2. Build a bed of fuel consisting of crumpled newspaper and a pyramid of kindling
3. Light the newspaper and add larger logs as the kindling starts to burn
4. You may need to leave the stove door open a jar to provide sufficient air at first
5. Once the fire is established, control the burn using the appropriate air intake. Wood
requires an air supply from above for secondary combustion and is controlled by the
secondary air intake whereas coal requires this from below using the primary air intake
6. Allow for a small build-up of ash when burning wood to insulate the fire box sufficiently
or to remove any unwanted ash build up, simply operate the externally controlled
riddling grate.
7. To extinguish the fire, close the primary air intake fully and then the secondary. Do not
completely close all air intakes at once to allow the fuel to efficiently burn out. Once
extinguished, close all air intakes and dampers completely
8. It is advised to light a number of small fires to ‘bed in’ your new stove and ensure the
longevity of the metal construction and any coatings. You must avoid over firing.
Note that the Woolly Mammoth 5WS (WideScreen), WM5 & WM7 have modified secondary air
controls to prevent the complete closure of the air supply. This is implemented to minimise the
potential for smoke emissions .
Spring and Autumn syndrome
Stoves utilise the effect of air current within the flue to both exhaust the products of combustion
and to induce air into the stove. Normally, because the air within the house is warmer than the
outside air the flue is exhausting air from the stove even when it is not operating.
• A hot flue does not “draw” air into a stove, it is the
differences of densities that motivate the lighter gases
upwards.
• The greater the temperature difference between the gases
within the flue and the surrounding air, the greater the
difference in densities and the greater the motivation.
• The taller the flue, the greater the weight of the
equivalent volume of denser air, the greater the motivation.
During the changeable weather conditions of Spring and Autumn the outside temperature can rise
suddenly and become warmer than the temperature within the house.
