Maintenance

 CAUTION

To ensure that no damage occurs during operation 

and maintenance, please observe the following 
instructions. Otherwise, injuries or damage to the 
device may occur and/or the function of the device 
may be impaired. The supplier/manufacturer cannot 
accept liability for damage resulting thereof.

–   Have the heater cleaned at least once a year 

by qualified maintenance personnel.

–   Have the safety functions checked at least once 

a year by qualified maintenance personnel, see 
page 19 (Checking the safety functions and 
burner operation).

–   Check the chimney once a year with your local 

chimney sweep to find whether the flue gas and 
air supply routes are clear.

–   Sharp-edged metal sheets. Always wear protec-

tive gloves.

–   After cleaning or repair work, check that the 

components on and in the heater are in good 
condition. The device may only be restarted 
if all safety devices have been installed and 
the safety functions have been checked, see 
page 19 (Checking the safety functions and 
burner operation).

  

 Switch off the burner control unit.

Visual inspection
  

  Check all heaters for dirt and clean them accord-

ingly, see page 11 (Cleaning).

  

 Check all heaters for damage and loose parts.

 4 

 The rubber seals between the electrodes and 

electrode plugs may be displaced by the water 
jet. Check whether the seals are fitted correctly.

 5 

 Check the wiring.

 6 

 Check the cable glands.

 7 

 Depending on the number of operating cycles, 

we recommend that the ignition electrode and 
ionization electrode are replaced once per year.

 8 

  Check the seal on the housing cover of the burner 

control unit. Replace it if necessary.

 9 

  Check the inside of the housing cover for traces 

of dust, dirt or moisture. If you find such traces, 
the cause must be rectified at all times, e.g. by 
sealing an open cable gland.

 0 

 Check the cable harness and wiring for signs of 

damage.

Number of operating cycles
  

 Check the number of operating cycles (heat-

er ON): the number of operating cycles can be 
displayed by pressing and holding the RESET 
button. The number of operating cycles is com-
posed as follows in alternating displays:

 

 The first character (X.) stands for X,000,000 op-

erating cycles, the second character (Y) stands 
for Y00,000 operating cycles. For example, the 

first character is the number 2: the unit has ex-
ceeded 2,000,000 operating cycles.  The second 
character is the number 3: the unit has exceeded 
300,000 operating cycles. The total number of 

operating cycles is composed of the numbers 
2 and 3. This gives a total number of operating 
cycles of 2,300,000.

  

  Disconnect the system from the electrical power 

supply.

 

The heater may only be disconnected from the 

electrical power supply once the device has been 
switched off and post-cooling is complete.

 4 

 Shut off the gas supply.

Checking the safety functions and 
burner operation

 WARNING

Risk of explosion!

–   If these checks are not carried out, the gas 

valves might remain open allowing non-com-

busted gas to escape.
