2. INTENDED USE OF THE INSERT
TRINITY fireplace inserts are intended for use as an additional source of indoor heat. They are equipped with slow-
burning hearth and manual loading of fuel and are closed with a guillotine-type door (a pull-down door)
The inserts have been designed to be fuelled, most of all, with the wood of deciduous hardwood. We especially
recommend seasoned birch wood. During the burning process, thermal energy is released and transferred from
the combustion chamber by conduction and radiation.
In conformity with PN-EN 13229:2002 standard, the hearth of the insert is classified as 1b, with manual loading of
fuel and closed doors and it can be encased or built into a recess in the wall.

4. STRUCTURE AND OPERATION OF THE INSERT
Figure 3. General construction of TRINITY insert
The fireplace insert consists of a body 1 and a front 4. The body of the insert is made of 3 mm P265GH boiler steel.
It is enclosed with the cover 2and lower and upper bar 3. 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 5. The door is screwed to the bars
15, which are fastened to the body of the insert.
The front is available in the guillotine option - the door is raised upwards with the possibility of opening the side
door by wing (the opening of the side door is used only to service the insert).
The combustion chamber 12 is lined with the ceramic concrete 14 on the bottom and back wall. It is made of a
double-walled floor which is the intake of primary and secondary air, as well as the location of the ash pan 10 and
grate 11. The air inlet 9is realized through a spigot of 150 mm diameter and an expansion box 8 distributing air to
the individual primary, secondary and support air intake pipes 7. Thanks to this solution, the insert needs only one
pipe supplying air from the outside.
In addition, the insert is equipped with a bottom cover 6for mounting the air inlet from below.
The throttles are regulated by levers located under the front (primary 23 and secondary air 23) and under the side
door 19 (primary air supporting and cleaning the glass). To regulate them, turning the lever to the right or left. In

WWW.HITZE.PL
FIREPLACES | STOVES | BIO and GARDEN HEATERS | ACCESORRIES
Page 8
the maximum right lever position, the air supply is cut off and in the left position, the maximum air supply is
opened.
The primary air, passing the throttle, goes to the ash pan 10 and then to the grate 11. And through slots in the
grate, it reaches the combustion chamber.
The secondary air enters the combustion chamber through the afterburner 13, that is, openings located in the
ceramic concrete panels. The insert is also equipped with an air curtain and additional throttle for faster burning
and to keep the glass pane clean.
Above the combustion chamber, there are special ceramic concrete panels called 16 deflectors (each TRINITY
series insert in has 2 deflectors).
Radiators (pipes) 17 are welded to the body of the insert. The radiators and deflector create a convective channel
enhancing heat exchange. During combustion, the combustion gases float around the walls of the combustion
chamber, the deflector, and horizontal radiators. Then they get out to the flue 18 and through the wires go to the
chimney.
The insert is equipped also with the tension 21 of the upper strip which assists in relieving the front of the insert,
bracket 22 for mounting the insert to the wall and in the case of a heavier installation, a fixing hole in the upper
strip 20 allowing to attach the insert to the ceiling. Both of these solutions prevent deformation of the insert during
assembly of heavier buildings and its future work.
The air surrounding the built-in insert is heated (convection) and escapes into the room through the appropriate
ventilation slots in the fireplace encasing - heat recovery and additional room heating.
5. DOOR OPENING AND CLOSING
5.1. Guillotine type with hooks (sideways)
The guillotine door, in addition to up-down shifting, can also be opened sideways.
Sideways opening serves only to service the insert (cleaning the glass pane, etc.). It is not intended for everyday
use.
In order to open the door:
• pull tabs protruding in the corners of the guillotine - release the door from the handle;
• open slowly pulling the door towards you;
After opening the door, you can start maintenance or cleaning the cartridge.
ATTENTION!
The doors open at an angle, the attempt of wider opening by force may lead to their damage.

