The best time to remove ash is in the morning, after an overnight fire when the fireplace is
relatively cold, but there is still a little chimney draft to draw the ash dust into the fireplace and
prevent going out into the room.
Ashes should be placed in a tightly covered metal container. The container must
be placed on a non-combustible floor or on the ground well away from all
combustible materials. Ashes almost always contain live embers that can stay
hot for days and which release carbon monoxide gas. If the ashes are disposed
of by burial in soil or otherwise locally dispersed, they should be kept in a closed
metal container until they are completely cooled. No other waste should be
placed in this container.
NEVER STORE ASHES INDOORS OR IN A NON-METALLIC CONTAINER
OR ON A WOODEN DECK.

Air Intake Control
Once the firewood, firebox and chimney are hot, air intake can be reduced to achieve a steady
burn.
As the air intake is reduced, the burn rate
decreases. This has the effect of distributing
the thermal energy of the fuel over a longer
period of time. In addition, the flow rate of
exhaust through the appliance and flue pipe
slows down, which increases the duration of
the energy transfer of the exhaust gases. As
the air intake is reduced, the flame slows down.
If
the
flames
diminish
disappearing, the air intake has been reduced
too early in the combustion cycle or the wood
used is too wet. If the wood is dry and the air
control is used properly, the flames should
decrease, but remain bright and stable.
On the other hand, too much air can make the fire uncontrollable, creating very high temperatures
in the unit as well as in the chimney and seriously damaging them. A reddish glow on the unit
and on the chimney components indicates overheating. Excessive temperatures can cause a
chimney fire.

Fire Types
Using the air intake control is not the only way to match the fireplace heat output to the desired
temperature in the house. A house will need far less heating in October than in January to
maintain a comfortable temperature. Filling the firebox full in fall weather will overheat the space.
Otherwise, the combustion rate will have to be reduced to a minimum and the fire will be smoky
and inefficient.
