PR EPERAT IO N 1. Load Check A load check must be taken into consideration when installing high power boilers. This can be carried out by a qualified electrician. There may be a requirement to upgrade the main incoming fuse supplying the property; this will depend on the boiler output being installed and existing electrical load requirements of the property. 2. Boiler location The boiler must be installed onto a wall that will provide an adequate fixing. Precautions must be taken if the boiler is to be installed in areas subject to damp or frost conditions. 3. Central heating (design & installation) Detailed recommendations are given in BS EN 12828, BS 6700: +A1 and CP 342-2. Pipes forming part of the useful heating surface should be insulated to prevent any potential heat loss or frost damage. (BS 6700). Drain valves should be fitted at the lowest point of the system pipe work in an accessible position. Drain valves should be in accordance with BS 2879 and copper tube to BS EN 1057 is recommended. LO CAT I ON The boiler can be installed in almost any location within a domestic or commercial property; however con- sideration should be made for future maintenance. Never leave the boiler switched off if there is a danger of having temperatures below 0°C in the room where it is located, (An additional frost stat must be used if there is a likelihood of the temperature falling below 0°C). We recommend that a minimum clearance of 400 mm should be allocated for the removal of the front cover to allow adequate access to the boilers plumbing and the internal electrical connections. A 50mm allowance should be made at either side of the boiler to allow free flow air into the boiler. The boiler must be installed in the upright position; failure to do so will invalidate the Warranty! GB-063C_f.615...

An auto air vent must be fitted to the external pipe work when installed in an unvented system. Do not install AAV’s directly above the SlimJim boilers. AAV’s should be installed to either the top left or right hand side of the boilers. (This is to prevent any water entering the boiler in the event of an AAV leaking).
We recommend the use of an automatic bypass within this circuit. If a bypass radiator is used an allowance should be made for a minimum radiator size of 600mm x 600mm single convector or equal to 2500 Btu to be installed within the heating circuit and locked open. (This will be located in the room where the thermostat is installed). To comply with building regulations, Part L and Part J (in Scotland), room and cylinder thermostats must be fitted. Water Connections Provisions must be made for the replacement of water lost from the heating system (sealed systems). Reference should be made to BS EN 14336 for the method of filling and make up of water. There must be no direct connection between the boilers central heating system and the main water supply. When mains water is required to fill the system directly, all local water bylaws must be observed, and any connection made must be disconnected after use. 10. Flushing The system must be flushed to within 10% of mains water PPM to ensure that no debris is trapped in the flow sensor as this may result in boiler failure. Where existing radiators and pipe-work are utilised a power flush must be carried out to remove debris. 11. System Pressures All boilers are pressure tested in the factory. The normal working pressure of the boiler should be set to approx 1.0/1.5 bar. All sealed systems should comply with the relevant building regulations and standards, including BS EN 13831 - Specification for Expansion Vessels. It is imperative that a pre-installed magnetic filter is removed and cleaned annually. Failure to carry out this action will increase contamination of the boiler by the system residue.

IN STAL L AT IO N 12. System types The “Slim Jim” boiler range can be used in various system designs including under floor systems. There are two heating schematics on page 10 Figure 1 & 2 that illustrate an Indirect System (S Plan) & Direct System (Heating Only). We recommend the use of Thermostatic Radiator valves on all radiators excluding the bypass radiator; this radiator should be fitted with lockshield valves and left in the fully open position. In addition we recommend that an automatic bypass is used in zoned systems and set to the relevant flow rates required for the system design. (The bypass radiator should be a minimum size of 600mm x 600mm single convector or equal to 2500 Btu to be installed within the heating circuit and locked open. This will be located in the same area as the room thermostat). The system design should meet all current building regulations in force at the time of installation. 13. Hanging the Boiler 1 Take care when removing the boiler from its packaging. Do not open with sharp objects as this may damage the unit.

ELEC TR IC AL CO NNECT I ONS All wiring must be carried out in accordance with current IEE wiring regulations BS:7671 (all electrical connections must be made by a qualified tradesperson). LOAD CHECK A load check must be taken into consideration when installing high power boilers. This will be carried out by a qualified electrician. There may be an additional requirement to upgrade the incoming main fuse supplying the property if other high power devices are used within the property. E.g Electric Showers. If an electric shower is present we recommend that a Shower Sensor is installed within the system. This will cause an interrupt to the boilers control signal when the shower is in use. It will disable the boiler protecting the electrical system from overload.

External Control Options: The Slimjim boilers can be used with Volt Free or 240 volt control signals. Volt Free control operation. Remove the link from the RP Connection (10) and connect your external volt free control cables here. When this connection is “Closed” the boiler will fire, and when “Open” the boiler will be in standby. (The control enable dip switch 4 must be in the OFF position as shown in the table below). 240 volt control operation. The link must be left in the RP Connections (10) and a live SW and Neutral connected to the control terminals (11) To enable the feature you must select Dip 4 to ON. This is located at the top LHS of the control Board. (The control enable dip switch 4 must be in the ON position as shown in the table below). Boiler Output Control. You can control all SlimJim boilers power outputs in 3 stages by selecting dip switches settings as shown in the table below. e.g. If a 6kW is used and dip switch 1 on = 2kW Output – 6kW boiler dip switch 1&2 on = 4kW Output – 6kW boiler dip switch 1,2&3 on = 6kW Output.
