  • Page 7 ÷ = must not be used Usage of other and less suitable fuel types for MULTI-HEAT - over and above the wood pellets indicated above, grain (wheat and barley), corn (maize) as well as wood chips can result in less problem-free operation, more work for the user and possibly a greater fuel consumption.

    1.1.3 Service and guarantees: The guarantee is described more closely in the BAXI Guarantee Certificate which is delivered together with the boiler. Complaints: You ought always refer to the fitter or dealer who has installed / delivered the central heating boiler for you.

    It is the responsibility of the owner or user that the boiler and equipment, if any, are cleaned and maintained in accordance with: normal practice indications in this instruction instructions for equipment / accessories, if any as well as conditions described in the appurtenant guarantee certificate (See section 1.18 Preventive maintenance as well as the boiler's guarantee certificate).

  • Page 13 Fixed low output light above button and light on row 30-100% The greatest advantage can be achieved by choosing the form of operation called 2- step operation.. 2-step operation: Here, the boiler must run at a high output until the temperature is just 3 degrees below the desired temperature, and then switched down to a low output.
  • Page 14 The lowest button is used to set the number of seconds between each worm conveyor/ auger delivery - this can be set between 10 and 60 seconds, but never below the setting of the high output. The setting is shown in the display. Press in and hold "SEC" and adjust up or down by means of pressing on + or –.
  • Page 15 (F) Alarm re-set- Here, the alarm is re-set. If there is no alarm, use the button to come into the set-up menu (but simultaneously with the (C)-button). The following are the alarms which can appear: There is no fire! The smoke temperature has been below 100°C during operation for more than 30 minutes of operation, or after intermittent firing and starting up.
  • Page 16 (LX.X) Here, the worm conveyor/auger's adjustment time is adjusted at "low output" - i.e. the time which the worm conveyor/auger is running each time. Adjustment area: 0.1-6.0, corresponding to 0.1-6.0 seconds. Factory setting:: MULTI-HEAT HX.X LX.X Type (high output) (low output) H1,7 = 1,7 sec.

    Factory setting (P05) = 5 seconds The settings can be changed by pressing on + or minus on REG (R). By means of the operation form button (C), the desired setting can be saved, and it is possible to "step" further in the menu. Step through the program with the menu button (B).

  • Page 18: Ignition

    Prior to starting up the boiler, it is necessary to ensure that the water supply is connected to the retrograde combustion (back burn) valve. (See section 1.16 - retrograde combustion (back burn) valve). It is necessary to ensure that the ignition/fuel arc (pos. 9, fig. 1.1) is pushed right back. The hopper lid must be closed, since this hinders retrograde combustion (back burn).

    80-160 W/m2 and in a more modern house, approx. 50 W/m After this, set at low output - see technical data and use the recommended adjustment data from the PC- diskette from BAXI A/S. The colour of the flame ought to be yellow and slightly bluish.

  • Page 20: User Experiences

    If the flame is short and blue, either the interval time or the air quantity must be reduced. If the flame is long and reddish-yellow, either the interval time or the air quantity must be reduced. Colour of the flue gas If the flue gas is black or dark-coloured, this is because the combustion is getting insufficient air.

    4. Cleaning the fire tubes On MULTI-HEAT 1.5 and 4.0, turn the smoke gas turbolators approx. 15 times so that the ash particles are sucked backwards into the smoke box.

  • Page 24: Operating The Pump

    5. Removing cinders Removing cinders from the boilers combustion chamber takes place as required. This requirement is dependent on the ash contents of the fuel. 6. Cleaning the vent pipe While cleaning the vent pipe from the boiler to the chimney, it is important NB: the smoke gas sensor is that the smoke gas sensor is meanwhile removed so that is does not get bent removed.

    The regulator for the weather compensation system can be mounted in the boiler control system on MULTI-HEAT 2.5 and 4.0 (but not on MULTI-HEAT 1.5). Electrical connection is traditionally carried out without a Multi-plug, by means of the bottom-side's terminal strips.

    Please consult your chimney sweep before building in a draft stabiliser. A draft stabiliser can be bought from BAXI as an accessory (see figure below – secure draft stabiliser in appropriate material with external bearings with good accuracy of adjustment).

  • Page 34 NB: Before the electrician tests the running direction of the worm conveyor/auger, it must be ensured that all pieces of wood and/or iron, if any, have been removed from the hopper, which otherwise could prevent the worm conveyor/auger from rotating. Electrical test of the running direction of the worm conveyor/auger: Close the lid over the hopper and open the lowest cleaning door.
