Activities: 

10.1  General inspection 

  Check the overall condition of the installation. Check the heater, the thermostat, the wires 

and the gas line. 

 

10.2  Inspection of the heater 

Before starting the inspection, switch off the electric power to the heater with the maintenance-

switch and close the manual gasvalve. 

  Take out the burner, complete with flange and pre-mix fan, by unscrewing the 6 off M6 

socket screws and you have taken off the ignition and fan wires 

   Check the heatexchanger from the inside for dirt and/or damage. 

  Check the burner on damage and clean the ignition electrode if necessary . CAUTION: do 

not twist the electrode out of shape! 

   Check the airsupply and the flue discharge. 

  Clean eventual the inside of the heater with a vacuum cleaner. 

  In case the heatexchanger is  dirty on the outside, clean it with a soft brush. Never use a 

steel wire brush! 

  Clean the fan-grid with a vacuum cleaner and a brush.  

   Put the burner back in (renew the gasket) 

 

After this, check the heater on efficiency of combustion and adjust these if necessary 

Check the heater operates correctly.
