1. Direct sunlight on the unit should be prevented when temperatures are higher than 43ºC. If placed under some kind of protective cover, the cover should not interfere
with the flow of outdoor ventilation.
2. The gas heating units (ARG/ARD) are only appropriate for use with gas. In LPG (Liquefied Petroleum Gas, propane) installations, it must be ensured that in no case
should gasoline in liquid form reach the gas group.
DB: Dry-bulb Thermometer; TH: Wet-bulb thermometer.

(1) LHV: Lower heating value.
(2) Natural gas 2ND-H, G20, at 20 mbar and 15 ºC
(3) Propane gas, G31, at 37 mbar and 15 ºC.
(4) The air flow should be regulated so as to increase temperature within the specified limits. Units with optional high power burners should have a minimum air flow of
10000 m

/h.
Note: The gas units are shipped ready to operate with natural gas. A conversion kit can be used to convert them to propane gas (L.P.G.).
