What must be checked regularly for a waste oil burner?

Regularly checking the flue gas temperature in a waste oil burner is crucial for several reasons. First and foremost, maintaining the proper flue gas temperature can help ensure efficient combustion. If the temperature is too low, it may indicate incomplete combustion, leading to increased emissions and potential soot build-up. Conversely, if the temperature is too high, it could pose a risk of overheating and damage to the system.

Monitoring the flue gas temperature also provides insights into the overall performance of the burner. A stable and appropriate temperature range is necessary for optimal operation and to ensure that the burner is functioning within the manufacturer's specifications. This helps to minimize issues related to inefficiency and can prevent potential system failures.

While checking oil viscosity, water levels, and electrical connections are also important maintenance tasks, they are not as critical to the immediate operation and efficiency of a waste oil burner as keeping track of flue gas temperature. Proper temperature management takes precedence in ensuring that the burner operates safely, efficiently, and effectively.
