What is recommended for the arrangement of a draft regulator in an oil burning appliance?

The recommended arrangement for a draft regulator in an oil burning appliance emphasizes the importance of proper installation and accessibility based on function. A draft regulator, which helps to maintain the correct airflow through the appliance, is essential for efficient combustion and safe operation.

The correct answer emphasizes that a draft regulator is critical for maintaining the desired draft in the flue system, but if the appliance does not require it due to design or specific operating conditions, then it can be omitted. This scenario reflects cases where certain appliances are engineered to operate optimally without a draft regulator. Therefore, the statement acknowledges that not every oil burning appliance requires a draft regulator, inherently focusing on the appliance design and functionality.

The accessibility for manual adjustment is vital in ensuring that users can make necessary adjustments for optimal performance and efficiency, but this does not mean that a draft regulator would be present in all cases. The considerations of location, installation above the burner, and other alternatives all highlight the importance of ideal conditions for each specific appliance but do not encompass the broader scenario of when a draft regulator might be appropriately excluded altogether from certain systems.
