Introduction
The Benson Jetstreme 4+ series of
highly
efficient oil fired boilers
combine
the
benefits of
advanced design with well proven construction techniques
and
modern
manufacturing processes.
They operate at high efficiency with clean combustion
and
a
low
operating noise level.
The heat exchanger is enclosed within
an
insulated jacket
with
secondary insulation attached
on
the
inside
of
the
case. The case is finished
in
white
powder
coat enamel
and
is styled to blend into
any
kitchen. The controls are enclosed behind
an
hinged panel
on
the
front of
the
appliance
thus
reducing possible accidental
damage
to them.
A flame viewing port facility is located
at
the
front of the boiler directly behind
the
front panel.
A combustion test point is located
on
the flue spigot
of
the
boiler to enable the commissioning
engineer to carry
out
his setting checks at a convenient point.
The Jetstreme 4+
range
is available for
both
Conventional
and
Balanced Flue systems.
The
Balanced Flue range is extremely versatile offering several configurations for the installation of the
terminal.
The Jetstreme 4+ range
of
both Conventional
and
Balanced Flue Appliances are designed to
operate
on
Kerosene fuel oil
(28
sec). The Conventional Flue appliance can also
be
operated
on
gas
oil
(35
sec), however
it
is not recommended that
the
Balanced Flue appliances are operated
on
this
fuel as combustion problems could occur. All boilers are supplied
with
the
burners
adjusted for
use
with Kerosene (class C2)
28
sec fuel oil. Should the
use
of
gas oil (class D) 35 sec
be
required to
be
used with a Conventional Flued appliance
then
the modification
must
be
carried
out
at
the time
of
installing
and
commissioning.
Although the Jetstreme range of boilers will operate successfully
on
a gravity
hot
water system
it is recommended that a fully
pumped
system is used for both hot water
and
central heating
if
installing a
new
system. The boiler is suitable for
open
vent
and
pressurised systems, however if a
pressurised
system
is
used,
the
manufacturers
recommendations
for
the
use
of
the
auxiliary
components
must
be
adhered
to,
and
pressure
must
not exceed
45
psi
(3
bar).
The Jetstreme
4+
boiler is
approved
by
BSRIA
(the Building Services Research & Information
Association) for OFTEC.
