SLOWLY. 
4.4.2 Ash Removal 
Ash should be removed from the firebox every two or three days of full time heating. Do 
not let the ash build up in the firebox because it will interfere with proper fire management. 
The best time to remove ash is after an overnight fire when the stove is relatively cool, but 
there is still some chimney draft to draw the ash dust into the stove and prevent it from 
coming into the room. 
After ashes have been removed from the stove and placed in a tightly covered metal 
container, they should be taken outside immediately. The closed container of ashes should 
be placed on a non-combustible floor or on the ground well away from all combustible 
materials pending final disposal. Ashes normally contain some live charcoal that can stay 
hot for several days. If the ashes are disposed of by burial in soil or otherwise locally 
dispersed, they should be retained in the closed container until all cinders have thoroughly 
cooled. Other waste shall not be placed in this container. 
NEVER STORE ASHES INDOORS OR IN A NON-METALIC CONTAINER OR ON A 
WOODEN DECK. 
4.4.3 Raking Charcoal 
Rekindle the fire when you notice that the room temperature has fallen. You will find most 
of the remaining charcoal at the back of the firebox, furthest from the door. Rake these 
coals towards the door before loading. There are two reasons for this raking of the coals. 
First, it concentrates them near where most of the combustion air enters the firebox and 
where they can ignite the new load quickly, and second, the charcoal will not be smothered 
by the new load of wood. If you were to simply spread the charcoal out, the new load will 
smoulder for a long time before igniting. 
Remove ash first, and then rake charcoal towards the front of the firebox before loading so 
that it will ignite the new load.
