The Electricity at Work Regulations, 1989.
Manufacturer's notes must NOT be taken in any way as overriding statutory obligations.
IMPORTANT. These appliances are certificated by the British Standards Institution for safety and performance. It is, therefore, important that no external control devices, e.g. flue dampers, economisers etc., are directly connected to these appliances - unless covered by these 'Installation and Servicing' instructions or otherwise recommended by Caradon Heating Ltd, in writing. If in doubt please enquire.
Any direct reconnection of a control device not approved by Caradon Heating Ltd., could invalidate the B.S.I. Certification and the normal appliance warranty. It could also infringe the Gas Safety Regulations and the above Regulations.
The boiler MUST be installed on a flat and vertical wall, capable of adequately supporting the weight of the boiler and any ancillary equipment.
The boiler may be fitted on a combustible wall and insulation between the wall and the boiler is not necessary - unless required by the Local Authority. THE BOILER IS NOT SUITA-BLE FOR EXTERNAL INSTALLATION.
IMPORTANT NOTICE. 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 DM2. If in doubt advice must be sought from the Local Gas 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 then the appliance and 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.
Where installation will be in an unusual location, special procedures may be necessary and BS. 6798 gives detailed guidance on this aspect.
A compartment used to enclose the boiler MUST be designed and constructed specially for this purpose. An existing cupboard or compartment may be used, provided it is modified for the purpose. Details of essential features of cupboards / compartment design, including airing cupboard installation are given in BS. 6798. In siting the boiler, the following limitations MUST be observed:
The Local Gas Region 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 Region.
A gas meter can only be connected by the Local Gas Region or by a Local Region Contractor.
An existing meter should be checked, preferably by the Gas Region, to ensure that the meter is adequate to deal with the rate of gas supply required.
Installation pipes MUST be fitted in accordance with BS. 6891. Pipework from the meter to the boiler MUST be of an adequate size. Do NOT use pipes of smaller size than the boiler inlet gas connection.
The complete installation MUST be tested for gas soundness and purged as described in the above Code.

Caradon Heating Ltd. 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, then a by-pass must be fitted in order to ensure a flow of water should all the T.R.V.s be in the closed position.
Wiring external to the appliance MUST be in accordance with the current I.E.E. Wiring Regulations and any Local Regulations which apply.
The boiler is supplied for 240 V ~ 50 Hz
Single Phase
Fuse Rating is 3 A
The method of connection to the mains electricity supply MUST facilitate complete electrical isolation of the boiler, preferably by the use of a fused, unswitched three pin plug and a shuttered socket outlet, both complying with the requirements of BS. 1363.
Alternatively, a fused double pole switch, having at least a 3 mm (1/8 in.) contact separation in both poles and servicing only the boiler, may be used.
The point of connection to the mains should be readily accessible and adjacent to the boiler, except that for bathroom installations; the point of connection to the mains MUST be situated outside of the bathroom.
Note. Where a room sealed appliance is installed in a room containing a bath or shower then the appliance and any electrical switch or apppliance control utilising mains electricity should be so situated that it cannot be touched by a person using the bath or shower.

The system should be vented directly off the boiler flow pipe, as close to the boiler as possible. The cold feed entry should be inverted and MUST be positioned between the pump and the vent, and not more than 150 mm (6 in.) away from the vent connection.
There should be a minimum height - 450 mm (18 in.) of open vent above cistern water level. If this is impossible refer below.
The vertical distance between the highest point of the system and the feed/expansion cistern water level MUST not be less than 450 mm (18 in.).
The pump MUST be fitted on the flow side of the boiler.
A suitable pump is a domestic circulator capable of providing an 11°C (20°F) temperature differential (e.g. Grundfos UPS 15 /50 or equivalent). The vertical distance between the pump and feed / expansion cistern MUST ccomply with the pump manufacturers minimum requirements to avoid cavitation. Should these conditions not apply, either lower the pump position or raise the cistern above the minimum requirement specified by Caradon Heating Ltd. Note: A cold water feed must be available back to the boiler, when all automatic valves are in the closed position (Refer BS. 6798) and when close coupled the feed must not be in a verical leg.
The Ideal Classic range of boilers can be installed in low head situations by fitting a 'surge arrester' in the expansion pipe - as shown.
The following conditions MUST be observed;
The following minimum clearances must be maintained for operation and servicing.
Additional space will be required for installation, depending upon site conditions..
(a) Provided that the flue hole is cut accurately, eg. with a core drill, the flue can be installed from inside up to 610 mm (24 in.), but with flue lengths greater than the width / depth of the boiler then the space in which the boiler is to be installed must be at least equal to the flue length plus the length of the terminal grille.
Front clearance: 450 mm (17 3/4 in.) from the front of the boiler casing.
IMPORTANT. Ensure that, during the cutting operation, masonry falling outside of the building does not cause damage or personal injury.
