2.5 PRE-COMMISSIONING CHECK
Ens re that all open-top b rners (where applicable)
and oven linings are properly located, and that oven
grid-shelves slide in and o t easily. Check that all
packing material has been removed.
It is necessary for the gas press re to be checked
before the nit is commissioned, and a s itable
press re ga ge m st be connected to the press re
test point(s) as follows:
Open Top Burners (where applicable).
P ll off the gas tap knobs, and remove the control
panel, th s revealing the test-point.

FIRST ENSURE ELECTRICITY SUPPLY IS OFF
Remove the three Pozidriv screws sec ring the black
control panel, and draw the panel forward on its
slides. Remove the b rner grille (4 Pozidriv screws).
Connect a press re ga ge to the o tlet test point
immediately below the m ltif nctional gas control.
Note that inlet and o tlet points are provided on the
control also.
The gas press re to the open-top b rners is adj sted
by means of the external governor mo nted at the
rear of the appliance, whilst the oven press re is
controlled by adj sting the appropriate screw on the
gas control-valve.
When adj sting the press re on a range (i.e. G1102)
it is recommended that the oven, and two of the open
top b rners be lit d ring the operation.
2.5.2 Adjusting The Oven Burner Pressure
Proceed as follows:
a) If possible, p rge the s pply lines of air. On G1102
ranges, this is simply effected by opening one or
two of the open top b rner taps and applying a light
to the b rner. On oven nits, it may be necessary
to slacken off a joint in the incoming s pply pipe,
taking care to re-tighten.
b) Light the oven, as described in the accompanying
User's Instr ctions. At this stage, take care not to
to ch live connections which are now exposed
behind the withdrawn oven control panel.
c) Check all connections for gas-so ndness, sing
soap and water sol tion.
d) With the press re ga ge connected to the o tlet
press re test point adj st the press re, which
sho ld be 15 mbar (6 in w.g.), by t rning the screw
in the reg lator screw on the gas control. This is
sit ated nder the white plastic cover, which m st
be p lled off. To increase the press re, t rn the
screw clockwise, and vice-versa.
e) Adj st the open-top b rner press re by t rning the
screw in the governor t rret. Replace the protective
cap afterwards.
f) Switch off the appliance by depressing the OFF
b tton on the gas control valve, and t rn off the
electricity s pply at the mains. Replace test point
screws, control panels etc.
2.5.3 Checking The Performance Of
The Controls
Oven
a) Light the oven as detailed in the User's
Instr ctions, set the thermostat at 250
o
C and
allow the oven to heat p, ens ring that the fan is
operating and t rning anti-clockwise when viewed
from the front.
b) T rn the thermostat down to its lowest setting, and
check that the oven b rner goes o t, b t leaving
the pilot b rner lit.
c) T rn the thermostat knob to a high setting,
where pon the oven b rner sho ld re-light
smoothly and with little or no delay.
d) Check that the fan stops, and the oven b rner goes
o t, when the oven doors are opened.
e) Check the operation of the power switch. When
OFF the fan sho ld stop, and the main b rner be
exting ished. The pilot b rner, however, remains
lit.
f) Check to timer. This does not t rn off the gas to the
oven, b t simply provides the ser with an a dible
sign that a pre-set time has elapsed.
g) Depress the oven light b tton and check hat the
light is operational.
Open Top
Light the open top as detailed in the User's Instr c-
tions. Check that the ignition is smoooth and witho t
delay. Repeat this operation several times.
2.5.4 Multifunctional Control
Access to the control is gained pon withdrawal of the
control panel. See section 3.2.1.
The control is an SIT Electrosit 0.810.156 and
contains a n mber of feat res for effecting
adj stments. Refer to Fig re 4.
