2.2.3. Lower oven compartment door
If required a handle for the lower oven
compartment door is packed inside the unit.
2.2.4. Oven door handle
To fit the oven door handle :
- Remove the oven door 8 (ill. 7).
- Remove the two screws 1 (ill. 7) and hold the inner
door 4 half open with a block 2.
- Unscrew the struts 6.
- Place the nuts 7into the slot of the handle supports 5
et place the fiber washer 3 between the handle and the
door.
- Centre the handle before screwing up the struts.
- Fit the inner oven door and replace the oven door.
2.3. The chimney
The chimney is the key to a successful installation and
the following key areas should be checked.
Height
The minimum height should be 5 metres with the termi-
nal at least 1 metre from the roof surface and in a clear
area away from possible downdraft. If in doubt always
increase the chimney height. This will help to ensure an
adequate draft and clearance of the flue gases from the
area of the building.
Insulation
The chimney needs to be warm from bottom to top and
should be adequately insulated. Cold chimney and cool
flue gas temperature will result in tar formation
and smoke emission into the room.
Resistance
If the chimney has a horizontal section at the appliance
outlet, this should not exceed 30 cm. Any changes in
direction should be gradual (15 degrees maximum) and
the chimney system must not incorporate more than two
bends. The straighter the chimney, the less resistance.
Any resistance will slow down the flue gases and help
to create a build up of tar deposits.
Draft
The appliance requires a draft of between 04" and 07"
W.G. to burn effectively. This is the up draft of air through
the appliance. It is the result of the height of the chimney
and heating of the column of air within the chimney. An
inadequate draft will cause soot and tar formation in the
chimney.
The appliance requires a class 1 chimney. Existing un-
lined chimneys should be lined with a liner suitable for
use with solid fuel burning appliances. If there is no
existing chimney, there are a variety of prefabricated
systems available and it is recommended to
discuss your particular application with a chimney
specialist.
2.4. Connection to chimney.
• TOP FLUE OUTLET
Use the draught control box (ill. 17).
The draught control box can be dismantled to give
access for flue cleaning.
• REAR FLUE OUTLET
It is not possible to use the draught control box in this
position. Provision should therefore be made to fit a
draught regulator.
Important ! When the rear flue connection is used, cut
Don’t forget to fit with an airtight seal the flue collar and
the blanking plate which are supplied and packed in the
firebox.
Caution : Sufficient access must always be left for chim-
ney sweeping and appliance cleaning.
2.5. Connecting the central heating cir-
cuit.
In any installation, Relevant Building Codes and Practi-
ces must be observed.
• The appliance is not designed as a pressure vessel,
so the circuit must be left open to the atmosphere and
must not be constructed to allow any pressure build-up
to occur (ill. 8).
• A gravity circuit MUST be provided, as a fail safe heat
loss in the event of a circulating pump failure or a power
cut. To achieve this, ensure that large diameter pipes
leading to upstairs radiators have a direct flow from the
boiler, or install a big hot water cylinder with large
diameter heat exchanging coil, situated above the coo-
ker.
The layout of the heating circuit can be designed in any
fashion that suits the house, as the pump will ensure
circulation of hot water to all points, but the hot water
cylinder or a small heating circuit must be engineered
to work by gravity, Use 1 inch min. I.D. pipe (28 mm) to
the cylinder, ensure that the cylinder has a 314 inch
min. I.D. coil wound from top
to bottom, and that the inlet is above the boiler and the
outlet is above the return tapping of the boiler.
