HIGH UPDRAUGHTS
Tall chimneys may develop excessively high up-
draughts which prevent the appliance operating cor-
rectly.
It is recommended that a proprietary brand adjustable
flue draught stabiliser having an openable cross sec-
tional area of 182.5sq cm (6”ø pipe) be fitted above
the flue pipe connection, either in the brickwork or into
a right angle ‘T’; fitting in the flue pipe position that will
not inconvenience appliance operation or mainte-
nance.
COOKER CLEARANCE
The Cooker should not be installed at zero clearance
to combustible materials. The sides should have a
minimum clearance of at least 75 mm (3”) from com-
bustible materials unless otherwise fully insulated.
This cooker is supplied with a back filler piece which
should be used with fitting the cooker between
kitchen units. This filler piece is mounted to the wall
behind the cooker using the appropriate screws and
rawl plugs (not supplied) and allows adequate clear-
ance from the front of the cooker to the front of the
kitchen units for door opening (see Fig.8 & 8a)

TESTING & COMMISSIONING
After completing the installation, the heating contrac-
tor 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.
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 emit-
ted 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.
Ensure all parts are fitted in accordance with the in-
structions.
On completion of the installation allow a suitable pe-
riod of time for any fire cement and mortar to dry out,
before lighting the stove. Once the stove is under fire
