2.0 Operation

2.1 Before you start firing

For Use with Solid Wood Fuel Only. Use of inappropriate fuel can result in the release of toxi c
fumes. Do Not Overfire, If Heater or Chimney Connector
Glows You Are Overfiring. Inspect and Clean Chimney Frequently. Under Certain
Conditions of creosote buildup may occur. To reduce the risk of smoke and flame spillage,
operate only with door fully closed.
Hot while in operation. Keep children, clothing and furniture away. Contact may cause
skin burns.
CAUTION
Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid or
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 21 inches (53 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 season
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 lever, lighting techniques and loading intervals will depend on
chimney draft, the fuel used, the heat required and so on. Some basic techniques are outlined
below.

In principle
Your stove has three air supplies:
Primary air is controlled by the air controller beneath the door. The air from here passes through
internal channels and eventually washes at high speed down the back face of the door glass. This
super-heated air helps with the combustion of volatile gases produced by the fire.
Secondary air is supplied to the top of the fire through holes in the tubes under the lower baffle.
This effectively burns off other residual gases, making for very clean emissions. This air supply
is constant and cannot be varied.
Pilot air is supplied to the firebed through a hole placed behind the front grate. This air will activate
the embers. This air supply is factory set and cannot be varied.

2.2 Lighting and loading intervals

When first lighting the stove, a large volume of air is needed. When the stove is cold, you should
leave the door open an inch or two for the first few minutes and open the primary air
similar
supply completely. While the door is open, do not leave the stove unattended.
To establish a reasonable bed of ash on the firebox floor, you should use 5-6 inches thickness
(4-6 pound) of dry kindling at the initial lighting. Always maintain a 1-1,5 inch (2-3 cm) layer of
ash on the floor of the combustion chamber at all other times.
1. A layer of embers will form rapidly if the stove is lit with fire lighters or 7-10 rolled up sheets
of newspaper, underneath roughly 4-5 lb. of dry kindling.
2. Light the fire.
3. Fully open the air controller so that primary air can enter the firebox.
4. After the paper/fire lighters have caught fire, leave the fire door ajar about 1 inch, so that the
chimney draws well.
5. After 5-10 minutes the chimney draft should be established, at this point close the fire door.
If all the necessary conditions are met, a nice layer of embers will start to accumulate after
another 15-20 minutes.
6. Refuelling of your stove should be done while there are still glowing embers in the bed. Spread
the embers across the bottom, but concentrated mostly towards the front of the stove.
7. Place 2-3 pieces of fuel weighing roughly 4-6 lb. across the embers in one layer, with spacing
of roughly 1 inch between the pieces of wood.
8. When the primary air supply is open all the way and the door is closed, the new fuel will ignite
in a few minutes.
9. Once the new fuel has taken, adjust the primary air amount to the desired setting; optimal
combustion will continue until glowing embers are produced.
10. A new charge of wood can be added by repeating steps 6 & 7.
Do not support the fuel with use of grates, andirons or other methods.
