Place the cooker in the intended position and lift out the surface
ground hotplate, checking that the joint between the underside
of the hob and the top of the cooker is intact.
Any joints which have opened should be made good with fire
cement provided.
If the appliance is installed near combustible material then as
well as adhering to minimum clearances in Fig. 1 additional
non-combustible insulation must be fitted to the wall to protect
the area around the flue and fluebox. The insulation must reach
a minimum distance of 150mm either side of the flue/flue box
and follow the line of the flue. The minimum specification for
this material is Superwool 607 LTI with a density of 320kg/m3,
a thickness of 10mm and a self finish. There must be a
minimum 16mm air gap between the insulation board and an
adjacent combustible wall surface. A higher specification
material may be used but the air gap must be maintained
.
Check that the boiler/cooker flueway dampers operate correctly
by turning the knob on the front plate adjacent to the top left
hand corner of the roasting oven door.
NOTE: IT IS NOT VISUALLY POSSIBLE TO SEE THE
BOILER DAMPER AND THIS SHOULD BE CHECKED BY
FEELING THROUGH THE HOTPLATE APERTURE TO THE
BACK OF THE COOKER. THE COOKER DAMPER SPINDLE
OPERATES THE BOILER DAMPER WHICH CAN BE FELT
BY INSERTING HAND INTO FLUEWAY.
Replace the hotplate making sure that it is seating evenly on
the soft rope and that it is approximately 1.5mm proud of the
enamelled top plate, with an equal space all round.
1. Connect pipework to boiler flow and return tappings.
2. Fit the flue chamber which should have a rope seal already
installed. The flue chamber is screwed to the cooker making
a good seal as any air leak at this point will impede the
working of the cooker.
3. Open the firebox and ashpit doors and check that the
reciprocating bottomgrate bars are in position, and the 3
grate plates are in place. The riddling lever will not operate
fully as these plates, if fitted correctly, will lock the
reciprocating bars.
4. Turn the boiler thermostat knob at the rear left hand corner
of the top plate from No.1 (low) to No.8 (high).
NOTE: THE HIGHER THE NUMBER, THE HIGHER THE
WATER TEMPERATURE.
The handrail brackets are held on the front ends of the cooker
top-plate casting. Remove the travel nuts and replace with the
handrail brackets ensuring the fibre protecting washers are in
position. Insert the handrails with fitted endcaps into the
brackets, positioning them correctly, and tighten the locating
bolts (Fig. 9).
After completing the installation, the heating contractor should
demonstrate to the user the operation of the appliance and the
routine cleaning method.
The protective grease should be removed from the hotplate
before lighting.
Check that the system is full of water and free from air locks.
When lighting, check that the cooker flueway damper is set to
‘C’ cooker, the flue box damper is fully out and the chamber
door is closed, The thermostat should be at 8, maximum and
the spinwheel open. The secondary air slide inside the firebox
door should be set to open. These settings will allow maximum
draught for the firebox and flue. The cooker must not be left in
this condition, as the open spinwheel is not controlled
thermostatically.
The firebox door and the ashpit door are interlocked so the top
door has to be opened before the bottom. Add paper and
kindling to the grate and light. Close both doors. After a few
minutes the fire should pick up and gradually add larger pieces
of fuel. Allow the cooker to establish the fire and gradually
reduce the amount of air going into the firebox. Start closing
down the spinwheel, so that the cooker is working on the
thermostat. It may be that in normal running the spinwheel
needs to be slightly open depending upon the heat
requirement.
For the first couple of days do not overfire. The cast iron inside
the cooker will build up heat gradually and overfiring may cause
damage.
NOTE: SMOKE/SMELL EMITTED DURING INITIAL USAGE
Some parts of the cooker have been coated with a light
covering of protective oil. During initial operation of the cooker,
this may cause smoke/smell to be emitted and is normal and
not a fault with the appliance, it is therefore advisable to open
doors and or windows to allow for ventilation. Lift the lids to
prevent staining the linings.
