3-5. Cleaning and maintenance
After installation, the installer should remind the user to pay attention to the following matters in cleaning and
maintenance:
Cooktop cleaning and maintenance
Fire cover cleaning and maintenance
Recommended maintenance
frequency
Before cleaning the gas cooker, the indoor gas valve must be
cut off and the gas cooker has cooled. Do not disassemble the
safety devices and airtight parts of gas cookers during the
cleaning process;
Do not use acidic materials (lemonade, vinegar, etc.) to scrub
enamel surfaces (eg, holder rack, etc.);
Please use soft gauze and soapy water (or stainless steel
special cleaning agent) to clean and maintain the cooker board;
Do not clean the board with a granular detergent (scrub
powder) or steel wool. This can cause scratches on the surface
of the cooker.
For long-term use, there will be oil pollution inside the fire
cover. As shown in the figure on the left, the fire cover can be
disassembled without any tools, and the oil inside the fire cover
can be cleaned easily and simply;
When dismantling or installing the fire cover, avoid hard
objects from colliding with the ignition needle to prevent the
needle from being damaged and affecting the use of the cooker.
After cleaning and maintenance, place the fire cover in place
(for details, see 3-4 "Inspection of parts in place");
In the use process, if you find that the flame is uneven or there is
no flame in the individual fire holes, after the fire cover cools, remove
the fire cover in time and clean the dirt and carbon deposit in the fire
hole with iron brush and steel needle. Do not wipe the inorganic
water-resistant coating on the burner surface with a hard object. This
will cause damage to the black surface that cannot be repaired;
Wipe the discharge end of the ignition needle in time to
prevent the dirt from attaching to the surface and affecting the
ignition performance.
