GENERAL

GAS SUPPLY

The local gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an adequate supply of gas. An existing service pipe must NOT be used without prior consultation with the local gas supplier.

The boiler is to be installed only on a gas supply with a governed meter.

A gas meter can only be connected by the local gas supplier or by a local regional contractor.

Check that the appliance is suitable for the proposed gas supply. An existing meter should be checked, preferably by the gas supplier, to ensure that the meter is adequate to deal with the rate of gas supply required. A minimum gas pressure of 20 mbar MUST be available at the boiler inlet, with the boiler operating.

Installation pipes MUST be fitted in accordance with BS. 6891. Pipework from the meter to the boiler MUST be of an adequate size.

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

FLUE INSTALLATION

Some pluming may occur at the termination so terminal positions where this could cause a nuisance should be avoided.

The flue must be installed in accordance with the recommendations of BS. 5440:1.

The following notes are intended for general guidance:-

1. The boiler MUST be installed so that the terminal is exposed to external air.

2. It is important that the position of the terminal allows the free passage of air across it at all times.

3. Minimum acceptable spacing from the terminal to obstructions and ventilation openings are specified in Table 3.

4. Where the lowest part of the terminal is fitted less than 2m (6'6") above a balcony, above ground or above a flat roof to which people have access then the terminal MUST be protected by a purpose designed guard. The minimum

Table 3 - Balanced flue terminal position

10. From an opening in a car port

(e.g. door or window) into dwelling 1200 mm (48")

11. Vertically from a terminal on the same wall 1500 mm (60")

12. Horizontally from a terminal on the wall 300 mm (12")

Minimum Spacing

spacing in Table 3, Nos. 2,3, 4, 5 and 6 would be 75mm in order to allow a terminal guard to be fitted.

Terminals guards are available from boiler suppliers - ask for Tower Flue Guard, Model K1. In case of difficulty seek advice from:

Tower Flue Components Ltd., Vale Rise, Tonbridge, Kent TN9 1TB (Model K1) Telephone No. 01732 351 555

Ensure that the guard is fitted centrally.

5. Where the terminal is fitted within 1000mm (39 plastic or painted gutter or 500mm (19 1/2") of painted eaves then an aluminium shield at least 1000mm (39 1/2") long should be fitted to the underside of the gutter or painted surface.

6. The air inlet/products outlet duct and the terminal of the boiler MUST NOT be closer than 25mm (1") to combustible material. Detailed recommendations on the protection of combustible material are given in BS.5440:

1990.

7. Where it is essential that the terminal wall plate is fitted, i.e. wall thicknesses over 600mm (23 cut hole, the minimum spacing in Table 3 Nos. 2,3, 4, 5 and 6 would be 60mm (2 1/2") in order to allow the terminal wall plate to be fitted.

IMPORTANT.

It is absolutely 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. If this should occur, the appliance MUST be turned OFF, labelled 'unsafe' and corrective action taken.

TERMINAL

The terminal assembly can be adapted to accommodate various wall thicknesses. Refer to Frames 7 and 27.

AIR SUPPLY

Detailed recommendations for air supply are given in BS.5440:2. The following notes are for general guidance:

1. It is NOT necessary to have a purpose provided air vent in the room or internal space in which the boiler is installed.

2. If the boiler is to be installed in a cupboard or compartment, permanent air vents are required (for cooling purposes) in the cupboard/compartment, at both high and low levels. The air vents must either communicate with room/internal space, or be direct to outside air. The minimum effective areas of the permanent air vents, required in the cupboard/ compartment, are specified as follows and are related to maximum rated heat input.

3. Both air vents MUST communicate with the same room or internal space or MUST be on the same wall to outside air.

4. In siting the air vents care must be taken to avoid the freezing of pipework.

GENERAL

WATER CIRCULATION SYSTEM

The boiler must NOT be used for direct hot water supply or for sealed systems. 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.

The boiler is NOT suitable for gravity heating systems. The hydraulic resistances of the boilers at maximum output with 11

C (20 OF) temperature differentials are shown in the graph below.

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 and MUST NOT be used on sealed systems.

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.

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 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.

