What occurs if the draft regulator is functioning poorly?

The functionality of the draft regulator is crucial for maintaining the appropriate combustion environment in an oilheat system. If the draft regulator is not functioning as intended, it can lead to an imbalance in airflow, which may cause too much draft to occur over the fire. This excess draft can pull in an increased amount of air into the combustion chamber, leading to incomplete combustion, unburned fuel, and a fluctuation in temperature control.

Excess draft can also contribute to poor fuel efficiency, as more air can cause the system to run hotter than necessary, leading to energy being wasted. Moreover, it increases the operational pressure within the combustion chamber, which can lead to long-term damage and safety issues. In summary, when a draft regulator is working poorly, it typically results in an overabundance of draft over the fire, adversely affecting both performance and safety—making it vital for the draft regulator to function properly to ensure optimal combustion conditions.
