Before commissioning the appliance
Before commissioning the appliance, remove the pro-
tective wrapping.
Thoroughly clean the work-surface and the outside of
the appliance using lukewarm water and detergent.
With a damp cloth eliminate all traces of the rust-proo-
fing applied in the workshop then dry with a clean cloth.
Start-up
Before starting the appliance up, check that its specifi-
cations (category and type of gas used) match those of
the family and group of the gas available locally.
If not, adapt the appliance to the gas family or group re-
quired (see paragraph “Running the appliance on other
types of gas” page 8).
To start the appliance up, see the instructions for regu-
lar use.
Testing the power rating
Use the specific nozzles for the nominal capacity on the
appliance.
Capacity can be of two types:
- nominal, as given on the data plate;
- minimum.
These nozzles are shown in table 1 in the assembly in-
structions.
The following are the operating pressure tolerances to ob-
tain the nominal power according to the agreed nozzles:
- from 15 to 22.5 mbar for gases of the second family
- from 25 to 45 mbar for gases of the third family
(propane).
The appliance will not work outside the above pressure
threshholds.
To adjust the capacity to its minimum value, use the da-
ta in tables 1 (Gas Flow Regulation table).
If you wish to check the nominal capacity further, you
may do so using a gas meter according to the so-called
”volumetric method”.
It is normally enough, however, simply to check that the
nozzles are functioning correctly.
Checking input pressure (Fig. 3)
Input pressure should be measured using a gauge (e.g.
a gooseneck pipe, min. resolution 0.1 mbar).
Remove screw (22) from the pressure socket and con-
nect it to the tube on the gauge; after measuring, the
screw should be retightened absolutely airtight (22).
Checking power rating using the
volumetric method
Using a gas meter and a chronometer, you can read
the volume of gas output per time unit.
The correct volume will be the value of “E” expressed in
litres per hour (It/hr) or litres per minute (It/min).
The following formula is used to calculate the value of “E”:
Capacity should only be measured when the appliance
is at a standstill.
The heat value can be obtained from your local Gas
Board.
To obtain the nominal and minimum capacities in rela-
tion to the nominal pressure, consult table (1- Gas Flow
Setting).
WARNING
It is not possible to adjust nominal capacity in ad-
vance.
Checking power rating when using
LP gas
Check that the type of nozzles used match table 1 spe-
cifications.
Check that the output pressure regulator installed colla-
terally to the plant conforms to the specifications laid
down in paragraph "Testing the power rating" (see data
plate and measure the pressure).
