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 doing
installation, 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
INSTALLATION (for the installer)

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
Warning !

•Gas Supply Conne tion
-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 gas
circuit by using leak finder spray or non-corrosive foams

•Che king Gas Pressure and Nominal Heat Input (Fig. 2)
At the first installation, specialized technician must control Gas Economic Table Low nominal
heat input, maintenance, and gas conversion DO NOT improve Gas Economic Table Low
performance and increase nominal heat affirmed by the manufacturer Control heat input by
using 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 3, ± 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 minimum
resolution 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
