WARNING: Carbon Monoxide is an odorless and poisonous gas. Extended exposure to carbon monoxide
may lead to death. Early signs of carbon monoxide poisoning resemble the flu, including headaches,
dizziness and/or nausea. If you experience these signs, GET FRESH AIR IMMEDIATELY. Have the
brooders serviced as soon as possible and check the ventilation in the house.
The National Fuel Gas Code requires a minimum of 4 CFM per 1000 Btu/hr of brooder input for ventilation.
This requirement means that a total of 120 CFM is required per brooder. Ventilation requirements may vary
depending on other equipment that may be located in the building requiring ventilation. All ventilation
requirements should be addressed before sizing the necessary gravity or mechanical means to accomplish
this ventilation.
While ventilation is necessary for proper brooder operation and proper growing conditions for the stock,
excessive ventilation can result in high fuel consumption. Adjust the ventilation as necessary for optimum
performance of the brooders and growing conditions for the stock.

MAINTENANCE
To keep your brooder in good operating condition, we recommend that after each crop you follow the
maintenance schedule below:
CAUTION: Turn the gas and electric supply (if equipped) OFF and allow the brooder to cool down before
attempting any maintenance.
1. Unscrew the single jet burner tube from the main burner orifice fitting. Remove the main burner orifice
from the fitting and clean the orifice by soaking it in acetone. Refer to Figure 12. Dry the orifice by
blowing compressed air through it. NOTE: DO NOT attempt to clean the orifice by passing a wire through
the orifice as this will increase the orifice hole and result in over firing of the brooder. Apply pipe thread
sealant (resistant to LP Gas) to the threads of the orifice and replace it into the orifice fitting.
2. Clean around the burner ports with a bristle brush (available as an accessory, Part No. 43295010). After
cleaning the burner ports, compressed air can be blown into the burner ports to blow any trash out of the
burner through the burner tube.
3. Remove the pilot burner orifice (No. 2A, 2B, 3 and 9 Models Only) and clean as above for the main burner
orifice. Access to the pilot burner can be made by first sliding the windshield off the pilot assembly.
Next, remove the outer pilot housing from the pilot assembly by pulling the tab with a pair of pliers. After
cleaning, reassemble the pilot in reverse order.
4. Clean the outside surfaces of the ceramic cone with a large wire brush (available as an accessory, Part
No. 43295020); then use compressed air to remove any burnt dust or dirt particles from the cone.
5. Remove and clean the thermocouple (No. 2A, 2B, 3 and 9 Models Only) when necessary.
NOTE:
After reassembly of all components, check the gas connections at the burner and the gas valve for
leaks. Use a heavy soapsuds solution. DO NOT use an open flame to check for gas leaks.