The fireplace insert must be installed by a qualified person or company and commissioning checks must be
performed by a master chimney sweep and a fire prevention specialist.
The installation of the fireplace should be performed in the following order:
•connection of the fireplace to the chimney and assembly of the air intake;
•putting the fireplace into use and observing its functioning for the purpose of detecting defects and
anomalies (for about 2 weeks);
•assembly of the encasing.
6.1. Transport
Transport and handling:
•the insert is delivered as an assembled unit, fastened to a palette and wrapped in stretch foil;
•the fireplace should be transported in a vertical position;
•after unpacking, check the insert for any transport related damage;
•unpack the insert in the vicinity of the installation site; exercise caution when moving the insert (preferably
on a cart) (paying special attention to the door and glass);
•the packaging materials of the fireplace insert are not toxic or harmful and should be recycled or stored by
the User;
•to facilitate the assembly of the fireplace in hard-to-reach places, the ceramic lining (shielding the hearth)
can be removed; after the assembly, every element made of ceramic concrete should be correctly placed
in its intended location.
6.2. Recommendations concerning the floor:
•the floor must be made of non-flammable material with a minimum thickness of 30 cm; a safety area of least
50 cm must be ensured in front of the fireplace door, and of at least 30 cm from the edges of the door.
•the floor in the place of the feet adjusting the height should be adequately higher so that it is possible to
install the air intake pipe in the fixing hole.
6.3. Chimney duct
The fireplace insert must be appropriately selected to match the cross section of the combustion gas duct (flue
pipe) and the height of the flue.
The cross-sectional area of the flue and of the combustion gas duct is calculated in accordance with the following
formula:
where:
F –cross-sectional area of the flue and of the combustion gas duct [m2];
Q –rated thermal input [kW];
h –the height of the chimney [m].
In accordance with the applicable provisions of law, the flue may not be smaller than 14x14cm or its diameter must
be 15cm. Inserts with a higher thermal input require a flue with a larger cross section. The cross section also
depends on the height of the chimney.
The fireplace should be connected to the combustion gas duct or the vertical duct in accordance with the
applicable national standards.

WWW.HITZE.PL
FIREPLACES | STOVES | BIO and GARDEN HEATERS | ACCESORRIES
Page 11
The chimney draught should be as follows:
- minimum draught –6 ± 2 Pa;
- MEDIUM, RECOMMENDED DRAUGHT –12 ± 2 Pa;
- maximum draught –15 ± 2 Pa.
NOTE:
To ensure the correct functioning of the insert, there must be a correct chimney draught in the connector of the
flue pipe:
•the insert will not function properly if the chimney draught is not sufficient, resulting in excessive soot
deposits on the glass and in combustion gas ducts and reducing the total thermal power of the insert (due
to which combustion gases may escape to the room);
•if the draught is too strong, the burning process may be too intense, causing high consumption of fuel and
resulting in permanent damage of the insert.
The chimney should be regularly inspected by a chimney sweep company.
6.3.1. Connection of the chimney ducts:
•before installing the fireplace insert, the chimney ducts and its technical parameters and condition must be
inspected and approved by a chimney expert;
•the fireplace insert may be only installed after the flue pipe has been inspected and approved by a chimney
expert.
The chimney duct must satisfy the applicable national or European standards.
The fireplace insert must be mounted and connected to the chimney in accordance with the supplied Operation
and Installation Manual (together with deflector plates - if they are to be used, and the insulation of the flue pipe).
The manufacturer does not recommend the assembly and installation of the appliance by the user on his or her
own. To make sure that the insert is installed and put to use in a correct and safe manner and to satisfy the
guarantee conditions, the user should have the appliance installed and put to use by a qualified installer or an
installation company. The installer is required to confirm in the guarantee card (signature and stamp) that the
fireplace has been installed in accordance with good building practices and the applicable legal provisions. If the
above-mentioned activities are not performed, it will invalidate the guarantee.
6.3.2. The combustion gas outlet system should have the following features:
•the cross section of the flue pipe may not be smaller than the cross section of the chimney duct and it may
not become narrow towards the chimney (between the flue pipe and the chimney, the diameter can be
increased through the use of mounting adapters);
•the path of the combustion gas duct should be as short and straight as possible (bends increase flow
resistance and facilitate the accumulation of condensed moisture);
•it is forbidden to connect the insert to the same chimney duct with another heating device;
•the fireplace insert should be connected to its own chimney duct;
•the combustion gas duct may not have more than two inclinations of 45° when its length does not exceed 5
m and of 20° when it is more than 5 m long;
•the combustion gas duct must be made from non-combustible materials and it must be thermally
insulated;
•the insulation of the flue pipe must ensure fire resistance for at least 60 minutes;

