  • Page 8: Technical Data Cb Boilers

    3 TECHNICAL DATA CB BOILERS 3.1 Functional introduction The CB boilers are central heating boilers with a maximum high efficiency. Such a performance can be reached by, amongst other things, using a special heat exchanger made of stainless steel. This allows the flue gases to cool down below the condensation point, and so release extra heat.

    The boiler must be positioned and installed by a skilled installer in accordance with all applicable standards and regulations. Commissioning of the boiler must be done by a skilled service/commissioning engineer, who is trained for this type of boiler. 6.3 Mounting the boiler Before mounting and installing the boiler the following connections must be considered: •...

    The condensate trap must al- ways be filled to the edge with water, before replacing to the unit. 7.3 Flow and return connections Use T-pieces for externally mounting the pres- sure relief valve and the boiler bleed valve for BOILER servicing the boiler.

  • Page 20: Bypass

    7.7 Bypass The boiler has no internal bypass. When many thermostatic valves are being used, the system must have a by- pass to allow an adequate flow when all thermostatic valves are closed. Instead of a bypass also a low-loss header can be used for this function.

    Maximum glycol concentration is 50%, read the suppliers instruction carefully. Because of the higher viscosity of the glycol mixture, increase pump head by 20% at 40% glycol. For use with glycol, select a pump with glycol seals. Because of the lower heat capacity of the glycol mixture, power will be reduced by approximately 10% at 40% glycol.

  • Page 87: Temperature Protection

    13 TEMPERATURE PROTECTION The difference between Supply temperature and Return Temperature is continuously monitored. A too big differ- ence can indicate a defective pump or a clogged heat exchanger. To protect the boiler, the burner controller re- duces the input when the temperature difference ΔT becomes too high: At maximum boiler input ΔT is limited to 35°C (63 °F) - (Hx_Diff_DeltaT_Min ) In between 35°C (63 °F) and 43 °C (77 °F) boiler input modulates between minimum and maxi- mum.

    14 ERROR INFORMATION. Errors can be divided in three groups: • Manual reset locking errors (can only be reset by the reset button). • Blocking errors (will disappear when error is gone) • Warnings (will disappear when the warning is gone, not stored in the BCU) The boiler pump will continue to run during most locking and blocking error codes.

    The managing boiler of the cascade system is connected to the AL-BUS connection on terminals 20-21 This connection also provides the power for the communication bus. The depending boilers are all parallel con- nected to the managing boiler communication bus. The bus power is provided by the managing boiler on terminals 20-21, switch S1 must be set in the OFF position (all controls).

  • Page 97: Cascade - Heating Only Managing Boiler

    15.3.3 C – H ASCADE EATING ONLY ANAGING BOILER When a boiler is set as "Managing" (parameter 184: "Burner address"), the controller of this boiler will drive the cascade. The CH mode of this managing boiler applies to all other boilers. It is only required to set the CH mode on the managing boiler.

  • Page 98: Cascade - Boiler Rotation

    15.3.6 C – B ASCADE OILER ROTATION The boiler rotation function can change the start/stop sequence for the cascade boilers. The parameter Boiler_Rotation_Interval sets the number of days after which the sequence is updated. When Boiler_Rotation_Interval is set to 0 boiler rotation is disabled. When the parameter Burner_Rotation_Interval is updated the boiler rotation days left will be initialized to the new Burner_Rotation_Interval setting.

  • Page 99: Emergency Mode

    15.4.2 E MERGENCY MODE Managing boiler error When the managing boiler is in error mode, the depending boilers can go into the "Emergency_Mode", if enabled. In emergency mode the system setpoint is set to the temperature of the Emergency_Setpoint and all cascaded boilers start burning on this setpoint.

  • Page 101: Commissioning The Boiler

    17 COMMISSIONING THE BOILER 17.1 First: flushing the boiler with water After installation of the boiler the first step, before commissioning, is to flush the boiler and the whole heating installation with fresh water to remove pollution, debris and other materials that might cause a blocking. This must also be done with heating installations, where only the boiler is replaced.

  • Page 102: Mounting Condensate Trap

    17.4 Mounting Condensate Trap When mounting the bottom part of the condensate trap, before commissioning the boiler and/or after maintenance, it must ALWAYS be completely filled with water. This is a safety measure: the water in the condensate trap keeps the flue gases from leaking out of the heat exchanger via the condensate drain.

  • Page 103: Adjusting And Setting The Boiler

    18 ADJUSTING AND SETTING THE BOILER Before carrying out any adjusting of the burner, carefully read this complete chapter. The initial lighting of the appliance must be performed by a licensed Gas Technician. Fail- ure to follow these instructions may result in property damage, serious injury or death. As soon as the appliance has been fully installed (with regard to hydraulics, filling and de- WARNING aeration of installation, gas, flue gas, air intake, wiring etc.) according to the preliminary...

    19 INSPECTION, MAINTENANCE AND SERVICE. 19.1 General For a good, safe and long-time operation of the boiler and to maintain warranty it is mandatory to carry out in- spection, maintenance and service on the boiler at least once a year and/or after 2000 burning hours maximum, whichever comes first.
  • Page 111 Water leakage The water pressure of the heating installation must be more than 1.0 bar (21 psi) and at a maximum of 6.0 bar (87 psi) in normal operation. When the water pressure drops below the minimum occasionally, there might be a water leak.
  • Page 112 Burner Check the burner surface to see if it has damages, signs of rust and/or cracks. When the burner surface is dam- aged the burner must be replaced. The burner can be cleaned by using a soft (non-metallic) brush. The dust can be removed with a vacuum cleaner or pressurized air.
  • Page 113 Fiber braid replacement If the high temp braided rope is damaged and needs to be changed, it has to be replaced by new braids using the method described below. The high temp braided rope is maintained by silicone glue. - Remove electrodes. - Remove the braids by sliding under the periphery a thin tool to loosen the braids and remove it.
  • Page 114 Insulation The insulation of the heat exchanger (located on the rear wall inside the heat exchanger and burner door) must be inspected. If this insulation disc shows any signs of (water) damage or degradation it must be exchanged. Also check if there are any indications in the burner room of a high condensate level (caused by a blocked condensate trap) that might have wetted the rear wall insulation.
  • Page 115 Install the new insulation: - put two dots of glue silicone, temperature-resistant (Loctite 5366 or Ot- toseal S17), according to the location indicated. - make sure that the burner is in proper condition, remove any possible insulation residues on the burner - put a plastic protection skirt around the burner to protect the insulation from the burner.

  • Page 116: Mounting The Burner Door

    Gas/air ratio With every service check and/or maintenance of the boiler always check the gas/air ratio by measuring the CO percentage (flue gas) at the maximum and minimum load of the boiler. If necessary, adjust these values. See for information chapter “Adjusting and setting the boiler” chapter 18. Pump (supplied separated from the boiler) Check the electrical parts and the motor of the pump for a correct functioning.

  • Page 117: Maintenance Checklist

    19.3 Maintenance Checklist Allowing the boiler to operate with a dirty combustion chamber will hurt operation.
