Oven Location and Ventilation
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 be-
tween the oven and any combustible or non-com-
bustible construction.
All units
Oven body sides --- 0 cm (0")
D
Oven body back --- 0 cm (0")
D
The following clearances must be available for
servicing.
All units
Oven body sides --- 96.5 cm (38")
D
Oven body back --- 71 cm (28")
D
NOTE: On gas models, routine servicing can
usually be accomplished within the limited
movement provided by the gas hose re-
straint. If the oven needs to be moved
further 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 regular position.
It is essential that a sufficient air supply to the oven
be maintained to provide adequate combustion
and ventilation air.
Place the oven in an area that is free of drafts.
D
Keep the oven area free and clear of all com-
D
bustibles such as paper, cardboard, and flam-
mable liquids and solvents.
VENTILATION
A mechanically driven ventilation system is re-
quired for the removal of excess heat and cooking
vapors. For gas models, a ventilation system is
also required for the removal of the products of
gas combustion. The necessity for a properly de-
signed and installed ventilation system cannot be
over emphasized.
The following are general recommendations and
guidelines for good ventilation. Your specific ap-
plication may require the services of a ventilation
engineer or consultant
The ventilation hood must work well with the build-
ing heating, ventilation and air conditioning
(HVAC) system. The hood exhaust and the supply
air flows should be sized appropriately. Supply air
must be provided by either the hood system or the
building HVAC system in order to prevent an ex-
cessive negative pressure in the oven area. Sup-
ply air should replace approximately 80% of the air
flow exhausted by the hood. The table below can
be used as a guideline, but the correct air flow va-
lues depend on the efficiency of the hood design,
the amount of air flow around the oven, and the
current air flow in and out of the kitchen or oven
area (for existing facilities).

Ideally supply air would be provided through the
building HVAC system or, secondly, through the
hood with an in-line tempering unit. Air supplied di-
rectly from outside the building to the kitchen or
oven area, non-tempered, could be used as sup-
ply air but the design would have to accommodate
potential operational and environmental draw-
backs.
