HEATING
Care should be taken to ensure that the heating
installation is correctly installed and that it complies
with all relevant codes of practice (see installation
section). If this appliance is being connected to an
existing system, it is strongly recommended to
check the following:
(a) That the system is sound.
(b) That pipework is adequately insulated (where
applicable).
(c) Check all controls, i.e. pump, motorised valves,
time control, radiator valves etc., are operating
satisfactorily and are compatible with the
requirements of the cooker.
(d) Are any modifications necessary to make the
heating system more efficient?
(e) Cleanse the system and add suitable inhibitor.
SAFETY VALVE
A non-adjustable 3 bar safety valve must be fitted to
the primary flow pipe adjacent to boiler connection
ensuring that any discharge will not create a hazard
to occupants or cause damage to electrical
components or property.
Note: We strongly advise the use of pipe lagging
and also the use of a frost thermostat if the
installation is likely to be exposed to situations
where the temperatures will drop to a level
consistent with frost.
The use of motorised valves, room thermostats,
radiator thermostatic valves, domestic hot water
controllers, etc, can greatly enhance a heating
system and we recommend their use.
Only competent personnel should be employed to
carry out your heating installation.
It is important that no external control devices e.g.
economisers are directly fitted to this appliance
unless covered by these installation instructions or
agreed with the manufacturer in writing. Any direct
connection of a control device not approved by the
manufacturer could make the guarantee void.
Note: The cooker must be connected to a
fully pumped system.
