  • Use seasoned wood that has been stored in a dry place for two years only.
  • Start fire wit by-pass damper in open position. Wait until combustor has reached its operation temperature – then close the lid.
  • Start a fast fire. This not only helps combustor reaching operation temperature soon, but also generates the draft that is necessary to overcome the resistance caused by the combustor.
  • Piecemeal refueling. Don’t add big, add small – but regularly and avoid combustor from cooling below its operating temperature. Heat emission is a function of surface area, surface material, and difference in temperature between stove and  air. Creating a bigger fire will influence surface temperature, but will certainly not effect surface area and material of the stove. This means that by making a larger fire, a substantial portion of the additional heat will not go to the room, but will be lost as hot flue gas; heating outside air instead of keeping energy inside. It’s thus a pure waste of fuel – and it may finally destroy the catalyst (overheating; see page 12) as well as the stove itself.
  • Make sure ash box and fire doors are closed properly. Replace gaskets if necessary. The additional air may cause overheating.
  • Never burn rubbish, plywood, plastic – or coal!
  • Close by-pass damper after having reached operating temperature. This will be achieved after 20 to 30 minutes.
  • Don’t overheat! Avoid temperature rising above 950C (1,740F) since at this temperature material properties will alter and thus render combustor impotent. Open the (manual) bypass damper and wait until temperature has fallen to 550C (1,020F) before re-starting your Firecat®.
