bottom of the combustion chamber (5) , side walls and the back wall (6) are lined with
warmth accumulating ceramic lining. It has a double floor (7) which is also the primary
and secondary air inlet, as well as the place for the ash pan (8) and grate (9) . The air
intake is applied through a spigot (10) of diameter 125mm, which contains the air flow
control mechanism - throttle (11) . Thanks to this solution, the inserts requires only one
air supplying pipe from the outside. The throttle is regulated with a lever (12) installed
under the front panel.
Operation

It is regulated by turning the lever to the front or back. In the maximum retracted
position of the lever, the air supply is shut off, while in the extended position, the
maximum air inflow is opened. The air goes through the throttle to the ash pan (8) , and
then to the grate (9) . It escapes to the combustion chamber through the slots in the
grate reach. Secondary air enters the combustion chamber through the combustion
gases after burning system (13) , which are holes made in the ceramic concrete. Above
the combustion chamber, there is a special plate made of ceramic concrete called a
deflector (14) , over it, there is a second deflector made of heat resistant sheet metal
(15) . The double deflector system is a conventional channel enhancing heat exchange.
During burning, the combustion gases flow over the walls of the combustion chamber,
the ceramic deflector and then the steel deflector. Then they get out to the flue (16)
and through the wires they reach the chimney. The air surrounding the encased insert is
heated (by convection) and escapes into the room through appropriate ventilation slots
in the encasing of the fireplace. This ensures heat recovery and provides an additional
source of indoor heating.
Installation of the air intake pipe:
An air intake pipe for self-assembly is separately attached to each fireplace. To mount
the pipe, place the feet adjusting the fireplace insert on a sufficiently high ground so that
it is possible to install the air intake pipe in the mounting hole, place the air intake pipe
in the mounting hole and turn the pipe to tighten it.

Door opening and closing
ATTENTION!
Do not slam the door when closing - this may cause the glass crack or break.
2.4. ARDENTE SERIES
Structure
Fig. 15. ARDENTE insert - with standard doors (on the right) and guillotine door (on
the left) - page 166.
Tab. 11-14. Technical data of fireplace inserts – page 138-141.
The fireplace insert consists of a body (1) and a front (4) . The body (coat of the insert) is
made of 4 mm P265GH boiler steel. The front of the insert consists of steel door made of
a special profile and profiled steel metal sheet, heat-resistant glass and a handle (3) . The
door is screwed to the bars (2) , which are fastened to the body of the insert. The front
comes in two options. The first one is a swing door that opens to the right or left and
the other one, is a guillotine - the door is raised up. The configuration of the coats also
occurs in two configurations. Double-sided, where the steel door is located on the front
