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).

Local Building Regulations..

The Building Regulations (Part L).

The Buildings Standards (Scotland - Consolidated) Regulations. British Standards

Codes of Practice (BSI):

Model Water By-Laws

For Northern Ireland, observe the current applicable regulations.

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.

A

If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-

vided for removing the casing and for normal maintenance operations

3.3 Plumbing 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.

fig. 6 - Automatic bypass connection

The temperature drop between the delivery manifold and the return to the boiler should

not exceed 20°C.

B

Do not use the water system pipes to earth electrical appliances.

Before installation, carefully wash all the pipes of the heating system to remove any re-

siduals or impurities that could affect proper operation of the unit (as required by BS 7593

Building regs Doc L).

Carry out the connections to the unit as indicated in fig. 7.

fig. 7 - Water connections

Shutoff valve kit

Make sure to install the shutoff valves (supplied) between the boiler and the heating sys-

tem, allowing the boiler to be isolated from the system if necessary.

B

The safety valve outlet must be connected to a copper pipe of 15 mm diameter

with continuous fall from the boiler to run off the system water in case of over-

pressure in the heating circuit. Otherwise, if the discharge valve cuts in and

floods the room, the boiler manufacturer cannot be held liable. The drain must

be run to the outside of the building to avoid the risk of damage or injury due to

the hot water in case of overpressure in the system.

Make the boiler connection in such a way that its internal pipes are free of stress. If a

non-return valve is installed also on the DHW circuit (if provided for), it is necessary to

install a safety valve between the boiler and the circuit (with the non-return valve at least

3 m from the boiler) or an expansion tank for domestic use.

For installation, follow the instructions contained in the kit.
