Unpacking and Assembly
Each unit requires the handle, chimney and legs to be fitted. All these are packed
inside the oven. Single oven units also have a storage shelf with stainless steel tray
to be fitted between the legs. The tray is packed on top of the unit, the shelf under
the unit. Remove the oven wire rack, four tiles and the centre support bar.
Single Oven Units
The unit is attached to the wooden pallet by two packing straps. Remove and
discard.
Lift unit out and place on its back to enable the legs to be fitted. Attach with the nuts,
bolts, spring and flat washers supplied. Attach the storage shelf between legs and fit
stainless steel tray on top of shelf.
Lift unit up onto its legs and adjust feet as required to level the oven. Fit door handle
with the screws already in the door. Push chimney/hood assembly down into the rear
ducting until the stainless steel hood touches the top cover panels. Refit tile support
bar, and tiles. Oven wire rack when required can be positioned on top of the tiles or
higher on either of the side runners of the oven.
Double and Triple Units
Start with the bottom units (as marked on the packing). Remove and discard the two
packing strips which hold the unit to the pallet. Place units on its back to enable the
legs to be attached. Attach legs with the nuts, bolts, flat and spring washers
supplied. Lift unit onto its legs and adjust feet as required to level the oven. Fit the
door handle with the screws already in the door. Refit oven tile support bar and tiles.
Fit chimney into the rear ducting. Approximately 65mm (2½") should protrude above
the top corners.
Unpack upper unit(s).
Unscrew the rear brackets from the pallet. Remove the stainless steel side trim
pieces along the bottom of the unit. Lift unit onto the bottom unit taking care to align
the bottom chimney into the ducting of the Upper unit. This upper unit screws to the
bottom unit at the rear the same as it was attached to the pallet.
Attach door handle with the screws already in the door. Attach side trim pieces. Fit
chimney to the upper unit.

Electrical Connections
Loosen the two screws on the left side of the control panels and hinge control panel
open. Terminals are provided permitting single ovens to be connected to a single or
two phase supply with twin or triple deck units are suitable for two or three phase
supply. Access to these terminal studs may be improved by removing the bottom
stainless steel front cover and unscrewing the terminal board bracket (screws either
side of the fuses) and bringing the board and bracket out in front of the unit.
Wiring Entry
When viewed from the front of the oven, the wiring entry is in the back panel in the
right hand corner. A hole diameter 32mm (1¼") is provided for mains entry, extra
holes for interconnecting wiring of double and triple units allows for one mains supply
if desired.
Wiring Double or Triple Deck Units
Each deck requires two phase supply. Any two of a 240v three phase and neutral
supply can be used, which ever gives the most balanced loading in the kitchen. To
facilitate this, terminal studs for three phases have been supplied in each unit. this
will also allow looping of the unused phase to the deck above.
INSTALLATION
Many other combinations are available. The oven loads may not be balanced,
however in practice the average current drawn by the top elements of each unit (A1)
is considerably less than the bottom elements (A2). Therefore for double deck units
one phase should connect to the top elements of both units, and each of the other
two phases to the bottom elements.

Converting to Double and Triple Units
These units are capable of being tiered up to three ovens high. Extra ovens may be
added at any time to single units to convert into double or triple oven units. When
ordering extra oven units please specify if these are to be added to existing ovens to
create double or triple deck units. Additional components and appropriate legs will
accompany the additional unit.
If however two existing single units are to converted "in field" to a double unit a kitset
is available Part number 13065. Instructions with kitset.
If an existing double unit and an existing single unit are to be converted "in field" to a
triple unit, use kitset Part number 13066.
Note: Units up to serial number 1805 cannot be stacked with units serial numbers
over 2000 due to major modifications with oven venting. The above kitsets are for
units of serial numbers over 2000 only.
INSTALLATION

