Modifying CO
Output
2
It is strongly recommended to use a controller or timing device to properly manage the output of the Generator. If this is
not possible, the Generator's CO
number of active burners. Additional plugs may be purchased separately. The Specifications table shows the size of the
growing area that is appropriate for each model as well as how much CO
Each burner replaced with a brass pipe plug will reduce the Generator's output by 2.65 cu ft/hr of CO
a standard liquid propane unit, 2.7 cu ft/hr of CO
1,788 BTU for a high altitude liquid propane unit, and 2.4 cu ft/hr of CO
The CGLP-10 and CGNG-10 feature the ability to vary CO
the two burners nearest the electrodes, and two additional selector switches independently activate two separate banks
of four burners each. Brass pipe plugs are also provided for further modification. To determine the appropriate number of
burners to activate for the growing area, divide the size of the growing area (in cubic feet) by 1,000. For example: Activate
six burners in a growing area of 6,000 cu ft.
Electronic Ignition Control Module
The Generator's electronic ignition control module produces a spark that lights the burners, eliminating the need for an open
pilot flame and providing consistent, controlled starts. The module controls dual redundant solenoid valves.
High Altitude Generators
High Altitude Generators are specially designed to operate and compensate for reduced oxygen levels at altitudes higher
than 4,500 ft above sea level. BTU and CO
(see Specifications table).
A High Altitude Generator may be operated at altitudes as low as 2,500 ft above sea level, but the unit should be tested
before use to ensure all burners ignite correctly and consistently.
FAQ
• I smell gas around the generator, is that normal?
No. Turn off the gas supply immediately. Do not turn on any electrical devices. Ventilate the area and leave until the gas smell
dissipates. Turn the gas supply back on, then determine where the leak is by spraying soapy water on the gas connections. Retighten
the connections where bubbles appear.
• What does a flashing "Lock Out Error" LED mean?
The gas supply may have been interrupted. "Lock Out" is a safety feature activated when the pilot does not ignite after five attempts.
When the problem has been fixed, reset the "Lock Out" by turning the power off for 30 seconds and then back on. The unit will reset
automatically after 20 minutes and attempt to ignite the burners.
• Should the Generator produce buzzing or sparking noises?
The Generator will produce buzzing or sparking noises only when the unit is attempting to ignite the burners.
• What should the flames look like?
The flames should burn clean and blue, resembling a flower or star. Do not operate the generator if the flame is yellow, excessively
large, or weak and lazy.
• Does it matter which burners are replaced with the pipe plug?
The burner nearest the electrodes must remain in place. Remove and replace burners starting with the burner farthest away from
the electrodes.
Troubleshooting
• Why isn't the Generator working and why aren't the LEDs illuminating even though the power is connected?
The tip-over switch may have been triggered. To reset, tilt the unit to the side and listen for a clicking noise. Ensure the unit is level to
avoid triggering the switch.
• Why won't the burners ignite even though the unit is attempting to ignite them?
Verify the unit is generating a spark and the burner closest to the electrodes is active. Ensure there are no kinks or twists in the gas
line and the gas supply is adequate. Turn off the gas regulator for 30 seconds, then try again.
• Why isn't the CO
level increasing to the desired ppm?

Check for air leakage in the growing area. Do not operate exhaust fans while CO
• What if the growing area gets too humid or hot?
Reduce the settings on the controller or timing device. If an output control is not being used, burners can be removed and replaced
with the provided brass pipe plugs.
