GENERAL

The complete installation MUST be tested for gas soundness and purged as described in the above code.

FLUE INSTALLATION

The flue must be installed in accordance with the recommendations of BS. 5440-1:2000. In IE refer to I.S. 813:2002.

The following notes are intended for general guidance:

1. The cross-sectional area of the flue, serving the boiler, MUST NOT be less than the area of the flue outlet of the boiler.

If flue pipe is to be used it MUST NOT be less than the diameter of the flue outlet connection on the boiler.

2. Flue pipes and fittings should be constructed from one of the following materials:

a. Aluminium or stainless steel.

b. Cast iron, coated on the inside with acid resistant vitreous

enamel.

c. Other approved material.

3. If twin walled flue pipe is used it should be of a type

acceptable to British Gas.

4. If a chimney is to be used it should preferably be one that is composed of, or lined with, a non-porous acid resistant material.

Notes.

Chimneys lined with salt -glazed earthenware pipes are acceptable if the pipes comply with BS.65 and BS.5440:1.

A flue pipe constructed from one of the materials listed in 2 a-c should form the initial connection to the lined chimneys.

Where a chimney is to be used that is not composed of, or lined with, a non-porous, acid resistant material it should be lined with a stainless steel flexible flue liner which complies with BS.715.

5. Before connecting the boiler to, or inserting a liner into, a flue that has been previously used then the flue MUST be thoroughly swept clean of any soot or loose material. If a register plate, restrictor plate or damper etc., is fitted in the flue then it MUST be removed before connecting the boiler to, or inserting a liner into, the flue.

6. The flue should terminate in accordance with the relevant recommendations given in BS.5440-1:2000. In IE refer to I.S.813:2002.

7. The flue MUST be fitted with a terminal (or ridge tile up to 5" flue diameter). The terminal shall be of a type which has been tested and found satisfactory by British Gas. This terminal must NOT be installed within 600mm (24") of an opening window, air vent or any other ventilation opening.

8. The chimney / flue lining MUST be sealed at both the top and the bottom.

IMPORTANT. It is absolutely ESSENTIAL to ensure, in practice, that the flue discharge is in a downdraught- free zone and that products of combustion discharging from the terminal cannot reenter the building or any other adjacent building through ventilators, windows, doors, other sources of natural air infiltration or forced ventilation / air conditioning systems.

The TTB is an automatic device which will reset once the wind conditions have returned to normal, subject to a built-in reset delay in excess of 10 minutes

The TTB is an important safety device and must not be put out of action or interfered with in any way.

This device is not a substitute for an independently mounted carbon monoxide detector.

In cases of repeated or continuous shutdown a competent person should be called to investigate and rectify the condition causing this and carry out an operational test after each intervention on the device. Only the manufacturer's original parts should be used for replacement.

AIR SUPPLY

Detailed recommendations for air supply are given in BS.5440:2. In IE refer to I.S. 813:2002. The following notes are for general guidance:

1. The room or internal space in which the boiler is installed MUST have, or be provided with, a permanent air vent. This vent MUST be either direct to outside air or to an adjacent room or internal space which must itself have, or be provided with, a permanent air vent at least the same size direct to outside air.

The minimum effective area of the permanent air vent(s) are specified in Table 3 and are related to maximum rated heat input of the boiler.

Table 3

Boiler size CF495 CF4120 CF4140

Effective 146 189 211 area

(in2) (23) (30) (32)

The air vent(s) must NOT have provision for closing or adjustment and should be sited to avoid risk of accidental damage or blockage.

If other methods of ventilation are envisaged, British Gas should be consulted before proceeding.

2. If the boiler is to be installed in a cupboard or compartment, permanent air vents are required (for combustion, flue dilution and cooling purposes) in the cupboard / compartment, at both high and low levels to ensure safe and efficient combustion and ventilation.

The air vents may either communicate with room/internal space (appropriately ventilated) or be direct to outside air. The minimum effective areas of the permanent air vents, required in the cupboard / compartment, are specified in Table 4 and are related to maximum rated heat input of the boiler.

