You must definitely ensure sealing between boiler and burner!

Device must be shipped in original packaging!

Do not lift the device holding from servomotor, gas valve, impulse pipes or pressure switch
during installation!

Clean the inside of fuel line thoroughly before installing the burner to the fuel line. Any
damage that may occur due to solid objects and metal particles from the fuel line shall not be
covered by our company.

13.06.2017 Rev. 01 12

While installing the burner in reverse flame front mirror boilers, flame tube tip must be adjusted
such that it gets inside by 50 mm-100 mm from flue pipes (50mm≤A≤100mm). Otherwise flue gas
temperature will rise and fuel consumption will increase.

COMMISSIONING

Before Commissioning

Electrical connection

Perform electrical connections according to the diagram provided with the burner. Follow general
security rules during installation of electric wiring and making connections. Connect the earthing terminal
in electric panel to the earthing installation.

General Controls

Make sure to perform the following controls before commissioning the burner.

Ø Are the electrical connections correct?

Ø Is there electricity current?

Ø Is there gas?

Ø Has the heating system been filled with water?

Ø Is the thermostat set at the required temperature?

Ø Has the boiler explosion lid been controlled?

Ø Is there sufficient air in boiler room (ventilation section cm² = boiler capacity kW x 7)

Ø Has the boiler been installed correctly? Has the boiler cover been closed properly?

Ø Has the air of the gas line been removed? Has a sealing test been made?

13.06.2017 Rev. 01 13

Operation of a modulating burner

Ø Open the main gas valve; check max 300 mbar gas pressure from the manometer.

Ø Open operating switch on the burner panel.

Ø Switch on the modulating control switch.

Ø Switch automatic-hand switch to automatic.

Ø Check the temperature and pressure set values from the modulating control unit.

Ø Ignition will take place at the end of pre-purge process.

Ø 3 sec. later, the gas valve will be opened and combustion will occur.

Ø Flame control system (ionization) will start flame control.

Ø In modulating burner, the burner goes into max. capacity according to the signal from the

modulating control unit.

Ø When the boiler water temperature or steam pressure increase, the modulating control unit will

cause burner to run with min. capacity.

Ø If the boiler water temperature or steam pressure increases despite the operation of burner with

min. capacity, the modulating control unit will stop the burner.

Combustion Adjustment

Gas Adjustment

Follow the instructions of the valve manufacturer during installation, dismantling and adjustment of the
gas valve

VGD 40… Series Gas Valve

13.06.2017 Rev. 01 14

Air pressure switch adjustment

While the burner is working without any problem, the air pressure switch
is adjusted to desired minimum pressure as follows.

Ø Unscrew the screw of the transparent cover and remove the cover.
Ø Turn the adjustment wheel in the direction to increase the pressure,

note the pressure value at which the burner is failed.

Ø Set the pressure switch to a value 1 mbar lower than the pressure

value at which the burner failed and close the pressure switch lid.

Ø It is recommended that this adjustment is carried out when the

burner is at minimum load.

Leakage Test for Main Gas Valves

13.06.2017 Rev. 01 17

Servomotors

Servomotors drive air dampers, gas butterfly valve and oil regulator. With the help of servomotors
electronic air and fuel ratio control is carried out, controlled by burner control.

Ø Static electricity can damage servomotor.
Ø Do not open servomotor. Do not interfere with or modify unit or equipment connected to it. It may

damage servomotor or change burner settings.

Ø Completely isolate equipment from the main supply before performing any wiring changes in

servomotor connection area.

Ø Check that wiring is in an orderly state.
Ø Protect equipment from condensation, water and ice.
Ø Fall or shock can adversely affect safety functions. Such servomotors may not be put into

operation.

Do not open servomotor. Do not interfere with. It may damage servomotor or change burner

settings.

13.06.2017 Rev. 01 18

Function Controls and Adjustments

The BT300 combines the benefits of an electronic fuel-air ratio control system with up to three
motorized actuating devices and an optional module like an analogue output for speed control of the
combustion air fan with an electronic burner control unit. The leakage test, flame monitoring system,
power control unit and (optional) CO/O2 controller for control and optimization of an oil or gas-fired
forced-draught burner are all integrated. The BT300 is suitable for virtually all combustion plants. Safety
interlock chains, monitors (e.g. gas and air pressure) and sensors are wired directly to the BT300. This
greatly reduces the cost of additional relays and wiring. The BT300 was designed to be attached to the
burner. The short wiring paths also save money. As a result, the BT300 is particularly suitable as standard
equipment for monoblock burners. The compact design of the BT300 burner control system also has its
advantages during commissioning. Standardizing the wiring and the unified operator interface minimizes
sources of errors from the start, while intelligent information in the display makes searching for errors
much easier.

Magnetic valves must not be energized during pre-purge. Check if valves are in closed
position!

Final Checks

Ø Switch of all purges after completion of all necessary measurements.
Ø Start and stop the burner at least 3 times to check the operation of the program.
Ø Make sure that all safety circuits on the burner and boiler operate properly before leaving the

installation site.

13.06.2017 Rev. 01 19

Pilot Ignition System

Pilot gas burner inlet pressure Pmax= 200 mbar

Emission Measurement

In emission measurements, the following values are accepted as reference according to TS EN 676 +A2
standard.

Ø CO < 100 mg/ kWh
Ø %3 ≤ O2 ≤ %5
Ø NOx < 170 mg/ kWh
Ø Excess air ratio 1,2≤ λ ≤ 1,3

It is important for the boiler to be sealed in order to avoid incorrect measurements during
emission measurements.

Boiler water temperature must be between 40 C˚ and 80 C˚ while making emission
measurement in hot water boilers.

MAINTENANCE

Monthly Maintenance

Monthly maintenance is a comprehensive process where general checks of burner and peripheral
components are performed to prevent possible faults. After completion of maintenance and adjustment
processes, make sure to perform an emission analysis.

Ø Clean the filters on the main line and multiblock.
Ø Check the burner gas tip.
Ø Perform insulation measurements of ignition and ionization electrodes; replace electrodes should

there be leakage to the body.

Ø Check ignition cables and sockets.
Ø Check all wiring points. Tighten loose connections.
Ø Clean the dust and layers accumulated on the fan and air damper.
Ø Check gas line pressure, it must be the same with the first adjusted pressure, otherwise burner load

and emission values will also have changed.

Ø Check all bolts of the burner. Tighten loose bolts.
Ø After starting the burner and adjusting air damper, perform flue gas emission measurement and

check if there is an ideal combustion.

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 Replace ignition and ionization electrodes with new ones.
Ø Clean air fan and clamps.
Ø Check the operating function.
Ø Check boiler thermostats.
Ø Check cleanliness of boiler inside and clean if necessary.

Follow installation directions during maintenance.
