•

Use only original spare parts for all devices with optionals or kits (including electrical ones).

WARNING: this device must be used for its intended purpose, i.e., heating and production of domestic hot water. Any other use is improper and therefore dangerous. The constructor will have no contractual or extracontractual liability for damage caused by
incorrect installation and/or use or by non-observance of instructions supplied by the constructor.

This device must be used exclusively with a sealed central heating system equipped with an expansion vessel.

2) WARNINGS REGARDING INSTALLATION

Warranty expires 12 months from date of installation and in all cases no later than 18 months from date of construction. First start-up must be performed by authorised personnel only. For any operation on the hydraulic, gas, or electrical circuit regarding the
heating unit, refer to authorised technicians only and use original spare parts only. Wall-mounted boilers are not to be installed in damp rooms, and must be protected against sprays or jets of water or other liquids to prevent malfunctions of the electrical and
heating devices. They must not be exposed to direct steam from cookers, and nothing must be placed on top of them. This heating unit has been constructed to heat the home and to produce hot water. The constructor declines all responsibility for incorrect
installation and/or use of the device. Do not leave the device on when it is not being used: close the gas cock and turn off the mains switch. If you smell gas in the room in which the device is installed, do not operate any electrical switches, telephones, or any
other device that might cause a spark. Immediately open doors and windows to create an air current to clear the room. Close the main gas cock (at the meter) or the cylinder cock, and request immediate technical service.
Do not tamper with the device.

SYSTEMS WITH THERMOSTATS

A by-pass must be installed in heating systems with radiators thermostats.
As required by current norms, these devices must be installed by qualified personnel only, who must respect norms UNI-CIG 7129 and 7131 and revisions, fire department regulations, and requirements of the local gas company. Before installing the boiler,
make sure that the water and heating systems are compatible with its output. The room must be properly ventilated by means of an air intake (see UNI 7129/92 and UNI 7129/95 FA).
The air intake must be at floor level open flue only, at a point where it cannot be obstructed, and protected by a grate that does not reduce the useful section of flow.
The use of air flows from adjacent rooms is permitted as long as such rooms are in depression with respect to the outside and as long as there are no wood-burning fireplaces or fans installed there. If the boiler is to be installed externally (for example, on
balconies or terraces), make sure that it is protected against atmospheric agents to prevent damage to components and voiding of the warranty. In such cases we recommend building a heat compartment to protect the boiler against inclement weather.
Check the technical data on the packing and on the plate located inside the front casing. Check that the burner is suitable for use with the type of gas available.
Make sure that all pipes and connections are perfectly sealed and that there are no gas leaks.
All pipework should be chemically flushed to remove any residues that might negative effect the operation of the boiler.

GENERAL INSTALLATION REQUIREMENTS

GAS SAFETY

It is the law that all gas appliances are installed by a CORGI registered installer (you can check this by contacting corgi on 01256.372200) in
accordance with the regulations listed below. Failure to install appliances correctly could lead to prosecution. It is in your own interest and
that of safety to ensure that the law is complied with. Failure to have your appliance installed to comply with the installation instructions and
the requirements listed below could invalidate your guarantee.

RELATED DOCUMENTS

The installation of the boiler must be in accordance with the relevant requirements of the Gas Safety regulations, Building regulations, I.E.E.
regulations and the bylaws of the local water authority.
It should be in accordance also with any relevant requirements of the local authority and the relevant recommendations of the following
British Standard Codes of Practice:

B.S 6400: 1985 & B.S. 6891 : 1988.
BS 5376: Selection and Installation of Gas Space Heating ( 1 and 2 family gases)
Part 2: Boilers of rated input not exceeding 60 Kw
BS 5449: Central Heating for domestic premises
Part 1: Forced circulation Hot Water System
CP 342: Centralised Hot Water Supply BS 6700 : 1987
Part 2: Buildings other than individual
BS 5440: Flues and air supply for Gas Appliances of rated input not exceeding
60 Kw (1 and 2 family gases)
Part 1: Flues
Part 2: Air Supply
BS 5446: 1990: Installation of Gas Hot Water supplies for domestic purposes

GAS SUPPLY

Service Pipes: The local gas region should be consulted at the installation planning stage in order to establish the availability of supply of
gas. An existing service pipe must not be used without prior consultation with the local gas region.
Meters: A gas meter is connected to the service pipe by the local gas region or local gas region contractor. An existing meter should be
checked to ensure that it is capable of passing an additional 3.4 m3/hr (125 ft/hr) before the appliance is installed. The meter outlet
governor should ensure a nominal dynamic pressure of 20m Bar, (8 in wg) at the boiler. Installation pipes should be fitted in accordance with
BS6891.1988.

