Cabinet: Low profile in design and robotically punched and formed from electro-zinc plated steel the heater cabinet presents a functional yet pleasing appearance. Access to the burner and controls compartment is via a full width side hinged door. The cabinet is stove hardened epoxy powder coated with a durable Kestrel Grey paint ﬁnish.
Heat Exchanger: Formed from aluminised steel tube into a compact yet highly efﬁ cient four pass ‘S’ shaped assembly the Variante 2 heat exchanger has been designed so that manufacture can be accomplished without the use of any stress nducing welding processes. Stainless steel heat exchanger tubes available as an option.
Burner: Variante 2 family heaters are ﬁtted with a quiet multi-flame low Nox burner which in turn is complete with automatic electronic spark ignition and ionisation flame proving. The burner, in conjunction with the heat exchanger is capable of delivering efﬁciencies in excess of 91% nett.
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 and have been rated to meet the criteria necessary for inclusion into the Enhanced Capital Allowance (ECA) scheme.
Fuel: Heaters can be speciﬁ ed to operate on either natural gas (G20) or Lpg (Propane G31).
Sealed Combustion Circuit: Variante 2heaters are all factory ﬁtted with a power ﬂue venter that enables the heater to be operated in either room sealed or fan assisted ﬂue mode. The ﬂue fan is safety interlocked with the burner control system via a pressure differential sensor.
Air Distribution: Air movement for VRA heaters is via dynamically balanced aerofoil type axial fans which discharge warmth directly into the space to be heated via a set of adjustable horizontal louvres. Heaters for ducted applications, type VRC, are supplied with a centrifugal fan and outlet duct connection spigot.
Controls: Variante 2heaters are complete with necessary safety controls including overheat protection as well as external control connections including ‘fan only’ for summer air movement. Automatic operation requires only the simple connection of time and temperature controls. Benson, as an option, can
provide a number of alternative integrated control consoles with the choice ranging from simple digital/mechanical controls through to fully optimised systems. Benson control systems are for remote mounting with inter-connecting wiring by others.
Testing, Approvals & Certiﬁ cation: Benson Heating is accredited with ISO 9001 quality assurance certiﬁcation – certiﬁcate number FM14923. All gas ﬁ red heaters have been type tested and approved to CE standards by an independent notiﬁed body. Each heater is function tested and ﬁred prior to despatch.

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 heat exchanger assembly has a ten year time related warranty.
