CO2 (carbon dioxide) is needed by plants for proper growth. CO2 can be
added by burning propane or natural gas - cheaper and easier to obtain
than bottled CO2. The Gas Pro uses faster, more reliable, more
efficient, electronic spark ignition. When the Gas Pro is turned on,
spark and pilot gas start. When the pilot is lit, spark stops and main
gas turns on and is lit by pilot. When the Gas Pro turns off, all gas
turns off. Spark is better than standing/continuous pilot because they
must be manually lit, burn all the time, and waste gas. Spark is faster
and more reliable than a glow plug - no time needed for glow plug to
heat up, spark ignites immediately. Both Propane and Natural Gas models
available. Each have two sizes - a six burner and a twelve burner. The
Propane model includes a regulator for connection to a propane tank.
Gas hose (20 ft.) included with all models. Strong 18 gage steel
enclosure - powder coated for heat and rust resistance. Heat exchanger
allows forced air cooling if desired.
Plug
the 120V power supply (included) into a controller or timer.
Alternatively, the Gas Pro allows easy connection of a CO2-400
controller. Just plug CO2-400 's 10 ft. cable into connector on the
side of Gas Pro. Extension cable available. No separate power supply
needed - it draws power from the Gas Pro. The CO2-400 has a display and
buttons for showing present PPM and setting desired PPM level.
