INSTALLATION INFORMATION

THE INSTALLATION INSTRUCTIONS CONTAINED HEREIN ARE FOR THE USE OF 
QUALIFIED INSTALLATION AND SERVICE PERSONNEL ONLY.  INSTALLATION OR 
SERVICE BY OTHER THAN QUALIFIED PERSONNEL MAY RESULT IN DAMAGE TO THE 
OVEN AND/OR INJURY TO THE OPERATOR.

Quali

fi

 ed installation personnel are individuals, a 

fi

 rm, a corporation, or a company which either 

in person or through a representative are engaged in and responsible for:
1.  The installation or replacement of gas piping and the connection, installation, repair, or 

servicing of equipment.

2.  The installation of electrical wiring from the electric meter, main control box, or service outlet 

to the electric appliance.

Quali

fi

 ed installation personnel must be experienced in such work, familiar with all precautions 

required, and have complied with all requirements of state or local authorities having 
jurisdiction.

LOCATION

The well-planned and proper placement of your oven will result in long-term operator convenience 
and satisfactory performance. 

NOTE: 

 On gas conveyor ovens, routine servicing can usually be accomplished within the limited 

movement provided by the gas hose restraint.  If the oven needs to be moved further from the 
wall, the gas must 

fi

 rst be turned off and disconnected from the oven before removing the restraint.  

Reconnect the restraint after the oven has been returned to its regular position.

It is essential that an adequate air supply to the oven be maintained to provide a suf

fi

 cient 

fl

 ow 

of combustion and ventilation air.  Follow these guidelines:
1.  Place the oven in an area that is free of drafts.
2.  Keep the oven area free and clear of all combustibles such as paper, cardboard, 

fl

 ammable 

liquids, and solvents.  Oven should only be used on Non-Combustible Floors.

3.  Do not place the oven on a curb base or seal to a wall.  This will restrict the 

fl

 ow of air and 

prevent proper ventilation to the blower motors.  This condition must be corrected to prevent 
permanent damage to the oven.

4.  On all models, tripping of the blower motor's thermal overload device indicates an excessive 

ambient temperature at the back of the oven.  This condition must be corrected to avoid 
permanent damage to the oven.

GAS SUPPLY RATING AND SIZING

Calculations for pipe sizing must take into account the maximum usage rate of all other appliances 
in the kitchen or one or more of the appliances will suffer from inadequate or dangerous 
performance.  The 3/4" NPT connection for the oven is generously sized for use in the control 
box of the oven.  However, unless the oven installation is within 10 feet of the main building gas 
supply, the supply must be larger.  For each oven, a 3/4" NPT 

fl

 exible quick connect hose and 

full port gas shut-off valve is recommended as a MINIMUM.  The main pipe supplying each oven 
branch may need to be larger depending on the number of appliances serviced, the number 
of elbows in the piping, and the pressure.  This should be sized and installed by a professional 
familiar with any local codes that may also affect the installation.

ACCESS CONSIDERATIONS

Locating the gas valve(s), quick connect hose(s) and electrical outlet(s) at the control box end 
of the oven will allow easier access for any service visits.  This improved access should make 
any necessary service quicker resulting in less kitchen disruption.  It will also allow easier 
disconnection of electricity, gas, and restraints for cleaning around and behind the oven.
