    Safety Standards in force. They will be responsible for the definitive installation of the machinery and its consequent proper operation. KLOVER srl will not be held responsible if these precautions are not respected.  During installation of the appliance all local regulations, included those referring to National and European Standards, must be followed.

  • Page 7: Destination Of Use

  • Page 13: Requisites Of The Place Of Installation

    REQUISITES OF THE PLACE OF INSTALLATION Positioning The initial phase for the best installation of the boiler is to determine its optimal location; the following data needs to be considered for this:  An external air vent can be made; ...

  • Page 14: Flue And Connection To The Same - Chimney

    If it is not possible to realise the air vent in the wall behind the boiler, make the hole in a perimeter wall where the boiler is installed. If it not possible to realise the external air vent in the same room where the boiler is installed, this hole can be made in an adjoining room as long as this room communicates permanently, by means of a transit hole (15 cm minimum diameter).
  • Page 15  Preferably circular internal section: squared and rectangular sections must have rounded angles with radius larger than 20 mm;  Constant, free and independent internal section;  Rectangular sections with 1.5 maximum ratio between the sides;  If the flue is installed externally or in a cold room (e.g. boiler room) it is absolutely necessary that it is insulated to avoid the flue gas cooling and condensate forming;...
  • Page 16 FURTHER SPECIFICATIONS TO BE CONSIDERED The boiler functions with the combustion chamber in depression; it is fundamental that the exhaust is hermetically sealed. It is recommended to use rigid stainless steel pipes, with sealing gaskets, with diameter of 120 mm. The pipes must have a double wall or be suitably insulated with rock wool.

  • Page 17: Electric Connections

    During the final wiring of the circuit, only use components with a suitable electric protection rating. KLOVER srl declines all responsibility for injury to persons, animals or damage to objects deriving from failure to connect the boiler to earth and failure to comply with IEC Standards.

  • Page 18: Connection To Room Thermostat

    Below find a connection example using a 3-way valve with spring return. Remember that the hydraulic connection must be made in a way that when the valve is at rest, the water passes from the gas boiler. Only when the pellet boiler temperature is sufficient (value set from control panel), the 3- way valve is powered and therefore closes the gas boiler circuit and opens the Pellet Boiler circuit.

  • Page 19: Hydraulic Connection

    HYDRAULIC CONNECTION The hydraulic connections must be made in a rational way using the connections on the boiler template. To ease connection of the pipes, we have prepared all hydraulic connections on the rear, leaving space to make the connections easily. The boiler can be coupled to any other boiler already installed in the system;...

    CONNECTION EXAMPLE WITH DOMESTIC HOT WATER STORAGE COUPLING These diagrams are purely indicative and do not imply any commitment or responsibility by KLOVER s.r.l. or by its partners. The executive designing and the consequent activation must be carried out according to the regulations in force.

  • Page 21: Cleaning And Maintenance

    CLEANING AND MAINTENANCE Precautions before cleaning Before carrying out any cleaning or maintenance, make sure that:  The boiler is off and has cooled down completely;  The ash is completely cold;  Before re-starting the boiler, re-install all previously disassembled components. During the cleaning operations, use the individual protection devices envisioned by the 89/391/EEC Directive.

  • Page 22: Extraordinary Cleaning

    Empty the ash drawer. ATTENTION: use suitable “bin” type vacuum cleaners, with fine mesh filter, in order to prevent part of the ash from being spilled back out into the environment and damage the suction device itself. Extraordinary cleaning To be performed at least every 30 days. Carry out routine cleaning;...
  • Page 23 Remove the 4 flue deflectors (2 on the right and 2 on the left) from the sides of the combustion chamber and, by means of a spatula, scrape the inner wall surfaces and then suck up any possible deposit.
  • Page 24 After removing the 4 flue deflectors, clean the flue (both right and left) next to the pipes which are above the combustion chamber, using the supplied brush. Once you have cleaned, re-fit the 4 flue deflectors. After having removed the ash drawer, extract the underlying base.
  • Page 25 Do not force the flue gas intake device flaps with the ash vacuum hose. Use a suitable suction device to remove the internal deposits and then re-position the base and the ash drawer. For correct functioning, it is necessary to use a suction device to remove the sawdust deposit on the base of the tank at least every 15 days.

  • Page 26: Cleaning The Ceramic Glass

    Cleaning the ceramic glass Always clean the glass when the boiler is off and completely cold. Use a damp cloth and specific detergent for ceramic glasses. Do not use abrasive sponges. Cleaning the flue This operation must be performed at least twice a year, at the beginning and half way through the winter season, and however when necessary.
