8. Maintenance
CAUTION
Do not use waterjets to clean the appliance!
To protect the BCU, an optional protective cover is available.
Inadequate cleaning can result in serious damage.
•
Regularly check the heater(s) and all fuel hoses for loose connections and leaks.
•
If you are using oil boxes, the bleed valve on the oil boxes must be opened regularly to allow any air
which may have collected in the fuel lines to escape.
•
If you use the heater seasonally, check that it is in good working order well before you need to use it,
so that you have time to deal with any unexpected problems.
•
Always disconnect the mains: Before carrying out maintenance work, always isolate the heater from
the mains electrical supply by removing the mains plug from the socket.
•
Periodically wipe the outside of the heater with a soft cloth. A small amount of a non-aggressive
cleaning liquid may be used, but the heater must be thoroughly dried afterwards.
•
Remove dust and dirt from the inside of the heater with compressed air. To do this you will need to
remove the safety grille from the back of the heater or the service cover on the side.
•
If the heater is being used in a very dusty environment e.g. a broiler house, the combustion head,
the photocell and the photocell housing should be cleaned after every crop. To do this, you will need
to remove the combustion head from the burner chamber by loosening the
two wing bolts (see diagram chapter 10). The combustion head can then
be withdrawn and cleaned (with compressed air). Make sure to clean
the four air inlets on the stabiliser. The photocell can be cleaned
with a dry cloth. Compressed air should then be blown through the
photocell housing. When replacing the photocell in its holder,
remember that it has to be oriented so that the pipe on the photocell
clicks into the matching recess on the holder.
•
Clean the oil filter on the pump when dirty. Do not forget the rubber O-ring when reassembling the
filter. (Tighten the filter jar well!)
•
After carrying out maintenance work, make sure that all components you have removed from the
heater are correctly replaced.
•
If you think that the heater or its combustion system is not working properly, consult an approved
engineer. Approved engineers have special equipment with which they can check the heater
thoroughly.