Notes.

a. Both air vents MUST communicate with the same room or

internal space or MUST be on the same wall to outside air.

b. In siting the air vents care must be taken to avoid the

freezing of pipework.

c. Where cupboard / compartment air vents are open to a room

or internal space, the room or internal space MUST itself be provided with a permanent air vent, as previously specified.

d. The cupboard / compartment air vents must NOT

communicate with a bedroom, bed-sitting room or a room containing a bath or shower.

EFFECT OF AN EXTRACTOR FAN

If there is any type of extractor fan fitted in the premises there is a possibility that, if an adequate air inlet area from outside is not provided, spillage of the boiler flue products could occur when the fan is in operation. Where such installations occur a spillage test, as detailed in BS.5440-1:2000, MUST be carried out and any necessary action taken.

VENTILATION IN SERIES

In installations requiring 2 ventilators to be fitted in series, e.g. across a cavity wall, EACH ventilator should be sized in accordance with the above data. Where there are more than 2 ventilators in series, EACH should have an area of 50% in excess of the value quoted above.

WATER CIRCULATION SYSTEM

The boiler is suitable for connection to pumped open vent central heating systems, pumped central heating combined with pumped or gravity indirect domestic hot water supply systems and gravity or pumped indirect domestic hot water supply systems.

The boiler is NOT suitable for gravity heating systems.

The hydraulic resistance of the boiler at maximum output with

C (20

11 graph:

Water Flow Rate and Pressure Loss

F) temperature differentials are shown in the following

The central heating system should be in accordance with BS. 6798 and, in addition, for smallbore and microbore systems, BS. 5449:1.

The domestic hot water system, if applicable, should be in accordance with the relevant recommendations of BS. 5546.

Copper tubing to BS. 2871:1 is recommended for water carrying pipework.

The hot water storage cylinder MUST be of the indirect type and should preferably be manufactured of copper.

Single feed, indirect cylinders are not recommended.

The hot water cylinder and ancillary pipework not forming part of the useful heating surface should be lagged to prevent heat loss and any possible freezing - particularly where pipes run through roof spaces and ventilated underfloor spaces.

IMPORTANT

A minimum length of 2 metres of copper pipe MUST be fitted to both flow and return connections from the boiler before connection to any plastic piping.

The boiler must be vented. If venting cannot be done via a flow connection a separate vent MUST be fitted by the installer.

Draining taps MUST be located in accessible positions, which permit the draining of the whole system, including the boiler and hot water storage vessel. They should be at least nominal size and be in accordance with BS. 2879.

If required, a drain tap (not supplied) may be fitted to an unused bottom (1" BSP) tapping on the front of the boiler.

1/2" BSP

BOILER CONTROL INTERLOCKS

Caradon Ideal Limited recommend that heating systems utilising

full thermostatic radiator valve control of temperature in individual rooms should also be fitted with a room thermostat controlling the temperature in a space served by radiators not fitted with such a valve as stated in BS. 5449.

Central heating systems controls should be installed to ensure the boiler is switched off when there is no demand for heating or hot water.

When thermostatic radiator valves are used, the space heating temperature control over a living / dining area or hallway having a heating requirement of at least 10% of the boiler heat output should be achieved using a room thermostat, whilst other rooms are individually controlled by thermostatic radiator valves. However, if the system employs thermostatic radiator valves on all radiators, or two port valves without end switches, then a bypass circuit must be fitted with an automatic bypass valve to ensure a flow of water should all valves be in the closed position.

Dotted lines indicate flow rates equivalent to a

temperature rise of 11oC (20oF)

Mexico Super CF495 - CF4140 - Installation & Servicing

ELECTRICAL SUPPLY

WARNING. The appliance MUST be efficiently earthed.

Wiring external to the appliance MUST be in accordance with the current I.E.E. (BS 7671) Wiring Regulations and any local regulations which apply. For Ireland reference should be made to the current ETCI rules for electrical installations.

The boiler is supplied for 230 V ~ 50 Hz single phase.

Fuse rating is 3A.

