Trouble Shooting
The most common assumption amongst stove users is a fault with the stove. This is incredibly
unlikely due to the limited mechanical nature of a wood burner. Stoves are not designed to be air
tight and the effective lighting of a fire, control and draw is dictated by the chimney system which
can easily over or under draw due to many factors.
Fire Won’t Light
Is there sufficient ventilation in the room to supply air to the stove? A permanently open-air brick
must be installed with your Woolly Mammoth stove and extractor fans must not be present. Are
the air intakes open and free from blockages? Is an approved fuel being used in line with the
guide in this user manual? Has the chimney been swept? Does the flue draw fall between the
required levels?
Fuel Burns Quickly
Over firing occurs when too much air is being drawn into the stove due to the chimney system
over drawing. Do the doors close correctly? Are rope seals intact? Are the glass retaining clips
loose? Is the correct fuel being used? It is not unusual to require a draught stabilizer to reduce the
draw on a stove due to excessive flue draught.
Blow Back
If the doors are closed prematurely or intakes are not open enough after refuelling, small
explosions can force air through the seals of the stove.
Smoke Leaks From The Stove
If the chimney system has been installed in line with current building regulations by a registered
installer, this will always provide the required draw to remove all harmful gases and smoke from
the fire box. If smoke is emitted from the stove, please refer to your chimney installer. Is the
system at least 4.5m? Make sure there are no horizontal runs greater than 150mm. Is the chimney
blocked? Are there strong winds pushing the smoke back down the chimney? Is the flue diameter
correctly sized? Are air vents open?
Glass Blackens Quickly
The air wash system fitted as standard in a Woolly Mammoth stove utilises the most effective
system of warming the air along the entire length of the fire box before jetting it down behind the
glass. Increasing the heat and opening the secondary air intake will clear the glass.
