PART II: INSTALLATION PART II: INSTALLATION MOUNTING AND CONNECTING THE BURNER Transport and storage If the product must be stored, avoid humid and corrosive places. Observe the temperatures stated in the burner data table at the begin- ning of this manual. The packages containing the burners must be locked inside the means of transport in such a way as to guarantee the absence of dangerous movements and avoid any possible damage.
Page 19
PART II: INSTALLATION Matching the burner to the boiler The burners described in this manual have been tested with combustion chambers that comply with EN676 regulation and whose dimensions are described in the diagram . In case the burner must be coupled with boilers with a combustion chamber smaller in diameter or shorter than those described in the diagram, please contact the supplier, to verify that a correct matching is possible, with respect of the application involved.
Page 20
PART II: INSTALLATION GAS TRAIN CONNECTIONS WARNING: before executing the connections to the gas pipe network, be sure that the manual cutoff valves are closed. ATTENTION: it is recommended to mount filter and gas valves to avoid that extraneous material drops inside the valves, during maintenance and cleaning operation of the filters (both the filters outside the valves group and the ones built-in the gas valves).

PART II: INSTALLATION Depending on the installed pump, it is possible to design the plant for single or double pipe feeding line Single-pipe system: a single pipe drives the oil from the tank to the pump’s inlet. Then, from the pump, the pressurised oil is driven to the nozzle: a part comes out from the nozzle while the othe part goes back to the pump.

PART II: INSTALLATION About the use of fuel pumps Do not use fuel with additives to avoid the possible formation over time of compounds which may deposit between the gear teeth, thus obstructing them. After filling the tank, wait before starting the burner. This will give any suspended impurities time to deposit on the bottom of the ...
PART II: INSTALLATION ELECTRICAL CONNECTIONS WARNING! Respect the basic safety rules. make sure of the connection to the earthing system. do not reverse the phase and neutral connections. fit a differential thermal magnet switch adequate for connection to the mains. WARNING! before executing the electrical connections, pay attention to turn the plant’s switch to OFF and be sure that the burner’s main switch is in 0 position (OFF) too.

PART III: OPERATION PART III: OPERATION DANGER! Incorrect motor rotation can seriously damage property and injure people. DANGER: During commissioning operations, do not let the burner operate with insufficient air flow (danger of formation of carbon monoxide); if this should happen, make the gas decrease slowly until the normal combustion values are achieved. WARNING: before starting the burner up, be sure that the manual cutoff valves are open and check that the pressure upstream the gas train complies the value quoted on paragraph “Technical specifications”.

PART III: OPERATION Fuel selection: In order to start the burner with gas or light oil, the operator must commute the selector on the burner control panel on (1) = gas, or (2) = light oil. If the selector is set on (1) the gas cock must be open, while the light oil cock must be closed. Viceversa if the selector is set on (2). CAUTION: if the fuel chosen is oil, be sure the cutoff valves on the feed and return pipes are open.

APPENDIX: PROBES CONNECTION To assure the utmost comfort, the control system needs reliable information, which can be obtained provided the sensors have been installed correctly. Sensors measure and transmit all variations encountered at their location. Measurement is taken based on design features (time constant) and according to specific operating conditions.With wiring run in raceways, the sheath (or pipe) containing the wires must be plugged at the sensor's terminal board so that currents of air cannot affect the sensor's measurements.
