ADDENDUM : TECHNICAL DATA
(1) Gas appliance classifi cations for approved venting methods based on CEN-report CR1749:2001
(2) There is a difference between the gas connection and the pipe size of the supply line. Always use the most suitable pipe size to
minimize the pressure drop through the gas pipes - if necessary, reduce the pipe size of the supply line at the inlet of the unit.
(3) Figure for isothermal conditions.
(4) Height from fl oor to bottom surface of heater. These are recommendations only positioning of unit heaters for proper performance
is application dependent Operation is affected by other air moving equipment in the space, obstructions to the airfl ow, draughts
and/or close proximity to doors or windows, etc… Care should taken to avoid mounting the heaters above these recommendations,
unless downturn nozzle options are used, as signifi cant stratifi cation may occur resulting in poor fl oor coverage and higher energy
losses through the roof structure.
(5) Isothermal conditions at 20°C ambient air temperature, discharge louvre zero defl ection, v = 0,5 m/s. The air throw will be infl u-
enced by the height of the building, mounting height of the unit, ambient temperature & adjustment of the louvres.
(6) Sound pressure level in dB(A) in free fi eld conditions, measured at 5 meters from the unit
(7) Sound pressure level in dB(A), measured at 5 metres from the unit with A=160m² and Q=2
(8) Measured at nominal input rate with G20 at 20°C ambient
