keep it in plasstic cover and to hang it on visible place on the wall to be reached by
technician, who will perform service in your boiler room.
Device for pellet burning, PELH30A has to be connected to boiler that is suitable for
heating with solid fuel. Suitable boiler is ATTACK PELLET 30, resp. 30A. Boiler door
and connections between boiler and chimney have to be airtight.
Overpressure in combustion chamber has to be min. 5 Pascal (0,5mm of water column,
resp. 0.05hPa).
The PELH30A appliance is intended for combustion of wood pellets, it cannot 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
Warning sign will appear in this manual to prevent possible risk at breaking the
instructions. In this manual, two types of warning signs are used:

Technical description
PELH30A is designed on basis of fuel feeding by principle of falling, when the pellet fall
by self-force from pellet feeder through inlet hose and inlet tube on the grate, where the
combustion runs.
PELH30A has electrical ignition that automatically ignites pellets fallen on the grate.
Ignition begins only after the thermostat gives instruction to burner.
PELH30A has own built-in thernmostat (for the case that there is no boiler/external
thermostat installed, resp. combined connection with room thermostat). Its temperature
sensor has to be inserted into suitable case in water jacket of the boiler. The on- and off-
temperature is adjustable via menu buttons of the burner. Information about actual
operation data is given on display.
NOTE: Head for boiler temperature sensor must not be treated with contact liquid or
paste.
PELH30A has production pre-set range of output 14-30 kW and three degrees of output:
1 (14 kW), 2 (22 kW) and 3 (30 kW).
Selected output degree is projected on display during operation. It is possible to change
output via menu buttons of burner and information on dipslay. It possible to change range
of output in two levels - from 8 to 12kW and from 14 to 30kW and according to this there
are three degrees of output from 8 to 12 kW or from 14 to 30kW in the extended menu.
PELH30A has own self-cleaning grate mechanism. When thermostat reaches adjusted off-
temperature, cycle of burn-out begins and afterwards the grate moves out and it is cleaned
by scraping. This enables longer time of usage, during which it will not be necessary to
remove burner from boiler. Amount of pellets that is possible to combust before the ash is
removed is given by size of the boiler´s ashpan. It is possible to prolong this interval by
automatic ash removal from boiler into ashpan outside of the boiler. Burner is equipped
with control system that regulates gear of the ash removing feeder.
Convectional parts of boiler have to be cleaned in regular intervals to keep high efficiency
of heating.
PELH30A is intended for combustion of wood pellets with diameter of 6-10 mm.
Burner PELH30A is made under industrial norms and prescriptions and it was tested and
approved in conformity with directives about low voltage appliances as well as with
directives about electromagnetic interference.

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

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

How to install pellet burner
Pellet burner PELH30A can be installed only by qualified, specifically skillfull personnel.
Burner door are from production mounted to boiler.
Put the burner on door screws and fasten it by nuts (B). Connect inlet pipe to pellet feeder
under the required angle. Fix inlet pipe into stable position and fasten clamping screws.
Install pellet container and pellet feeder. There should be height gap between feeder´s
opening and inlet pipe of min. 400mm. In horizontal position there should be gap between
inlet pipe and feeder´s opening of min. 1500mm (i.e. not vertically aligned).
Fill container with pellets and connect feeder into mains socket (230V~). Let feeder run,
until you reach continual pellet feeding. We recommend to fix plastic bag to feeder´s
opening to collect falling pellets. Disconnect feeder from mains socket. Install inlet hose
between feeder´s opening inlet pipe and set length of the hose.
Hose should not be straight, nor too incurbed, to prevent pellets from stucking and
cumulating. Connect feeder into burner´s socket.

15
Burner start
By turning the boiler´s main switch on is the burner automatically turned into emergency
regime. Burner is put into operation by turning the burner´s switch on and by turning
boiler´s thermostat into position adequate to required boiler temperature. Following
demand for heat supply is the burner ignited and burns pellets, until the thermostat gives
instruction to stop.
Burner is alternatively controled by thermal boiler sensor connected to TS1 inlet on the
right upper side of the circuit board. Make sure, that connection is fixed into one position.
Burner stop
Burner turnes off by turn-off-signal of the boiler thermostat, by turning off the burner´s
switch (emergency regime, or via Burn-down = Final combust. ) initiated per menu.
Emergency stop
NOTE:
In case of emergency can be burner turned off by the main boiler switch and by plugging-
out of the boiler´s mains cord from mains socket.

16
Cleaning and maintenance
It is necessary to clean the burner after every consumption of 2000kg of pellets. It is based
on presumption, that boiler accepts appropriate amount of ash and quality pellets are being
burned.
Moreover, it is recommended to sweep exchanger´s parts of the boiler at least twice
a month.
1. Clean pellet inlet into burner by brush for bottles or other suitable tool.
2. Scrape the ignition board and the grate and clean holes in the grate.
NOTE:
Keep ash in closed containers from uninflammable material.
Maintenance once a year or in case of need (by qualified person)
Start burn-down by menu buttons and wait, until the fuel in burner burns-out. Turn the
burner off by burner switch and by the main switch, plug out mains cord of the boiler from
mains socket. Open door with burner to cca 90°.
1. Put down burner cover and wipe photocell by rag and soft abrasive agent (tooth paste)
Be carefull by flat cable of display and buttons!
2. Clean air wings of the fan. Most suitable is to blow them with compressed air.
3. Screw out the scrape and ignition board.
4. Clean space behind the ignition board.
5. Scrape ignition board and scraper.
6. Brush grate utterly and clean holes in the grate.
5. Mount all parts back.
6. Clean container and pellet feeder from dust and small dirt.
7. Check state of inlet hose for pellets.
8. Put pellet feeder into operation by plugging of feeder´s mains cord into mains socket
(230V~) to fill it with pellets.
9. Set feeded amount of pellets.

17
Trobleshooting
Burner turned off.
Check, which alarm was indicated on display.
If display is black and without text, check thermal fuse of the boiler. If there is no error,
probably is only the burner´s thermal fuse turned off. To start again, turn energy supply into
burner off, remove cover and press small button between overheating fuse connections.
Thermal fuse is placed directly in the fuel-inlet tube. After restart, mount the cover back
and turn on the energy supply. Thermal fuse of the burner is switched off at the temperature
of 93°C.
