D.    LOCATION  AND  MINIMUM  CLEARANCES:

Move  the  oven  to  its  final  location  keeping  the  minimum  clearance  from  the  back  of  the  oven  to  the  wall.  This 
clearance  is  necessary  for  safe  operation  and  to  provide  proper  air  flow  to  the  burner  chamber.

MINIMUM  CLEARANCES  FROM  COMBUSTIBLE  AND  NONCOMBUSTIBLE  CONSTRUCTION

E.    GAS  CONNECTION:

The  ovens  should  not  be  installed  on  the  same  gas  supply  line  with  space  heaters,  boilers  or  other  gas 
equipment  with  high  intermittent  demand.

The  installation  of  the  oven  must  conform  to  the  latest  local  codes  or 

National  Fuel  Gas  Code,  ANSI  Z223.1, 

Natural  Gas  Installation  Code,  CAN/CGA-B149.1,  or  the  Propane  Installation  Code,  CAN/CGA-B149.2.

The  appliance  must  be  isolated  from  the  gas  supply  piping  system  by  closing  its  manual  shut-off  valve 
during  any  pressure  testing  of  the  gas  supply  piping  system  at  test  pressures  equal  to  or  less  than  ½  psig 
(3.45kpa).  The  appliance  and  its  shut-off  valve  must  be  disconnected  from  the  gas  supply  piping  system 
during  any  pressure  testing  of  that  system  at  test  pressures  in  excess  of  ½  psig  (3.45kpa).

Use  a  pipe  joint  compound  that  is  resistant  to  the  action  of  liquefied  petroleum  gases  when  making  gas 
connections.  For  Propane  gas,  use  at  least  ½”  (13  mm)  pipe  or  tubing  with  a  5/8”  (16  mm)  inside  diameter. 
For  Natural  gas,  use  ¾”  (19  mm)  pipe.
The  gas  pressure  regulator  is  part  of  the  combination  valve  and  is  adjusted  to  yield  a  pressure  of  3.5”  water 
column  (9  mbar)  for  Natural  Gas.  If  the  oven  is  ordered  for  use  on  Propane  Gas  or  Butane,  the  pressure 
regulator  in  the  combination  valve  is  preset  at  the  factory  to  yield  a  pressure  of  10”  water  column  (25  mbar).

 

NOTE:

  No  external  regulator  is  required.

Gas  supply  pressure  in  the  European  Community  countries  should  be  as  below.

Gas  Type Supply  Pressure

Gas  Type Supply  Pressure

G20

20  mbar

G30

30  or  50  mbar  depending  on  country

G25

25  mbar

G31

30,  37,    or  50  mbar  depending  on  country

G20/25

20/25  mbar

A  separate  shut-off  valve  for  each  oven  must  be  provided.  It  should  be  as  close  as  possible  to  the  place 
where  the  gas  line  goes  into  the  oven.  It  must  be  located  such  that  it  is  easily  accessible.  When  stacking  with 
another  oven,  two  shut-off  valves,  one  for  each  of  the  two  ovens,  must  be  provided.

After  the  Gas  Supply  has  been  connected,  it  is  extremely  important  to  check  all  the  piping  for  leaks. 
Use  a  soap  and  water  solution  or  a  product  expressly  made  for  this  purpose.  Do  not  use  matches, 
candles  or  a  flame  and  so  forth  to  check  leaks  since  these  methods  are  extremely  dangerous.

CAUTION:

  Do  not  set  the  oven  with  its  back  flat  against  the  wall.  It  will  not  operate 

properly  unless  there  is  at  least  three  inches  breathing  space  behind  the  oven

!

!

 

Suitable  for  installation  on  combustible  floor  when  installed  with  legs  or  casters 
provided.

!

!

CAUTION: 

Do  not  store  combustible  items  or  materials  on  racks.
