1. Description and advantages of automatic hot air pellet stove of

series “Pony”.

The unit of series “Pony PS9” is steel-plate hot air pellet stove, which uses
solid biomass fuel in shape of pellets. The stove is designed for local heating
of domestic and office spaces. The stove utilizes wood pellets, as well as
other type/shape of biomass; the resulting heat energy from thermo-chemical
conversion (i.e. combustion process) is transmitted from the heat-exchanging
surfaces to the surrounding air, both by convection as well as thermal
radiation. The model “Pony PS9D” is equipped with additional hot air duct
for heating more that a single room.

The complete set of the pellet stove consists of:

 Automatic hot air pellet stove– 1 ct;
 Battery – Toshiba 23A, 12v, V23GA – 1 ct;
 Remote control - 1 ct;
 Plastic heels M10 X 43 - 4 ct;
 Handle - 1 ct;
 PC power supply cable AC 220V - 1 ct;
 Users guide for automatic hot air pellet stove of series “Pony” – 1 ct;

The unit could utilize following types of fuel:

 Wood pellets, having diameter 6 mm, covering the requirements of

class ENplus-A1 of standard EN 14961-2:2010;

 Other solid biomass based pellets, but confirmation for these fuels

utilization need testing and approval by stove’s producer company
laboratory;

The unit is equipped with:

 Steel plates welded heat exchanger for heating-up the surrounding air;
 Flue gas fan;
 Fan for forced convection and heating-up of the surrounding air;
 Daily fuel hopper with capacity of about 19 kg;
 Programmable operating module, which controls the functions of the

unit and is adjustable to the specific needs of the client;

 Ash container with capacity of 0.5 kg;

Page. 6/61

 The model “Pony PS9D” only : the unit is designed with additional air

flow control system, allowing hot air distribution control and hot air
supply duct fir heating another room;

utilization is less dependent on the world fuel market trends and
practically the heat energy price is competitive to the conventional energy
sources;

 The stove is automatic and the thermal comfort achieved is close to that,

originating from exploitation of fully automatic heaters, (for example
running on liquid or gas fuel, as well as electric heaters). The stove is
equipped with integrated programmable room thermostat (daily, weekly
and weekend programs);

 The unit is equipped with automatic fuel ignition system and performs

burner’s ash cleaning procedure, controlled by the electronic module;

 Remote control of the operating mode of the stove;
 The stove utilizes wood pellets, covering the requirements of class

ENplus-A1 of standard ENplus, or other standards as ONORM M7135,
DIN 51731 и DINPlus;

 High efficiency;
 Low pollutant contents in the flue gases;
 Automatic fuel feeding system, transported from the built-in “daily”

hopper to the burner;

The European wood pellets standard EN 14961-2:2010
defines wood pellets certificate ENplus for pellets, utilized
in boilers, stoves and appliances for domestic heating
systems. The certificate EN-B is applied for pellets, utilized
in industrial boilers. In principal the ENplus standard defines

two quality classes: А1 и А2. The class А1 is highly
restricted, considering the ash content. The class А2 the limit of the ash content
of the wood pellets is higher – up to 1.5%. For industrial boilers the certificate

EN-B is applicable, which defines fewer restrictions on the pellets quality.

3. Description of the construction of hot air automated pellet

stove “Pony PS9”

The heat exchanger of the stove complies with the acting requirements for

such kind of units, defined in operating norm: EN 14785:2006 – „Heating units

for dwellings, utilizing wood pellets. Terminology, requirements, testing and
marking”.

The unit consists of:

 Main part of the unit is heat exchanger. In the combustion chamber of

this exchanger is mounted specialized grate burner, designed for
horizontal fuel feeding;

 The heat exchanger is welded construction of carbon steel plates. The

lower part of the exchanger is designed as combustion chamber. The
burner is mounted in this chamber and under is the ash container.

 Combustion chamber: It is designed to provide conditions for optimal

burning process and helps for complete combustion of the fuel. The
chamber is closed by a door with heat-resistant (ceramic) glass, giving the
possibility to see the combustion process and also provides direct heat
radiation to the surrounding objects.

 Stainless steel burner, mounted in the combustion chamber of the heat

exchanger;

 Ash container, positioned in the lower part of the combustion chamber,

below the burner;

 Fuel hopper is mounted right behind of the stoves’s burning chamber. In

the hopper (in the center and inclined) is mounted a fuel transport auger;

 Fresh air for burning is provided by a pipe. The air for burning needs to

be with room temperature. Do not connect the pipe directly to the outside
of the building;

 Flue gases exit duct is positioned in the lower rear side of the unit (after

the flue gases fan, concerning the flue gases flow direction), utilized for
forced flue gases extraction;

 Hot air duct, which allows the heated ambient air to be convected to

another room – this is valid for model “Pony PS9D” only

. The size of the
duct is shown in Table 2.2. The hot air distribution is controlled by a level
drive flap, installed in the front upper section on the unit;

 Control unit it is placed in a cold zone of the stove and provides save

function of the appliance. The control is equipped with a lithium battery,

Page. 12/61

which has live time of 5 years – it is used to memorize the settings of the
control module in cases of interrupted main power supply. In order to
maintain safe function the stove is supplied with a pressure switch for
monitoring the functionality of the chimney. In cases of malfunction of
the chimney, the pressure switch stops the stove immediately, preventing
damages to the appliance and emergency situations. Also the stove is
monitoring the flue gases temperature. In cases of increased temperatures,
the controller of the stove goes in minimum power, or in case of excessive
values, it shuts down the unit;

 Interface panel is used for set up of the control unit. And to monitor the

work parameters and massages;

 The heat exchanger, fuel hopper and other modules of the stove are

covered with decorative covers , powder painted in different colors;
