It should be placed on top of the rear (fixed) baffle section and secured into position against the  upstanding cast lugs.
  • Page 7: Draft Conditions

    2.1 Lighting and refuelling intervals Kindling (dry sticks) requires a large volume of air for quick combustion. When lighting the stove from cold it will help to keep the main door ajar (-3cms) for the first few minutes. The primary and secondary air supplies should be fully open during lighting. 1.

Place three pieces of fuel weighing roughly 0.7 kg and measuring about 30 cm in length across the embers in one layer, with spa- cing of roughly 1 cm between the pieces of wood.
  • Page 11 The stove door should normally be opened gently the first  - 3 centimetres, then you should wait until the pressure has equalised before opening the door all the way. This technique will prevent smoke from getting out, particularly when there is a poor draught. The stove door should never be opened when the stove is being fired vigorously.

  • Page 14: Alternative Fuel Types

    4.0 Alternative fuel types Your new Morsø stove is EN-approved for burning wood. However, the stove is capable of burning other solid fuels as manufactured smokeless coal or good quality anthracite (stove nuts). If you fire your stove with any fuel other than wood, it may help to use coal insert/fuel economisers (available for most models), which simply fit into the left and right sides of the firebox.
