Preface  
The Belshaw BX Smartbake 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 Any chimneys or ducts fitted above the ovens  
The convection oven is made of stainless steel  
and is fitted with a removable tray rack, allowing  
easy cleaning of its internal surfaces.  
should be insulated.  
š All connections must be made in accordance  
with the regulations of the country where the  
oven is installed.  
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 Do not touch the oven, its windows, or  
immediate surroundings during or shortly  
after use, as these surfaces may be hot.  
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 Use only Belshaw parts in this oven.  
š Do not change the construction of this oven.  
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.  
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.  
š 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.  
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.

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.  
š The BX Smartbake 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.  
WARNING  
š For stacked ovens, the water supply should  
be shut off by closing the shut-off valves.  
(See Figure 1-1)  
Do not allow water to enter the control  
panel or rear access panel.  
š For non-stacked ovens, the water supply  
should be shut off at the nearest shut-off  
point.  
The BX Smartbake oven needs the following for  
the water supply:  
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  
Installation  
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.
