Tube Burner Ventilation

From October 2010, all ovens supplied with a tube burner will also be supplied with a
ventilation kit that should be installed as per the instructions below. This is designed to
eliminate any problems related to poor or insufficient ventilation resulting in the flame
being drawn or "disappearing" under the oven floor.
It is critical that this ventilation tube be installed correctly, and in the correct position,
to eliminate the risk of poor oven performance, erratic flame behaviour or flame failure.
In some instances the ventilation panels both below and above is not sufficient to
overcome excessive air movement from above and around the oven. This is commonly
caused by the ceiling space being used as a return air plenum for the restaurant air
conditioning and ventilation systems.
NEGATIVE PRESSURE
Even though a ventilation panel is fitted below the oven, the negative pressure above
the oven can be greater than the pressure below the oven. Because the tube burner is
installed in the floor of the oven, the hole in the oven floor is a clear passage for air to
flow, thus sucking the flame with it.
