2. USER’S SECTION
2.1. GENERAL WARNINGS FOR USER
2.1.1.
• Ensure that radiator/heating system, tap water and gas valves located
in your boiler are open, the heating system pressure is between 1 - 1,5
bar and system air is discharged,
• Gas is available in your gas line (you can control by igniting one of your
gas ovens),
• Make sure there are no combustible materials within the immediate
vicinity of the appliance or any corrosive chemicals that can damage
the appliance.
• If a room thermostat or control device is connected, ensure that it is at
ON position.
Our boiler has a built in frost protection (as long as the appliance is ON
and gas provided) for the system water contained within the boiler only, so
provisions need to be installed to protect the system pipe work in unheated
areas.
Turn OFF the boiler before any maintenance and repair action.
• Do not clean external frame of boiler while is functioning and do not use
easily flammable materials.
• Do not touch electricity cables.
• In case cables are damaged, the boiler and fuse switches and do not use
the boiler.
• Electrical cables of boiler and its accessories should be replaced by the
Authorised Service.
Safety:
In your own interest, and that of safety, it is the law that this boiler must
be installed by a Gas Safe Registered In IE, the installation must be carried
out by a Registered Gas Installer (RGII) and installed in accordance with the
current edition of I.S. 813 “Domestic Gas Installations”, the current Building
Regulations and reference should be made to the current ETCI rules for
electrical installation.
It is essential that the instructions in this booklet are strictly followed, for
safe and economical operation of the boiler.
Important Notes:
• This appliance must not be operated without the casing correctly fitted
and forming an adequate seal.
• If the boiler is installed in a compartment then the compartment MUST
NOT be used for storage purposes.
• If it is known or suspected that a fault exists on the boiler then it
MUST NOT BE USED until the fault has been corrected by a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII).
• Under NO circumstances should any of the sealed components on this
appliance be used incorrectly or tampered with.
• This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of

2.4. CUSTOMIZING BOILER FEATURES
As your boiler has an advanced electronic card, operation conditions and
certain parameters related with your preferences may be changed by
our Authorised Service. Please consult our authorised service when any
changes requested in below given parameters.
When boiler starts, there’s a ramp-up time for reaching requested power
from minimum power and this is set as 10 minutes as default. This value can
be set from 0 to 80 corresponding to 0 - 800 seconds.
The maximum Central Heating power can be adjusted by this parameter.
This parameter should be adjusted as 1 for ground heating or heating
systems operating with low temperature. 0 (zero) value is selected for
radiator systems to operate at high temperatures as standard.
This feature is disabled as default factory setting (0). Child Protection (key-
lock) is enabled when parameter is adjusted to 1. Keys are locked after 2
minutes following use when the feature is enabled. Key-lock is released
child protection
For other functions / parameters to customize your boiler, please refer to
the installation & service manual.
The boiler has to be switched to OFF mode first. It is possible to activate
deaeration function pressing RESET and ”-“ for circle time.
During this function pump and 3-way valve are activated/ deactivated in
order to have deaeration of the hydraulic plant.
This function ends pushing again RESET and ”-“ for circle time or at the end
of deaeration time: 12 minutes.

2.6. RECOMMENDATIONS FOR ECONOMICAL USE OF
Your is adjusted at ECO mode for economic use, we recommend not to
change it
Heat loss calculation of the boiler location should be made correctly
and boiler capacity should be selected accordingly. Devices not having
adequate capacity shall give late responses to heating requests, devices
with higher capacity may cause discomfort and more fuel consumption as
they turn ON and OFF more frequently. Therefore, boiler capacities should
be selected according to the place used.
Insulation of your building is the most important item reducing the heat
loss and gas consumption. However, as your has the highest thickness
insulation of its class, heat loss is minimized.
Ensure balancing the rest pump head of the appliance by making reduction
adjustments from radiator valves. Placing furnitures in front of radiators
prevents air circulation and causes discomfort and more fuel consumption.
Reducing radiator valves of rooms not used for a long period or if
thermostatic radiator valve is used, bringing to the lowest position then,
closing room doors will provide saving.
Always adjust the domestic hot water temperature as (38~42 °C) for
a considerable power saving. In addition, high domestic hot water
operation of the device (for instance, longer heating periods, less flow rate).
You can both acquire savings and comfort by balancing the heat distribution
among the house by using Thermostatic Radiator Valves.
Room Thermostats
Your boiler will operate more economically as you will have the chance
to adjust requested room temperature according to comfort via room
thermostats. Thus, you can adjust temperature of your room as you wish,
and also you can acquire approximately 6% power saving with every
degree of temperature decrease.
Do not leave windows slightly open for ventilating room/rooms. In
such case, continuous heat loss will occur and not having any certain
improvement in the room air.
Fully opening windows for a short period provides a better result. Bring
thermostatic radiator valves to lowest position when ventilating rooms.
to preserve the boiler’s integrity and keep the safety features,
performance and reliability, you must at least execute maintenance
operations on a yearly basis in compliance with national, regional, or local
standards in force.
We recommend a yearly cleaning and maintenance contract with an
authorised local firm.
