OVEN LOCATION
The well planned and proper placement of your
oven will result in long term operator convenience
and satisfactory performance.
The following clearances must be maintained beĆ
tween the oven and any combustible or nonĆcomĆ
bustible construction.
DOven body right side - 6" (15cm)
DOven body left side - 6" (15cm)
DOven body back - 6" (15cm)
DOven body bottom - 6" (15cm)
Area must be accessible for proper servicing.
NOTE: On gas models, routine servicing can usu
ally be accomplished within the limited
movement provided by the gas hose re
straint. If the oven needs to be moved fur
ther from the wall, the gas must first be
turned off and disconnected from the oven
before removing the restraint. Reconnect
the restraint after the oven has been re
turned to its normal position.
It is essential that an adequate air supply to the
oven be maintained to provide a sufficient flow of
combustion and ventilation air.
DPlace the oven in an area that is free of drafts.
DKeep the oven area free and clear of all combusĆ
tibles such as paper, cardboard, and flammable
liquids and solvents.
DDo not place the oven on a curb base or seal to
a wall. Either condition will restrict the proper
flow of combustion and ventilation air resulting
in damage to the oven.