Connection must be made in a way that allows complete isolation of the electrical supply such as a double pole switch having 3mm (1/8") contact separation in both poles, or a plug and socket, serving only the boiler and system controls. The means of isolation must accessible to the user after installation.

4 GRAVITY HOT WATER & PUMPED CENTRAL HEATING

1. Separate flow and return connections are used for each

service. All possible configurations are given in Frame 11 and ONLY those shown should be used.

2. The schematic pipework graph is based on the assumption that NO MORE than 8 elbows are used in the gravity loop, including entry to the boiler.

3. For each extra elbow in excess of 8 (R) MUST be reduced by 300 mm (12") or (H) increased by 100mm (4")

4. Whatever value is selected for (R), the value of (H) MUST be at least that indicated by the graph.

(R) = the horizontal distance between the

centre line of the cylinder and the boiler tappings used - measured along the pipe run.

(H) = the vertical distance between the top of the boiler

and the base of the cylinder.

Notes.

a. Flow and return pipes should rise vertically on

leaving the boiler.

b. Horizontal pipes should be ABOVE ceiling level

and as short as possible.

c. A MINIMUM inclination of 25 mm per 3 m run (1"

per 10') is required to avoid air locks.

a. A diaphragm type expansion vessel must be connected

at a point close to the inlet side of the pump, the connecting pipe being not less than 15mm (

1/2" nominal) size and

not incorporating valves of any sort.

b. The vessel capacity must be adequate to accept the

expansion of the system water when heated to 110 (230oF)

c. The charge pressure must not be less than the static

water head above the vessel The pressure attained in the system when heated to 110 least 0.35 bar (5lb/in

) less than the lift pressure of the

C (230oF) should be at

safety valve.

For guidance on vessel sizing refer to Table 5, Frame 6. For further details refer to BS.5449 and the British Gas Corporation publication : Material and Installation Specifications for Domestic Central Heating & Hot Water.

5. Cylinder

The cylinder must be either of the indirect coil type or a direct cylinder fitted with an immersion calorifier which is suitable for operating on a gauge pressure of 0.35 bar (5lb./in excess of the safety valve setting. Single feed indirect

cylinders are not suitable for sealed systems.

6. Make-up Water

Provision must be made for replacing water loss from the system, either:

a. From a manually fitted make-up vessel with a readily visible

water level. The vessel should be mounted at least 150mm (6") above the highest point of the system and be connected through a non-return valve to the system, fitted at least 300mm (12") below the make-up vessel on the return side of the domestic hot water cylinder or radiators.

b. Where access to a make-up vessel would be difficult by

pre-pressurisation of the system. Refer to 'Filling.'

GENERAL

SEALED SYSTEM REQUIREMENTS - continued

7. Mains Connection

There must be no direct connection to the mains water supply or to the water storage tank supplying domestic water, even through a non-return valve, without the approval of the local water authority.

8. Filling

The system may be filled by one of the following methods: a. Through a cistern, used for no other purposes, via a

ball valve permanently connected directly to a service pipe and / or a cold water distributing pipe.

The static head available from the cistern should be adequate to provide the desired initial system design pressure. The cold feed pipe from the cistern should include a non-return valve and a stop valve with an automatic air vent connected between them, the stop valve being located between the system and the automatic air vent. The stop valve may remain open during normal operation of the system if automatic water make-up is required.

b. Through a self-contained unit comprising a cistern,

pressure booster pump (if required) and, if necessary, an automatic pressure reducing valve and flow restrictor. The cistern should be supplied through a temporary connection from a service pipe or cold water distributing pipe.

This unit may remain permanently connected to the heating system to provide limited automatic water make-up. Where the temporary connection is supplied from a service pipe or distributing pipe which also supplies other draw-off points at a lower

level then a double check valve shall be installed upstream of the draw-off point.

c. Through a temporary hose connection from a draw-off tap

supplied from a service pipe under mains pressure. Where the mains pressure is excessive a pressure-reducing valve shall be used to facilitate filling.

The following fittings shall form a permanent part of the system and shall be fitted in the order stated:

A stop valve complying with the requirements of BS. 1010, Part 2 (the hose from the draw-off tap shall be connected to this fitting).

