operation and perfect combustion. All fireplace heaters produced by our company are tested in accordance with
3 240/2002 or 229/2002.
Please read through the manual and technical sheet thoroughly. The user is obliged to get properly acquainted
with proper installation and operation of this device with regards to its safe operation. Please keep the manual
and technical sheet so that you can brush up all the information necessary for the correct operation of your
fireplace insert before each heating season.
We only provide a warranty on our products if all the instructions listed in this operation manual are adhered to.
2. Technical description
Fireplace inserts are intended for building into stoves in various interiors (apartments, recreation buildings,
restaurants). Romotop spol. s.r.o. fireplace inserts are manufactured from quality construction materials cast
metal, CORTEN steel and quality construction and fittings steel, with stressed parts made of HARDOX steel.
The surface of steel constructions is protected by a refractory opaque paint. Refractory paints are not anti-
corrosive. The combustion chamber of full-plate fireplace inserts is padded by removable chamotte desks, which
are not connected by any paste material to prevent damage by heat dilatation. The combustion chamber can be
firmly closed by doors with special heat-resistant glass. The glass not only increases the aesthetics of the
flickering flames, but also facilitates pleasant heat radiation. The glass also prevents the sparks from the burning
wood and smoke from entering the room. The floor of the combustion chamber is usually equipped with a
removable cast-iron grate. Usually, a barrier, or alternatively a sheet metal or ceramic mould, is placed in front
of the grate to prevent the fuel falling and sliding onto the doors (front window). Grate fireplaces include room
for an ashpan under the grate. Some types allow custom-configuration of the flue pipe throat for top- or back-
side exhaustion. Some types of fireplace inserts have a rotary exhaust flue pipe throat. The fireplace insert
design may include a single coating or be supplemented with an external coat of zinc-coated sheet metal with
outlets for connection to the heat system. Installation of a support fan is recommended for vertical heat pipes
longer than 4m.
Fireplace inserts equipped with a separate intake of primary and secondary combustion air include the
appropriate control elements. The primary air is taken to the burning fuel (usually through the ashpan and grate)
and is used for primary combustion. The secondary air supports combustion of residual combustible gases in the
exhaust, increasing the output of the heater and significantly reduces the amount of pollutants escaping into the
atmosphere. The secondary air is mostly taken to the area above the burning fuel. Its presence causes the cold
air to roll around the inner side of the front glass. This process simultaneously prevents the blackening of the
front glass. The secondary air also participates in the primary combustion process when the primary air intake is
partially or completely sealed. Keep the primary air intake fully open at the beginning of the combustion
process, when the chimney draft is still weak. After the chimney heats up, you can partially or even completely
close the primary air intake, based on the target output of the fireplace insert. It is also possible to reduce the
fueling or limit the chimney draft by attaching a smoke shutter (a manual shutter in the flue pipe limiting the air
intake to at most 75%) to reduce the output of the fireplace insert. This is recommended especially for chimney
draft around and above 20Pa. The secondary damper is intended to fully close the stove when it is not in
operation. The fireplace and ashpan covers must always be closed except for starting operation, adding fuel and
removing solid combustion remnants to prevent exhausts entering the room.
It is possible to install heat and accumulation exchangers behind certain fireplace inserts, increasing the
efficiency of the whole stove and maximally utilizing fuel energy. Heat exchangers can be built into certain
types of fireplace inserts, in which case the production of warm service water also utilizes the double external
cover of the fireplace insert.
Some fireplace inserts are manufactured with a external air intake (EAI). This allows air to flow into the
combustion chamber in the fireplace insert from the exterior*, halls, technical rooms etc. Fireplace inserts with a
EAI are not dependant on the amount of air in the heated area. Thus, they not only contribute to a pleasant
atmosphere in your home, but also reduce energy expenses (since heated air already in the room is not

consumed). When installing the External air intake (EAI) outlet to the wall, it is important to make sure that the
pipe runs at a negative angle from the product. EAI lines must be isolated.
Fireplace inserts with a EAI are very convenient for stoves in low-energy houses. It is also possible to equip
the heating system of some fireplace inserts with EAI with electronic combustion regulation to increase
comfort. This can additionally increase the combustion process and stoking intervals, increase operation safety
and prevent uneconomic heating and over-heating of fireplace inserts (the shutter of the central air intake is
controlled by a control unit and servomotor in relation to the current combustion phase and output exhaust
temperature).
