The fireplace insert is a heating and decorative device, allowing construction of a complete heating
system based on distribution of hot air. It is not an autonomous heating device but a component of the
heating system. Due to the above reasons, its operation and safety largely depends on the method of
installation and materials used. Considering that, it is recommended that installation of the insert is
commissioned to an Authorised KFD Fitter, guaranteeing an appropriate standard of service.
Installation of the fireplace must be performed in compliance with applicable regulations (table 5).
All domestic and local regulations ought to be observed.

1 Construction of the fireplace
1.1 Placement of the fireplace
The installation of fireplace insert starts with preparing a correct place for the fireplace
construction . It ought to be characterised with:
-strength of the base (floor) appropriate to the type of insert and weight of enclosure
(on average, from 450 to 850 kg); the floor must be reinforced and/or the weight ought
to be distributed over a larger area, if this condition is not fulfilled,
-the chimney with parameters (diameter and height) suitable for the type and power of
the insert (chapter 3) and it must be resistant to humidity produced during the
combustion process, and temperatures occurring during combustion of solid fuels,
-adjustable supply of fresh air from outside the building (min. 200 cm²), conducted to
the room in which the fireplace insert is installed,
-the place of installation should not contain any combustible materials or non-heat
resistant materials, electrical or hydraulic installations,
-the fireplace must not be installed in a room with mechanical exhausts (ventilation) „If
the fireplace can be installed in a room with mechanical ventilation, please observe
local regulations.
-floor under the fireplace and 60 cm in front of the fireplace must be made from
incombustible materials (e.g. terracotta or natural stone).
Once the place of installation is prepared as above, construction of the fireplace pedestal
constituting the fireplace foundation may proceed. The pedestal structure must guarantee
unobstructed flow of air from underneath, along external walls of the insert and upwards,
ensuring the minimum air flow section required for the given type of insert (table 4). If the
insert does not have its own supporting structure, the pedestal constructed as above may
become its foundation. While placing the insert, make sure that the insert base does not limit
the required air flow area (figure 1).

1.2 Chimney
Once the insert is placed correctly, the outlet stub pipe of the insert ought to be connected to
the chimney by means a respective duct with the required certification, allowing application in
solid fuel furnaces. The angle of connection to the chimney ought to be app. 45° (figure 3 –
do not use a 90° elbow), and the connecting duct ought to have a diameter corresponding to
diameter of the stub pipe of the combustion gas outlet. If the diameter needs to be reduced,
use appropriate reducer couplings selected in compliance with the diagram (figure 21).
Use of a flexible connecting pipe eliminates the “insert movement” phenomenon due to
tensions caused by thermal expansion if immovable connection elements are used.
Moreover, if immovable connections are installed, thermal compensation of the expanding
pipe needs to be insured and ducts must have inspection holes allowing access through
openings in the fireplace enclosure (e.g. grids in the hood).
KFD ECO inserts require installation of an additional reduction on the stub pipe of the
fireplace insert, depending on the kind of connecting pipe used for connecting the fireplace
insert. The reducing element is to be fitted with the smaller dimension inside the stub pipe of
the fireplace insert. Next, the flexible connecting pipe is to be placed inside the upper part of
the reducing element. The reducing element must not be based on the axle of the chimney

