Water connection

Combi King ovens have one or two water connections.

To facilitate cleaning and service, the oven should be connected with an approved flexible ½” hose and the
permanent installations should be fitted with a stop-tap and a non-return valve. Before connecting the oven
to water, flush the tubes thoroughly. Connect

should be at least 3” (7 cm). This is to ensure the necessary flow of cooling air to the
oven. Strong sources of heat such as hotplates, tilting frying pans, deep fat fryers,
etc. should not be placed near the oven, otherwise the warranty may cease to apply.

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

The ventilation motor can be controlled directly from the oven. This means that
the ventilation starts when a program is started and runs for 10 minutes after the
program is completed.

When the oven

is on (a program or a function has been activated – the square around the function flashes),

it is still possible to set TIME, TEMPERATURE, FAN and EXHAUST.

Note that the fan wheel is reversible. This means that the wheel can run leftwards as well as rightwards with
a small interval

when changing direction.

The core temperature should be set before the program is started.
