DAMPING
Routine damping of the stove is based on selection of the
Damp-
ing
function from controller menu. The controller will lock fuel feeding
and the stove will be damped after combustion of current dose of the
fuel in the burner. Power shutdown will also result in damping a stove
after fuel in the burner will be burnt.
If it is necessary to quickly damp a flame you should charge fur-
nace chamber with dry sand or ash after power supply shutdown. It is
not allowed to damp a flame by pouring it with water because it may
damage components of the equipment.
After a longer break in equipment’s operation you
should check flow capacity of the flue.
6.2.4.
POWER FAILURE DURING OPERATION
Fans and feeder will stop operation in case of power failure during
stove operation. Fuel dose in the burner should be burnt-out and flue
gas removed by a chimney draught. This will ensure safe shutdown of
the stove. Apply damping (chapter 6.2.3) is necessary (lack of suitable
draught).
6.2.5.
LACK OF WATER SUPPLY DURING OPERATION
If user of the stove notifies water deficiency in the heating system
then it is absolutely necessary to disconnect the stove from electric
supply. Stove can be restarted when the fault is removed from the heat-
ing system and the controller is operating normally and there is no error
message.
If there is considerable water loss from the heating system (or user
does not respond to such loss) then the operation of correctly working
stove will be stopped by the controller. Stop occurs after exceeding of
one of the limiting temperatures:
water temperature in boiler,
flue gases temperature.
The controller will switch to automatic damping and will not allow
further use of the stove and will display an error message. Recovery of
normal operation of the stove is possible after restart of the controller
by authorized service after the fault is removed.
In case of failure of the controller, sensors or other events, which
may cause that the stove is continuously heating the system, causing
water losses, the increasing temperature will activate the STB limiter,
which will disconnect supply from the stove and will prevent damage of
the stove and central heating system.

CLEANING AND MAINTENANCE
All operations related to cleaning of all components
should be carried out when the stove is completely
cold. It is required to use protective gloves.
It is a good practice to ensure good ventilation of the
room during cleaning of the fireplace.
7.1.1.
WATER SYSTEM
At least twice a year you should carry out inspection and mainte-
nance of all components ensuring safe operation of the water unit and
central heating system, including safety valve and thermal safety valve.
If longer break in operation of stove is planned and if it is possible that
temperature will fall below 0°C then you should discharge water from
the central heating system to prevent freezing of water in the system
and its damage. Check filling of the central heating system with water
prior to each start up after longer break in operation of the stove.
At least twice a year you should carry out inspec-
tion and maintenance of safety valve, thermal
safety valve and other components ensuring safe
operation of the water system and whole central
heating system.
Check level of water in the central heating system
after each longer break in operation of the DEFRO
HOME AQUAPELL stove.

BASIC OPERATIONS AND CLEANING BY THE USER.
Any service and maintenance works are to be carried out with me-
ticulous care and only by adults familiarized with this manual. The dry
stove should not be cleaned in the presence of children.

7.2.1.
CLEANING BEFORE EACH STARTING
Prior to every successive start-up of the equipment the ash con-
tainer should be cleaned and emptied, handling the ash with due care.
Remove ash-pan for this purpose and remove the remaining dust. Dust
can be removed using vacuum cleaner only if it is completely cold. Use
vacuum cleaner adapted to removing the particles of a specified size
for this purpose.
Remove the ash-pan to outside. Empty the ash-pan and remove
the dust from ash-pan recess. Rotate ash-pan cover’s handle by
90 degrees.
Deflect cover of ash-pan downwards
