  In order to avoid any backpressure

in the oven, do not make a solid connection to
any drain. Failure to do so can damage the
oven and will void the warranty.

The 1¼" NPT threaded fitting on the drain
outlet must be extended a minimum of 12"
(305 mm) – maximum of 72" (1829 mm)
away from the Comb Oven base, to an open
air gap type drain. Do not reduce the 1¼"
NPT drain piping throughout its length.

 Provide a suitable floor sink with a minimum
depth of 12" (305 mm). The floor sink is NOT
to be directly under the oven and should be at
a distance so that steam vapors will not enter
the Combi Oven from underneath. The drain
should slope down away from the oven ¼" for
every foot of drain pipe length. The drain pipe
should be either iron or copper. DO NOT use
PVC pipe; PVC pipe may lose its rigidity or
glue may fail.

In order to avoid any back pressure in the
oven, do not connect solidly to any drain
connection.

Local codes may require the oven to be located
under an exhaust hood. Information on the
construction and installation of ventilating
hoods may be obtained from Vapor Removal
from Cooking Equipment, NFPA Standard No.
96 (latest edition).

Before using the oven for the first time, it must
be “burned in” to release any odors that might
result from heating the new surfaces in the
oven. Remove the racks and rack guides and
thoroughly clean in sink with soap and water.
Thoroughly clean with soap and water the
interior of the oven. Refer to cleaning
instructions in this manual. Operate the oven
at maximum thermostat setting for 45 minutes
in Convection Mode.

Make sure the hinged back of the oven cavity
is completely closed and the thumb screws
are secured properly.

Install the rack guides and racks.
