Check that the appliance has been prepared (category and type of gas) equivalent to the family of gas available on site. If not, it is necessary to
convert the appliance to whatever is available. See the paragraph "Conversion to other types of gas".
The appliance must be used with the correct injectors for its thermal power rating (See table 5 in the "Technical data").
The operation of the appliance with its heating capacity depends on the inlet pressure and the calorific power of the gas.
The pressure range (inlet pressure) within which the appliance is allowed to operated is stated in table 6b "Inlet pressure" of the paragraph
"Technical Data". The appliance shall not be operated out of the given pressure range. If pressure should differ from the figures stated in table
6b, advise the gas board or the company which has installed the system.
The lower calorific value of the gas can be checked with the supply company or agency, and should comply with the information given in table 5
"Gas data" in the "Technical data" heading.
−
The feed pressure is measured using a liquid pressure gauge ( e.g. a U-shaped pressure gauge, minimum definition 0.1 mbar). The supply
pressure can be measured directly at the inlet pressure intake on the gas feed pipe. The inlet pressure intake can be reached by opening the
lower front panel once the two side screws have been removed. (See figure "Measuring the inlet pressure ").
−
Before connecting the manometer, the screw of the pressure port must be loosened.
−
Connect the U-shaped pressure gauge while the appliance is operating to measure pressure.
−
The pressure reading on the gauge should be in the admitted pressure range stated in table 6b "Inlet pressures" of paragraph "Technical data".
If pressure figures should not be correct, apply to the gas board or the company which has installed the system.
−
Having read the pressure, re-tighten the screw carefully.
The sealed adjuster screws on the gas solenoid valve must not be tampered with, otherwise any guarantee rights shall be
-
forfeited immediately.
Primary air can be considered correctly adjusted if no flame lift is ensured when the burner is cold and the injector lights when the burner is hot.
The distance "H" (see figure "Primary air regulation") recommended for primary air adjustment is stated in table 5 in the "Technical data".
Once all the connections have been made, the appliance and the overall installation must be checked following the directions given in this manual.
Check in particular:
−
that the protective film has been removed from the external surfaces;
that connections have been made in accordance with the requirements and directions indicated in this manual;
−
that all safety requirements in current standards, statutory regulations and directives have been met;
−
that the water and gas connections are leak-free;
−
that the electrical connection has been performed according to standards.
−
Now the appliance can be ignited following the instructions for use and controlling the following points:
−
progressive ignition of the burner;
−
even flames;
−
flame security: check these points at both minimum and maximum output.
Check that the flue gas exhaust is not clogged and that they are expelled without any hindrance.
−
The test report must be completed in full and submitted to the customer who should then sign in acceptance. With effect from this moment, the
appliance is covered by the manufacturer's warranty.
−
To convert the appliance for use with another type of gas, the injectors on the main burners and on the pilot burner need to be replaced. (See
table 5 and figure "Main burner").
−
All the injectors needed for the different types of gas are contained in a bag supplied with the appliance.
−
The supply pressure and the manual setting of minimum output should also be checked. (See table 4 – Minimum output setting).
−
The injectors can be reached by removing the lower front panel, once the two side screws have been unloosed.
−
Disconnect the tube with the injectors, unloose the screws and remove.
−
Use a fixed wrench SW11 to unscrew the injector and replace it with a suitable one.
−
Re-install the primary air regulation bracket at the distance "H" as shown in table 5, see also "Primary air regulation".
The injector of the pilot burner can be reached by removing the lower front panel. Remove the side and lower screws.
–
The pilot burner is in the front of the combustion chamber.
–
Unloose the screw and replace the injector with an appropriate one.
