Wega ALE Series Use And Maintenance Manual page 26

In case of connection with a hose, follow the indica-
tions below:
- Use a hose that meets the standards in use (it is
important to replace it periodically as indicated
on the tube stamping);
- the hose must have a maximum length of 1 metre;
- fix the hose to the connector (1) if necessary, in-
stall the conic connector (8) and its seal (7);
- the hose must not be placed near potential heat
sources, they must not reach a temperature
higher than 50 °C;
- the hose must not be subjected to traction or
twisting stress, and they must not have any kinks
in them. It must be possible to inspect them along
their entire length, and they must not come into
contact with sharp objects or sharp corners.
If you need to connect the hose to the machine, we supply a conic
fitting (8) with seal (7) to be installed on the fitting cylinder (1).

when connecting with a pipe: connect the Ø8 copper
pipe to the 1/4 gas connection (1);
check that the type of gas utilised corresponds to the
one indicated on the gas data plate of the machine.
In the case of a different gas, replace the injector (2)
as indicated in the Gas Table in par. 5.9.3 on page
27 and replace the "Preparing gas" label on the
boiler cover with that corresponding to the gas used
(supplied with the injector). Ensure correct supply
pressure by connecting a manometer to the fitting
(3) and check the air pressure between the input
connector to the injector by connecting a pressure
gauge (6) see par. 5.9.4 on page 28 ;
check that the air aspiration height (X) corresponds
to that indicated in the Gas Table see par. 5.9.3 on
page 27 ;
to carry out any adjustments proceed as follows:
- loosen the screw (4);
- move the suction cap (5) to the required height;
- fix the screw (4);
- if, when starting the burner the colour of the flame
is not blue, slightly modify the air aspiration height
until the correct colour is obtained.
as soon as connection is complete, check for any gas
leaks by placing a soapy solution on all connections.