General
All ovens have a ceramic tiled hearth and are heated by sheathed tubular elements
situated in the top of the oven and below the hearth. All elements are controlled by
the thermostat from 150-350°C (300-650°F). In addition the bottom element is under
the control of a three heat switch, whilst the top elements inner and outer coils are
each controlled by Energy Regulators. Pilot lamps indicate which elements are
turned on, and will go out when the oven reaches the correct temperature.
Controls
When pre-heating the oven use only the bottom elements. Ovens fitted with a tiled
hearth take much longer to preheat from cold than a conventional oven as it is the
purpose of the tiles to store heat and then act as a reservoir distributing the heat
evenly throughout the oven. If the top elements are used during preheating, this
radiant heat will cause the thermostat to switch off long before the bottom element
has heated the hearth. As a guide, i.e only the bottom element is used for pre-
heating from cold, it will take approximately one hour to reach 200°C.
OPERATING INSTRUCTIONS
To set timer, turn to 60 minutes then
back to the required time. When
complete, the timer will ring for about
three seconds. The timer does not
turn the oven off.
An efficient ventilating system which is fully adjustable is fitted to each oven. The
vent control is located between the control panel and door. The vent should only be
opened the minimum amount to evacuate surplus steam from the oven.
Recommendations
The oven should be pre-heated with the bottom element only to evenly heat the
hearth and oven panels. For many products, cooking can best be carried out by
placing them directly on the tiled hearth. An optional extra steel hearth cover is
available to reduce the wear on baking trays -when used directly on the tiled hearth.
Some products such as certain types of sponges, Madeira cakes etc are best cooked
with an air gap between them and the tile to avoid overcooking the bottom of the
goods due to direct heat. The wire rack supplied may be placed directly on the
hearth, or any of the support brackets above. In addition to placing the goods on the
wire rack above the tiles, the bottom elements may be reduced to "MED" or "LOW"
settings and the top elements increased until a balance of bottom to top heating is
achieved.

-9-
When top heat is required for browning purposes the top elements controls can be
set to equivalent settings or can be varied i.e. the outer element set higher than the
inner or vice versa. The actual settings to be determined by the type of goods being
cooked and the preference of the operator.

SERVICING
DOOR: Ensure power supply is turned OFF.
To adjust the spring counter balance, loosen the two screws on the left hand side of
the control panel and swing control panel open. The spring is adjusted by a wing nut.
Screw in clockwise tighten spring tension. To replace spring, chain or chain roller
also remove bottom stainless steel cover (two screws each end) pull forward to re-
move. Remove cover between door and control panel (open door and remove two
screws). Pull cover out at bottom and down to disengage location tabs from top
cover. Vent knob will prevent complete removal of this panel, so it more room is re-
quired, the vent knob can be removed from the shaft. Close door and taking care
that it does not fall under its own weight, release the spring tension and unhook the
spring from its adjusting screw. Spring, chain or chain roller may now be replaced.
To remove door, proceed as above, but also remove the cover panel to the left of the
door (open door and remove two screws). Pull cover out at the bottom and down to
disengage location tags from the top cover. Remove the bolts holding the hinge
bearing castings and lift door clear.
Reassembly in reverse order, but adjust door up and down when closed before tight-
ening the hinge bearings. Door should sit hard against oven front (package hinge
bearings as required) and should be parallel to top cover.
WINDOW GLASS REPLACEMENT (700GD ONLY)

THERMOSTAT
To remove a complete thermostat from the oven and control panel, unscrew the phial
cover inside the oven. Pull off thermostat knob and remove the two screws. Remove
wiring and replace.
CALIBRATION
The thermostat controls all elements of the oven. Place a thermocouple in the oven
centre (top rack height), with the probe in the air. Set oven to a suitable temperature,
and allow oven to cycle three times. Disregard first cycle and record the oven
maximum and minimum temperatures during the last two cycles. The average of
these two readings is the oven temperature, and should correspond with the control
knob markings. To change or correct the calibration of this thermostat, there is a
screw inside the thermostat shaft. Turn clockwise to decrease or anti clockwise to
increase.
