Specification
Cabinet: Machine punched and folded to form a robust
monocoque cabinet with access to the burner and controls
compartment via a front located access door. For added
weather protection all external panels are manufactured
from electro-zinc plated steel and then finished with
stove hardened epoxy powder coat with a durable
Kestrel Grey paint finish. All cabinets are IP44 rated.
Heat Exchanger: The combustion chamber/
heat exchanger assembly has been designed
to combine optimum thermal efficiency with
extended service life. Manufactured from
304/316 stainless steel each fabricated assembly
comprises of a drum type combustion chamber
coupled to a tubular heat exchanger.
Burner: All oil and gas fired cabinet heaters
have been carefully matched with a fully
automatic packaged pressure jet oil or forced
draught gas burner. Oil fired cabinet heaters
are complete with factory fitted fire valve
and oil filter. Models 1200 and 1300 oil and
1300 gas are fitted as standard with high/low
burners. High/low and modulating gas burners
are available as an option for models 200 and
above.
Efficiency: Each heater within the range has been
designed and developed with fuel efficiency in mind
and efficiencies exceed the mandatory requirements
of CE legislation. Additionally for the United Kingdom
market all heater efficiencies are compliant with the
needs of Part L2B of the 2006 Building Regulations whilst
most models within the range have also been rated to
meet the criteria necessary for inclusion into the Enhanced
Capital Allowance (ECA) scheme.
Fuel: Oil heaters are design to operate on Class D light
distillate ‘gas oil’ having a maximum viscosity of 4.5 c.St at 20oC
(35 sec Redwood at 100oF). Forced draught gas heaters can be
specified to operate on either natural gas (G20) or Lpg Propane
(G31). Most oil fired models can be operated on kerosene.
Fan: Air movement is provided by either a single or duplex
forward curved blade dynamically balanced centrifugal fan
assembly complete with double inlet rotors. Fans on models
100 - 300 are powered by integral motors whilst all others
employ pulley and belt drive arrangements.
Air Distribution: Air is discharged through a duct outlet
spigot located on the top face of a vertical heater and on the left
hand or right hand end of a horizontal heater.
Generally return air to the heaters is via a duct spigot located
on either the left hand or right hand side of a vertical heater (a
rear located spigot is an option for certain vertical models) or,
for horizontal heaters, return air entry is on the opposite end of
the heater to the duct outlet spigot. However heaters can, as an
option, be fitted with fresh air inlet louvres.
Controls: Benson cabinet heaters are supplied ready for fully
automatic operation and are complete with both safety and
comfort controls. Each heater is fitted with a safety overheat
thermostat as well as a time and temperature control system.
Two alternative control options are available.
As standard, heaters are offered with a digital time switch,
mechanical day temperature and frost protection thermostats.
Alternatively heaters may be specified with an optimised control
that includes a secure entry code facility, an optimised digital time
switch with override facility, electronic day thermostat and frost
protection thermostat.
Unless otherwise specified the controls for both vertical and
horizontal external heaters are housed within a console for
remote mounting. Inter-connecting wiring between heater and
remote consoles is by others.
All heaters have the facility of ‘fan only’ operation for summer
air movement.
Testing, Approvals & Certification: Benson Heating
is accredited with ISO 9001 quality assurance certification
– certificate number FM14923. All gas fired heaters have been
type tested by an independent notified body and conform to
CE requirements. Each heater is inspected and test fired prior
to despatch.
Guarantee: Benson cabinet heaters are provided with a
comprehensive package of guarantees covering both the
appliance and the combustion chamber/heat exchanger, which
has the further benefit of an extended guarantee. For sales
within the United Kingdom the guarantee includes a ‘whole
appliance’ twelve months parts and labour guarantee supported
by a further twelve months ‘parts only’ guarantee whilst the
combustion chamber/heat exchanger assembly has a ten year
time related warranty. For cabinet heaters supplied to overseas
markets please refer to the relevant country documentation. All
guarantees are subject to terms and conditions.

Note
Where heaters are selected for the UK Enhanced Capital Allowance (ECA)
scheme then they must be specified with CP4 controllers
All models have efficiency levels which meet with the minimum efficiency
requirements of UK Part L2B Building Regulations
Air handling data is assessed at room ambient conditions
Overall heater height excludes flue and cowl - for more detailed dimensions
refer to dimensions page
Overall dimensions model EHD include base frame.
Noise levels are for units with both inlet and outlet ductwork attached and
measured 3m from appliance
Installation
Installation Standards: Benson oil and gas fired external cabinet
heaters must be installed and commissioned by a competent person
and in accordance with Benson’s installation and commissioning
instructions, relevant local and national standards, Codes of Practice,
and any requirements of Local Authorities, Fire Officer or insurers.
Air Supply: External cabinet heaters are designed specifically
for outdoor location and as such obtain necessary combustion air
directly from an external source. Care should be taken to ensure
that the combustion air inlet louvre or combustion air duct (if fitted)
is not modified, repositioned, damaged or in anyway restricted.
Siting: The position chosen for the heater will need to take account
Flues: External cabinet heaters are supplied complete with a flue kit
of the following points External cabinet heaters are specifically designed for external
location and must be positioned on a flat, level and noncombustible surface. Care should always be taken to ensure
that any base, platform or structural steelwork supporting
the heater is structurally adequate and that there is both
access and provision for maintenance purposes.
Care should be taken to ensure that the recommended
clearances are maintained and that there is sufficient
space for the connection of discharge and/or
return ductwork or, if fitted, that there is sufficient
clearance for the passage of air to the fresh air inlet
weather louvre.
Consideration should be given to the location
of the appliance so that the flue exit point does
not discharge exhaust gases beneath or adjacent
to doors, windows, building overhangs or in
passageways.
So far as controls are concerned siting will often
depend upon the type selected. Where controls
have in-built or remote temperature sensors then
consideration should be given to ensure that the
sensor is located in a position which adequately
reflects the working zone serviced by the heater.
Sensors should not be located in areas subject to
cold draughts.
In case of doubt relating to any aspect of heater or
control siting please consult with Benson.
Oil & Gas Pipework: The oil and gas supply
pipework should be sized and installed with due regard
to all relevant standards and legislation, flow rates and the
maximum/minimum inlet pressure requirements of both oil
and gas fired heaters. Isolating gas cocks, oil line gate valves and
service unions should be provided for each heater.
which permits the free discharge of flue gases directly to atmosphere.
For particular applications it may be possible to extend the flue to
enable the point of discharge to be repositioned. However should
this be necessary then the diameter of flue must not be less than
stated in the data sections of this brochure.
In the event that it is necessary to extend the flue then the route and
exit point needs to be selected carefully and it is recommended that
the installer consult the installation and commissioning instructions or
Benson before commencing installation.
Further Information: The foregoing is given for guidance
purposes. More detailed information can be found within the
relevant installation, commissioning and servicing instructions or
alternatively contact Benson.
