NOTICE: 

This Owner’s Operating and Installation Manual should be 

given to the user. The operator of the oven should be 

familiar with the function and operation of the oven. 
This manual must be kept in a prominent, easily reachable 

location near the oven. 
Ovens are shipped from the factory configured for use with 

Natural gas. If permitted by local, national,  and 

international codes, at the time of installation the oven may 

be converted to Propane gas operation. This conversion 

requires the use of a Gas Conversion Kit that is supplied 

with the oven. 
For CE-approved ovens, the conversion is described in the 

Installation section of this manual. 
For domestic and standard export ovens, instructions are 

included in the Gas Conversion Kit. 
Middleby Marshall suggests a service contract with a 

Middleby Authorized Service Agent (ASA).
