SITE INSTALLATION
The Alto-Shaam cook
and hold oven must be
installed in a location
that will permit the
oven to function
for its intended
purpose and to allow
adequate clearance
for ventilation,
proper cleaning, and
maintenance access.
1. The oven must be installed on a stable and
level surface.
2. DO NOT install this appliance in any area
where it may be affected by any adverse
conditions such as steam, grease, dripping
water, high temperatures, or any other severely
adverse conditions.
3. DO NOT store or use any flammable liquids or
allow flammable vapors in the vicinity of this
oven or any other appliance.
4. This appliance must be kept free and clear of
any combustible materials.
5. This appliance must be kept free and clear
of any obstructions blocking access for
maintenance or service.
®
Emissions testing conducted by Underwriters
Laboratories, Inc.®was found to be in compliance
with the applicable requirements of NFPA96:
2004 Edition, Par. 4.1.1.2. U.L emissions
sampling of grease laden vapor resulted in a total
of 0.55 milligrams per cubic meter with no visible
smoke and is considered representative of all
oven models in the line. Based on these results,
hood installation and/or outside venting should
not be a requirement in most areas. Verify local
codes for locations where more restrictive codes
are applicable.

INSTALLATION
MINIMUM CLEARANCE
REQUIREMENTS
18” (457mm) minimum clearance at the back from
heat producing equipment. To protect the electronic
control, maintain sufficient side clearance to prevent
the control area from reaching any temperature at or
above 140°F (60°C). The oven must not be installed
in any area where it may be affected by steam,
grease, dripping water, extreme temperatures, or
any other severely adverse conditions.

INSTALLATION AND START-UP
A number of adjustments are associated with
initial installation and start-up. It is important
that these adjustments be conducted by a qualified
service technician. Installation and start-up
adjustments are the responsibility of the dealer
or user. These adjustments include but are not
limited to thermostat calibration, door adjustment,
leveling, electrical hook-up and installation of
optional casters or legs.
LEVELING
Level the oven
from side-
to-side and
front-to-back with the use of a
spirit level. For ovens installed with casters, it is
important that the installation surface be level due
to the probability of frequent oven repositioning.
We recommend checking the level of the oven
periodically to make certain the floor has not
shifted nor the oven moved.
NOTE: Failure to properly level this oven can
cause improper function and will result
in the uneven baking with products
consisting of semi-liquid batter.
