•
Heaters have efficiency levels which meet with the minimum
heater efficiency requirements of UK Part L Building Regulations.
•
LNVx heaters comply with the seasonal efficiency and NOx
limits requirements of the Ecodesign regulation (EU) 2015/1188,
Directive 2009/125/EC – Lot 21 Tier 1
•
Standard heaters configured as High/Low. Optional modulation
available.
•
Air handling data is assessed at room ambient conditions
•
Throw figures provide the distance to the point where the terminal
velocity degrades to 0.25m/s
•
Dimensions, weights and clearance data in the table above refer
to LNVx F units only - for data on all other models refer to the
dimensions page and/or the installation instructions.
•
Noise levels are applicable to standard LNVx F and LNVx V models
and are measured 5m from appliance in a free field.
•
Motor kW, run and start amps apply to standard electrical supply as
stated. For optional data contact sales office.
•
Optional 3 phase direct drive centrifugal blowers shown in italics
within brackets().
•
Connection of combustion air duct is not required for ‘flue only’
applications.
•
It is the responsibility of the installing contractor to ensure that
ductwork is correctly sized and balanced when installing LNVx
Centrifugal units.
