VEVOR CO2 Generator User Manual

Summary

CO2 generators have main uses in plant vegetables, increasing the CO2 content for vegetable and flower planting in greenhouses. W8B is a safe and economical solution to produce CO2 by burning propane, natural gas, or methane. It has some characteristics: high yield, safety, convenient operation, and low cost. It is an ideal greenhouse product for accelerating plant growth, increasing yield, improving quality, and enhancing disease resistance.

This 8-burner CO2 generator can produce 16-26 cubic feet per hour. The W8B is recommended for areas over 3200 cubic feet.

NOTE: An air exchange is recommended when using CO2 generators. At least once every hour to avoid your plants from getting CO2 poisoning.

The W8B used an automatic electronic ignition module. When ignited unsuccessfully, the solenoid valve can automatically prevent the gas from leaking out in the event. A standard tip-over switch is one of the safety features of the W8B.

Also, comes standard with 8 brass burners and a 12-foot hose. A regulator is provided to connect or tap into existing lines.

WARNING: Not recommended for use inside a Grow tent. The high heat can cause the melting of the wall material.

Installation

• Determine the desired location for the W8B. It must be mounted at least 18” away from walls or any flammable material. An 18” clearance must be maintained between the unit and the ceiling (18” of chain provided with W8B). Open flames are present inside the unit. Do not use the unit around flammable materials. The unit does get warm to the touch.
• The W8B must be hung correctly for optimum operation. Use the hooks & chains provided with the unit to secure to the ceiling. The unit must be level to operate correctly and safely. Tighten all slotted brass caps by hand, as they may come loose during shipping.
• The hose provided is fitted with a standard 3/8” female flare connector. Connect the hose to the back of the W8B. Use two crescent wrenches or similar to tighten the connection properly. This should be done without twisting any other connections.

WARNING: Connecting the W8B LP unit to a Natural Gas line will result in huge flames. Alternatively, if a W8B-NG is hooked up to propane, this will result in very low and insufficient flames. Make sure your fuel matches the Generator type.

Propane Generator Only

NOTE: The W8B-LP has a standard tank-mounted regulator, which should be used unless the incoming pressure is already regulated to 11” WC (water column).

• Connect the other end of the hose to the brass connector on the LP regulator provided. Use the two wrenches again, one to hold the regulator from the bottom side. The other is to twist the 3/8” brass connector on tightly.
• Open the valve on the propane tank or a bigger fuel source. Check the Lines and connections for leaks by spraying them with soapy water from a spray bottle. Look for constant bubbling, which would indicate a leak. Fix the leak and repeat the process.
• Flip the power switch to the on position within 20 seconds. unit will begin to spark to ignite the fuel.

Natural Gas Generators Only

NOTE: Installing the regulator “in-line” between your gas supply and generator is essential. The regulator supplied with the W8B-NG is present to maintain a constant pressure of 4.5” WC, which is around ¼ PSI. Before installation, verify your main gas pressure.
Most Gas companies install low-pressure gas regulators at the meter that are about ½ PSI. Some commercial buildings have a high-pressure gas main (usually around 2 PSI). If the pressure is high, it will need to be reduced to ½ PSI or lower before installing the regulator (high pressure can keep the valves open, causing unit to run with no power).

• When installing, install a gas shut-off valve on your line (turn off at the main or meter). Install the shut-off valve in an accessible location. Install the in-line regulator to the gas supply (3/8” NPT female thread). Connect the hose to the flared fitting on the regulator. Using two crescent wrenches or similar to tighten connections.
• Open the inline shut-off valve (ensure the main is on). Check for leaks using soapy water and a spray bottle. Look for bubbling; this indicates a leak.
• Flip the power switch to the on position, within 20 sec. unit will begin to spark to ignite the fuel.

Connecting to the CO2 controller

NOTE: The recommended CO2 level for optimum growth is between 1000 to 1500 PPM. Above these levels is considered wasteful. Above 5000 PPM is considered dangerous to animals and humans. Side effects of excessive CO2 include headache, drowsiness & shortness of breath. Use a PPM controller to ensure you’re maintaining proper PPM levels.

