1.
Gas appliance classification for approved venting methods are based on EN 1749:2020
2.
Refers to gross calorific value of fuel
3.
Refers to net calorific value of fuel
4.
Propane gas: G31 Hs 95.65 MJ/m³ @ 15°C and 1013.25 mbar
5.
There is a difference between the gas connection diameter and the diameter of the supply line. Always use the most adequate
diameter of the supply line to minimise the pressure drop through the gas pipes. If necessary, reduce the diameter of the supply line
at the inlet of the unit.
6.
Sound pressure measured in dB(A) at 5m distance from the heater with A=160m
2
and Q=2
7.
Minimum height from floor to bottom surface of the heater for safe use of the heater. Positioning of unit heaters for performance is
application dependant. Operation is affected by other air moving equipment in the room space, obstructions to the airflow,
draughts and/or close proximity to doors or windows etc. Care should be taken to avoid mounting the heaters higher than these
recommendations unless downturn nozzle options are used, as significant stratification may occur resulting in poor floor coverage
and higher energy losses through the roof structure. Isothermal cond/- 20°C ambient air temperature, discharge louvres zero
deflection, v=0.5m/s. The airflow will be influenced by the height of the building, mounting height of the unit, ambient temperature
and adjustment of the louvres.
