3 Introduction. Welcome to the range of or-ray-vac LR series continuous radiant tube heaters. The or-ray-vac LR series system complies with the requirements of the European Gas Appliance Directive BS E Local regulations may vary in the country of use and it is the installers responsibility to ensure that such regulations are satisfied. All installation, assembly, commissioning and service procedures must be carried out by suitable qualified competent persons to the statutory regulations in the country of use. When assembling, installing, commissioning and servicing is undertaken on radiant tube heaters specified in these instructions, due care and attention is required to ensure that working at height regulations are adhered to at the mounting heights specified. PLEASE READ this document prior to installation to familiarise yourself with the components and tools you require at the various stages of assembly. number of radiant branches manifolded together, linked by a tail pipe to a vacuum fan discharging the spent products of combustion to atmosphere. A system may comprise of just one burner and one vacuum fan, to multiple burners in multiple radiant branches with one or more vacuum fans. To enable exact matching of operational needs within an area, distances between burners and ratings of the burners can vary. The unique feature of or-ray-vac LR series is a radiant system which provides uniform heat coverage of the floor area, eliminating hot/cold spots. The tube into which the burners are mounted and over which the reflectors are fitted and emits the maximum heat is called the radiant tube. The radiant heat emitted from the hot tube is directed downwards by reflectors. The remaining interconnecting tube is called the tail pipe and radiates with less intensity. The operating temperatures of the tubes generally range from 00 C 480 C max. All Dimensions shown are in mm unless otherwise stated. The manufacturer reserves the right to alter specifications without prior notice. The Ambi-Rad or-ray-vac LR series direct gas fired radiant heating system comprises of a continuous system with a number of burners located in series in a radiant branch, and a. Installation Requirements. The action of the vacuum fan is three fold; to create a high negative pressure within the radiant tube and tail pipe so as to discharge the spent products of combustion from the system to a point outside the building being heated; to control the flow of gas and air through each burner in stoichiometric proportions; to draw carrier air into the tube system at the start of each radiant branch, in order to distribute the heat from the flame along the tube. Isolate any electrical supply to the heater and controller before proceeding.. Health and Safety AmbiRad heaters must be installed in accordance with the relevant provisions of the Gas Safety (Installations and Use) Regulations 998. Due account should also be taken of any obligations arising from the Health and Safety at Works Act 974 or relevant codes of practice. In addition the installation must be carried out in accordance with the current IEE wiring regulations (BS 767), BS 6896: (Industrial & Commercial) and any other relevant British Standards and Codes of Practice by a qualified installer. Isolate all electrical supplies to the heater & controller before proceeding. 3 The system is assembled at high level suspended by chains from first fixings to the roof structure. (First fixings by others) For your own safety we recommend the use of safety boots and leather faced gloves when handling sharp or heavy items. The use of protective eye wear is also recommended.. Burner Model Definitions RVxxLR-EV = or-ray-vac continuous radiant tube heater only for use with branch end configurations. RVxxLR-IL = or-ray-vac continuous radiant tube heater only for use with in-line configurations. xx denotes kw rating. Models available;, 8, 4, 3, 38 and 46

4 .3 Heater Suspension.3. First considerations Clearances from combustibles must be maintained. (See figure ) For ease of servicing there should be a minimum clearance distance of 500mm between the burners of the heating system and the building wall. This measurement can be reduced for perimeter type systems. (See figure a). For ease of servicing and burner removal minimum clearances should be maintained. (See figure b and c). In exceptional circumstances the burner lid may be slid diagonally for removal thus reducing the vertical distance. Ensure that the suspension is sufficiently flexible to allow for thermal expansion..3. Suspending the heater - General.3.. The first support is always positioned at the support lug suspension point on the end vent burner combustion chamber..3.. Subsequent supports are placed approximately.8m apart, including one at each combustion chamber location. This gives a maximum load per support of 4kg A support must always be located at a maximum distance of m from a tee or elbow fitting Except for the combustion chamber support lug suspension points, suspension support brackets are installed to support the tube section which is then covered with reflectors Tail pipe hangers are installed for the tube section which will be without reflectors. If there are any doubts as to the strength or suitability of roof steelwork to which heaters are to be suspended, please refer to a Consultant, Architect or owner of the building. Table.

