Orifice
Lift the air ring E. Replace the injectors Fin accordance with
Table 3 and Figure 14 (Ø in 1/100 mm).
The side burner bodies are kept in place by a transversal bar
(H, fig. 16). In order to take them out, unscrew screws I(fig.
17) then G(fig. 15).
Note :When one or more nozzles are changed, the sealing
ring should be changed as well (see gas circuit diagram).
Adjustment of primary air
Put body & cap back on their respective burners, set air ring Eby
sliding it from bottom to top (fig. 14, Table 4).
Note : Normal flames are bluish green except for natural gas flames
which are violet.

Adjustment of reduced flowrate of surface burners
(Figure 18) :
After connection or change of gas, it is crucial to modify this
adjustment.
- Remove the control knob. Light the burner, adjust to
minimum setting, and then use a small screwdriver to set the
adjusting screw J.
Note : Flame is reduced to ¼ of its size in the minimum setting,
the burner must remain lit when changing from maximum
setting to minimum setting.
Refitting the cooking surface :
When refitting the cooking surface, it is vital to tighten
fastening screws (figures 7, 8 and 9). Failure to do so can cause distortion of the cooking surface.
OVEN BURNERS :
Oven orifice : Remove the base, CAUTION: when
refitting place the base underneath the groove on the fascia
(Figures 19 and 20).
Disconnect the connection piece; unscrew screw Kon the orifice holder (Figure 21). Replace the orifice (Table 5).

ELECTRICITY
It is hazardous to put the appliance into service without connecting it to suitable ground.
No liability can be accepted for accidents resulting from non-compliance with this requirement or incorrect grounding.
Connect the equipotential bonding terminal (N, Figure 25).
Before connection, check that the :
Mains voltage is compatible with the appliance’s rated
voltage and thermal output.






Connection :
Use a 3-wire grounded cord rated for 13 A or 4-wire rated for 30 A 125 / 250
VAC, type SRD, SRDT, S, SO or ST.
Where local Codes do not permit grounding through neutral, use a 4-wire power
supply cord or “pigtail” kit. Cord must be agency approved for use with
household ranges.
Remove access door O(Figure.25, gas oven range) or P(Figure 26, 4 electric
oven range).
Connect to terminal block in accordance with figure 28.
Secure the cable by means of cable clamp, item Q (Figure 27).
Refit access door
THE APPLIANCE WHEN INSTALLED, MUST BE
ELECTRICALLY GROUNDED IN ACCORDANCE

appliance (or equivalent) to the wall, this allows for ventilation and
reduces the risk of heat damage.
Screw the 2 brackets Sto the wall according to figures 30, 31 and 32
(screws not supplied), then fit the back spacer vent onto these brackets by using the washers and nuts supplied with the
range.
STABILITY DEVICE INSTALLATION INSTRUCTIONS :
Screw the anti-tip bracket Tto the wall according to figures 30, 31, 32 and 33 (screws not supplied).
Remove the drawer; push the range against the wall until the anti-tip bracket screw goes through the back of the range.
Through the drawer gap, screw the nut and its washer on the anti-tip bracket screw.
