the WoodMaster Biomass Mini Boiler is compact, be sure to leave room for the pellet hopper and auger system, and comfortable maintenance and cleaning.
  • To ensure that your storage room is properly ventilated for the combustion process, we recommend a vent that is at least 20 sq. in.



Be sure to disconnect any power and allow your unit time to cool before cleaning the heat exchanger tubes and emptying the ash box. Easy access to the heat exchanging tubes is made by taking the top door and cover off of the furnace. When cleaning the heat exchanger tubes carefully work around the ceramic insulation to ensure there is no damage. The Mini Boiler has an extra large ash box (holding approximately 1-2 weeks worth of ashes) which allow for longer intervals between changes, but should be checked and emptied regularly. Daily maintenance of the firebox is taken care of by the Air Cleaning system, however, the firebox should be taken out post heating season and thoroughly cleaned to maximize performance.