7 .5 Gas Connection and Supply Before installation, check that the local distribution conditions, nature of gas and pressure, and adjustment of the appliance are compatible. A competent or qualified engineer is required to either install a new gas meter to the service pipe or to check that the existing meter is adequate to deal with the rate of gas supply required. Installation pipes should be fitted in accordance with BS 6896, so that the supply pressure, as stated in Table 3 will be achieved. It is the responsibility of the competent engineer to ensure that other relevant Standards and Codes of Practice are complied with in the country of installation. Pipes of smaller size than the heater inlet gas connection must not be used. The complete installation must be tested for soundness as described in the country of installation. The gas union service cock MUST be fitted in the gas supply close to the heater, but not onto the burner itself. Take care when making a gas connection to the heater not to apply excessive turning force to the internal controls. A flexible hose is installed to allow safe linear expansion to each burner without creating undue stress on the gas supply pipe work. It is therefore important that a tested and certified hose assembly made to ISO 0380, supplied with ½ BSP female cone seat adapters, is installed as per these instructions. It is also important to ensure that expansion is taken up in the body of the flexible hose, and not on its attachment to the pipe work. The cone seat adapter supplied on one end of the flexible gas hose provides a `swivel` action, and must be fitted on the burner using a ½ BSP barrel nipple to provide ease of disconnection for future servicing. The installation layout described below is the only method recommended by the institute of gas engineers, the hose manufacturer, and AmbiRad and must only be carried out by a qualified/competent gas engineer.

Correct Installation of Flexible Gas Connection fig.a fig.b x fig.c x Depending on the specific installation, the flexible gas hose may be routed to the gas cock at any of the following angles in relation to the burner: Arrow denotes direction of expansion. Vertical (fig.a) 45 angle (fig.b) 90 angle (fig.c) Any other position in between these angles is acceptable. fig.d Care must be taken to observe the minimum pipe bend diameter (minimum 50mm, maximum 350mm) & pipe expansion distance (minimum 30mm, maximum 70mm) as shown in fig.e. 50 +/- 0mm Maximum bend diameter for the hose is 450mm /- 50mm The correct installation as shown will allow for approx 00mm of movement due to expansion. Burner fig.e fig.f fig.g The methods shown in fig.f and fig.g are unacceptable, due to undue stress on the hose & fittings. 8

9 .6 Electrical Connections Standard burner 6W. Current rating 0.05 amp per burner Fuse: external 3 amp. Each component carrying an electrical supply must be earthed. Supply for burners is 30V 50Hz single phase. * Exhaust fans are three phase 45V 50Hz. * IP54 rated Inverter panel LRU s require a 30V single phase supply at A (B80/ B60) or 30A (B300) * Standard LRU s require a 45V three phase supply at 5A (BH300) * refer to individual site specifications All electrical work should be carried out to IEE standards by a competent electrician. The electrical connection to the burner is made by means of a three pin plug-in power connector. Live, neutral and earth connections should be made via a flexible supply cable to the power connector and routed clear of the heater or tubes. The flexible supply cables to each burner should be of 0.5mm² minimum and comply with BS For fan and LRU supply, the wire size must be suitable for the current ratings as listed in Table 0. The wires in the mains lead are coloured in accordance with the following code: Green & Yellow Earth; Blue eutral; Brown Live The method of connection to the electrical supply must facilitate complete isolation and should be via a fused double pole isolator having contact separation of at least 3mm on all poles and supplying the appliance only. We recommend use of AmbiRad approved controls.

19 .7 Ventilation Requirements.8. Vertical discharge or-ray-vac heaters are installed as flued appliances in accordance with the relevant national requirements in the country of installation. In buildings having an air change rate of less than 0.5 per hour, additional ventilation is required. For detailed information, please see BS6896 section 5... atural Ventilation Low level ventilation openings with a free area of at least cm²/kw shall be provided. See BS6896 section Exhaust and Air Inlet - Options.8. Horizontal discharge Considerations. The vacuum fan must be located as shown in the layout drawing. The vacuum fan must have a bottom horizontal discharge. The fan should be fitted to the mounting platform which is fixed to the wall or building structure. Alternatively, the fan can be suspended from the roof structure, via drop rods (not supplied) and mounted on base frame. (Anti-vibration mountings are fitted between the fan and the mounting platform/base frame. For full details of parts and installation, please refer to section.9.3 9

To Switch Off Heater.3 Routine Maintenance between Service Intervals After ensuring that the heater is cold and mains electric isolated, cleaning of the reflectors with a soft cloth and a mild detergent (non solvent based cleaners only) in water can be undertaken. Additional removal of dust from the radiant tubes, burner and heat exchanger can be undertaken..4 Frequency of Servicing The manufacturer recommends that to ensure continued efficient and safe operation of the appliance, the heater is serviced annually by a competent person e.g. every year in normal working conditions but in exceptional dusty or polluted conditions more frequent servicing may be required. The manufacturer offers a maintenance service. Details are available on request. For Service requirements, please contact AmbiRad. For further technical and service support visit our Support Information Database at Switch off electrical supply to the heater. The burner will stop and the fan will shut off.. If the heater is to be switched off for periods in excess of one week it is highly recommended that both the gas and the electrical supplies are turned off. ote This notice must be fixed alongside the electrical service switch. On some systems only the end vent burner contains a delay timer. In this instance the inline burners will light simultaneously and the end vent burners will light after an 80 seconds delay.
