2.0 Operation

2.1 Before you start firing

For use with solid wood fuel only. Do not overfire, if heater or chimney connector glows 

you are overfiring. Inspect and clean chimney frequently. Under certain conditions of use 

creosote buildup may occur rapidly. Because of risk of smoke and flame spillage, operate 

only with door fully closed.

Caution:

Hot while in operation. Keep children, clothing and furniture away. Contact may cause 

skin burns.

Do not use chemicals or fluids to start the fire.

Do not burn garbage or flammable fluids.

Do not use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter or fluid or simi-

lar liquids to start or freshen up a fire in this heater. Keep all such liquids away from the 

heater while it is in use.

Choosing your fuel

All types of natural wood can be burned on your stove, but they must be well-seasoned and 

dry. Once the wood is cut to length, it should be split down middle - to suit the dimensions 

given below - to allow moisture to evaporate.Cut the wood to a length of max 22 inches 

(56 cm) and approx. 3 to 3.5 inches (7-8 cm) in section. If you can weigh your wood, aim for 

around 2 lbs. For correct combustion and heat output, wood fuel should contain no more 

than 20% moisture; this can easily be checked by using the Morsø Moisture Meter (part # 

62929900).

To naturally season wood fuel, stack and store it under cover in an airy location where fresh air 

can move through each piece. Some soft woods may take as little as one good summer to sea-

son whereas harder woods such as oak, maple, and elm may require seasoning up to 18 months. 

Avoid overly dry wood that is gray in color as under certain conditions it can cause performance 

problems, such as back-puffing and sluggishness. Well seasoned wood will be light to hold and 

will show signs of cracking from the center-out in the ends. If your wood spits or sizzles when 

burnt, and your stove’s door glass persistently mists up, your wood is not properly seasoned. 

Never use drift wood (from the sea), whose salt content may cause corrosion, nor construction 

wood that may have been impregnated with chemicals.

Starting the First Fire

The initial fire should be small, so that the stove paint can cure and the main plates of the 

stove can settle into position. Some fumes will be given off by the paint. Ventilate the room 

during this phase.

The setting of the air control, lighting techniques and loading intervals will depend on chim-

ney draft, the fuel used, the heat required and so on. Some basic techniques are outlined 

below.

In principle

Your stove is fitted with Primary and Secondary air inlets.

Primary Air is controlled using the lever situated under the ash lip of the stove. Moving the con-

trol lever into a downward position will open the air inlet and will allow a supply of preheated 

air to enter the firebox via the ‘airwash’ system situated inside the stove and the above glass.