• Connect the CO2 generator’s power supply to the controller that you are using. The generator should be used during light-on hours. At the bare minimum, a timer can be used to turn the generator on/off. Possibilities are likely to exceed the recommended PPM range with this method.
• Set the CO2 controller to the desired PPM level and plug in the power of the CO2 generator into the controller.

Lighting the Generator

• Connect the power supply to the power connection on the side of the generator and plug it into the wall or your CO2 controller.

NOTE: Confirm that the supply voltage and plug voltage is the same.

• Ensure the power switch on the side of the unit is OFF. Turn on the gas supply to the unit.
• Turn on the power switch. The generator will turn on the valve and attempt to light the generator. It will make 5 attempts to light the main burner, 20 seconds apart. If the generator does not light on the 5th attempt, a red light will appear on the electric ignition module indicating that it could not light in 5th attempts. And give an alarm. It will not try again until the power is cycled. Turn off the power switch and turn it back on, it should light with the next 5 attempts after all the air in the gas line is gone. Depending on the length of the gas hose, you might need to turn it on and off to 3 or 4 times. If your generator still will not light, please refer to the troubleshooting tips at the end of this instruction manual.
• Once the main burner lights, it should light reliably until the tank (propane only) is changed out.
• The red indicator light on the side of the generator and the blue light on the ignition module is both on as long as the main burner is running.

Proper Sizing

Considering that some manufacturers have inaccuracies within their generator ratings is essential. A straightforward conversion can be used to compare sizes to determine a CO2 generator’s capacity to produce CO2. That is assuming you know the actual Btu output of the unit. British thermal units (BTUs) are the unit’s actual heat output.

Heat output (BTU), is determined simply by knowing the gas pressure, the type of gas (LP or natural), and the volume of gas allowed to flow to the burner.

So, a CO2 generator running propane, with a rating of 22,352 Btu, will produce 26.4 cubic feet of CO2 per hour, assuming a standard pressure of 11” WP is used. A natural gas-fired generator rated 25,080 will produce up to 25 cubic feet per hour. That’s not the only thing to consider.

Reducing Burners

The W8B CO2 generator has eight burners; you can reduce them as needed. The front panel can be removed.

Four screws are used to secure the panel in place. Loosen the screws and lift the panel off the keyhole to expose the burner assembly. Be sure to replace the cover before operating.

CO2 Generator Troubleshooting

If you are having problems with this unit, refer to these troubleshooting hints.

The generator does not light.

1. There could be air in the gas line, especially when changing propane tanks or turning on your generator for the first time. Turn generator off and turn it back on. Let it attempt to light 5 times and then repeat.
2. If the generator lights the main burner and then immediately turns back off, the flame sensor may not be directly in line of the flame. Tighten up the slotted jet caps on both sides of the spark ignitor/flame sensor so that the fire coming out of the burner is aimed at the spark ignitor/flame sensor. Bend the mounting bracket slightly to adjust the flame sensor to be in the flame’s heat.
3. Make sure that the tank is full and that the gas is turned on.
4. Verify that the unit matches the type of gas you are supplying and that the gas pressure is correct.

The flame on the main burner seems either too large with a yellow flame or too small, “flashing” ON and Off

1. You may have mixed burners. Verify you are using a natural gas burner with natural gas and a propane burner with propane.
2. A lazy yellow flame indicates low gas flow due to low propane tank levels or natural gas pressure. Long piping runs with natural gas need to be appropriately sized.
3. Verify the unit matches the type of gas you are supplying and the gas pressure is correct.

The unit is plugged in and turned on, but the burner doesn’t work

1. Verify the power switch is ON and the power supply is getting power.
2. Make sure the unit is level. If the unit is tilted more than 35 degrees in any direction, the unit can’t operate.

NOTE

• ALWAYS check for leaks using soapy water and a spray bottle after making the gas connections.
• This unit is not for residential use. The exterior of the unit can get very HOT when in operation.
• Always wait for the generator to cool down before servicing or removing the front panel.
• Do not operate the unit with the front panel removed.
• When the unit stops using or depositing in the room, it should turn off the power and gas source.
• When not used for long, separate the CO2 generator and gas source.
