leakage tests!
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 page 8 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 page 7
“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 page 7, 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 page 8 “Gas data” in the
“Technical data” heading.
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 page 8 “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.
