ll rooms require an openable window, or equivalent
and some rooms will require a permanent vent a

For room volumes up to 5 m 3 an air vent of 100cm 2
is required.
For room volumes between 5 m 3 and 10 m 3 an air
vent of 50 cm

If there are other fuel burning appliances in the
same room BS 5440: Part 2:1989 should be
consulted to determine the air vent requirements.
Gas connection
Make sure that the appliance is adjusted for
the gas type available (see the label under the
appliance). Follow the instructions indicated in the
chapter “gas transformations and adjustments”
for the possible adaptation to different gases. The
appliance must be connected to the gas system
by means of stiff metal pipes or flexible steel pipes
having continuous walls, in compliance with the
regulations in force.
Gas enters the appliance through a cylindrical
threaded male gas union (1/2”).
The connection must not stress the gas ramp.
Once the installation is over, check the connection
seal with a soapy solution.
ATTENTION: Make sure that the gas supply
pressure of the appliance obeys the recomend-
ed values
Electric connection
The connection to the electric grid must be carried
out by qualified personnel and in conformity with
the regulations in force.
The voltage of the electric system must correspond
to the value indicated in the label under the
appliance. Make sure that the electric system is
provided with an effective ground connction in
compliance with the regulations and provisions of
the law. Grounding is compulsory.
This device must be at a suitable opening distance
from the contacts in order to allow the entire
disconnection in case of overvoltage category III ,
in accordance with installation rules
Replacing the nozzles
If the equipment is adjusted for a type of gas that is
different from the one available, it is necessary to
replace the burner nozzles.
The choice of the nozzles to replace must be
made according to the table of the “technical
characteristics”.
Act as follows:
- Remove the racks and burners.
- By means of a straight spanner L, unscrew the
nozzle U (fig.8-8/A) and substitute it with the
corresponding one.
- Tighten the nozzle strongly.
Adjusting the burners
The lowest flame point must always be properly
adjusted and the flame must remain on even if
there is an abrupt shift from the maximum to the
minimum position.
If this is not so, it is necessary to adjust the lowest
flame point as follows:
- start the burner up;
- turn the tap up to the minimum position (small
flame);
- remove the knob from the tap rod;
- introduce a flat-tip screwdriver in the hole F of
the tap (fig.9) and turn the by-pass screw up to a
proper adjustment of the lowest flame point.
As regards G30 gas burners, the by-pass screw
must be tightened completely.
MAINTENANCE
Replacing the power supply cable
If the power supply cable should be replaced,
it is necessary to use a cable with a section of
3x0.75mm 2 for the version all gas and 3x1 mm 2
for the version mixed, type H05VV-F or H05RR-F,
complying with the regulations in force.
The connection to the terminal board must be
effected as shown in fig.10:
brown cable L (phase)
blue cable N (neutral)
green-yellow cable (ground)
