4.0 Alternative fuel types
Your new Morsø stove is EN-approved for burning wood.
However, the stove can also, e.g. when used overnight, burn alternative fuels such as bri-
quettes, petrocoke (energy coke) and furnace coke.
If you fire your stove with any fuel other than wood, it may help to use a coal insert, which
has a left part and a right part. This is an additional accessory and can be purchased from
your retailer.
4.1 Burning petrocoke
Put the coke insert (consisting of a right part and a left part) into the stove. The coke insert
ensures that the fuel will be gathered over the grate. Two front grates can optionally be used;
an extra front grate can be purchased from your retailer.
Place rolled-up sheets of newspaper (5 - 10) or 2 solid alcohol tablets in the stove with ca. 1
kg of well-dried kindling on top, and then light the entire pile. Once the wood is fully ignited,
carefully place a small piece of fuel on top, without putting out the fire. Once the fuel is glow-
ing, add more. Proceed in this manner until the entire grate is covered with glowing fuel. Both
vents must be fully open during the lighting process.
Once the bottom half of the fuel layer is glowing, you can partly shut the bottom vent. Once
the stove is hot, regulate it down to the desired level of heat emission by adjusting the bot-
tom air supply. The top air regulator must be open enough that any flames burn clearly, and
the glass window stays clean.
A pale greyish layer may be deposited on the glass when the stove is fired with petrocoke.
The entire grate must be covered with fuel in order to keep the combustion process going.
The smaller the pieces of fuel, the thinner the layer needs to be. If you have low layer thick-
ness and weak heat, it is not necessary to supply air via the top vent.
Almost no ash forms when the stove is fired with energy coke, so you will not need to re-
move the ashes as often.
Petrocoke can be added up to the top edge of the top front grate, which corresponds to
roughly 5 kg.
Storing petrocoke
Petrocoke is best stored uncovered outdoors, as the dry fuel puts out a lot of dust if it is
handled indoors. It may consequently also be a good idea to spray the fuel in the fuel pail
with a water atomiser before fuelling.
4.2 Burning coke and furnace coke
Put the coal insert (consisting of a left part and a right part) in the stove.
It is necessary to use two front grates when burning coke. An extra front grate can be pur-
chased from your retailer.
When you are burning coke, the top vent must be fully closed and the bottom vent fully open
when lighting the stove.
Put rolled-up sheets of newspaper (5 - 10) or two solid alcohol tablets into the stove with
ca. 1 kg of well-dried kindling on top, then light the entire pile.
Once the wood is fully ignited, carefully place a small piece of fuel on top, without putting
out the fire. Once the fuel is glowing, add more. Proceed in this manner until the entire grate
is covered with glowing fuel. Now you can put in as much coke as will fit beneath the smoke
plate. When firing the stove, the door must be closed as quickly as possible after lighting the
fuel, as coke can only burn when all the air is coming through the grate and up through the
fuel, i.e. when all the air is coming through the grate and up through the fuel.
