8. Advice on Lighting a Fire

The best way to light a fire is with the use of fire
lighters briquettes and split small wood logs that are
dry. Newspapers cause a lot of ashes and the ink
is damaging for the environment. Advertising flyers,
magazines, milk cartons and similar are not suitable
for lighting a fire. Good air supply is important at
ignition. When the flue is hot the draught increases
and door can be closed.
Warning: NEVER use a lighting fuel such as
petrol, paraffin, methylated spirits or similar
for lighting a fire. This could cause injury to
you as well as damaging the product.
Use clean and dry wood. The wood logs should dry
for a minimum of 6 months after being chopped.
Humid wood requires a lot of air for the combustion,
as extra energy/heat is required for drying the humid
wood. The heat effect is therefore minimal. In addition
this creates soot in the chimney with the risk of
creosote and chimney fire. The wood should have no
more than 20% moisture content.
Warning: NEVER use impregnated wood,
painted wood, plywood, chipboard, rubbish,
milk cartons, printed material or similar. If any
of these items are used as fuel the warranty is
invalid, as they can release dioxin gasses that
may damage the insert when burnt.
These gasses are also very harmful to you
and the environment.
In order to obtain an optimal combustion, the
temperature needs to reach 600-800ºC. It is
recommended to keep an even fire with a small
amount of wood. If too many logs are put on the
hot ember, the air supply will not be sufficient for
reaching the require temperature, and the gases will
be released unburnt. For this reason it is important
to increase the air supply just after adding the logs
in order to have proper flames in the burn chamber
so that the gases are burnt. Open the ignition vent
control or leave the door slightly open until the flames
have a good grip.
Note that too much air supply to the combustion
may create an uncontrollable flame that very quickly
will heat up the entire insert to extremely high
temperatures (valid when heating with closed or
almost closed door). For this reason you should never
completely fill up the burn chamber with wood.
Use split wood logs rather than whole round pieces
of wood. This will give a better heat efficiency and

cleaner combustion. It is also an advantage to let
the wood reach room temperature before being
used as it will burn better. The inserts from Nordpeis
are intended for, and only approved for, clean wood
combustion.
