FIRST START-UP AND OPERATION
Prior firing up you should set a slider of air inflow adjustment to
the maximum opening (marking on the handle, presented on figure 31).
Then, open the doors of the insert and place fire starter and fragmented
wood, then charge approx. 1 kg of dry hardwood, fire up and close the
doors.
It is forbidden to use other materials than described
in this manual for firing up, in particular flammable
chemicals such as: oil, petrol, solvents and others.
After firing up refill combustion chamber with wood, placing fuel in
a way that reasonably fills the combustion chamber. Recommended
single fuel charge is given in table 2. Method of fuel laying is shown on
figure 32

Method of fuel arrangement during firing up
The intensity of the fuel combustion process should be adjusted by
proper setting of the air supply adjustment slider. Doors of fireplace
insert should be closed during operation of the fireplace insert.
The odour of paint from the body will be released during the first
several hours of combustion. This is completely normal. You should
strongly vent the room at that time. Check tightness of joints once again
when fuel is completely burned out and equipment has been cooled
down.
Housing components will be very hot during operation.
You must exercise caution.
You should control the level of filling of the container with ash.
Overfilling of container results in lack of cooling of the grate and limits
air supply for combustion. To empty the container you should damp a
fireplace, close inflow of air for combustion and wait until surface and
parts of the fireplace insert cool down. Then open doors of the insert,
remove the grate and take out the container. Remove ash from con-
tainer and re-install in the body of the insert. It is recommended to
empty ash container prior to each successive start-up of the equipment.
Do not fill the furnace completely with wood. The charge should
not exceed 1/3 of the volume of the combustion chamber. You should
use only hardwood (recommended beech, oak, hornbeam) of low mois-
ture content (below 20%).
During combustion the doors should be opened only when the fuel
is being added. Prior to adding the wood you should wait until flames
fall down and charge is completely burnt out leaving an igniting layer of
glow. After firing up refill combustion chamber with wood, placing fuel
in a way that reasonably fills the combustion chamber for the combus-
tion period expected by the user based on personal experience. The
intensity of the fuel combustion process should be adjusted by proper
setting of the air supply adjustment slider.
During operation doors in DEFRO HOME INTRA fireplace inserts
in G version can be only opened by lifting. Hinged door opening for this
versions is intended only for service purposes and it should not be
opened during combustion.
Never stand in front of the fireplace insert door while
opening. Burn risk.
Hinged doors should not be opened during combustion
in case of G version of the DEFRO HOME INTRA fire-
place insert. Lifting upwards is a normal method for the
opening of guillotine doors.
Only one door of fireplace in case of T version may be
opened during combustion!
6.3.
DAMPING
Damping is executed by the closing inflow of INTRAry air. In such
case you should wait until the fuel completely burns out in a natural
way.
If it is necessary to quickly damp a flame you should charge fur-
nace chamber with dry sand or ash. It is not allowed to damp a flame
by pouring it with water because it may damage components of the
equipment.
After a longer break in equipment’s operation you
should check flow capacity of the flue.

CLEANING AND MAINTENANCE
All operations related to cleaning of all components
should be carried out when the fireplace is completely
cold. It is required to use protective gloves.
It is a good practice to ensure good ventilation of the
room during cleaning of the fireplace.

BASIC OPERATIONS AND CLEANING BY THE USER.
Any service and maintenance works are to be carried out with
meticulous care and only by adults familiarized with this manual. The
fireplace insert should not be cleaned in the presence of children.
Any service and maintenance works are to be carried
out with meticulous care and only by adults familiarized
with this manual. The dry fireplace insert should not be
cleaned in the presence of children.
Protective gloves, glasses and headgear are to be worn
to operate the equipment.

CLEANING BEFORE EACH STARTING
Prior to every successive start-up of the equipment the ash con-
tainer should be cleaned and emptied, handling the ash with due care.
