Fire Duct; De-Ashing - deville C07751 Notice D'utilisation

4.4.2.2 Fire duct

- The burning required is obtained by using the control devices (see § 4.3) and selecting a load
matching your needs, i.e.:
. For maximum heating, load the appliance with 3 logs of approx. 10 cm diameter (air damper open)
(Fig. 3).
Use this position only temporarily, to heat the rooms following prolonged absence.
. For intermediate heating, use a smaller load : one or two logs (air damper half-open) (Fig. 3).
. For a long-lasting heat output with a slow combustion rate, use 1 or 2 non-split logs with a diameter
superior to 15 cm (air damper closed) (Fig. 3).
- To get a long-lasting combustion rate, reload on a merely burning bed of embers.
- For rapid restarting of the fire, add some kindling wood, load the logs, and only if necessary keep
the door partly open for several minutes, without leaving the appliance unattended. Thereafter, use
the controls as per the instructions (paragraph 4.3). This method gets the fire going quickly again,
especially if the wood is slightly damp.
- Change the burning rate (switching from a slow combustion rate to a normal rate for example)
before reloading, during the combustion stage of the embers, to enable the appliance and smoke
duct to change progressively from one burning rate to another.
- To prevent smoke from driving back and the ash from entering the room, at the time of loading,
opening the door requires a number of precautions:
. Open the door partly, waits for the open door suction to start, and open the door slowly.
- Using the stove in continuous mode and a slow combustion rate, especially in milder temperature
conditions (bad draught) and with wet timber, leads to an incomplete combustion and the formation
of tar and soot deposits :

- After the stove has been used in slow combustion mode, the front glass may darken because of a
slight soot deposit, this deposit will burn off (by pyrolysis) with the next hot fire (higher combustion
rate).
The fitting of a suction moderating flap in the connecting duct enables to control the burning, notably slow

4.4.2.3 De-ashing

The air used for burning the wood comes in under the grate when the damper is open. This air also
ensures the cooling of the grating. Therefore, it is vital, to ensure optimum performance and prevent
the degradation of the grating due to overheating, to prevent any obstruction by performing regularly
de-ashing operations and evacuating the ash :
- Use the scraper (1) to de-ash the grating (Fig. 4).
- The ash pan, located under the grille, can be easily removed using the poker (Fig. 5).
- The level of ash must never reach the stove's cast iron grating : de-ash every 2 to 3 days.
- Remove periodically any ash which spilled accidentally in the ash box compartment.
Alternate the slow burning periods with returns to normal burning.
Burning small loads is recommended
burning, enabling long lasting heating (see installation manual).
