Prolonged burning
You will obtain a long burning time by burning a few (at least 2) very large logs and regulating as
required with the regulator knob. You obtain the slowest combustion by turning the regulator knob
counter-clockwise to the minimum setting. At this setting, the primary air is completely shut off, which
means that you need to manually supply combustion air after firing. You do this by first turning the
regulator knob to the maximum setting, and then after 5 minutes slowly turning it back towards the
minimum setting while making sure not to choke the flames. During slow combustion you may find
it difficult to keep the glass pane clean. The included cover plate also helps increase the burning time,
drawing C1. It is recommended that the cover plate is always applied. Place the cover plate (1) on top
of the shaking grate. The cover plate is raised approx. 8 mm over the grate to ensure that the primary
combustion air is evenly distributed over the bottom of the combustion chamber.
Insufficient firing
If the fireproof materials in the combustion chamber are “black” after firing, the stove is polluting,
and the automatic system is not working properly. You therefore need to open the air intake with the
regulator knob. Burning a larger amount of wood may also be required.
Types of fuel
We recommend using birch or beechwood, which has been split and stored for at least one year
outdoors under cover. Wood stored indoors tends to become too dry and burn too quickly.
Briquettes give off a lot of heat. Certain types expand considerably, thus causing an uncontrollable
combustion.
How to achieve the best combustion
• Use clean and dry wood.
Wet wood results in inefficient combustion, plenty of smoke, and soot. Furthermore, the heat will
dry the wood, not heat up the room.
• The fire should only be stoked with a little wood at a time.
You achieve the best combustion by starting up a fire often and using only a little wood. If you use
too much firewood, it will take some time before the temperature reaches a level where you achieve
a good combustion.
• Make sure there is the right amount of air.
You should also make sure that there is plenty of air – especially in the beginning - so the temperature
in the wood burning stove climbs quickly. In this way the gasses and particles released during the
combustion will be consumed by the fire. Otherwise they build up soot in the chimney (constituting
a chimney fire risk) or will be released in a non-combusted state into the environment. The wrong
amount of air supply creates inefficient combustion and a modest effect.
• Don’t savour the fire during night time
We advise against adding fire wood to your stove and reducing the air supply at night in an attempt
to still have some embers left in the morning. If you do so, large amounts of hazardous smoke will
be emitted, and your chimney will be exposed to unnecessarily large amounts of soot with the risk
of a chimney fire.
HWAM 3310 and HWAM 3320 are EN 13240 approved only for firing with wood. Do not
use chipboard, lacquered, painted or impregnated wood, plastic, and rubber.