Warning: The fireplace inserts are not manufactured to provide continual heating and are intended for
periodic interrupted operation, mostly due to the need to empty the ashpan when the ash has cooled down.
*When connecting to an external air intake (from the outside), it is recommended to install double-acting flap
with a silicone cuff with possibility of closing air intake. This will prevent corrosion due to moisture
condensation when the product is not in use. The warranty does not cover damage caused by corrosion!
Attention, care must be taken to ensure that the damper is always open when the product is in operation!
3. Safety regulations
The fireplace inserts may be used in normal environments in accordance with -1 ed.2/2009. In
case of change of environment that could cause a temporary danger of fire or explosion (e.g. gluing linoleum,
PVC, working with paints, etc), the fireplace insert must be put out of operation in time, i.e. before the
occurrence of the dangerous situation. Furthermore, the fireplace inserts can be used only after the room is
thoroughly aired, preferably by wind draft.
A supply of sufficient amount of combustion air and room ventilation air must be ensured when the fireplace
stoves are in operation, especially with another heat device running simultaneously (approx. 8to 15 m3for
burning 1 kg of fuel)! When doors and windows are tightly sealed, this might not be the case! This is solved by
a CAI connected into a separate room. The regulation grate for combustion, ventilation and heating air must not
be obstructed. When stoking fuel, always open the door very slowly. You will prevent smoke and ash from
escaping into the room. The fireplace inserts require casual attendance and inspection.
Flammable fuels must not be used for stoking or heating! In addition, burning plastic material of any kind,
wood materials with various chemical bonding agents (chipboards, etc) or unsorted domestic waste with
remaining plastics is prohibited by law no. 201/20212.
Make sure to prevent children from handling the fireplace insert during heating. The fireplace insert
may only be operated by an adult person!
During heating all handles and knobs must be operated using a pair of tongs, hook or by a hand protected by
a glove (pot-holder) - there's a danger of burns! Objects made from flammable materials that could be set on fire
must not be stored on the fireplace inserts during operation and while hot. Please pay special attention when
handling the ashpan and when removing hot ash due to danger of burns! The hot ash must not get in contact
with flammable objects - e.g. when throwing in communal waste containers.
When the fireplace insert is used only seasonally and with unfavorable draft or weather conditions, special
attention must be paid when putting the stove into operation. When the fireplace stove is not in operation for a
longer period of time, the flue ways must be checked for obstructions before further operation.
The appropriate safety regulations for fireplace insert operation and installation must be adhered to in
accordance with
3.1 Safe distance:
3.1.1 Safe distance of fireplace inserts from flammable materials
When installing the fireplace insert in a place containing flammable materials belonging to class B, C and D,
the required safe distance in accordance with is 80cm from doors and 40cm in other
directions (see Figure 1), for fireplace inserts with double coating this amounts to 20cm. When installing the
insert in a place containing flammable materials belonging to class E or F, the distance must be doubled.
Information on the degree of flammability of certain building materials is listed in 501-1+A1/2010
and . When the prescribed safe distance of the heater from the flammable materials cannot be
kept, it is necessary to use a protective screen according to
Building materials sorted based on their reactivity with fire
A1 or A2
B akumin, Heraklith, Lignos, Ita
C
D
E or F
3.1.2 Safe distance of chimneys from flammable materials and building constructions
The safe distance from door case covers and similarly located building constructions from flammable
materials and from pipeline installation including its insulation is at least 20cm. The safe distance from other
flammable parts of the building construction at least 40cm (see fig.2) according to . This
includes building materials belonging to classes B, C and D as defined in -1+A1/2010 (see table
no.1) The same applies for walls and especially ceilings with plaster on a flammable surface, e.g. crates, planks,
etc.! When the prescribed safe distances cannot be kept, the danger of fire must be prevented through
construction solutions, non-flammable applications, heat-resistant insulations or protection screens.
3.2 Floor protection
Unless the fireplace is installed on a 100% non-flammable floor, it is necessary to place it on a non-flammable
insulation mat, e.g. metal plate (at least 2mm thick), ceramics, hardened glass, stone, in order to prevent the
flammable floor to exceed a temperature of during operation in accordance with 4.
