ECONCEPT TECH 18 A

4.2 Startup
Before lighting the boiler

•

Check the seal of the gas system.

•

Check correct prefilling of the expansion tank.

•

Fill the water system and make sure all air contained in the boiler and the system
has been vented.

•

Make sure there are no water leaks in the system, DHW circuits, connections or boiler.

•

Check correct connection of the electrical system and efficiency of the earthing system.

•

Make sure the gas pressure for heating is that required.

•

Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler

Checks during operation

•

Switch the unit on.

•

Check the tightness of the fuel circuit and water systems.

•

Check the efficiency of the flue and air/fume ducts while the boiler is working.

•

Check the correct tightness and efficiency of the condensate removal system and trap.

•

Make sure the water is circulating properly between the boiler and systems.

•

Make sure the gas valve modulates correctly in heating and domestic hot water pro-
duction.

•

Check proper lighting of the boiler by turning it on and off several times with the room
thermostat or remote control.

•

Make sure the fuel consumption indicated on the meter matches that given in the
technical data table on cap. 5.

•

Make sure that with no heating demand the burner correctly lights on opening a hot
water tap. Check that the heating circulating pump stops on opening a hot water tap
during heating operation and there is a regular production of hot water.

•

Check correct programming of the parameters and carry out any required customi-
sation (compensation curve, power, temperatures, etc.).

4.3 Maintenance
Periodical check

To ensure proper operation of the unit over time, have qualified personnel carry out a
yearly inspection, providing for the following checks:
•

The control and safety devices (gas valve, flow meter, thermostats, etc.) must func-
tion correctly

•

The fume exhaust circuit must be perfectly efficient

•

The sealed chamber must be tight

•

The air-fume end piece and ducts must be free of obstructions and leaks

•

The burner and exchanger must be clean and free of deposits For possible cleaning
do not use chemical products or wire brushes

•

The electrode must be properly positioned and free of scale

•

The gas and water systems must be tight.

•

The water pressure in the cold water system must be about 1 bar; otherwise, bring
it to that value

•

The circulating pump must not be blocked.

•

The expansion tank must be filled.

•

The gas flow and pressure must correspond to that given in the respective tables

•

The condensate evacuation system must be efficient with no leakage or obstruc-
tions

•

The trap must be full of water.

4.4 Troubleshooting
Diagnostics

In case of operation faults or problems, the display flashes and the fault identification
code appears.
There are faults that cause permanent shutdown (marked with the letter “

”): to restore

operation just press the

reset

button (detail 6 - fig. 1) for 1 second or RESET on the op-

tional remote timer control if installed; if the boiler fails to start, it is necessary to firstly
eliminate the fault.
Faults marked with the letter “

” cause temporary shutdowns that are automatically reset

as soon as the value returns within the boiler's normal working range.

Table of faults

Table. 8 - List of faults

Fault code Fault

Possible cause

Cure

A01

No burner ignition

No gas

Check the regular gas flow to the
boiler and that the air has been
eliminated from the pipes

Ignition/detection electrode fault

Check the wiring of the electrode and
that it is correctly positioned and free
of any deposits

Faulty gas valve

Check the gas valve and replace
it if necessary

Check the gas supply pressure

Trap blocked

Check the trap and clean it if
necessary

stage
(6 times in 4 minutes)

Ionisation electrode fault

Check the position of the ionisation
electrode and replace it if necessary
