Frequently Asked Questions
The problem will be with the thermocouple, which is attached to the back of the flame valve. The tip of the thermocouple is in the heat, and when the brooder is lit the tip heats up and generates a small electrical current that energizes the electromagnet inside the flame failure valve. Using an 8 mm spanner on the nut, unscrew the thermocouple from the flame failure valve, remove it from the brooder and replace it.
The electromagnet inside the flame failure valve has become faulty and needs replacing. This is a gas tight joint and therefore after you have replaced the electromagnet the joint must be checked with soapy water. Bubbles mean a leak - if you see bubbles remake the joint using a gas approved sealant.
The ceramic is either cracked or has moved on its gasket. If the ceramic has cracked it will need to be replaced. If the ceramic is not cracked and has simply moved on its gasket, it needs to be re-seated on the fibre gasket. Ensure that the steel springs are in place and retighten the 4 screws using an 8 mm spanner.
The regulator is faulty. It has probably been polluted with heavy-ends which is the name given to the muck that accumulates in gas cylinders over time and can build up in the regulator causing it to fail. The regulator needs to be replaced. Check the pressure specification which will be stated on the data plate on the brooder. Ensure that the replacement regulator is of the correct pressure rating.
The gas and air are not mixing correctly. The cause could simply be dust in which case the filter needs to be cleaned and the brooder blown through with an air line. If the problem persists the next step is to check the jet, which may be partially blocked. Jets can be cleaned but never picked out. The easy way to clean a jet is to remove it from the brooder using an 8 mm spanner and place the jet into a bottle with a little white spirit or cola drink. Shake the bottle well, remove the jet from the liquid and blow it out with an air line. Note that it is important to blow back towards the threaded end. Replace the jet. DO NOT OVER TIGHTEN. Check for leaks using soapy water. Bubbles mean a leak - if you see bubbles remake the joint using a gas approved sealant. Retest the brooder. If the problem persists the regulator needs to be replaced. Check the pressure specification which will be stated on the data plate on the brooder. Ensure that the replacement regulator is of the correct pressure rating.
