  • Page 10 1-WARNINGS AND WARRANTY CONDITIONS RULES FOR INSTALLATION The product is a boiler that uses wood pellets. Below is a list of the European regulations regarding the installation of the product: EN 303-5:2012: Solid fuel boilers, with manual or automatic loading, nominal thermal power of 500 kW - Terminology, requisites, tests and marking.

  • Page 11: 2-Installation Instructions

    2-INSTALLATION INSTRUCTIONS The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the domestic regulations in force. PELLETS Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders.
  • Page 12 2-INSTALLATION INSTRUCTIONS PRECAUTIONS REGARDING INSTALLATION IMPORTANT! Product installation and assembly must be carried out by qualified personnel. The product must be installed in a suitable place that allows easy access for it to be opened regularly and for routine maintenance to be performed.
  • Page 13 2-INSTALLATION INSTRUCTIONS POSITIONING AND RESTRICTIONS In the case of simultaneous installation with other heating appliances, provide appropriate air inlets for each one (according to the instructions of each product). Installation of the product is not permitted: • in rooms where there are liquid fuel appliances with continuous or intermittent operation that draw the combustion air from the room they are installed in;...
  • Page 14 2-INSTALLATION INSTRUCTIONS FOREWORD This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856 - EN1457). The chapter provides indications for installing an efficient and correct smoke flue but is under no circumstances to substitute the regulations in force, which the qualified technician must be in possession of.
  • Page 15 2-INSTALLATION INSTRUCTIONS TECHNICAL CHARACTERISTICS Flues serving a pellet/wood fuelled appliance must meet the following requirements: • made of materials that are sufficiently resistant to mechanical stress, heat, the action of the products of combustion and their vapours. • made of materials that are impermeable to fumes, condensation, be thermally insulated and resistant to normal mechanical stress over time •...

  • Page 17 2-INSTALLATION INSTRUCTIONS DIMENSIONING The drop in pressure (draft) of a flue depends on its height. Check the drop in pressure with the values indicated in the technical characteristics. The minimum height of the chimney is 3.5 meters. The interior cross-section of the flue can be circular (best variation), square or rectangular (the ratio between the interior sides must be ≤1.5) with the sides joined with a minimum radius of 20 mm.
  • Page 18 2-INSTALLATION INSTRUCTIONS MAINTENANCE The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the efficient functioning of the heater and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and checked by a skilled chimney sweep at least once a year.
  • Page 19 2-INSTALLATION INSTRUCTIONS CONNECTION TO FLUE The connection between the flue and the appliance must be via a smoke duct that conforms with EN 1856-2. The connecting section must extend no more than 4 m horizontally, with a maximum incline of 3% and containing a maximum of 3 90% bends (accessible for inspection - do not count the T joint at the appliance outlet).
  • Page 20 2-INSTALLATION INSTRUCTIONS EXAMPLES OF CORRECT INSTALLATION 1. Installation of Ø 150 mm flue with hole for the passage of the pipe increased by: minimum 100 mm around the tube if next to non flammable parts such as cement, brick, etc.; or minimum 300 mm around the tube (or as prescribed by data tags) if next to flammable parts such as wood etc.

  • Page 24: 4-Unpacking

    4-UNPACKING PREPARATION AND UNPACKING The Compact Easy Clean boiler is delivered complete with all its electrical, mechanical and hydraulic components (excluding the circulator kit and thermostatic valve-OPTIONAL) and having been tested in the factory: Box 1 contains the structure of the boiler, while box 2, on top of the packaging, contains the trolley (to make it easier to move and remove ash) and the compressor, required to turn on the turbulators.
  • Page 25 4-UNPACKING Install the boiler in the area set aside for it, making sure it conforms to the requirements. The boiler body or unit must always be kept in a vertical position when moved, and only ever moved using suitable lifting trolleys. The packaging materials are neither toxic nor harmful, and therefore no particular disposal measures are required.
  • Page 26 4-UNPACKING The end user is responsible for product storage, disposal or possible recycling in compliance with the relative applicable laws in force. Position the product and proceed with connecting it to the chimney. If the product must be connected to an exhaust pipe that goes through the rear wall (to enter the chimney), make sure not to force it in. Attention!! If the boiler smoke outlet is forced or used improperly to lift it or position it, the operation of the stove can be damaged irreparably.

  • Page 27: 5-Positioning

    5-POSITIONING REQUIREMENTS FOR INSTALLATION OF THE PLANT - POSITIONING The most important thing to do before installation of the boiler is to set aside a suitable area that meets the minimum requirements for installation. • the minimum clearance in front of the product for the purpose of cleaning, maintenance, etc. must be 1000 mm; •...

  • Page 32: 9-Hydraulic Connection

    9-HYDRAULIC CONNECTION PLUMBING CONNECTION IMPORTANT: The connections depend on the type of System Configuration. IMPORTANT! If installing the boiler involves another pre-existing system complete with heating equipment (gas boiler, methane boiler, fuel oil boiler, etc.), it is strongly recommended that you contact a qualified operator who subsequently will be responsible for the compliance of the system with the applicable laws in force.
  • Page 33 Standard UNI 8065 (water treatment of thermal plants for civil use). As standard, RED supplied the product FERNOX PROTECTOR F1 with the product. This provides long term protection against corrosion and calcium build-up for the heating appliance. It prevents the corrosion of the metal parts of the appliance, i.e.
  • Page 34 A higher return temperature reduces the formation of condensation of the fumes and extends the life of the boiler. Valves available offer various calibrations. RED recommends the model (see accessories list) at 55°C with hydraulic connections of 1". Once the calibration temperature is reached, the valve opens thereby supplying hot water to the system.

  • Page 35: 10-Electrical Connections

    10-ELECTRICAL CONNECTIONS GENERAL PRECAUTIONS The electrical safety of the system is guaranteed only when this is connected correctly to an efficient earthing system installed in accordance with the safety standards in force: the pipes of the gas, water and heating systems do not constitute a suitable earth system. It is necessary to ensure this essential safety requirement;...

  • Page 36: 11-First Start-Up

    11-FIRST START-UP BEFORE START-UP GENERAL PRECAUTIONS Remove all parts that may burn from the brazier and the product's tank (manual, various adhesive labels or any polystyrene). Make sure all the refractory materials are positioned correctly and they do not obstruct the combustion chamber. The first start-up may not be successful as the feed screw is empty and does not always manage to load the required amount of pellets in time to light the flame.
  • Page 37 11-FIRST START-UP The boiler will be subject to expansion and contraction during the stages of lighting and cooling down, and may therefore make slight creaking noises. This is absolutely normal as the structure is made of laminated steel and must not be considered a defect. It is extremely important to make sure the boiler does not reach high temperatures straight away, but to increase the temperature gradually using low power at first.
  • Page 38 11-FIRST START-UP LOADING THE PELLETS The pellets can be loaded either manually or automatically. The tank can contain up to 150 litres or 100 kg of pellets. Manual Loading: • Open the top cover of the boiler and pour in the pellets. Automatic loading (with remote tank of 100/200 or 400 kg - optional - see accessories): •...
