Install burner firmly. Vibration may damage burner or its components. Keep boiler doors closed while starting burner and during burner operation. During the first commissioning of the burner or in case of any revision carried out in the electrical system or motor cables by any reason, direction of the fan rotation must certainly be checked by the authorized technical service.
2. TERMS OF WARRANTY Main and auxiliary equipment and all components used in Ecostar Dual Fuel (Gas-Heavy Oil) process burners are guaranteed for 1 year by TERMO ISI SİST. A.Ş starting from the date of commissioning under the maintenance, adjustment, operating conditions and relevant mechanic, chemical and thermal effects explained herein.
3. BURNER’S GENERAL FEATURES ECOSTAR Dual Fuel (Gas-Heavy Oil) burners are designed and manufactured to work with liquid fuel with max. 2.5- 20 Cst (mm s) viscosity. and Natural Gas / Liquid Petroleum Gas at gas pressures of min.20 mbar, max.300 mbar and at -%15 to +%10 of nominal voltages, under environmental temperature of max.60˚C with rated capacity and burner pressure ranges.

Consider the below torque values for bolts tightened on the valve. Tighten flange bolts according to cross ordering and use proper tools. Sealing and function check must be performed if the valve is dismantled and re-installed over the line due to any reason. Before dismantling the valve from the line, you can perform filter replacement according to the below order.

2 – If disc mechanism start positions are correct, start the burner and ensure that it activates in basic load. Detect min capacity activation fuel amount of the burner by checking min. return pressure. If the activation fuel amount is insufficient, set fuel regulator start adjustment to 9 or 8 value by changing spring adjustment from adjusting bolt on fuel disc number 2.When you start the burner again after this operation, you will see that your fuel return pressure has increased and hence activation fuel amount has risen.

8. MAINTENANCE 8.1. Weekly Maintenance Weekly maintenance is a routine cleaning and adjustment procedure which is performed to ensure smooth and continuous operation of the system. Burner components must be adjusted after each maintenance work in accordance with the instructions. Otherwise, the burner cannot be operated efficiently.
8.3. Seasonal Maintenance Comprehensive maintenance work when the burner is restarted after long periods of shut-down or interruptions. After completion of maintenance and adjustment processes, make sure to perform a combustion analysis. Ø Check insulation resistance of electric motor. Ø Make surface cleaning of ignition electrodes and porcelains. Replace cracked or broken porcelains.
9. TROUBLESHOOTING Problem Cause Explanation-Suggestion Heavy Oil or Gas valve might be closed. Open Heavy Oil or Gas is the valve. cut or does not come Check burner power supply. The fuse on the Fuse failure main panel or the fuse on the burner might be tripped.
