It is similar to Bunsen burner. It is used for high temperature burning.
Unless you want to limit the heat, it should be placed within a few centimeters of the flame, because the heat dissipates pretty quickly if the heated object is any higher.
Either the fan is set at too high a speed or the burner did not light.
Mostly because of high winds, low soil moisture, and cold temperatures.
I am going to ignore your poor grammar skills on this one, but here is the answer. You first start on a low power to locate the specimen or bacteria. Then you switch to a high power to get a better look at it. Hope this helps.
The furnace high limit switch is typically located near the heat exchanger or burner chamber of the furnace.
Aquastats are thermostats sensing the temperature of the water itself, and are used basically to stop and start the burner by controlling the electrical circuit. The temperature of the water is held within preset limits by the aquastats. As the temperature of the water drops to the low setting, the aquastat closes a contact and starts the burner. When the temperature reaches the high setting, the aquastat opens the contact and stops the burner. There is usually a high limit setting which will open the contact, if it should fail to open on the automatic HI/LO control. This feature can be contained within the same instrument or it might be a separate unit. What temperature should the aquastat be set at for the boiler?
The purpose of the high limit switch in a furnace is to monitor the temperature inside the furnace. If the temperature exceeds a safe level, the switch shuts off the burner to prevent overheating and potential damage. This helps ensure the safety and efficiency of the heating system by preventing fires and protecting the components from excessive heat.
To test the high limit switch in your appliance, you can use a multimeter to check for continuity. First, disconnect the power to the appliance. Then, locate the high limit switch and remove it from the appliance. Set your multimeter to the continuity setting and place the probes on the terminals of the switch. If the switch is working properly, the multimeter should show continuity. If there is no continuity, the switch may be faulty and need to be replaced.
The furnace high limit switch may keep tripping due to overheating caused by restricted airflow, dirty filters, malfunctioning blower motor, or a faulty high limit switch itself. Regular maintenance and inspection can help prevent this issue.

A limit switch on a furnace is a safety device that monitors the temperature inside the furnace. If the temperature gets too high, the limit switch will shut off the furnace to prevent overheating and potential damage.
When a typical residential furnace or gas package unit "high limit switch" is found to be bad it is replaced with a new one-not repaired.
This is a switch designated to stop a peice of equipment before it does damage to itself or the surroundings.
The thermocouple only keeps the pilot light. Temp sensor,gas valve, high limit switch, safety switch,thermostat, would cause burner not to stay lite. Better to post MFG,model, problem. lenox,model #, ______________________________
Spa not getting to temp? Could be a dirty filter. Could be a high limit switch or other component.
