FLOOR PROTECTION

It is recommended that the appliance is installed on
a solid, level, concrete base of non combustible
hearth conforming
Regulations must extend 350mm in front of the unit
and 350mm from the sides of the front edge. This
will provide protection from sparks and embers
which may fall out when stoking on refuelling.

PLUMBING

PIPE THERMOSTAT

The fitting of a pipe thermostat to the flow pipe is
essential in order to activate the water circulation
pump when the water reaches the selected tem-
perature.
When the water temperature falls below the select-
ed temperature the pipe thermostat will cut off the
water circulation pump in order to allow the boiler
to recover.

REGULATIONS

The plumbing must be in accordance with all rele-
vant regulations and practices. It must include a
gravity circuit with expansion pipe, open to the
atmosphere. The central heating will normally be
pump-driven as with other types of boilers.

GRAVITY CIRCUIT

The gravity circuit consists of the domestic hot water
tank of 135 litres indirect cylinder, fixed in an upright
position, recommended for hot water storage and it
should be connected to the boiler by 28mm diame-
ter flow and return piping. The pipes should not
exceed 7.8 meters (25ft) in length and cylinder and
pipework should be fully lagged. The shorter the run
of pipe work the more effective the water heating.
There must be no gate valves on this circuit and it
must have an expansion pipe exhausting to atmos-
phere. Cylinder and pipe work should be lagged to
minimise heat loss.

ing systems and must not be regarded as a work-
ing drawing.
