BX Classic Oven MN-1876EN iii

Preface

The Belshaw BX convection oven is a
computerized, compact, electric oven with a
capacity for either four or 10 trays. Each tray is
26” x 18”.

The convection oven is made of stainless steel
and is fitted with a removable tray rack, allowing
easy cleaning of its internal surfaces.

The 4-tray oven is designed to be stackable
without separate support, allowing the system to
grow with your business without taking up a
large area.

The 10-tray oven is equipped with an integral,
energy efficient steam system. A double glazed
door also helps to increase energy efficiency, and
the oven base is supplied with locking castors.

The high-speed fan and ring element provides
efficient air circulation, helping produce a range
of high-quality products.

To help ensure safe and efficient operation of the
oven, the operator must work safely at all times,
read this manual, and follow its instructions and
warnings. A thorough understanding of how to
install, maintain, and safely operate the
convection oven will help prevent production
delays and injuries.

• Electrical access panels must not be opened

unless the main supply to the oven is
isolated.

• All connections must be made in accordance

with the regulations of the country where the
oven is installed.

• Do not touch the oven, its windows, or

immediate surroundings during or shortly
after use, as these surfaces may be hot.

• Use only Belshaw parts in this oven.

• Do not change the construction of this oven.

• The owner of the oven is legally obligated to

instruct staff using the oven in its operation
and in these safety regulations. The
instructions must stay in the oven’s working
area.

• This oven uses a steam generator. Hard

water must be properly treated before use.

To use the convection oven safely, heed the
following warnings and all other warnings that
appear in this manual.

• Use the oven only for baking bread,

confectionery, and savory products. Do not
use for any other items without consulting
Belshaw.

• All repairs and maintenance of electrical

units must be done by authorized electricians.

Water Supply

• The BX oven is fitted with a steam generator.

In areas with hard water, the water supply to
the oven must be treated with an appropriate
protecting water treatment device. It is the
sole responsibility of the customer to provide
and maintain an appropriate water treatment
system.

• For stacked ovens, the water supply should

be shut off by closing the shut-off valves.
(See Figure 1-1)

• For non-stacked ovens, the water supply

should be shut off at the nearest shut-off
point.

The BX oven needs the following for the water
supply:

• ¾” BSP female thread on the oven.

• 3 foot-long hose with ¾” B.S.P. female

fittings at both ends (included)

soapy water and allow the oven to dry
completely.

IMPORTANT

When cleaning the inside of the 4-tray

oven, be careful not to damage the control

probe protruding from the upper corner of

the chamber’s rear wall.

WARNING

Do not allow water to enter the control

panel or rear access panel.

• Inline backflow valve (customer must

provide and fit)

• 15-60 p.s.i. water pressure

Installation

The BX oven should be connected to a local
means of isolation.

• To stop the oven in an emergency, switch off

at the wall isolator.

NOTE

When stacking two BX4 ovens, you MUST

install the Stacking Kit (Part Number

M159-00-00100) between the ovens. Please

refer to Figure 5-1 in Section 5.

"fan cycling disabled."

Note: In a 4-tray oven, the fan is only
functional in an oven wired for 3-phase.
If activated in a 1-phase oven, the fan will
automatically stop.

Note: Programs cannot be saved during a bake
cycle.

Function of Setting

Key 6: Vent Time. This is the number of minutes at

which the vent will wait to open at the end of
the bake cycle. Time can be set from 0-10
minutes.

Note: This time cannot exceed the bake time.

Key 7: Steam Time. This is the amount of time the

steam will inject at the beginning of the bake.
Time can be set from 0-20 seconds.

Note: The oven must be above 257°F (125°C)
before the steam will inject.

Key 8: Bake Time. This is the amount of time the

product will bake. Time can be set from 1-99

instructions must be followed. Failure to comply
with these guidelines may affect the warranty.

• The ambient temperature around the oven

must not exceed 115°F (40°C).

• The ventilation around the oven should be

enough to ensure that there is no
condensation on or around the oven from
