Very important!: Before installing, place the appliance on solid, flat, stable and horizontal surface and connection
availability.
The following instructions are intended for authorized and qualified installer. Before doinginstallation,
adjustment, and maintenance operations, the installer must follow local and legal regulations. Cut the
electrical power before doing any installation.
1. This appliance is using gas. Gas services should be installed according to:
a. Local and international standards
b. Local recommendation, such as building standards and recommendation concern with
combustion
c. Directions and regulations from the gas and power supply companies
d. Regulation concern with prevention accident measures
2. Remove all packaging material and protective coatings.
3. Ensure gas supply is sufficient to operate this appliance.
4. Install the appliance by using Qualified Gas Filter.
5. Before testing, put the appliance in a good ventilated room and keep all flammable material away.
6. Take a leakage test by using soapy water solution. Spread the soapy solution on joints and pipe fitting. A
leakage will be indicated by bubbles comes from the joints or pipefitting. Another way is by looking at the
gas counter. If there is no movement on the gas counter, it means no gas leakage.
7. Before cleaning or maintaining the appliance, please isolate gas supply to the safe place.
8. Install the appliance by following Safe International Gas Standards.

9. If the appliance has not preset to the gas availability, you must convert it into another gas type.
Authorized personnel must do this by referring to the technical data (primary air regulation and nozzle table),
changing the main burner and pilot burner nozzles. Once this has been done, a new rating data plate
should be affixed to the new data by referring to the new gas type.
• Position and Fixing
Authorized personnel must do the installation. Install the appliance according to National Safety
Standard about gas-heated standard. Place the appliance in good ventilated room with permanent
ventilation ducts to guarantee sufficient exchange of air and keep the work place healthy. If the Gas
Economic Table Low not connected to a flue, it is recommended to install it under efficient hood, which could
evacuate burned gases and cooking steams. Make sure that any object around or under Gas Economic
Table Low does not obstruct air volume required for combustion. Put away any flammable materials near
Gas Economic Table Low. When the appliance is freestanding, keep a distance at least 20 cm from side,
and 10 cm from rear walls. Especially when the appliance close to wall and does not protected with fire-
resistant materials made. Install the appliance separately or side by side with other appliance according
to recommended range. Put Gas Economic Table Low on solid, flat, and horizontal floor. Adjust the
height of the four feet by using brackets. Before turn the appliance ON, remove the protective film.
Remove any adhesive with appropriate solvent. Eliminate all packaging material according to
national laws.

• Gas Supply Connection
- Before installing and connecting Gas Economic Table Low to gas supply, carefully control the
fixed part of gas system, which conformed to National Building Regulation.
- Verify gas pipes sections to guarantee sufficient supply for all gas heated appliances.
Install it in similar condition to avoid excessive pressure drops.
- The pipes must be made of steel (with junctions made using white cast iron, or
galvanized steel fittings, or autogenously welded joints) or copper pipes (with mechanical
joints and couplings without seals or mastics or brazed joints).
- Control the gas bottle (if any) placed correctly and protected in dry area.
- Check whether the gas pipes can easily inspected. If the pipes installed in floor and wall,
make sure that this work done according to professional standard with reference points
that make it possible to find the pipes.
- Before installing Gas Economic Table Low, makes sure that it is set for the gas and
pressure (see Technical Data Plates). Consult the paragraph “Gas Conversion”.
- Connect Gas Economic Table Low to gas supply using solid fittings or flexible steel pipes
with suitable sections related to nominal power and length.
- Check whether the flexible pipes does not pass or near hot surfaces, put under stress
and traction, contact with sharp edges, or other things that could damage the pipe.
- Install quick ON –OFF valve between the gas mains and each single appliance where
easy to reach.
- After install Gas Economic Table Low safely, take a pressure test the whole gascircuit
by using leak finder spray or non-corrosive foams.

• Checking Gas Pressure and Nominal Heat Input (Fig. 2)
At the first installation, specialized technician must control Gas Economic Table Low nominalheat
input, maintenance, and gas conversion. DO NOT improve Gas Economic Table Low performance
and increase nominal heat affirmed by the manufacturer. Control heat input byusing gas counter and
chronometer. Measure the exact amount of gas flow per unit of time which consumed by the appliance
at maximum power. Compare the measurement to the consumption data on Data Technical Table 8,
± 5% tolerance is allowed. When you are measuring top deviations, carefully check the diameters and
the quality of installed injectors and gas main pressure. If you want to measure the main pressure while
Gas Economic Table Low is ON and using a pressure gauge for liquids (for example U manometer,
with minimumresolution 0.1 mbar), please follow direction below:
1. Connect the flexible pipe “E” of the Manometer “M” to the inlet pressure point “C” after unscrewing
its cap.
2. Measure the connection pressure: if the reading is not within the values given in the following table,
the appliance cannot work properly. The gas company must be informed to find out the supply pressure
problems. If necessary, install a pressure regulator.
3. Once the connection pressure has been measured, disconnect flexible pipe “E”, retighten the screw
cap of the inlet pressure point “C”. Restore the components inversely.

• Adjusting Small Combustion ( Fig. 3)
The small combustion must be adjusted into 3,0 kW. To adjust the small combustion,
follow direction below:
a. Operate burner in small combustion.
b. Turn OFF the security control knob handle.
c. Adjust small combustion nozzle (9) for 3 kW (according to the table). Turn clockwise
to reduce warmth load, turn anticlockwise to increase warmth load. Adjust the
warmth load according to volume method.
d. Ignites properly.
To change small combustion nozzle (9) for Liquid gas / LPG Gas, turn slightly
against the stroke.

• Adjusting Pilot flame ( Fig. 4 and 5)
Adjust the Pilot flame by following direction below:
a. Remove screw cover (10) and washer (11).
b. Adjust nozzle (C) according to the table to make Main Burner ignite
properly. Turn the nozzle clockwise to reduce gas flow. Turn anticlockwise to
increase gas flow.
c. When operated with Liquid gas, turn nozzle (C) clockwise toward stroke.
After adjusting washer (11) and tightening cover screw (10).

WARNING! After doing conversion please remember to:
• Attach an indelible sticker on technical data plate with the new
installation data.
• Fix the new seals on the regulated parts (Primary Air Bush,
Injector, and By-pass screw).
• Take pressure test of gas circuit and check for leaks.
• Properly control Gas Economic Table Low work according
to these instructions.Please check main burners’ cross-
lighting, stability, and flame factor.

Before replacing any components, please:
- Turn OFF the appliance
- Cool the appliance
- Close the ON / OFF gas valve at UP position
Access the components after open the frontal panel and remove the cooking grid.
USE GENUINE SPARE PARTS ONLY!
• Changing Nozzle Burner (Fig. 8)

b. Pull the Burner from the mixing chamber (3).
c. Remove it with fixing screw (2) form the mixing chamber (This screw is
reachable from below).
d. Remove the complete mixing chamber (3) by turning anticlockwise from the nozzle.
e. Turn the pressure ring (4) from the nozzle. DO NOT LOSE THE PRESSURE RING !
f. Remove the nozzle from the nozzle carrier and replace the nozzle with the
new one according to the destined country and gas type.
g. Fix the nozzle by using non-hardening sealing tape.
