Operation

Starting the fire for the first time
It is the responsibility of the installer to start the fire for the first time and to
measure the draught. Remove the adhesive labels, any cardboard packing
and check that there is nothing in the ash pan.
Start with a gentle fire, then gradually increase the load. This progressive
bringing up of the temperature allows the materials to dilate slowly and
stabilise. Although this may not be visible, the fireplace may still contain a
considerable amount of water. Wait at least two weeks before using your
closed fire normally. Smoke and a smell will be given off at first, due to the
presentation paint, but this will fade in time. Proceed in this way for several
days before using the fire normally. This initial bringing up to temperature
should be done with the windows of the room open. During the first heating,
check the draught against Table 1. Adjust the draught regulator if required.
- Operation as a closed fire.
• Lighting the fire
Spread some crumpled paper on the bottom of the fire, place some small
wood on top and some small split logs. Position the controls as shown in
Table 3 (lighting the fire). Light the fuel you have prepared, close the loading
door and wait for embers to form. When the fire has started to burn well,
load the fire and place the controls on the "normal burning speed" position
(Table 3).
Never use petrol, alcohol or heating oil ...
• Reloading
Whenever possible, only reload the fire when only a bed of embers remains
and the flames have died down. Open the door slightly then wait a moment
before opening it completely so as to avoid smoke billowing into the room
and embers falling out. Reload and close the door. It may be necessary to
increase the air intake for a few moments to encourage the fire to get going.
It is preferable to load in several goes rather than putting too much wood
in at the start.
• Wood load
To reach the rated burning speed, the load required is 3 logs representing
12 to 13 kg of firewood

Operation at reduced speed
• Spread the embers into an even layer.
• Load 2 or 3 logs.
• Let the fire start, then gradually position the air control in accordance
with Table 2 (reduced speed).
After using the fire at reduced speed, make a strong fire to heat up the
chimney duct and remove any condensation that may have been caused
by the reduced combustion.
Avoid using the fire at reduced speed for prolonged periods. The tempe-
rature of the smoke is insufficient and it cannot be evacuated before it
condenses in the chimney duct.
- Operation as an open fire (162C / 168C / 163)
Using the fire with the window lifted up means you can enjoy the fire directly.
The output of the appliance, however, compared to its use as a closed fire,
will be considerably reduced.
At night, or even in the event of a short absence, the window should
be closed. In this case, place the controls as for the closed fire.
• Lighting the fire
Proceed as for a closed fire.
Normal burning speed
The speed of combustion can only be adjusted by the quantity of fuel. In
this configuration, use only wood. Ensure that the air can circulate between
the logs (at least 2 logs at any one time). The correct functioning of the
appliance depends on a sufficient intake of fresh air. The load of wood must
be placed towards the back of the firebox, in order to avoid embers falling
out of the fire.
