GENERAL STANDARDS This manual is an integral and essential part of the product and must be given to the installer. Read the warnings given in this manual as they supply important indications regarding installation, use and maintenance safety. Keep this manual carefully for future reference. The burner must be installed in compliance with the Standards in force, according to the manufacturer’s instructions and by qualified staff Incorrect installation can cause injury/ damage to persons, animals or objects, for which the manufacturer cannot be held responsible. - Page 4 any air duct or ventilation grid and external dissipation, with the purpose of preventing: - the formation of toxic/ explosive gas mixtures in the air of the burner room; - combustion with insufficient air, from which dangerous, costly and polluting functioning occurs. The burner must always be protected from rain, snow and freezing.

Page 23: Functioning Cycle
FUNCTIONING CYCLE Burner control Ignition On closure of the heat request contact and when the correct status of the air pressure contact has been verified, the fan motor is inserted and the air damper total opening is controlled.On reaching total opening of the damper and switch-over of the air pressure switch contact has been verified, the pre-ventilation time starts during which the flame amplifier test is performed along with components associated to safety functions. - Page 24 corresponding to start-up flow rate (with gas flow always closed). c) Formation sequence of the start-up flame: the coils relative to the gas solenoid valves are excited and the gas regulator is partially open in relation to the start-up air pressure. d) Passage sequence to the main flame or second stage: the servo-control activates the opening of the air (up to maximum flow rate calibration) whose increase in pressure causes the gradual increase of the gas flow rate.

ADJUSTEMENT Check some adjustments before switching on the burner. The air actuator has been factory pre-calibrated. The high flame cam must be adjusted between 80 and 90° and the low flame cam to about 30°. Air servo-motor regulation (G 1300 - G 2000) The air damper is activated by an electric servo-control. - Page 42 If the burner is to operate inside the operating range where a gas diaphragm is present, you must install it. Gas reduction diaphragm - (G 1300) When the maximum power of the burner is selected inside the shaded area (see Fig. 1), to increase the gas pres- sure signal in order to maintain the gas signal and air signal ratio within the operational limits of the valve, insert the gas reduction diaphragm (DG) provided with the burner.
- Page 43 Gas reduction diaphragm (only natural gas) - (G 2000) When the maximum power of the burner is selected inside the shaded area (see Fig. 4), to increase the gas pres- sure signal in order to maintain the gas signal and air signal ratio within the operational limits of the valve, insert the gas reduction diaphragm (DG) provided with the burner.

- Page 52 Gas diaphragm (natural gas only) Diaframma gas (solo gas naturale) For proper burner operation in the event of particular boiler-burner-chimney couplings, or with low back pressure in the combustion chamber, you may want to install the gas diaphragm anyway inside the entire burner operating Nel caso di particolari accoppiamenti caldaia-bruciatore-camino, o nel caso di contropressioni basse in camera range.
- Page 53 Gas and air pressure switch adjustment Minimum gas pressure pressure switch The gas minimum pressure pressure switch prevents burner start-up of stops it if it is functioning. If the gas pres- sure is not the minimum envisioned, it must be calibrated at 40% lower than the value of the gas pressure, which functions with maximum flow rate.
- Page 54 Air pressure switch regulation The air pressure switch has the task of putting the burner into safety or block conditions if the combustion air pres- sure is missing. This will be calibrated lower than the air pressure value at the burner when this is at nominal flow rate with 1st flame functioning, verifying that the value of CO does not exceed the value of 10.000 p.p.m.
- Page 55 Electrodes positioning (G 1300 - G 2000) Two electrodes are envisioned for ignition and one for flame control: these must not touch the deflector or other metal parts for any reason as they would loose their function, compromising burner functioning. It is good practice to check the correct position after every intervention on the head.

Page 56: Functioning Controls
FUNCTIONING CONTROLS Combustion control In order to obtain the best combustion yield and with respect to the environment, it is recommended to use suitable instruments to control and regulate combustion. Fundamental values to consider are: ● CO . It indicates with which air excess combustion takes place; if the air increases, the % value of CO decre- ases, and if the combustion air decreases the CO increases. - Page 57 c) Carry out a functioning cycle and, when burner ignition has been checked, close the gas supply in order to obtain flame switch-off:check the repetition of a cycle and consequent block shutdown caused by no ignition at the end of the safety time! d) Carry out a functioning cycle and, when burner ignition has been verified, open the contact relative to the air pressure switch:verify the immediate switch off of the solenoid valve and consequent block shutdown caused by air pressure switch anomaly after 10s!
