INTRODUCTION The PelTec / PelTec-lambda has a modern construction and design and is made out of the controlled materials of high quality, welded with most modern technology and is approved and tested under EN 303 - 5 norm and fulfil all special request for the connection on the installation of a central heating system.

  • Page 6: Status Of Delivery

    Status of delivery 1.4. STATUS OF DELIVERY Equipment is delivered seperately: 1. Boiler with planking and thermal insulation 2. Pellet tank in a cardboard box (the parts need to be mounted, see instructions for mounting the pellet tank) 3. Feeder screw with a flexible PVC tube (should be placed in the pellet tank) 4.

  • Page 7: Mounting Parts

    Mounting parts 1.5. MOUNTING COMPONENTS For ease of handling, transport and import of boiler, PelTec / PelTec-lambda is delivered in parts that need be mounted on the boiler when the boiler is in the boiler room. These parts need to be installed on the boiler: - mount on the back of boiler, is obligatory to use the flange gaskets fan, fastened using M8 bolts and nuts.

  • Page 8: Pump Group

    Positions of mounted components Pump group - mount pump group with 4-way mixing valve to the boiler so that the T-piece is in the upper side. On the upper connector of the T-piece incorporate safety ventilation group. On the back of boiler were prepared two holenders for mounting connection tubes (connection tubes with 4- way mixing valve).

  • Page 9: Pellet Tank

    Positions of mounted components Pellet level in the tank sensor - mount this sensor on the back side inside of the pellet tank. First set the plastic glass distance for sensor. After that, put the sensor on this glass. Attach the sensor and the plastic distance with 4 screws supplied.

Remove the two screws (C) and just slightly loosen screws (D) as shown in picture below . Carefully attach grate cleaning mechanism to loose screws (D), then fasten with screws (C) and tighten the screws (D).
  • Page 11 Grate cleaning 3. Set the screw (E) into the jagged track (F), set the nut on the screw and tighten. Free space (G) is required for the proper functioning of the mechanism. 4. Connect the connectors (H) so they have a good contact. Carefully set the cover and tighten with the screws (A).
  • Page 12 Setting photocell on the work position 1.5.3 SETTING PHOTOCELL TO THE WORK POSITION Before first startup, be sure to set the photocell to the position as on Figure 3, otherwise the boiler will not work properly! The photocell should not be set too deep or too shallow in the box. So, limiter determines the proper depth of photocell position.

  • Page 13: Safety Elements

    Safety elements, fuel 1.6. SAFETY ELEMENTS Boiler have a few safety elements: - Bimetal thermostat built on the burner pellet feeding tube. If the bimetal set temperature (80°C) is exceeded, pellet feeding is stopped, the burner shuts down and the error E3 appears on the control unit (LED diode switches on).

  • Page 14: Boiler Positioning

    Boiler positioning 2.0. BOILER POSITIONING AND ASSEMBLY Boiler positioning, assembly and building in must be performed by a qualified person. We recommend that boiler is placed on a concrete base with height of 50 to 100 mm above the floor. Boiler room must be frost- proof and well ventilated.

  • Page 15: Connection To The Chimney

    Connection to the chimney 3.0. CONNECTION TO THE CHIMNEY IProperly dimensioned and built chimney is the main condition for safe and economical functioning of the boiler. The thermal insulation of the chimney has to be done properly, it has to be absolutely gas-proof and smooth. On its lower part there has to be built in the opening for cleaning with the door.