damper, as this may cause problems in using the chimney damper or a damage. It is
recommended that fragment of the reducing element placed inside the fireplace insert stub
pipe should have the maximum height of 50 mm. Connection of the reducing element with
the insert and with the connecting pipe must be sealed. The process ends with connection of
the connecting pipe with the chimney. In case of flexible connecting ducts, a transition
element appropriate to dimensions and kind of the chimney must be purchased. Please
remember during connection that the connecting pipe must be mounted on the external side
of the transition element.
Materials which can be used for installation are specified in chapter 4.
After removing all labels from the surface of the glass pane and thorough cleaning of glue
residues, perform test lighting up of the initially connected insert. Fire ought to be increased
gradually to avoid occurrence of excessive internal tensions in the insert body.
During test lighting up of the insert, check tightness of connections with the chimney,
tightness of door gaskets and operation of adjusting elements (combustion rate adjustment
levers). During the first lighting up and annealing of the insert, heat resistant paint covering
the insert surface smells while hardening, which is a normal phenomenon you should not be
concerned with.
Please observer appropriate EN norms and local regulation which concern the chimney.
Figure 4 presents regulatory requirements related to height of the chimney with respect to the
roof ridge.
Basic requirements for chimneys to be used for connection of fireplace inserts stipulate that
the chimney:
-should have a circular section or another appropriate section as required by applicable
regulations,
-should be thermally insulated and waterproof, made from materials resistant to very
high temperatures, products of combustion and possible condensate,
-should not have any narrowings or vertical deflections over 30º,
-in case of a rectangular section, the maximum proportion of the sides may not exceed
½,
-minimum chimney height is recommended as 4m measured from the connection of the
connecting pipe to the chimney,
-must have a cleaning hole for collecting and emptying of combustion process
residues,
-an excessive section of the chimney may cause problems in using the fireplace; to
avoid that, “cladding” of the chimney may be made throughout its length,
-an insufficient section of the chimney may cause significant draught reduction and, in
consequence, smoking of the fireplace insert.
Negative pressure in the chimney ought to be 12 Pa (1.2 mm column of water). Negative
pressure measurement ought to be performed during operation of the fireplace (at nominal
combustion rate). If the negative pressure exceeds 17 Pa (1.7 mm column of water), a
draught terminator may need to be installed. Similarly, in case of insufficient negative
pressure, a draught enhancing attachment ought to be fitted.

1.3 Tip of the chimney
The strength and stability of draught in the chimney depend as well on the kind of chimney
tip. It ought to reach above the roof ridge and protect the outlet against rain and adverse
impact of wind (figure 7).

Figure. 7 Example chimney tips: a) prefabricated tip, b) brick version, c) steel tip –so called
chimney cowl.
The chimney tip ought to meet the following requirements:
•its internal diameter should be equal to the diameter of the chimney,
•usable diameter of the combustion gas outlet is to be twice the size of the chimney
diameter,
•it ought to protect the chimney against adverse weather (rain, snow) and foreign bodies,
•it ought to be easily accessible for maintenance and cleaning of the chimney,
•in case of two adjacent chimneys, tip of one chimney ought to be located at least 50 cm
above the other one, in order to avoid mutual interference of produced negative
pressure (figure 8),
•chimney tip ought to be situated 6 m away from any obstructions, such as walls, rocks
or trees according to the local in regulations. Otherwise, the chimney ought to be
extended to protrude approximately 1 m above the existing obstruction. The chimney tip
ought to be situated approximately 1 m above the roof surface (figure 9).

1.4 Ventilation conditions for KFD ECO fireplace insert installation
Rooms in which KFD ECO fireplace inserts are installed ought to meet the technical
conditions specified in the local regulations. (Polish: REGULATION OF THE MINISTER OF
INFRASTRUCTURE dated 12 April 2002 on technical conditions to be met by buildings and
their situation –Polish Journal of Laws of 15 June 2002, № 75, item 690 – in particular, in
paragraph 150 of the above mentioned act –regarding ventilation and air conditioning).
1.5 Supply of outdoor air
Additional outdoor air needs to be supplied to fireplace inserts. Pursuant to data specified in
table 4, section area of the air inlet ought to be 200 cm2. The following conditions must be
observed while constructing the installation:
-air is to be supplied from the direction of prevailing winds,
-air is not to be supplied from the direction of the street,
-a damper is to be installed to allow cutting off air supply while the fireplace is not in
use,
-air from other rooms of the house or flat must never be supplied,
-outdoor air may be supplied by installing window- or wall-mounted intake ventilators
with mechanical adjustment.