According to 5.1.3.3 of the insulation mat must exceed the fireplace by at least
-80cm in the vertical direction from the insert stoking door.
-40cm in the horizontal direction from the insert stoking door.

Items made of flammable materials may not be placed on top of or at a less-than-safe distance from the
fireplace insert.
3.3 Chimney fire prevention measures:
Ordinary operation, especially with humid fuel, leads to the settling of ash and tar in the chimney. Neglecting
regular checking and cleaning of the chimney in accordance with the government regulation no. 34/2016
Coll. from 22st January 2016 increases the danger of fire.
In case of ash or tar catching fire in the chimney, please follow this procedure:
- do not under any circumstances extinguish the fire with water as it would create an abnormal amount of
steam and subsequently rip the chimney open
- if possible, the combustion chamber should be covered with dry sand, which will extinguish the fire
- close all intakes of air for combustion; if possible, cover the chimney. However, the smoke must not
accumulate back in the house
- contact your nearest fire fighting brigade to assess the situation and the necessity to report it as a fire
fighting emergency
- do not leave the house until the chimney is burned up; regularly check the chimney temperature and the
course of combustion
- contact a chimney service before starting a new fire in the stove to assess the state of the chimney and also
contact the manufacturer of the fireplace insert for inspection.

4.1 General
The fireplace insert must be installed on the appropriate stand supplied by the manufacturer or on a brick
pedestal on floors with an appropriate load capacity. In case of fireplace inserts with an enclosure, it is necessary
to also consider the weight of the enclosure! If the existing arrangement does not meet this basic requirement,
necessary steps must be taken (e.g. using a mat for distributing the load). Make sure that there is enough space
for cleaning the fireplace insert, connecting flue pipes and the chimney unless the chimney can be cleaned from
other place, e.g. a roof or through doors designed for this purpose.
4.2 Chimney connection
Before assembling the closed fireplace insert it is necessary to calculate that the chimney construction will be
suitable for the installed fireplace insert nominal output as far as design, vent size and effective height are
concerned.
A suitable chimney (minimum profile, chimney draft, tightness, etc.) is a basic condition for the proper
functioning of the fireplace inserts. You should therefore contact a chimney sweeper before installing the
fireplace insert. Chimney values are included in the attached technical sheet. A smoke shutter or a draft
regulator should be installed for chimneys with too strong a draft. Such a draft can cause problems during
operation, e.g. intensive burning, high fuel consumption and can also lead to permanent damage of the fireplace
insert.
The minimum effective height of the chimney for exhaust gas from the insert is 5m (measured from the hoop
to the chimney mouth). The chimney entry must be equipped with a chimney hoop. Consult the vent connection
with the vent manufacturer. The vents must lead at least 5cm below the lower ceiling. Connect the flue mouth
with the chimney in the shortest possible way so that the flue length is at most 1/4 of the effective height of the
chimney (i.e. 1.5m). Connect the flue tube and the knee together with an overlap in such a way that the
connections always agree with the exhaust gas flow, or abut using the connection rings. If the connecting piece
passes through construction elements with flammable materials, it is necessary to use protective measures in
accordance with . The norm states that the flue pipe needs to rise to the vents in the direction
of exhaust flow with a degree of at least . The tightness and firmness of the joints is crucial. The chimney and
stove connection must adhere to SN 73 4201/2016 ed.2. The casing of the chimney must not exceed a
temperature of during the highest operation temperature of the stove. The cross section of the flue pipe
vents must not be larger than the cross section of the chimney vent and it must not narrow down in the direction
of the chimney. If calculations show that the cross section of the flue pipe and chimney vent could be smaller
than the cross section of the exhaust throat of the fireplace insert, the cross section of the flue pipes will be
lowered immediately behind the exhaust throat of the fireplace insert, either gradually or at a discrete point. The
flexible flue pipe from the materials in accordance with table A.1. may only used in places where it may be
checked in accordance with 7.2.1 SN 73 4201/2016 ed.2, and unless the flue pipe leads through an open air its
checkability must be ensured in accordance with 7.2.5 . A vertical flue pipe may only be
used in the cases listed in 8.3.4 and 8.3.5 .
The fireplace insert may be connected to a shared vent with a gas appliance for multi-layer chimneys in
accordance with SN 73 4201/2016 ed.2.
