INSTALLATION
VENTILATION
VENTILATION HOODS
Proper venting along with a sufficient quantity of 
make-up air is essential for proper oven operation.  
A mechanically driven, canopy exhaust hood is 
the preferred method of ventilation and must 
conform to local codes along with the current 
version of NFPA-96 Vapor Removal from Cooking 
Equipment (latest edition). The oven hood must 
extend 6" (152mm) beyond all sides of the oven.  
The distance from the floor to the bottom edge of 
the hood should be between 6' (1829mm) and 
7' (2134mm).
A ventilation hood that supplies make-up air 
down the back vertical wall should be avoided 
since air currents can interfere with the oven 
flue exits. If such installation is unavoidable, an 
additional draft hood, specifically designed to 
deflect downdrafts, must be installed.
DIRECT VENTING
When necessary, direct venting can be used 
in situations where space is limited or to help 
offset the high cost of ventilation hoods.
Direct venting should be installed in 
compliance with local codes by a certified 
professional. In the absence of local codes, 
refer to National Fuel Code NFPA 54, ANSI 
Z223.1 (latest revision).  
DANGER
FAILURE TO VENT THIS APPLIANCE 
PROPERLY MAY BE HAZARDOUS TO 
THE HEALTH OF THE OPERATOR. 
Equipment damage, operational 
problems and unsatisfactory baking 
performance may also be the 
consequence of improper venting. 
Any damage sustained by a failure 
to properly vent this oven are not 
covered under warranty.
DANGER
Installation, air adjustment and/or 
service work must be in accordance 
with all local codes and must be 
performed by a certifi ed service 
technician qualifi ed to work on 
gas appliances. 
Ventilation hoods and exhaust systems shall
be permitted to be used to vent appliances 
installed in commercial applications.
Where automatically operated appliances are 
vented through a ventilation hood or exhaust 
system equipped with a damper or with a power 
means of exhaust, provisions shall be made 
to allow the flow of gas to the main burners 
only when the damper is open to a position 
to properly vent the appliance and when the 
power means of exhaust is in operation. 
IN 
ACCORDANCE  WITH  NFPA  54  COMMONWEALTH  OF
