sure you have the correct cooktop for the type of gas being used.
• The pressure regulator must be connected in series with the manifold of the cooktop and must remain
in series with the supply line regardless of type of gas being used.
• The natural gas model is designed to operate at 4” water column pressure. A regulator is required at the
natural gas source to provide a mini- mum of 4” water column to the cooktop regulator
• The liquid propane model is designed to operate at 10” water column pressure. A regulator is required
at the LP source to provide a minimum of 10” water column to the cooktop regulator. For easy of
installation, and if local codes permit, the gas supply line into the cooktop should be 1/2” or 3/4” ID
flexible metal appliance connector, three to five feet long.

How to Keep Your Gas hob in Shape
Before cleaning or performing maintenance on your gas hob, disconnect it from the electrical power
supply (included battery power).
To extend the lifespan of the gas hob, it is absolutely indispensable that it is cleaned carefully,
thoroughly and usually, please keep in mind to the following:
⚫The enameled parts and the glass top, must be washed with warm water without using abrasive
powders or corrosive substances which could ruin them;
⚫The removable parts of the burners should be washed usually with warm water and soap, make sure
to remove caked-on substances;
⚫Automatic igniter pin, the end must be cleaned carefully and usually, make sure ignition keep
working normally.
⚫Stainless steel top plate and other steel parts can be stained if keep touch with high concentration
calcareous water or corrosive detergents (containing phosphorus). To extend the lifespan, we advise

12
these parts be rinsed thoroughly with water and dry them by blowing, It is a good idea to clean up
any spills too.
⚫After glass hob working, the surface must be cleaned by a damp cloth to remove dust or food
residues. Glass surface should be cleaned regularly with warm water and non-corrosive detergent.
First, to remove all food residues or greases with a cleaning scraper, e.g.
Cleaning scraper (not supplied).
While the cooking surface is warm, clean it with a suitable cleaning product and paper towels, then
rub with a damp cloth and dry surface. Such as aluminum foil, plastic items, objects made of synthetic
material, sugar or foods with a high sugar content that have been melted onto the surface, it must
be removed immediately.
While the cooking surface is still hot, clean it with a scraper and a transparent protective film which
prevent to make more dirt. This also protect the surface from damage caused by food with a high
sugar content.
Do not use abrasive sponges or cleaning products, these holds true for chemically aggressive cleaners,
like oven sprays and stain removers;
⚫Cleaning the grill/pan support, it is recommended to clean it while it is still hot. To move grill away
from the hob and put it in sink, remove the food residues or grease first, after grill has cooled, rinse
it with water.
Greasing the Gas Valves
Over time, the gas valves may be sticked, and it is difficult to turn on/off. For this case,
stop to use the gas cooktop and call a technician authorized by the manufacturer to repair.

between pan and pan support as serious damage to the
appliance may result.
Do not remove the pan support and enclose the burner with
a wok stand as this will concentrate and deflect heat onto
the hotplate.
Do not use large pots or heavy weights which can bend the
pan support or deflect flame onto the hotplate.
Locate pan centrally over the burner so that it is stable and
does not overhang the appliance.
Use only a wok support supplied or recommended by the
manufacturer of the appliance.

Valve & Flame adjustment
Valve adjustment
Valve adjustment should be done with the control knob set at Burner ON saving flame position.
Remove the knob, and adjust the flame with a tiny screwdriver (see below).
To remove the knob to adjust the flame To remove the knob and panel to adjust the flame
To check the adjusted flame: heat the burner at full open position for 10 minutes. Then turn the knob
into the saving setting. The flame should not extinguish nor move to the nozzle. If it extinguishes or moves
to the nozzle, readjust the valves.
Flame selection
As the burners are adjusted correctly, the flame should be light blue, and the inner flame should be clear.
The size of flame depends on the position of the related control knob.
-Burner ON, large flame -Burner ON, small flame（saving mode） -Burner OFF
See above for various operating options (flame size selection); the burner should be set at a large flame
during the initial phase of cooking, it makes food boil quickly. Then should turn knob to the saving flame
position to maintain the cooking. It is possible to adjust the flame size stepless.
It is prohibited to adjust the flame between the Burner OFF and Burner ON large flame positions.
High quantity of energy can be conserved if the hob is used correctly, parameters are designed correctly,
and appropriate cookware is used.
It is a prerequisite for efficient and energy-saving operation of hob that the burners are kept clean at all
times (in particular the flame slots and nozzles).
