Exhaust

The BKI ovens are equipped with an open/direct exhaust system that
removes surplus humidity from the oven chamber. The exhaust system has
an electrically operated damper. The exhaust tube can be connected to a
ventilating system. In that case, a special extraction funnel is fitted to avoid
suction directly from
ordered from BKI. The scope of supply also includes a specially designed
extraction hood, see adjacent illustration.

If an extraction hood is installed in the ceiling above the oven, it should project
20” (50 cm) over the front of the oven. The suction
