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 compo-
nents or property.
The use of room thermostats, radiator thermostatic
valves, domestic hot water controllers, etc, can
greatly enhance a heating system and we recom-
mend their use.
Only competent personnel should be employed to
carry out your heating installation.
PIPE FITTINGS
Materials used for installation work should be resis-
tant, sound and should conform to the current edi-

INDIRECT DOMESTIC CYLINDER
This cooker can only be connected to an in-direct
domestic cylinder of 136 litres (30 gallons).
See Fig. 12.

HEATING
Care should be taken to ensure that the heating sys-
tem is correctly installed and that it complies with all
relevant codes of practice.
Note:
We strongly advise the use of pipe lagging if
the installation is likely to be exposed to situations
where the temperature will dip to a level consistent
with frost.
The HPB model produces up to 5.8 kW to water on
maximum setting therefore it is necessary to fit a
heat sink radiator. See output on page 3.
DIRECT DOMESTIC CYLINDER (DHW MODEL
ONLY)
A 113 litre (30 gallon) direct domestic cylinder can be
connected to this cooker. (See Fig. 13)
