adjustment of the V-belt must be checked. The fan runner should be checked for dirt every 6
months and tightened up if necessary.

All other components in the WA 45 - 300 units are service-free. The burner should be checked
according to the instructions of the burner supplier. The function of all internal thermostats must be
checked once a year.
5. FAULT FINDING
In case of failure, check the following:
¾ Is there any gas at the burner?
¾ Is there any oil in the tank and are all valves open?
¾ Is the power supply to the unit OK?
¾ Is the room thermostat/seven days programme panel setting higher than the room
temperature?
¾ Are the air intake and air outlet openings free?
If the above points are OK, check the heater according to the table below.
