5. When the chimney is warm after about
5-10 minutes, the door should be closed.
A suitable layer of ember will be formed
after about 15-20 minutes.
6. When ready to reload, use a poker to
spread the embers across the firebox floor,
bringing plenty towards the front of the
stove.
7. Lay three pieces of wood onto the embers.
Leave half an inch or more between each
piece.
Max. fuelload 1,2 pounds/h.
8. Close the door. Leave the primary air
supply fully open.
If it does not light, leave the door slightly
ajar to allow the necessary amount of air
in to ignite the wood.
Close the door again once the wood has
kindled.
9. After a few minutes, adjust the primary air
supply to suit your heating requirements.
Make sure that there is always enough air
to sustain clear, enduring flames when you
reduce the amount of combustion air, and
afterwards.

10. For refueling, add a layer of wood while
there are still plenty of live embers, repeat
steps 6-9.
Do not for any reason attempt to increase the firing of your heater by altering the air
control adjustment range outlined in these directions.
Warning: Fireplace stoves must never be left unattended with the door open.
If the door is left partly open, gas and flame may be drawn out of the fireplace stove
opening, creating risks from both fire and smoke. We recommend that you fit a smoke detector
in the room where the stove is installed.
DO NOT OVERFIRE THIS HEATER. Overfiring may cause a house fire, or can result in
permanent damage to the stove. If any part of the stove glows, you are overfiring.
The maximum recommended weight of wood fuel per load is 2.5 kg/h/5.5Ibs (approx 3 split logs).
Under normal firing, the average flue temperature in the stove pipe, measured 20 cm above the
stove, is approx. 300° C (550°F). The maximum flue temperature in the stove pipe must not exceed
450° C (750°F). If the flue temperature exceeds 450°C (750°F), it is considered as over firing and
may cause premature wear and tear of the stove.
To help gauge the correct running temperature of your stove, we recommend you use the Morsø
Flue Gas Thermometer (part # 62901200). The Flue Gas Thermometer magnetically attaches onto
the stove pipe approx 20 cm (8") above the stove's top plate and measures the surface temperature
of the stove pipe. Please see your authorized Morsø Dealer for availability.
Draft conditions
If smoke or fumes come out of your stove when lightning up and reloading, or if the fire simply
will not respond, a poor draft is almost certainly to blame. (In a very few cases, there may be
insufficient fresh air getting into the room - see installation advice above). Take advice from your
stove supplier on how best to upgrade your flue system to improve draft.
