scraper tool.
Caution! Ashes may contain smoldering charcoal.
* Dispose of ashes only in specially designated
facilities. Disposing of ashes into public garbage
containers may cause fire.
9.2.1. Preparing for the new heating season. Recommended
boiler maintenance procedures:
1. Remove internal safety gates inside the boiler firebox
(combustion chamber). Scrape thoroughly the firebox
using the scraper brush from the boiler cleaning kit.
Remove tar and soot deposits as they obstruct normal
heat radiation.
2. Clean thoroughly water jacket ribs. Remove cinder and
soot deposits using the scraper tool and brush from
cleaning kit.
3. Remove inspection opening lid below the boiler flue
opening and remove ash deposits in there.
*
Caution! Replace inspection opening lid gasket wth
a new item if its integrity is broken.
4. Clean well metal grill in the bottom part of the boiler.
Check whether gaps between flue pipes are well cleaned.
Tar deposits or residues of non-combustive materials
inside the boiler firebox deteriorate normal combustion
process.
Caution! If necessary, adjustment of boiler doors
*
or replacing insulation rope, please contact in your
installer.
5. Clean air distribution pipes located below boiler flue
pipes. Ash deposits inside them obstruct the inflow
of air into the firebox (combustion chamber). In case
dismantling of air distribution pipes is needed use
wrench S13. Once the ash is swept out mount them back
in place.
6. Clean fan turbine. Use a vacuum cleaner unit to remove
dust from inside the fan turbine.
9.3. Important recommendations for long-lasting and
correct operation of the boiler.
- Carry out periodic maintenance of boiler following the
prescriptions in Section 9.2.
- The allowed moisture content of the fuel used must not
exceed 15% ÷ 20%.
- Gas emission in the combustion chamber may result in
the formation of tar and condensate (acids). Therefore, a
mixing valve must be installed and it must be adjusted so
that the minimum temperature of the water returning in
the boiler is 65° С. This extends the life span of the boiler
and its warranty. The operating temperature of the water
in the boiler must be within the 65 ÷ 80°С range.
- It is not recommended to operate the boiler for a long
period of time at an output lower than 50%.
- When using circulation pump, boiler operation must be
controlled via a separate thermostat in order to ensure the
prescribed rated temperature of the return water.
- The eco-friendly operation of the boiler is realized at rated
output.
- It is recommended to install a storage/buffer tank and
pump type group with thermostatic mixing valve to the
boiler. The capacity of the storage tank is 55 L of water per
1 kW installed boiler power.
- Maintenance and operation training for the boiler is
conducted by an authorized installer.
Failure to observe the installation and operating
*
requirements described in the manual and the
service booklet voids the warranty.

10. CONTROLLER

The controller is designed for controlling CH boilers. It is
regulating the pump responsible for CH water circulation,
HCW pump and the fan.

Explanation of buttons:
p - Navigation arrow UP / PLUS
q - Navigation arrow DOWN / MINUS
MENU button - Enter menu / approve settings
EXIT button - canceling settings
- Power switch ON/OFF
- Fan
- CH PUMP- central heating
- WUW PUMP - domestic hot water (DHW)
- Manual operation
10.1.1. Fire up – The cycle begins when you activate the fire
up function in the controller's menu and is active until the
central heating boiler temperature reaches 40°C (the default
fire-up threshold), on condition that the temperature does
not drop below this value for 2 min. (the default fire-up
time). If these conditions are met, the controller will switch
to the operation mode and the manual operation symbol on
the housing will be deactivated. If the controller fails to reach
parameters required for entering into the operation mode
within 30 min. from activation of the fire-up function, the
„Unable to fire up" message will appear on the display. In
such a case, the fire-up cycle needs to be restarted.
10.1.2. Operation – The operation cycle is the basic
functionality of the controller. The power of fan is regulated
by the user. If the temperature rises above the set
