Replacing Important Components; Maintenance And Cleaning - Diamond G77/4F7T-N Handbuch

5.
The unit should be checked at least twice a year. You must check the burners, the ignition, the interignition, the maximum and
minimum settings.
REPLACING COMPONENTS
To be performed exclusively by an "Authorised Service Centre"!
In order to replace these components, it is important to first do the following:
- Shut off the gas supply inlet valve;
- Remove the knobs;
- Disassemble the front panel;
- Possibly remove the grills, the flame-spreaders and the burners.
Now you can replace the more important components.
A) Worktop burner thermocouple (Fig. 3)
- unscrew the nut (7) with a size-8 spanner
- unscrew the nut (Fig. 2 position 3) with a size-9 spanner
- install a new thermocouple of the same type, following the opposite assembling order.
B) Worktop burner cock (Fig. 2)
- unscrew the nut (3) with a size-9 spanner;
- disassemble all the gas connections (4-5-6);
- install the new cock following the reverse order of assembling;
- Pay attention to the bypass! Replace or invert the bypass idle screw.
N.B.: Check for gas leaks with bubble soap: sealing must be perfect.
C) Plate piezoelectric igniter
It is very easy to disassemble the igniter from the oven dashguard:
- detach the high-voltage wire;
- unscrew the nut with a size-25 spanner;
- install the new piezoelectric igniter, following the opposite assembling order.

- Clean the stainless steel parts daily with soapy lukewarm water, then rinse well and dry thoroughly.
- Absolutely avoid to clean the stainless steel with common steel-wool, or common steel brushes and scrapers, as they may
discard ferrous particles which, on depositing, cause rust spots. You may, if you like, use stainless steel-wool passed on
following the butter-finish direction.
- Should the unit remain unused for long periods, heavily rub all the steel surfaces with a cloth slightly wetted with vaseline
oil, in order to cover them with a protective film. Periodically ventilate the premises.
COOKING TOP
Frequently clean the plate by using a wet rag, then switch it on for a few minutes turning the knobs to top temperature in order
to dry it quickly. Finally, grease it with a thin film of vaseline oil.
IMPORTANT
After using detergents, rinse the plate and switch it on for a few seconds to let it dry. Periodically cover it with a film of oil or
similar product for protection. This way the plate will always be just as new.
STAINLESS STEEL PARTS
The stainless steel parts too must be cleaned with soapy water and then dried with a soft cloth.
The bright polish is kept by periodical wiping with liquid (POLISH), a product easily available.
