LTL Controls CO2 Generator 8-Burner Natural Gas (Low Altitude)

This low altitude model is designed for installations at elevations between 0 and 3,500 feet — which covers most growers in coastal, valley, and mid-elevation regions. If your facility is located above 3,500 feet, you'll need the high altitude version, which is calibrated for the lower ambient air pressure at higher elevations to ensure complete combustion and proper CO2 output. Using the wrong altitude version will result in inefficient burner performance.

A CO2 controller or timer is strongly recommended, though not included in the kit. Running a CO2 generator without automated control makes it difficult to maintain target CO2 levels — the generator will produce CO2 continuously if left on, which can push concentrations beyond the optimal 1200–1500 ppm range and waste fuel. A controller with a CO2 sensor automates on/off cycling to hold your target concentration accurately.

CO2 is heavier than air and will settle downward toward the canopy, so the generator should be mounted above the plant canopy using the included hanging chains and ceiling hooks — typically near the center of the grow room for the most even distribution. Avoid positioning it directly over plants where heat from the burners could cause stress. Ensure adequate clearance from flammable materials and sufficient room ventilation to prevent CO2 buildup beyond safe operating levels when the lights are off.

Yes — CO2 enrichment is most effective in a sealed or semi-sealed environment where enriched air isn't constantly exhausted outside. A fully sealed room paired with CO2 enrichment, air conditioning, and a dehumidifier gives you the most control over your environment and the best return from CO2 investment. Ensure your CO2 controller is programmed to shut off the generator when lights go out, as plants only consume CO2 during the light cycle.

Yes. LTL Controls offers this same 8-burner generator in a propane configuration for growers without access to a natural gas supply. Depending on your canopy size, you might also consider the LTL Controls CO2 Generator 4-Burner Propane (Low Altitude) or the high-capacity 10-burner propane model. Do not attempt to run a natural gas generator on propane or vice versa — the regulator and burner orifices are calibrated for a specific fuel type.

Always ensure your grow room has adequate airflow and that CO2 levels are monitored with a dedicated controller or monitor — CO2 concentrations above 5,000 ppm are hazardous to humans. Never run the generator with the room sealed and no monitoring in place, and always shut it off before entering the space if you have any concern about CO2 accumulation. Mount the unit securely using the included hardware, keep it away from flammable materials, and follow all installation instructions included with the kit.
