What is the acceptable breach draft range?

The acceptable breach draft range is vital for ensuring the efficient operation of heating equipment, particularly oil burners. The correct range, which falls at -0.3 to -0.7, indicates the ideal negative pressure level necessary to ensure proper combustion and safe operation.

This range helps to balance the air-to-fuel mixture, thereby promoting complete combustion and minimizing emissions. If the breach draft is within this range, it suggests that the flue gas is being effectively vented, reducing the likelihood of backdrafts or the accumulation of harmful gases in the living space. It also ensures optimal heating performance, as improper draft conditions can lead to inefficiencies and potential safety hazards.

Understanding this range is crucial not just for compliance with safety regulations but also for the maintenance of equipment performance, helping to reduce fuel costs and enhance the longevity of the heating systems.
