Important information
Please, read this manual before starting the burner. The burner has to be installed by the
approved and trained technician.
Keep this instruction manual at a suitable place in the boiler room. We recommend to keep it in a
plastic cover and to hang it on a visible place on the wall to be reached by a technician, who will do
the service in your boiler room.
The PELH30A device for pellet burning, has to be connected to the boiler that is suitable for
heating with solid fuel. Boiler door and connections between the boiler and the chimney have to be
airtight.
Overpressure in the combustion chamber has to be min. 5 Pascal (0,5mm of the water column, resp.
0.05hPa).
The PELH30A appliance is intended for combustion of the wood pellets and it must not be used
for combustion of other fuel types.
The PELH30A device can be installed only in the boiler room, in conformity with prescriptions of
the local fire protection / construction institute.
Warning sign
The warning sign will appear in this manual to prevent possible risk by breaking the instructions. In
this manual, two types of the warning signs are used:
WARNING points out the dangerous situations by breaking the essential measures.
NOTE points out the less safe actions that may lead to the safety threat or to damage of
property.
Technical description
The PELH30A works on basis of the fuel feeding by the principle of falling, when the pellets fall by
from the pellet feeder through the inlet hose and the inlet tube on the grate, where they are burned.
The PELH30A has an electrical ignition that automatically lights the pellets fallen on the grate.
Ignition begins only after the thermostat gives instruction to burner.
PELH30A has an own built-in thermostat. Its temperature sensor has to be inserted into suitable
case in water jacket of the boiler (See the picture). The on- and off-temperature is adjustable via
menu buttons of the burner. Information about actual operation data is given on display.
NOTE: Head of the boiler temperature sensor must not be treated with a contact liquid or
paste.
The PELH30A is set in production to the output range of 14-30 kW and three degrees of output:
1 (14 kW), 2 (22 kW) and 3 (30 kW).
The selected output degree is dipslayed during the operation. It is possible to set the output via the
menu buttons of the burner and the information on display. The range of output can be changed in
two levels - from 8 to 12kW and from 14 to 30kW - according to this there are three degrees of
output from 8 to 12 kW or from 14 to 30kW in the advanced menu.
3
The PELH30A has an own self-cleaning mechanism of the grate. When the thermostat reaches the
adjusted off-temperature, the burn-out cycle begins and afterwards, the grate moves out to be
cleaned by scraping. This enables longer time of use, without need to remove the burner from the
boiler. The amount of pellets which can be combusted before the ash is removed, is determined by
the size of the boiler´s ashtray. The burner is equipped with the control system that regulates gear of
the ash removing feeder.
Convectional parts of the boiler have to be cleaned in regular intervals to keep the high efficiency of
heating.
The PELH30A is intended for combustion of the wood pellets with diameter of 6-10 mm.
The burner PELH30A is made in conformity with the industrial norms and prescriptions and it was
tested and approved in conformity with the directives about the low voltage appliances as well as
with the directives about the electromagnetic interference.
Dimensions / Contents of delivery
The PELH30A is delivered in a paper box filled with polysthyrene to improve stability. If the box is
damaged, check the burner for possible damage by transport. Claim of the damage by transport has
to be registered by a spediteur.
The paper box ought contain the following items:
1 pc. Burner PELH30A
1 pc. Inlet tube with emergency thermostat of back-burning

Description of function
NOTE: The PELH30A works with the built-in digital thermostat, resp. with additional
room thermostat. In both cases, the burner has to be connected through fuse against boiler
overheating.
Normal start-up
When the thermostat gives instruction to the burner, the ventilator starts and the photocell controls
the fire. If there is no fire, then comes the instructi on to blow the burner through. Afterwards,
pellets start to fall into the burner within the period stated by the control system and the ignition is
activated.
After the phase of fuel feeding for ignition is finished, the control system waits for signalization of
fire from the photocell.
When the photocell recognizes the fire, small amounts of pellets fall within the transition period.
Duration of this depends on the output level set on the burner. Pellet supply is gradually increased,
until the necessary fuel amount for the required output is achieved. This amount is further delivered
into the burner, until the operation thermostat gives instruction to stop.
This signal stops the pellet inlet, while ventilator continues to supply the air into the burner.
When the photocell recognizes burn-out of pellets, the blow-through of the burner begins.
According to the adjusted delay, the burner is cleaned after the fuel burns out - the grate moves out
towards the scraper and the ash with the unburned elements falls through the front wall of the
burner´s bottom into the ashpan.
After the grate slides back, the burner waits for the new signal from thermostat.
NOTE: the unit for the grate moving is very strong and it might cause a threat. Never put
any body parts or foreign articles into the burner, while it is working.
Normal start-up, when there is still fire in the burner
If the photocell recognizes the fire during the beginning phase (e.g. after the short-time current
shortage), the control system directly begins the transition-phase and the pellet burner continues to
operate as by normal start. (see above)
Normal start-up, when the control system does not recognize the fire
The normal start-up process follows, also when the control system does not receive the fire signal.
Shortly after, the system begins the new start-up trial with fuel amount reduced for ignition by
approximately 45%. This amount can be reduced within the whole ignition period. These
parameters are adjustable only by the trained person in service menu. If the second trial fails, all
functions are turned off and the alarm is activated. This alarm is indicated on display.
NOTE: Make sure that the sufficient flue gas temperature was reached. It has to be at least
60°C - one meter under the chimney top. If the temperature is lower, consult it with your
chimneyer. The flue gas temperature lower than 60°C during the combustion process increases risk
of the chimney damage by condensation.

How to use the pellet burner
The pellet burner needs air for combustion, so the boiler room has to have the air channel . The air
channel for the air inlet must have at least the same surface as the chimney and it must be opened.
The pellet burner must not be started, until it is safely approved that the smoke can freely go
through the boiler and the chimney into the environment.
Pellets are supplied into the PELH30A by the external feeder connected to the pellet container. For
better function and the most balanced feeding, the feeder should be fix ed under the angle of 45°.
The feeder should be able to feed at least cca 10 kg of pellets per hour of the continuous operation /
demand for pellet supply.
Pellets have to be stored in a well ventilated room without moisture or in a specially adjusted
container.
NOTE: The PELH30A consists from the components of high quality that must not be
replaced with the spare parts of lower quality. If the components are repl aced with other than the
original spare parts, the validity of warranty expires.

Nothing in the burner is started, burner waits for the signal from
thermostat to start.
The fan starts to operate and when the photocell recognizes the
value under 5%, the program continues.
The fuel ration for heating up is supplied into the burner and
program waits for the „fire“ signal from photocell.
The transition phase begins, when the photocell and the control
system recognize the fire. Small, gradually increased amounts of
pellets are feeded into the burner, until the required pellet ration is
achieved.
The combustion phase runs, until it is interrupted by the thermostat.
The thermostat interrupted the combustion phase and the burner
begins the phase of burning-out.
The grate moves out and when it is out completely, the fan runs at
full rotations, until the grate moves back.
After expiration of the set period (e.g. 6 hours), the burner starts
auger for ash removing for adjusted time (e.g. 3 minutes).
Step 8: Comeback into the standby mode.