Water Flow Rate and Pressure Loss

1/2" BSP nominal

WATER TREATMENT

The Mexico Super FF incorporates a cast iron heat exchanger. As part of the installation the central heating system should be thoroughly flushed with appropriate water treatment in order to comply with BS7593:1992

Caradon Plumbing Limited recommend the use of Fernox or Betz Dearborn water treatment products which must be used in accordance with the manufacturers instructions. For further information contact :-

Fernox Manufacturing. Co. Ltd., Tandem House, Marlowe Way, Croydon, Surrey CRO 4XS, tel 0870 5601 5000

Betz Dearborn Ltd., Widnes, Cheshire, tel. 0151 424 5351

IMPORTANT.

ANY OTHER TREATMENT FOR THIS PRODUCT WILL RENDER THE GUARANTEE OF CARADON PLUMBING LIMITED INVALID.

Notes.

1. If an inhibitor is used, and in hard water areas where

treatment to prevent lime deposits is necessary, it is most important that the water treatment MUST be maintained at the correct concentrations recommended by the treatment manufacturer.

2. Artificially softened water must not be used in the system, under any circumstances.

THERMOSTATIC RADIATOR VALVES

Caradon Plumbing 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.

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 must be fitted in order to ensure a flow of water should all the valves be in the closed position.

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.

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

1/8") contact separation in both poles, or a plug and socket

3mm ( serving only the boiler and system controls.

The means of isolation must be accessible to the user after installation.

Dotted lines indicate flow rates equivalent to a temperature rise of 11 OC (20 OF)

For bathroom installations the point of connection to the mains must be situated outside the bathroom.

IMPORTANT. Ensure that, during the cutting operation, masonry falling outside of the building does not cause damage or personal injury.

3. Cut the flue hole, preferably with a 125mm (5") core boring tool, ensuring that the hole is square to the wall. If the hole has been quite accurately cut with a drill then making good the wall faces is not essential as seals are provided at both ends of the flue. However, both wall faces immediately around the cut hole should be flat; make good if necessary. For less accurate holes make good to approximately 125mm (5") diameter at the 2 wall faces.

4. Remove the template from the wall.

INSTALLATION

Note.

If the terminal is to be sited within 25-40mm of a corner or vertical pipe (refer to Table 3) then the hole MUST be accurately cut and the rubber weather seal trimmed around the groove provided. The terminal wall plate need not be fitted.

MINIMUM REQUIREMENTS Fully pumped systems

1. Open vent and cold feed connections must be made to the boiler flow and

return tappings according to the options shown in Frame 8.

2. The boiler is assumed to be the highest point of the circulating system.

3. The circulating pump is positioned on the FLOW and the vertical distance, between the pump and feed/ expansion tank, must comply with the pump manufacturer's minimum requirements, to avoid cavitation. Should these conditions not apply, either lower the pump position or raise the feed/ expansion tank above the minimum requirements of Caradon

Plumbing Ltd.

4. The water velocity through the boiler flow / return pipes

is assumed to be below 1 m/s (3 ft./s), whilst the pump flow rate is set to provide a temperature difference of

C (20 oF) across the boiler flow / return, at design

11 input.

5. This information is intended as a GUlDE ONLY and cannot take into account instantaneous changes in head caused by the operation of motorised valves, pumps etc.

Due allowance MUST be made if surging is liable to occur.

If in any doubt, contact Caradon Plumbing Ltd.

INSTALLATION

GRAVITY HOT WATER & PUMPED CENTRAL HEATING

1. Separate flow and return connections are used for each service.

All possible configurations are given in Frame 8 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 100 mm (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.

If the above conditions cannot be met pumped primaries should be used.

INTERNAL WIRING

Flow and pictorial wiring diagrams are shown in Frames 45 and 46. A schematic wiring diagram is included in the Lighting Instruction label.

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.

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.

This connection should be readily accessible and be made adjacent to the boiler (except in the case of bathroom installations for domestic boilers where the point of connection to the mains MUST be outside of the bathroom.)

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 manufacturer's leaflets will give full details.

Diagram A shows a double pole frost thermostat, which

INSTALLATION

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.

FITTING THE CASING

1. Offer up the RH side panel, locating it with the

peg in the baseplate, and push the panel back engaging it into the collector hood tab.

2. Secure the panel to the baseplate and turret front panel.

3. Repeat steps 1 and 2 to refit the LH side panel.

4. Place the top panel and push back.

5. Secure the top panel to the side panels.