WWW.HITZE.PL
FIREPLACES | STOVES | BIO and GARDEN HEATERS | ACCESORRIES
Page 12
•the flue exit should be followed by a straight pipe with a minimum length twice as long as the diameter of
the fireplace flue;
•the connector must be leak-proof;
•the end of the chimney should ensure a trouble-free outlet for combustion gases and it should be placed at
least 60 cm above the highest point of the roof;
•the connectors must be made from stainless, heat-resistant steel 1.4401 (316) or fireplace steel, painted
with a special paint. The metal sheet must have an appropriate thickness (heat-resistant and stainless steel
must be 1mm thick, fireplace steel - 2mm) and be resistant to high temperature, the acidity of combustion
gases and condensed moisture.
Enough room should be left when building the enclosure of the fireplace insert so as to ensure an easy access for
the purpose of cleaning the insert, the flue pipe and the chimney.
Figure 6. Diagram of connecting the insert to the chimney.
(A - rear air inlet; B - bottom air inlet)
6.4. Ventilation of the insert:
•fresh air must be supplied to the combustion chamber from outside (if the amount of air is too small, it will
hinder the burning process and toxic combustion gases may be produced, including carbon monoxide);
•the fireplace must be encased in such a way so as to ensure a supply of fresh air from the outside (by using
an air inlet pipe with a diameter of 150÷200mm);
•it is estimated that about 8m³ of air is required for burning 1kg of wood;
•in the case of using a system of distributing air to other rooms, it is essential to ensure the return of cooled
air to the room where the fireplace insert is installed so that the air can circulate freely (otherwise, the
work cycle of the fireplace insert may become disrupted, which will hinder the distribution of warm air);

WWW.HITZE.PL
FIREPLACES | STOVES | BIO and GARDEN HEATERS | ACCESORRIES
Page 13
•when choosing the site for the appliance and during its installation, attention should be paid to ensuring
the correct circulation of air and a proper balance between air inflow and outflow in the room;
•ventilation must be provided in the room where the fireplace is installed;
•the ventilation of the insert should have a cold air inlet and a warm air outlet (ventilation should be
provided for the convection space to make sure that air comes into contact with the heatable parts of the
insert and enters the flue pipe).
6.5. Installation of the insert
The appliance must be installed in accordance with the applicable provisions of the building law.
The fireplace must be installed and assembled by qualified specialists.
6.5.1. To ensure the correct installation:
•the insert must be placed at a safe distance from any flammable materials (the walls or other surfaces
surrounding the fireplace may have to be secured);
•the encasing should ensure easy access to adjusting handles and operating handles (it should be possible to
assemble and disassemble the insert without having to dismantle and damage the encasing);
•installation of the fireplace insert is forbidden in bedrooms, bathrooms and rooms where there is another
heating device without an independent air supply;
•Trinity insert are uniform construction and do not require additional supports;
•the fireplace is equipped with regulated feet for adjusting the height (levelling) of it (with an adjustment
range of up to 4 cm);
•if the fireplace has to be raised above the adjustment range of the feet, make a brick base and place the
fireplace on it (do not remove the feet as they are needed for levelling purposes);
•incorrect levelling of the fireplace will hinder the functioning of the door (it will not close properly);
•an inlet vent (inspection window) at the front or side is recommended, in the lower part of the encasing of
dimensions 20cmx30cm - allowing easy access to the throttle mechanism at the front and bottom of the
insert;
•If there are no inspection windows, the manufacturer is not liable for damage to the cartridge during the
service and warranty works.

6.5.2. General recommendations concerning the housing:
•the fireplace insert can be placed anywhere, as long as it is positioned at an appropriate distance from the
insulation and the housing;
•the supporting structure and the housing of the fireplace insert must be made from non-flammable heat-
resistant materials ;
•the housing should be made from non-flammable materials;
•distance between the insulation materials and the insert should be at least 10 cm;
•there should be a warm air outlet vent in the housing, positioned 80cm from the ceiling (in the case of
flammable materials);
•during regular use, the housing of the fireplace extends (due to the heat), therefore there should be tiny
gaps between stone, marble or ceramic elements;
•preferable insulation material should be resistant to temperatures over 500⁰C;
•preferably, no insulation should be provided for the flue (it will ensure more effective dissipation of heat
into the room);
•it is recommended to create an isolated decompression chamber with separate ventilation vents. Thanks to
this, the ceiling is better protected against discoloration and cracking;
•the housing cannot lean on the fireplace;
•the thickness of the insulation depends on the thermal conductivity coefficient λ (the ability of a material to
conduct heat) and heat resistance of a given material;
•in the housing of the insert, there should be a cold air inlet vent (at the bottom of the encasing) and a
warm air outlet vent;
The λ coefficient is specified by the manufacturer of the insulation, e.g. for mineral wool it is 0.035-0.045.
The lower the λ coefficient, the better the insulation (“thermal insulation in the room”)

