1. General information
Smart Fire boiler is and advanced heating system burning pellets.
The system includes: thermo-control system, a system facilitating manual cleaning of the heat
exchange, advanced ceramic burner, automatic system of burner clearing, and an automatic lighter.
The boiler can provide heat to the central heating system in a building, with pump or gravitational
circulation, as well as hot tap water.
Smart Fire has been rated as low-temperature system and therefore needs no registration with the
local authorities in most jurisdictions.
Solid fuel boilers operating in a closed circuit are sometimes subject to a limited technical
supervision. Once the boiler is installed, the user may need to notify the local supervising
authorities before launching operation.
2. Recommendations
Initial launch and the all relating tasks and any service work can only be completed by the
manufacturer's or authorised service team.
Only fuel specified herein can be burned.
The boiler must be regularly maintained as specified in this Operation Manual.
Always observe the requirements set in this manual
Failure in submission to the provisions of the manual will result in loss of warranty and exempt the
manufacturer of responsibility of the outcome of the system's operation.
You shall observe the general rules applicable to heating technology to protect the system of
legionellosis.
3. Safety rules
Read these rules before launching operation. Failure in submission to the instruction may lead
to: casualty, loss of health, life hazard, damage to the system, the heating installation and the
HKS LAZAR str.4
building!
Only persons holding necessary licences, knowledge, skills and equipment can be trusted with
assembly of the boiler.
The installation must satisfy all standards and rules in force and the principles of construction craft.
The boiler can only be operated when both the boiler and the heating installation are in perfect state
of repair. Breaks, defects and disturbances in operation must be immediately reported to the relevant
authorities.
Before launch and then regularly every six months, check if the heating system contains enough
water.
Never open the inspection openings when the boiler is working as this may release dust and exhaust
that next can ignite and explode,
Never attempt any repairs or reassembly,
Never remove the covers as movable pieces and electric devices are installed behind.
Extinguish the boiler and wait till it cools down before start of any maintenance work with the
boiler.
At least once a month check the doors and the water inlets and outlets for tightness.
At least once a year check operation of the STB fuse.
Facilitate the boiler room with a sign prohibiting smoking and use of fire.
Ventilating system must be operable and satisfy all relevant requirements.
Operable extinguisher must be available in the boiler room.
The boiler room must be secured against entry of unauthorised persons, in particular children.
Never remove or disable any safety or measurement devices.
Use gloves, dust mask and overalls when clearing ash and cleaning the boiler.
The boiler must only be installed in the premises designated thereof and satisfying the applicable
requirements.
Extinguish the boiler when fuel is delivered.
If the temperature of tap water has been set up above 60ºC, warrant admixture of cold water as this
creates risk of burning injury.
Facilitate proper air removal off the boiler and the heating system.
Use only manufacturer's spare parts.

5. Boiler construction
Smart Fire boiler has been designed as compact structure. Most of the boiler pieces are hidden
behind the covers which protects them against elements and mechanical damage.
Smart Fire boiler, its dimensions and placement of the connectors to the heating system and the
chimney outlet have been shown at the fig. 1. Figures 2-4 show the boiler specifying its main
systems.
There two main elements within the Smart Fire box: the boiler's body and the fuel supply system.
The body includes: a collector. a steel heat exchange, the combustion chamber and the ash tray
chamber. Inside the steel heat exchange you will find vertical hot gas pipes and the deflector. The
exchange features a manual cleaning system. On top of the exchange rest the upper collector and
the ceramic deflector made of vermiculite, The exchange rests on the lower part of the body which
consist of: the combustion chamber, the ash tray chamber, the exhaust collector, A ceramic burner
fits inside the combustion chamber. The burner is fit with an automatic clearing system. Fuel falls
down from the auger feeder having its outlet placed above Burner's ash falls from the combustion
chamber to the ash tray in the chamber underneath. An exhaust collector is placed behind the ash
tray chamber. Exhaust of the combustion is sucked to the exhaust collector with an outlet fan and
then directed to the flue collar.
The other main system supplies fuel. It is integrated in the external box of the boiler covers. These
includes: fuel container and the auger feeder with a moto-reducer. Fuel falls from the main fuel
container to the auger feeder. This in turn, pushes fuel to the burner in the combustion chamber. The
HKS LAZAR str.7
boiler body connects to the fuel supply system with the collar of the auger feeder.
Two covering panels are fixed in front of the boiler. You can access the combustion chamber and
the ash try chamber with the pair of inspection doors under the bottom panel. The upper panel
makes the upper part of boiler body. A control display showing current status of the boiler is fixed at
the front wall of the fuel container.
The inlet and outlet of the heating system water are located at the back wall of the boiler. These are
threaded pipe ends with a 1¼ " internal thread. The back wall also holds the exhaust collar
connecting the boiler to the flue system. The placement of the connectors has been detailed on the
fig.1. An outlet fan is fixed to the back wall next to the exhaust collar. Amount of air flown by the
fan is controlled by the system controller. A thermocouple monitoring exhaust temperature is fixed
in the exhaust collar.
The external covers and the body are insulated with mineral wool to reduce heat loss in operation.
The covers are made of steel sheets covered with high quality powder paint.
