OPERATION INSTRUCTIONS

 

The information in this section is intended for the  use of 
qualified  operating  personnel.  Qualified  Operating 
Personnel  are  those  individuals  who  have  carefully  read 
the  information  contained  in  this  manual,  are  familiar 
with the function of the oven and/or have had experience 
with  operating  the  equipment  described.  We  recommend 
following 

these 

instructions 

to 

insure 

optimum 

performance, long life and trouble-free service from your 
oven. 

The "E" & 6/13 Series of Convection Ovens

 

Convection  cooking  has  been  around  from  the  1960s.  Its 
advantages  are  well  known.  It  differs  from  conventional 
cooking  by  the  movement  of  heated  air  within  the 
cooking cavity by means of a fan. This moving, heated air 
helps  to  strip  the  cool  air  from  around  the  product  being 
cooked,  allowing  the  heat  to  penetrate  more  rapidly.  The 
results  are  that  your  product  is  cooked  quicker  and  at  a 
lower  temperature  with  the  comparable  product  quality 
found in conventional ovens. 

The  "E"  &  6/13  Series  of  ovens  represent  the  very  latest 
in energy efficiency technology with an appreciable 

reduction in NOx emissions over other gas fired ovens, both 
convection  and  conventional.  The  introduction  of  heat 
directly  to  the  cooking  cavity  precludes  any  undue  thermal 
loss  due  to  the  venting  away  of  heated  air  before  it  has 
utilized its energy to cook product. This results in lower flue 
temperatures  and  hence,  less  heat  loss  to  your  kitchen  so 
your  exhaust  and  air  conditioning  systems  do  not  work  as 
hard.  Also,  the  "over-sized"  cooking  cavity  allows  you  to 
cook more products in each load. 

All of this in addition to superior cooking results means the 
"E"  &  6/13  Series  of  gas  fired  convection  ovens  are 
outstanding  values.  In  addition,  lower  NOx  emissions 
means it's environmentally  friendly. Please take the time to 
carefully read the operating instructions. They are important 
in the successful use of your oven. 

 
 
 

WARNING: 

The  "E"  &  6/13  Series  Convection  Ovens  rely  on 
electricity for powering the ignition system and the fan. 
Do not attempt to operate during a power failure.
