What is the maximum length of a flue pipe for oil-fired power burner appliances without a draft inducer?

The maximum length of a flue pipe for oil-fired power burner appliances without a draft inducer is 10 feet. This specification is crucial to ensure proper venting of combustion gases and to maintain efficient operation of the burner. A flue pipe that is too long can lead to insufficient draft, which may result in incomplete combustion, poor appliance performance, increased emissions, and potential safety hazards.

In situations where the flue pipe exceeds this length without a draft inducer, the risk of backdrafting and the accumulation of harmful gases increases, which is why adherence to the 10-foot limit is important. Proper venting practices not only enhance performance but also comply with safety standards set for oil-fired appliances, ensuring that they operate safely and efficiently.
