(1)The category of the exhaust methods for fuel gas fumes can be treated according to the CEN report, CG1749-2001;
(2)The installation height of the fan heater is recommended by the manufacturer and different use and installation requirements vary the planned use of the fan heater. The operation and efficiency of the fan heater are also affected by a number of external factors, such as other air treatment equipment, barriers along the intake path, cross ventilation and the doors and windows of an enclosed building. Efforts will be made to make the installation height of the fan heater exceed the recommended value, unless a downward air distributor is used. Otherwise, indoor air may become stratified, reducing the effective distribution of air and may obviously increase the thermal loss generated by roof structure;
(3)This refers to the place where the ambient air temperature is 20 C, the air distribution shutter is 0 and the air velocity is 0.5m/s under isothermal working conditions;
(4)dB (A) is the value at 5m distance from the fan heater in the reference environment where A=160m2 and Q=2; (5)dB (A) refers to the open space which is 5m from the fan heater;
(6)dB (A) is measured on the basis of 150Pa pressure of air outlet.
