Boiler start-up
(USER/INSTALLER)
ATTENTION!
The controller settings can be regulated depending on the variety of the existing
central heating systems, heating requirements of the bulding and calorific value of
the fuel. The boiler parameters are set by the user and it is not serviced by the
company.
Before starting fire in the boiler, make sure that the central heating installation has been
installed properly and filled with water- until it flows over through the overflow pipe from the
expansion vessel.
For the best results, the installation should ideally be filled with softened water/ chemically
treated water, distilled water or rain water.
Moreover, it must be checked whether the retort burner has been cleaned from residue of
unburnt fuel, ash and slag from the previous burning and whether ash has been removed from the
ash pan.
Close all doors for the duration of firing up. After a stable flame is obtained, switch the regulator
to automatic work, causing the fuel feeder and fan to activate automatically.
Set the desired boiler work temperature, typically 70-
80 ºC. From now on, the boiler will work
automatically, as per the settings configured by the user on the regulator according to the
regulator's instruction manual, intended for the user and attached to this instruction manual.
Inspect the burning process periodically through the observation door. Ash and slag from the
burnt fuel gradually fall into the container in the ash pan, meaning that the burner is self-cleaning.
In the event where a piece of slag is suspended between the boiler’s wall and the burner, remove it
using a poker or hook.
The regulator protects the boiler against: exceeding maximum water temperature in the boiler,
blowback of embers into the fuel feeder, and shuts down the entire system in the absence of fuel.
A sensor reacting to flame reversion from the burner to the feeder is located on the feeder's
pipe between the retort burner and fuel dispenser. In such a case, the fan is shut down immediately
and the continuous feeder work is initiated until the burning or smoldering coal is pushed from the
feeder and retort burner into the ash pan.
The boiler’s user should read the user’s manual of the microprocessor
-based regulator
thoroughly.
After starting a cold boiler, or at first start-
up, the boiler can “sweat”. It may seem like it is leaking.
In such case, you must perform intense combustion (70-
80ºC) in order to dry and warm th
e boiler
and chimney vent through, even for 2-3 days.
To ensure longer boiler operation, it advised to keep the fumes temperature 180C above the
outside temperature and the water temperature in the boiler should not be lower than 60C. In such
situation, keeping an appropriately low temperature in the radiators in the autumn-spring season
can be done, amongst others, by:
Properly selecting the boiler to the heated rooms.
Using, between the infeed and return of water, three- of four-way mixing valves, operated
manually or automatically.
Maintaining the continuity of the burning process requires periodical replenishment of fuel in
the dispenser. The frequency of replenishment depends on the intensity of the burning process and
should be determined individually based on experience. Replenishment is done every 1-3 days on
average. The ash pan is to be emptied with the same frequency.
An insufficient amount of fuel in the dispenser causes dust to rise when the cover is opened
while the boiler is working. The absence of fuel causes the burning process to come to a complete
stop and requires the boiler to be fired up again.
In order to save fuel, the burner chamber as well as the convection channels must be kept clean.
The walls and water tubes in the furnace chamber are to be cleaned through the cleanout and
inspection doors.
ATTENTION!
Remember to close the feeder cover tightly.
ATTENTION!
Do not stand in front of the boiler when opening the boiler door as you may run
the risk of getting burn.

Tips when using the boiler
(USER)
the boiler can be operated by two adults who have familiried themselves with the manual
the presence of unsupervised children in the boiler room, or allowing them to operate the
boiler is forbidden.
ensure that the boiler is switched off during any works with flammable materials that emimt
flammable gases or fumes e.g glueing, painting etc.)
firing up on a layer of fuel, through the observation door, arrange crumpled pieces of paper
and lay small pieces of wood on them. Next, switch on the controller, light up the paper and
close the door. Do not use flammable liquids to fire up the boiler!
turn off the boiler before clearing out the exhaust carbon from the retort, gutter etc.( „STOP”
position)
turn off the boiler before stoking the b
oiler („STOP” position)
turn off the boiler before cleaning („STOP” position)
do not overheat the boiler
do not place any flammable material in the close vicinity of the boiler
during ash removal, any flammable materials should be kept at a distance of 150 cm from
the boiler
the ash should be placed in heat resistant containers with a lid
if the boiler operates at the temperature lower that 60C, the steel exchanger may „sweat”
and cause corrosion that shorten the boiler life span. That is why the minimum operation
temperature of the boiler should be 60C