Leakage of water into the product when using a vertical flue with a chimney function is not a reason
for a complaint!
4.3 Enclosure of fireplace inserts
Special expertise is required for building the fireplace insert into the fireplace. Fireplace construction is
adjusted by norm . Installation of fireplace inserts may only be done by reseller
authorized by Romotop spol. s r. o..
When installing and installing a fireplace insert, follow these guidelines:
1. All security and construction regulations listed above must be followed.
2. After installing the whole fireplace, the inlet and outlet of conventional air through any construction
parts must not be limited. The cross section of the inlet and outlet of convect air is listed in the technical
sheet.
3. To augment the final appearance of the fireplace, the dimensions of the door frames exactly match the
ceramic facing produced by Romotop spol. s.r.o.
4. The enclosure must be made of suitable, designated materials.
5. The warm conventional air outlet must be at least 30cm below the ceiling (figure 2).
6. An inflammable ceiling construction must be present above the conventional warm air outlet. Its
temperature must not exceed . Thus, the lower ceiling must be insulated from the effects of heat coming
from the fireplace by a barrier and at least one not fully closeable grated opening (figure 2) or a sufficient
layer of heat insulation.
7. The same requirements also hold for the walls next to the fireplace and for the floor. A ventilated air
space must remain between the heat insulation and the wall. It is recommended to glue aluminum sheets on
the surface of walls.
8. The wall of the fireplace must not contain electric wiring and water or gas distribution pipes. The wall
nor its surface may contain flammable materials or materials which may release harmful substances when
heated.
9. Minimal free distances must be kept between the fireplace insert and the cover (see technical sheet) for
the whole height and width of the fireplace insert, so that convect air can freely circulate and prevent the

overheating of the fireplace set.
10. Eventual air conditioning piping must be located at least 40 cm from flammable building constructions,
or it must be documented that the heat from the piping cannot cause the construction to catch on fire. Convect
air can reach temperatures of up to near the insert!
11. Do not forget that fireplace inserts also spread heat in the direction of the floor. The floor under the
fireplace and at a distance of at least 80cm in front of the furnace and 40cm to the sides of the furnace must
be made of an inflammable material. The distance is measured from the closer edge of the furnace. The
surface for the fireplace must have an appropriate load capacity.
12. Do not forget that when considering the use of wooden decorative ledges, these must be made of quality
wood with a humidity of at most 15% and that convect cooling air must flow around it with a gap of at least
1cm or they must be heat-insulated from the fireplace, so that their surface temperature does not exceed
13. When distributing hot air via natural air circulation, it is recommended to use horizontal pipes at most
4m long. When distributing hot air via forced air circulation, the length of pipes is not limited.
14. The pipes for distributing hot air must be tight and made of a material resistant to operating
temperatures. We recommend insulating them at the whole length, especially where they traverse walls,
ceilings or around flammable materials.
15. Hot air outlets must not be located at areas with materials susceptible to structural changes caused by
temperature fluctuations (e.g. polyester lining, certain types of wallpapers etc.)
16. No construction changes or adjustments may be performed on the fireplace insert!!!
All local regulations, including regulations concerning national and European standards. Have a specialized
project elaborated before construction.
The project documentation must be elaborated in a scale of 1:10 or 1:20. Before the fireplace enters
operation, it must be inspected by a chimney sweeper and the exhaust path must be inspected in accordance with
Chapter 9 of . Inspection of the flue pipe connection to the insert and chimney vents
should be performed before closing the exhaust path to the hot air chamber. The result of the inspection shall be
recorded in the exhaust gas inspection report including the technical report according to Decree No. 34/2016
Coll. Please keep the Revision Report and the Technical Report carefully!

5. Operation manual
5.1 Fuel
It is only allowed to burn wood in fireplace inserts in accordance with law No. 201/2012 Coll.. To reach the
nominal parameters of the heater, we recommend using dry logs with a diameter of 5-8 cm and length of 20-30
cm and with a humidity below 20% (ideally 10%). Oven wood and chopped pieces of wood should be used
only when starting the fire. Recommended humidity can be obtained by storing the chopped logs for at least two
years in a ventilated shelter.
The fireplace insert should be heated to a nominal output stated in the technical sheet, i.e. the burning of a
given amount of allowed fuel per 1 hour. Long-term excessive output could damage the fireplace stove.
