Adjustments from Remote Timer Control
If the Remote Timer Control (optional) is connected to the boiler, the above ad-
A
justments are managed according to that given in table 1.
Table. 1
Heating temperature setting Adjustment can be made from the Remote Timer Control menu and the
boiler control panel.
Hot water temperature adjustment Adjustment can be made from the Remote Timer Control menu and the
boiler control panel.
Summer/Winter Switchover Summer mode has priority over a possible Remote Timer Control heat-
ing demand.
Eco/Comfort selection Adjustment can only be made from the boiler control panel.
Water system pressure regulation
The filling pressure read on the boiler water gauge with the system cold must be approx
1.0 bar. If the system pressure falls to values below minimum, the boiler stops and fault
F37 is displayed.
3. INSTALLATION
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 its heating capacity. Any other use is
deemed improper.
BOILER INSTALLATION MUST ONLY BE CARRIED OUT BY QUALIFIED PERSON-
NEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL
MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF THE
TECHNICAL STANDARDS (BS), ANY LOCAL REGULATIONS AND THE RULES OF
PROPER WORKMANSHIP.
Incorrect installation can cause damage or injury for which the manufacturer declines
any responsibility.
Installation of this unit must be carried out in strict compliance with the present
instructions and the following regulations applicable in Great Britain.
Gas Safety Regulations (Installations & Use).

Safe handling of materials
Pay attention when handling the boiler insulation panels because the material they are
made of could irritate the skin. No part of the boiler contains asbestos, mercury or CFC's.
Advice for transport and handling
For lifting and transport always take suitable safety precautions: keep your back straight,
bend knees, do not turn your body, move feet, avoid bending forward or sideways 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.

3.2 Place of installation
The combustion circuit is sealed with respect to the place of installation room, therefore
the unit can be installed in any room. However, the place of installation must be ade-
quately ventilated to prevent the creation of dangerous conditions in case of even small
gas leaks. This safety regulation is laid down by EEC Directive no. 90/396 for all gas
units, including those with sealed chamber.
The unit is suitable for operation in a partially protected place in conformity with EN 297/
A6, with minimum temperature -5°C. If equipped with the special antifreeze kit, it can be
used with minimum temperatures to -15°C. The boiler must be installed is a protected
place, e.g. under the slope of a roof, inside a balcony or in a sheltered recess.
The place of installation must in any case be free of dust, flammable materials or objects
or corrosive gases.
The boiler is arranged for wall mounting and comes standard with a hooking bracket. The
wall fixing must ensure a stable and effective support for the generator.
If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
A
vided for removing the casing and for normal maintenance operations
3.3 Water connections
Important
The heating capacity of the unit must be previously established by calculating the build-
ing's heat requirement according to the current regulations. To ensure proper operation
and long boiler life, the plumbing system must be adequately sized and complete with all
the necessary accessories, including a room thermostat, a thermostattable valve (TRV)
etc. The system delivery and return pipes must have a diameter of at least 22 mm for the
first 3 m of length from the unit.
If the system delivery and return pipes follow a path where air pockets can form in certain
places, it is advisable to install vent valves at these points. Also, type "A" drain cocks
must be installed at the lowest points in the system to allow complete emptying.
B
An automatic bypass with flow rate of at least 6 l/min. must be installed (con-
nected as far away as possible from the boiler) if radiators with thermostatic
valves have been connected.

The temperature drop between the delivery manifold and the return to the boiler should
not exceed 20°C.
