SECTION 1 - INSTALLATION
1.2 SITING
The unit must be situated on a reasonably level
surface. Althou h the feet are adjustable and facil-
itate levellin , the adjustment ran e is limited.
Installation must be executed in accordance with
local and/or national re ulations, as listed on the
cover of this manual. A competent installer must be
employed.
Installing Clearances
At least 150mm must be allowed from any wall.
To facilitate servicin , it is recommended that a space
of at least 400 mm should be allowed from any side
wall. If the unit is bein installed as part of a suite, it is
further recommended that it be positioned at the RH
end to provide unrestricted access for servicin .
A minimum vertical clearance of 750mm must be
allowed between the top ed e of the flue outlet and
any overlyin surface.
If unit is to be installed in a suite, centrally or adjacent
to a wall with a boxed in void at the rear, it is vitally
important that the void be adequately ventilated.
This will ensure a supply of air to the motor coolin
fan at the rear of the oven.
1.3 VENTILATION
Adequate ventilation, whether natural or mechanical
must be provided to supply sufficient fresh air for
combustion and allow easy removal of combustion
products which may be harmful to health.
The flue dischar es vertically from the slotted uard
at the top of the appliance. It must not be directly
connected to any flue, mechanical extraction system,
or ductin etc., which leads outside the buildin .
The appliance is best dischar ed under an open
canopy which connects with a ventilatin system.
Recommendations for Ventilation of Caterin
Appliances are iven in BS5440 : 2.
Furthermore, to ensure sufficent room ventilation,
uidance on the volume of ventilation air required for
different types of caterin equipment is provided in
the followin table.
For multiple installations, the requirements for in-
dividual appliances should be added to ether. In-
stallation should be made in accordance with local
and/ or national re ulations applicable at the time.
A competent installer MUST be employed.
1.4 GAS SUPPLY
The incomin service must be of sufficient size to
supply full rate without excessive pressure drop. A
as meter is connected to the service pipe by the
local as re ion or its sub-contractor. Any existin
meter should be checked by the as re ion to ensure
the meter is of adequate capacity to pass the required
rate of as for the oven in addition to any other as
equipment installed.
Installation pipe work should be fitted in accordance
with IGE/UP/2. The pipe should not be smaller than
the as inlet connection on the appliance
i.e. Rp
1
/
2
(

" B.S.P.)
An isolatin cock must be located close to the
appliance to allow shut-down durin an emer ency
or servicin . The installation must be tested for as
soundness as specified in IGE/UP/1. The adjustable
overnor supplied must be fitted in an accessible,
spilla e-free and reasonably cool position.
1.5 ELECTRICAL SUPPLY
Each oven is equipped with a len th of 3-core flexible
cord for connectin to an electrical supply. A standard
13 amp socket outlet can be used, in which case the
plu -top must be fitted with a 3 amp fuse. If the supply
is throu h a distribution fuse, box, it must be via a
fuse havin a maximum ratin of 5 amp.
Warning
THIS APPLIANCE MUST BE EARTHED.

o
C. The as supply may
contain some air so repeat li htin procedure,
payin particular attention to instructions to be
followed in event of controls safety lockout.
d) Adjust pressure overnor (NATURAL GAS ONLY)
to set burner pressure (Section 1.9). To increase
pressure turn screw inside overnor turret
clockwise. Anti-clockwise to reduce pressure.

3.26 DOOR LINKAGE ADJUSTMENT
and TENSIONING
Due to operational stretchin of components or
removal for maintenance, occasions will arise when
doors linka e mechanism will require adjustment.
The method to use is as follows:
Push door handle until RH door makes contact with
seal. LH door should now be 12 to 15mm proud of
RH door at vertical join - see Fi ure 2. If LH door
distance is less than this dimension, slacken both
turnbuckle locknuts and rotate left turnbuckle to
reduce len th on rod and ri ht turnbuckle to increase
len th on rod by same amount.
Repeat procedure until desired dimension is
achieved.
If left door distance is reater than desired settin
then the above procedure should be carried out in
reverse.
After doors are synchronised, the linka e should be
put under tension by sli htly twistin the turnbuckles
toward one other by the same small amount.
The tension should be such that no free play is
available between chains and sprockets.
3.27 DOOR LINKAGE ALIGNMENT
When linka e components have been disturbed
durin repair, the initial coarse ali nment of the
assembly will be achieved by positionin the chains
on their sprockets as indicated in Fi ure 3. The doors
should be in the closed position whilst carryin out
this operation.
