overview These instructions are suitable for CLAS HE boilers : Do not forget the Log Book! MTS supports Benchmark, the heating industry code to ensure the correct installation, commissioning and servicing of domestic central heating systems. To The Householder Make sure you have a completed Log Book for your boiler. This provides a record of the commissioning of your boiler. It contains important information about your particular installation that may be required by service engineers.
overview Advice for the installer The installation and first ignition of the boiler must be performed by qualified personnel in compliance with current national regulations regarding installation, and in conformity with any requirements established by local authorities and public health organisations.
overview Safety regulations Key to symbols: Failure to comply with this warning implies the risk of personal injury, in some circumstances even fatal Failure to comply with this warning implies the risk of damage, in some circumstances even serious, to property, plants or animals. Install the appliance on a solid wall which is not subject to vibration. Noisiness during operation. When drilling holes in the wall for installation purposes, take care not to damage any electrical wiring or existing piping.

installation Reference Standards In the United Kingdom, the installation and initial start-up of the boiler must be by a CORGI registered installer in accordance with the installation standards currently in effect, as well as with any and all local health and safety standards i.e. CORGI. building within the vicinity and consideration must also be given to adjacent boundaries, openable windows should also be taken into consideration when siting the flue.
installation Water Supply The boiler is suitable for sealed systems only. The maximum working pressure for the appliance is 6 bar. All fittings and pipework for the appliance should be of the same standard. If there is a possibility of the incoming mains pressure exceeding 6 bar, particularly at night, then a suitable pressure limiting valve must be fitted. The boiler is designed to provide hot water on demand to multiple outlets within the property.
installation ii) Connecting into the waste system of the building such as a washing maching or sink trap. The connection must be upstream of the washing machine/sink. If the connection is down stream of if the waste trap then an additional trap giving a minimum water seal of 75mm and an air break must be incorporated in the pipe run, as above. 3. External termination of condensate drainage pipe via internal discharge branch (e.g. sink waste - proprietary fitting).
installation Installing the Boiler Please check that you are familiar with the installation requirement before commencing work (pages 7 - 11).
installation Gas connection Make sure, using the labels on the packaging and the data plate on the appliance itself, that the boiler is in the correct country and that the gas category for which the boiler was designed corresponds to one of the categories available in the country where it will be used.
installation To calculate the size of the heating installation, refer to the "Available pressure" graph below. Graph representing the available circulation pump pressure ΔT20oC Water circuit diagram mbar 500 450 1 2 400 350 21 4 24 kW 250 22 3 30-38 30-35 kW kW 300 200 150 100 50 5 20 0 0 100 200 300 400 500 600 700 800 900 1000 1100 1200 l/h Before the first time the equipment is used, the trap must be filled with water.
installation Connecting the Flue Flue System The provision for satisfactory flue termination must be made as described in BS 5440-1. The appliance must be installed so that the flue terminal is exposed to outdoor air. The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the position of the terminal allows a free passage of air across it at all times.
installation Warning The exhaust gas ducts must not be in contact with or close to inflammable material and must not pass through building structures or walls made of inflammable material. When replacing an old appliance, the flue system must be changed. Important Ensure that the flue is not blocked. Ensure that the flue is supported and assembled in accordance with these instructions. Installation without extension 118 Level 150 mm Fig.
installation Clamp Screws Seal Fig. 4 Fitting the 5” Flue (Ø 80 / 125 Horizontal/vertical) Once the boiler has been positioned on the wall, it is necessary to insert the Ø80/125 adaptor (Fig. 5) for both horizontal and vertical flue runs into the boiler flue socket (not supplied with flue kit - Part No 3318095). Push the adaptor onto the boilers flue connection, grease the seals then add extensions or elbows as required, secure the adaptor, using the clamp and screws provided.
installation Fitting the Coaxial Flue (Ø 60 / 100 Vertical) Note: See table for maximum and minimum flue runs. Contents: 1x Silicone O-Ring (60mm) 1x Conical Adaptor (60/100mm) 1x Vertical Flue Kit (80/125mm) 3x Screws The vertical flue kit is supplied with a specially designed weather proof terminal fitted, it can be used either with a flat roof or a pitched roof. 180 mm The Vertical flue kits useable lengths with the pitched roof flashings are indicated in Fig. 7.
installation Fitting the Twin Pipe (Ø80 / 80) When siting the twin flue pipe, the air intake and exhaust terminals must terminate on the same wall, the centres of the terminals must be a minimum of 280 mm apart and the air intake must not be sited above the exhaust terminal (refer to Fig. 10). The air intake pipe can be run horizontally, however, the terminal and the final 1 metre of flue must be installed either horizontally or with a slight fall away from the boiler to avoid rain ingress.

For twin flue systems the maximum development value, mentioned in the table includes the exhaust gas/air intake terminal. Type 5 outlets should respect the following instructions: 1- Use the same ø 80 mm flue pipes for the air intakes and exhaust gas ducts.

installation WARNING Before performing any work on the boiler, first disconnect it from the electrical power supply using the external bipolar switch and remove the fuse. Electrical connections For increased safety, ask a qualified technician to perform a thorough check of the electrical system. The manufacturer is not responsible for any damage caused by the lack of a suitable earthing system or by the malfunctioning of the electricity mains supply.

The display shows: The operating mode will be indicated by the three figures marked out on the diagram above. The first figure indicates the operating mode: 0 XX - Stand-by, the scrolling text show the operation mode selected “summer” or “winter” C XX - “C.
commissioning Heating ignition delay adjustment This parameter – menu 2/sub menu 3/parameter 5 - can be used to manually (0) or automatically (1) set the delay time before the subsequent reignition of the burner after it has switched off on reaching the desired temperature in central heating mode. By selecting manual, it is possible to set the delay in minutes using the successive parameter (menu 2/sub menu 3/parameter 6), to a time between 0 and 7 minutes.
commissioning Test function and combustion analysis The boiler has two pressure taps to measure the combustion gas temperature, the combustive air and the concentrations of O2 and CO2 on the outside of the flue gas header. to access these pressure taps, unscrew the screw which holds the blanking cover and its seal together. Wait for the boiler to stabilise before carrying out the combustion analyses. Check the CO2 value according to the table below.
commissioning AUTO function This is a function which enables the boiler to automatically adapt its operation routine (the temperature of the heating elements) in line with the outdoor conditions, in order to achieve and maintain the requested room temperature conditions. Depending on the peripheral units connected and the number of zones controlled, the boiler adjusts its flow temperature automatically. The various corresponding parameters should therefore be set (see adjustments menu).
boiler protection devices Malfunction warning This warning is shown by the display in the following format: 5 P1 = FIRST IGNITION ATTEMPT UNSUCCESSFUL the first figure indicating the operational assembly is followed by a P (warning) and the code relating to the specific warning. Important If this shutdown occurs frequently, contact an authorised Technical Service Centre for assistance.
