Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature required in the rooms. If the room ther-
mostat is not installed, the boiler will keep the system at the set system delivery setpoint
temperature.
Room temperature adjustment (with optional remote timer control)
Using the remote timer control, set the required temperature in the rooms. The boiler will
adjust the system water according to the required room temperature. For operation with
remote timer control, please refer to the relevant instruction manual.
ECO/COMFORT selection
The unit has a function that ensures a high domestic hot water delivery speed and max-
imum comfort for the user. When the device is activated (COMFORT mode), the water
contained in the boiler is kept hot, thereby ensuring immediate availability of hot water
on opening the tap, without waiting times.
The user can deactivate the device (ECO mode) by pressing the eco/comfort button
(detail 7 - fig. 1). In ECO mode the display activates the ECO symbol (detail 12 - fig. 1).
To activate the COMFORT mode, press the eco/comfort button (detail 7 - fig. 1) again.
Adjustments from Remote Timer Control

3.1 General Instructions
B
This unit must only be used for its intended purpose. This unit is designed to
heat water to a temperature below boiling point and must be connected to a
heating system and/or a water supply system for domestic use, compatible with
its performance, characteristics and heating capacity. Any other use is deemed
improper.
THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN COMPLI-
ANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE
PROVISIONS OF CURRENT LAW, THE REQUIREMENTS OF THE TECHNICAL
STANDARDS (BS) AND ANY LOCAL REGULATIONS AND THE RULES OF PROPER
WORKMANSHIP.
Incorrect installation can cause damage or injury for which the manufacturer cannot be
deemed responsible.
The unit must be installed in compliance with these instructions and the following
standards applicable in Great Britain.
Gas Safety Regulations (Installations & Use).
Local Building Regulations.
The Building Regulations (Part L).
The Buildings Standards (Scotland - Consolidated) Regulations).British Standards
Codes of Practice (BSI):
Model Water By-Laws (Great Britain)
For Northern Ireland the relevant laws in force must be observed.
Safe handling of materials
Pay attention when handling the boiler insulation panels as they contain materials that
could irritate the skin. No part of the boiler contains asbestos, mercury or CFC's.
The use Personal Protective Equipment (PPE) is always recommended.
Advice for transport and handling
For lifting and transporting always take suitable safety precautions: keep your back
straight, bend knees, do not turn your body, move feet, avoid bending forward or side-
ways and keep the load as close as possible to your body.
If possible, use a trolley or other suitable means to carry the boiler.
Grip the boiler firmly and, before lifting it, try and find the point where the load is concen-
trated in order to establish the centre of gravity and suitably reposition yourself. Ideally
seek assistance in lifting the boiler.
3.2 Place of installation
B
The combustion circuit is sealed with respect to the place of installation and
therefore the unit can be installed in any room. However, the place of installa-
tion must be sufficiently ventilated to prevent the creation of dangerous condi-
tions in case of even slight gas leaks. This safety regulation is provided for by
EEC Directive no. 2009/142 for all gas units, including those with a sealed
chamber.
In any case, the place of installation must be free of dust, flammable materials or objects or
corrosive gases.
The boiler is arranged for wall mounting and comes standard with a hanging bracket. A
paper template for marking the drilling points on the wall is provided in the box. The wall
fixing must ensure stable and effective support for the boiler.
A
If the unit is enclosed in a cabinet or mounted alongside, a space must be provided for remov-
ing the casing and for normal maintenance operations. The minimum measurements to be
respected are given in fig. 6.
