Introduction

The XIGNAL CEXIGNAL CE

XIGNAL CEXIGNAL CE

XIGNAL CE boiler is a high efficiency heat generating appliance of a totally new design. It is

environment friendly, gas fired and prduces hot water for both the central heating system and domestic

hot water.

The new concept of XIGNAL CEXIGNAL CE

XIGNAL CEXIGNAL CE

XIGNAL CE is that it is fitted with a microcomputer to regulate the boiler performance

through technically sophisticated controls. This guarantees correct and optimum operation while being

extremely simple to use. The diagnostic information and the operative status of the boiler are constantly

visible on the display and can also be communicated by synthesized voice.

The boiler operation can be easily programmed be setting four daily heating levels. The fuel management

system incorporates an internal and external sensor accurately calculating the heat output required (the

temperature of the water in the radiators is regulated depending on the external temperature).

XIGNAL CEXIGNAL CE

XIGNAL CE has a new generation gas burner ensuring perfect combustion with high flame efficiency and

low emissions of pulluting gases like NOx and CO2. The burner is ignited and monitored electronically

ensuring the burner performance functions completely automatic and safe. This system also isolates the

boiler from the domestic environment, ensuring total safety.

XIGNAL CEXIGNAL CE

XIGNAL CE heat exchanger is made entirely of copper this ensures high efficiency even when the heating

is low, protection against rust and oxidation makes the heat exchanger both reliable and long lasting.

GENERALDESCRIPTIONGENERALDESCRIPTION

GENERALDESCRIPTION

The boiler is able to operate with two types of fuel gas: natural or propane (L.P.G.). The type of gas should

be chosen when the boiler is ordered. Conversions can also be carried out during the installation phase

.Theboileriscontrolled by an internal microcomputer and allsettingsto the regulating systems are carried

out on the assembly line by use of software. This ensures that the set values always remain absolutely

accurate throughout plant use

The user may program and select the various options through the control panel. These functions include

summer/winter operation, choice of the sanitary water temperature and that of the plant delivery, daily

program setting and activation, boiler release.

The heating function is only activated when Winter operation is selected (key ). The microcomputer

handles the heating function either according to the set daily program or according to the temperature

set on the knob of the ambient unit. In both cases, the demand for heat will activate the circulation pump,

the fan and the electronic equipment to start the burner. The burner ignites at a power value that will have

been preset according to the fuelling gas. If the pressure in the heating system is less than 0.5 bar or more

than 2.5 bar, the microcomputer will prevent boiler operation for safety reasons.

During operation, the plant delivery temperature is regulated according to the external temperature

(detected by the relative probe). Temperature regulation will be proportional to the compensating curve

set on installation according to the structural characteristics of both the building and system.

When the temperature of the water in the boiler approaches the value established by the computer, the

valve will reduce the amount of gas (modulating) delivered to the main burner in order to keep the water

temperature near to the required value. If the water temperature reaches the preset value, the burner will

go out and will wait 2 minutes until igniting again. Having terminated the demand for heat, the burner

will stop while the circulator will continue to operate for six minutes so that the temperature is evenly

distributed throughout the system.

If hot water is used during the heating system, the microcomputer will detect this by means of the flowmeter

and will disactivate the heating function. This stops the circulator and activates hot water production. Hot

water is constantly maintained at the set value even during different water flow rates. This is due to a

correct establishment of the outlet flow of hot water and adequate modulation of the burner rating. Once

use of hot water ceases, the computer will wait for 2 minutes before re-activating the heating function.

Only hot water production is activated during "Summer" operation. However, the circulating pump of

the heating function will operate for 1 sec. at the end of each demand for water in order to prevent the

pump itself from sticking.

The microcomputer continuously checks that boiler operation is correct. In the event of faults, these are

immediately visualized (the display will flash) and notified by synthesized voice when the relative button

is depressed. Boiler operation will be inhibited until the fault is rectified or, in some cases, until the boiler

is manually reset.

All faults are memorized by the microcomputer together with the other operational parameters. This

enables the technical assistance service to proceed with a correct diagnosis.

Installation Details

Gas Safety (Installation & Use) Regulations: 1984

In the interest of safety, it is the law that all gas appliances are installed by a competent person in accordance with

the above Regulations, Building Regulations/Building Standards Scotland, Codes of Practice, current I.E.E.

Regulations and the byelaws of the Local Water Undertaking. Failure to comply with the Regulations may lead

to prosecution; it is in your interest and that of safety to ensure that the law is complied with.

Important -Important -

Important - 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 Installation in Timber Frame Housing: Reference DM2. If in doubt

advice must be sought from the Local Gas Region of British Gas Plc.

Location of Boiler

The installation of the XIGNAL CEXIGNAL CE

XIGNAL CEXIGNAL CE

XIGNAL CE must be on a suitable non-combustible load bearing wall which will provide

an adequate fixing for the boiler mounting bracket assembly. The location should be in an area where the water

pipes will not be subjected to frost conditions. In siting the combination boiler the following limitations mustmust

mustmust

must be

observed:

The combination boiler may be installed in any room or internal space, although particular attention is

drawn to the requirements of the current, i.e. wiring regulations and in Scotland the electrical provisions of the

building regulations applicable in Scotland, with respect to the installation of the combination 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, should be so situated that it cannot be touched by a person using the

bath or shower.

A Quinnel Barrat and Quinnel guard (part. No. C2) should be screwed to the wall centrally over the terminal, when

the distance is less than 2 m from the outside floor.

Air Supply

The room in which the boiler is installed does not require a purpose provided vent. If the boiler is installed in a

cupboard or compartment, permanent air vent are required in the cupboard or compartment, one at high level

one at low level, either direct to the outside air to a room. Both high and low level air vents must communicate with

the same space.

Minimum effective area requirements of compartment air vents (for cooling purposes only) (fig. 4).