A test cock. A double check valve of an approved type.

• Thoroughly flush out the whole of the system with cold water, without the pump in position.

• With the pump fitted, fill and vent the system until the pressure gauge registers 1.5 bar (21.5lb/in

Examine for leaks.

• Check the operation of the safety valve by manually raising the water pressure until the valve lifts. This should occur within ± 0.3 bar (± 4.3lb/in lift pressure.

• Release water from the system until the initial system design pressure is reached.

• Light the boiler and heat the system to the maximum working temperature. Examine for leaks.

• Turn off the boiler and drain the system while still hot.

• Refill and vent the system.

) of the preset

Sizing procedure for expansion vessels: The volume of the expansion vessel (litres) fitted to a sealed system shall not be less than that given by Table 5, multiplied by a factor of 0.8 (for flow temperatures of less than 88 oC).

ELECTRICAL CONNECTIONS

WARNING.

The appliance MUST be efficiently earthed.

A mains supply of 230 V ~ 50 Hz fused at 3A is required.

All external controls and wiring MUST be suitable for mains voltage.

Wiring should be in 3-core PVC insulated cable NOT LESS than

0.75 mm

Wiring external to the boiler MUST be in accordance with current l.E.E. (BS 7671) Wiring Regulations and local regulations. For Ireland reference should be made to the current ETCI rules for electrical installations.

(24 x 0.2 mm) to BS.6500, Table 16.

INSTALLATION

Connection must be made in a way that allows complete isolation of the electrical supply - such as a double pole switch, having a 3mm (1/8") contact separation in both poles, or a plug and socket serving only the boiler and system controls.

The means of isolation must be accessible to the user after installation (except in the case of bathroom installations for domestic boilers where the point of connection to the mains MUST be outside of the bathroom).

INTERNAL WIRING

Flow and pictorial wiring diagrams are shown in Frames 18 and 19.

1. Remove the securing screw and lift off the control box cover.

2. Route the electrical leads into the box and wire into the terminal strip, as shown.

Notes.

a. Secure each lead with one of the cable

clamps.

b. The mains lead connection MUST be made

so that, should the lead slip from its anchorage, the current conductors become taut before the earthing conductor.

LEGEND w white bk black br brown b blue y/g yellow/green

EXTERNAL CONTROLS

External wiring must be in accordance with the current I.E.E. (BS 7671) Wiring Regulations. For Ireland reference should be made to the current ETCI rules for electrical installations.

The wiring diagrams illustrated in Frames 20-22 cover the systems most likely to be fitted to this appliance.

For wiring external controls to the Mexico Super CF boiler reference should be made to the system wiring diagrams supplied by the relevant manufacturer, in conjunction with this flow wiring diagram and Frame 16.

Difficulty in wiring should not arise, providing the following directions are observed:

1. Controls that switch the system on and off, e.g. a time switch, MUST be wired, in series, in the live mains lead to the boiler.

2. Controls that override an on/off control, e.g. a frost thermostat, MUST be wired into the mains lead, in parallel, with the control(s) to be overridden. Refer to Frame 23.

FROST PROTECTION

Central heating systems fitted wholly inside the house do

not normally require frost protection as the house acts as a 'storage heater' and can normally be left at least 24 hrs. without frost damage. However, if parts of the pipework run outside the house or if the boiler will be left off for more than a day or so then a frost 'stat should be wired into the system.

This is usually done at the programmer, in which case the programme selector switches are set to OFF and all other controls MUST be left in the running position.

The frost 'stat should be sited in a cold place but where it can sense heat from the system.

Wiring should be as shown, with minimal disturbance to other wiring of the programmer.

Designation of the terminals will vary, but the programmer and thermostat manufacturers' leaflets will give full details.

Diagram A shows a double pole frost thermostat, which should suffice for all systems which do not use the OFF terminals of the programmer.

Diagram B shows a 'change-over' frost thermostat, which will cover most systems which do use CH OFF. If, however, on such a system the HW pipework is in an isolated part of the house, a second frost thermostat may be used to protect it.

If in doubt, ask your installer for advice.
