When the machine is working, the pressures of the gas supply, measured in
Pascal, and consequently the outlet pressures of gas taps, which are made
equal by means of a pressure reducer, differ according to some of the Coun-
tries where the lava rock grill is sold. These pressures are indicated in the fol-
lowing table:
COUNTRY Pressure of gas supply / taps present in the Machine
ITALY 0,30 Pascal
FRANCE 0,29 Pascal
GERMANY 0,50 Pascal
Ensure that the pressure reducer is approved.
Ensure that the connecting pipe is approved.
4) Insert a closing tap in between the gas main and the Machine, having an in-
ternal diameter of not less than 18 mm (¾" three quarters of inch) to insulate
the Machine from the gas supply in case of need.
Ensure that the closing tap is approved and place it within easy
reach.
5) Ensure that every burner is switched off. In order to do that, make sure that
the white dot in the knob is in the position marked by the symbol 0 (zero) on
the front part of the lava rock grill.
In
ATTACHMENT 4 the figure illustrates position 1, that is the position of the
knob when the burner is switched off.
6) Having established the connection, open the tap in between the Machine and
the gas main and make sure that there aren’t any gas leakages in the joints.
In
ATTACHMENT 6 the figure illustrates the joints through which the gas is
running, which need to be checked. Only use soap foam for the checking and
spread it over the joints through which the gas is running and make sure that
no gas bubbles are escaping from the joints.
It is strictly forbidden to use a flame to detect gas leakages.
7) If you detect any gas leakage, carry out the following operations for each
burner:
•
Check the distance between the spark plug and the burner and make
sure it is the proper one.
In
ATTACHMENT 7 the figure illustrates the position of the spark plugs
and the way to control them.
•
Follow the procedure to switch on the burners, as described in the In-
structions for Use section, paragraphs 1, 2 and 3.
•
Once the burners are switched on, bring the knob to the position of
maximum power, marked by the symbol
1 (one) and keep it in that po-
sition for a few minutes. Then bring the knob to the position of mini-
