2.3. CHECKING THE OPERATION OF THE GAS SYSTEM
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.
2.3.1. CONTROL OF THE GAS INLET PRESSURE
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.
Warning! The sealed adjuster screws on the gas solenoid valve must not be tampered with,
otherwise any guarantee rights shall be forfeited immediately.
2.3.2. CONTROL OF PRIMARY AIR FLOW
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”.
