System Balancing

Having checked that the oven is correctly vented and that the Flue is correctly
calibrated, in some cases there may be external air pressure differences that can affect
the performance of the oven.
In some instances an imbalance may occur between the space above the oven and the
space below the oven. This may result in air being drawn from within the oven to
compensate for this imbalance.
A direct result of this may be that the flame, or smoke, is being drawn under the oven
causing the flame to behave erratically and the ovens performance deteriorates.
In most cases this is due to two (2) possible causes:
 Insufficient ventilation below the oven
In the case of insufficient ventilation below the oven, refer to Ventilation
Requirement in this manual.
 Excessive draw from above the oven
If there is excessive draw from above the oven, this may result in the ventilation
below the oven being insufficient.
In worst case scenarios it may be required that the base of the oven be sealed
off to prevent any air being drawn from within the oven cavity resulting in the
flame being drawn under the oven.
The following diagrams explains excessive draw from above the oven and the
most common solution to this issue.
