F.    ELECTRICAL  CONNECTION:

The  oven,  when  installed,  must  be  electrically  grounded  in  accordance  with  local  codes  and/or  the  latest 
edition  of  the  National  Electrical  Code  ANSI/NFPA  No.  70  in  the  USA  (Canadian  Electrical  Code  CSA 
Standard  C22.1,  Part  1  in  Canada).

In  Europe,  the  appliance  must  be  connected  by  an  earthen  cable  to  all  other  units  in  the  complete 
installation  and,  thence,  to  an  independent  earth  connection  in  compliance  with  EN  60335-1  and/or  local 
codes.

The  electric  motor,  all  the  related  switches,  interior  lights,  and  the  timer/buzzer  are  all  connected  through 
the  6-foot  (1829  mm)  power  supply  cord  located  at  the  rear  of  the  oven.  The  supply  cord  must  be  plugged 
into  a  properly  grounded,  three-prong  receptacle.  DO  NOT  CUT  OR  REMOVE  THE  GROUNDING  PRONG 
FROM  THE  PLUG.

Normal  factory  connections  are  made  for  120  volts  A.C.,  60  hz,  Service  in  USA  and  Canada  or  240  volts 
A.C.,  50  hz  service  in  European  community  countries.  Other  voltages  can  be  supplied  upon  request. 
Electrical  characteristics  of  this  unit  can  be  found  on  the  rating  plate  located  on  the  right  side  of  the  unit.

This  unit  is  provided  with  a  permanently  lubricated  electric  motor.  A  wiring  diagram  may  be  found  on  the 
back  of  the  service  panel  on  the  right-hand  side  and  in  this  manual.

G.    FLUE  CONNECTION    VENTILATION:

Installation  under  ventilation  hood  (standard):

If  the  oven  is  not  vented  directly  and  is  installed  under  a  ventilation  hood,  the  unit  is  ready  to  be  installed  as 
is.  Local  inspectors  and  ventilation  specialists  should  be  consulted  so  that  the  design  and  the  installation  of 
the  hood  conform  to  local/municipal  codes.  In  the  U.K.,  follow  ventilation  requirements  as  detailed  in  B.S. 
5440. 

Optional  direct  venting    (not  available  for  European  community  countries):

If  direct  venting,  a  flue  adapter  and  a  draft  hood  are  required  to  be  installed.  They  prevent  the  flue  gases 
leaving  the  oven  to  be  affected  by  the  air  pressure  changes  on  the  outside  of  the  flue  stack  extending  out  of 
the  building.

 

The  flue  pipe  from  the  draft  hood  must  not  run  downwards  at  any  point  from  the  oven  to  the  final 

outlet.  It  should  always  slant  slightly  upwards.  For  best  results,  is  should  rise  straight  up.  The  venting 
system  shall  be  in  accordance  with  the  National  Fuel  Gas  Code,  ANSI  Z223.1  /  NFPA  54  and  or  the  CSA

 

B149.1,  Natural  Gas  and  CSA

 

B149.2,  Propane  Installation  Codes,  and  local  codes.

NOTE:    DO  NOT  PUT  A  DAMPER  IN  THE  FLUE  AND  DO  NOT  CONNECT  A  BLOWER  DIRECTLY  TO 
THE  FLUE.

If  the  flue  runs  directly  to  the  free  air  outside  the  building,  use  a  wind  deflector  or  a  UL  listed  vent  cap  at  the 
end  of  the  pipe.  Termination  of  the  vent  must  be  at  least  two  feet  above  the  highest  part  of  the  roof  within  ten 
feet.    REF:  AGA  CATALOG  NO.  XH0474.

H.    BURNER  OPERATION: 

The  oven  burner  flame  should  always  have  a  blue  appearance.  This  indicates  a  good  mixture  of  air  and  gas. 
When  using  LP  gas,  the  flame  will  have  a  blue-yellow  appearance.  There  may  be  intermittent  yellow-orange 
flame  noticed.  This  is  caused  by  dust  particles  burning  in  the  flame.

I.    SYSTEM  CHECK-  ROTARY  CONTROL:

(1) 

Open  the  oven  door.

(2) 

Turn  Selector  Switch  to  “HI.”  The  indicator  light  near  Selector  Switch  and  oven  light  will 
illuminate.

(3)

Close  the  door.  Oven  lights  will  go  off  and  fan  will  run.  Make  sure  fan  is  rotating  clockwise  looking 
from  front.

(4)

Press  Oven  Light  switch.  Oven  light  will  go  on  and  will  go  off  when  switch  is  released.