Pipework that supplies the boiler must be a 22 mm. ininterrupted supply from meter to the isolation cock of the

boiler.

The complete installation must be tested for soundness as described in the above code, BS 6400: 1985 & BS6891.

IMPORTANT: BOTH THE USER AND THE MANUFACTURER RELY UPON THE INSTALLER, WHOSE JOB IS TO INSTALL THE BOILER
AND CONNECT IT TO A CORRECTLY DESIGNED HEATING SYSTEM. THE INSTALLER SHOULD ACQUAINT HIMSELF WITH THE
CONTENTS OF THIS PUBLICATION AND THE RELEVANT BRITISH STANDARDS CONCERNING INSTALLATION REQUIREMENTS.

LOCATION OF BOILER

In siting the combination boiler, the following limitations MUST be observed:
The position selected for installation should be within the building, and MUST allow
adequate space for installation, servicing and operation of the combination boiler, and for air circulation around it. The boiler is not suitable
for external installation.
This position MUST also allow for a suitable flue termination to be made. The boiler must be installed on a flat vertical wall which is capable
of supporting the weight of the combination boiler, and any ancillary equipment.
If the boiler is to be fitted in a timber framed building it should be fitted in accordance with the British Gas publication "Guide for Gas
Installations in Timber Frame Housing, Reference IGE/UP/6. If in doubt, advice must be sought from the local region of British Gas.
The boiler may be installed in any room or internal space, although particular attention is drawn to the requirements of the current I.E.E.
Wiring Regulations, and in Scotland the electrical provisions of the Building Regulations applicable in Scotland, with respect to the
installation of the boiler in a room or internal space containing a bath or shower.
Where a room-sealed appliance is installed in a room containing a bath or shower, any electrical switch or appliance control utilising mains
electricity must be so situated that it cannot be touched by a person using the bath or shower.
A compartment used to enclose the combination boiler MUST be designed and constructed specifically for this purpose. An existing
cupboard, or compartment, may be used provided it is modified accordingly.
Where installation will be in an unusual location, special procedures may be necessary. BS 6798 gives detailed guidance on this aspect.
For clearances to be made available for installation and servicing, see Sections 5.2.2. to 5.2.4.

FLUE POSITION

IMPORTANT: THE FLUE SYSTEM SHALL BE INSTALLED IN ACCORDANCE WITH THE RECOMMENDATIONS CONTAINED IN BS
5440:1.
The boiler MUST be installed so that the terminal is exposed to the external air.
It is important that the position of the terminal allows free passage of air across it at all times.
If the terminal discharges into a pathway or passageway check that combustion products will not cause nuisance and that the terminal will
not obstruct the passageway.
In certain weather conditions a terminal may emit a plume of steam. Positions where this would cause a nuisance should be avoided.
IMPORTANT REQUIREMENT: The correct dimensional relationship between the terminal and any obstruction, openable window or
ventilator as shown in Fig 1 pag.7 It is ESSENTIAL TO ENSURE, in practice, that products of combustion discharging from the terminal
cannot re-enter the building, or any other adjacent building, through ventilators, windows, doors, other sources of natural air infiltration, or
forced ventilation/air conditioning systems. If this should occur, the appliance MUST BE TURNED OFF IMMEDIATELY and the local gas
region consulted.
Where the lowest part of the terminal is fitted less than 2m (6.6ft) above a balcony, above ground, or above a flat roof to which people have
access, the terminal MUST be protected by a purpose designed guard.
Where the terminal is fitted within 850mm (34in) of a plastic or painted gutter, or 450mm (18in) of painted eaves, an aluminium shield of at
least 1000 mm (40in) long should be fitted to the underside of the gutter painted surface.
The air inlet/products outlet duct and the terminal of the boiler MUST NOT be closer than 25mm (1in) to combustible material.
