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”.
š Electrical access panels must not be opened
unless the main supply to the oven is
isolated.
š All connections must be made in accordance
with the regulations of the country where the
oven is installed.
The convection oven is made of stainless steel
and is fitted with a removable tray rack, allowing
easy cleaning of its internal surfaces.
š Do not touch the oven, its windows, or
immediate surroundings during or shortly
after use, as these surfaces may be hot.
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.
š Use only Belshaw parts in this oven.
š Do not change the construction of this oven.
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.
š 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.
The high-speed fan and ring element provides
efficient air circulation, helping produce a range
of high-quality products.
š This oven uses a steam generator. Hard
water must be properly treated before use.
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.
To use the convection oven safely, heed the
following warnings and all other warnings that
appear in this manual.
š Use the oven only for baking bread,
confectionery, and savory products. Do not
use for any other items without consulting
Belshaw.
š All repairs and maintenance of electrical
units must be done by authorized electricians.

š ¾” BSP female thread on the oven.
š 3 foot-long hose with ¾” B.S.P. female
fittings at both ends (included)
š Inline backflow valve (customer must
provide and fit)
š 15-60 p.s.i. water pressure

The BX oven should be connected to a local
means of isolation.
š To stop the oven in an emergency, switch off
at the wall isolator.
