Actually, two types of CO2 generators are offered. The first type is conventional. The second, being the most interesting to the indoor gardening amateurs, features a heat exchanger removing up to 30% of the heat produced in excess by the gas combustion, to limit the effect of high temperature on plants growing in closed environments. While removing excess heat through a set of ducts, the LP4X and LP8X carbon dioxide generators do not affect the actual CO2 concentration, as none is vented out if the piping is air tight..Carbon dioxide high concentration in a closed gardening environment is scientifically known to be beneficial to growing plants in terms of accelerated growth and maximum yields. Better results are obtained when the closed growing environment or room climate parameters are properly controlled, to keep the plants' stomas opened, both day and night. Separate sets of temperature, relative humidity and CO2, for day and night, are required by plants in order to attain swift maximum yields.   Features Safety panels surfaces to avoid burning at the touch Safe, easy to use and highly energy efficient Safe electronic pilot: no manual starting button nor continuous flame Internal electronic control to avoid excessive heating and to turn off the unit in case of tipping over Heat exchanger helps keep a cooler temperature inside the greenhouse or grow room without affecting the CO2 and humidity levels Connect to heat exchanger 6 inches diameter flexible ventilation tubing to exhaust heat (2 metal sheets adapters included) Heat exchanger may be ducted to supply heat to living space (fan suggested) without introducing CO2 D: 16.5” —H: 20.5” —W: 9.5”   USEFUL TIPS:  Plug CO2 generator sense cord to a CO2 controller like iGS-061, iGS-100 or iGS-220 to control CO2 concentration in your grow room or greenhouse.  To control many CO2 generators with the same controller, you can chain link up to 5 burners by plugging the sense cord of the next burner in the outlet of the previous one   Cool this generator by drawing air from outside through the sealed heat exchanger without venting out the CO2!
