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 temperature will dip to a level consistent
with frost.
A 15mm system by-pass
must
be fitted not less
than 1.5 meters (4.9ft) from the cooker to allow
correct water circulation for the pump and to
prevent condensation forming in the boiler. This
should be balanced. A heat sink radiator / towel rail
may be installed if desired in addition to the By-
Pass Loop. (See Fig.18 & Fig 24)

GENERAL MAINTENANCE
It is important that the user is familiar with their
heating system and that they ensure regular checks
and maintenance which can limit unnecessary
break-downs.
If in doubt, the user should consult an appropriately
qualified person such as a plumber or heating
engineer.
We recommend that you evaluate the overall
insulation in your house, i.e. attic, external walls,
windows and external doors. Insulation and draught-
proofing can greatly reduce running costs while
equally enhancing living conditions. Also zoning of
areas and fitting of room thermostat can reduce
running costs, (See Fig. 18, 19, 20, 21, 22, 23, 24).
SAFETY VALVE
A non-adjustable 3 bar safety valve must be fitted to
the primary flow pipe adjacent to the boiler
connection ensuring that any discharge will not
create a hazard to occupants or cause damage to
electrical components or property.