Screw the cover at the back of the insert ad tighten the
air inlet at its bottom.
6.7. Wall mounting.
The insert is equipped with 4 brackets which after mounting to the wall are to ensure the stability of the
insert. The choice of the manner of mounting the brackets to the wall should be made on your own, taking into
account the loads that will affect the insert and the mounting site.
We recommend installing with the use of a chemical anchor and an M12 threaded rod.

7. START-UP
After the fireplace insert has been mounted and connected to the chimney, the first start-up of the fireplace must
be performed by an installer or a qualified service technician.
As part of the start-up procedure, the installer should show the User how to operate the fireplace correctly.
The installer is obliged to refuse to put the fireplace into use if he or she finds any assembly-related irregularities
which make it unsafe to use. A correctly performed start-up should be confirmed in writing in the guarantee card.
7.1. Getting ready for the start-up
Before lighting the fireplace for the first time, it is necessary:
•to remove any labels, paper stickers and accessories from the body of the insert or hearth to eliminate the
risk of fire; the same applies to transport safety devices;
•to check if the deflector/s, ceramic fittings are mounted correctly and were not dislodged from their
correct position during installation (any discovered mounting errors must be corrected). Non-removal of
such errors may hinder proper functioning of the fireplace insert. In the case of inserts with multi-pane
glass doors, it should be checked if particular glass panes did not become loose during transport or use;
•to check the operation of:
−mechanism regulating the air inflow into the combustion chamber (cold air inflow throttle);
−front door closing mechanism (hinges, handle);
•to check the correctness of the installation in accordance with this Operation and Installation Manual and
the applicable legal provisions, especially in terms of the following safety-related issues:
−is the fireplace levelled
−is a proper ventilation system provided for the room and the fireplace
−does the air intake ensure unobstructed flow of air from outside and into the room
−is the connection to the chimney sealed properly
−has the fireplace encasing been built correctly

7.2 Lighting the fireplace
Before lighting the fireplace, please do the following:
•arrange a stack of firewood in the hearth, starting with larger pieces of wood, followed by medium-sized pieces
of wood and then by small chips of wood for fire lighting –light it with a match;
•set the primary air regulator in the fully open position (POSITION 2);
•after lighting the fire, the door of the fireplace must be closed;
•when the fuel is burning properly, adjust the burning process with air regulators to ensure a steady and calm
rate of burning (setting the mechanism between 3 and 4 position will direct a small part of primary air under
the grate of the fireplace, whereas the remaining part of the air will be directed to the combustion gases after
burning system; opening of the air intake mechanism in POSITION 3 - fuel will burn with high intensity);
•it is recommended, at the final stage of burning, to open the door and move the remaining embers onto the
grate, using a poker, so that all fuel is used up;
•test the functioning of other components of the installation (when the fire is lit for the first time).
ATTENTION:
Because a large amount of air is fed under the grate and to the air curtain and after-combustion system, too much
fuel in the combustion chamber causes the production of a large amount of wood gas, which results in a temporary
smoke of the glass.
The maximum shift of the throttle to the right causes a complete shut-off of the air supply to the combustion
chamber, which results in a gradual extinguishing of the furnace.
If necessary, the grate is unblocked with a poker or a grate lever (if the insert has a movable grate).
During the first hours of using the insert, it is recommended to load the fireplace with a small amount of fuel, i.e.
up to 50% of the normal load.
When the fireplace is lit for the first time, water may condense on the internal walls of the combustion chamber.
This phenomenon is normal and is caused by the condensation of water vapour contained in combustion gases. It
should disappear after the combustion chamber has heated up.
If combustion gases escape from the fireplace chamber, the position of the combustion gas throttle should be
adjusted and the chimney draught should be increased.
Before the next lighting, clean the hearth from remaining ash.
