6.2.2
Working principles for devices made of "stainless steel"
•
The surface of the device made out of stainless steel has to be clean and accessible for air. If
the device is not in use, please open the door, so the air is able to circulate.
•
Clean the device regularly, and remove lime-, fat- and protein layers. It is possible that under
these layers, corrosions can be formed, cause by missing access of oxygen. When you clean
the device, you should not use bleach and chloride-containing cleaning agents. Please use
cleaning agents with low chloride. After cleaning the device, remove all residues of the cleaning
agents using fresh water. Afterwards, you have to dry the surface thoroughly.
•
Do not let any parts of stainless steel get in contact with concentrated acids, spices, and salt
any longer than necessary. In addition, acid fumes, which form during tile cleaning, enhance the
corrosion of "stainless steel”.
•
Prevent damaging the stainless steel, in particular by other metals. Foreign metal forms tiny
chemical elements, which cause corrosion. In any case you should avoid contact of metal and
steel, that leads to external rust. If stainless steel comes into contact with iron (steel wool, chips
from pipes, ferrous water), The corrosion can be triggered Therefore, use only stainless-steel
wool or brushes made of natural, plastic or stainless-steel bristles for mechanical cleaning. Steel
wool or brushes with unalloyed steel lead to external rust caused by abrasion. Fresh rust spots
can be removed with mild-acting abrasives or fine, unused sandpaper.
6.3 Maintenance of gas technical parts
The device has to be regularly checked by an approved technician for proper function.
We recommend a semi-annually maintenance interval.
After new re-adjusting, maintenance or after a disassembly, the device has to be checked for
proper function.
Any occurring malfunctions must be remedied immediately. The regulations of local statutory or-
ders, the local laws valid for your countries, technical regulations for LPG and the directions of
the local gas supply company have to be observed.
In particular, the following things have to be checked.
•
function of the existing control and safety devices
•
checked the igniting behaviour according to ignition behaviour and burning safety (If nozzles
are narrowed or blocked by dirt, these must be cleaned or replaced)
•
tight fit of the burners
•
control of function (4.4.4)
•
Regular leak testing of all gas-carrying parts.
For maintenance, please observe especially the following points:
6.3.1 Burner
For burner maintenance check the following points and eliminate the faults.
•
Check the general condition with regard to fixings, damages.
•
Fixing of burner nozzle assembly.
•
Burner outlets: are the nozzles blocked by waste or anything else they have to be cleaned in
any case.
•
Check the primary air area with regard to any waste.
•
Check the function of ignition safety.
