The oven must be mounted on the factory equipped
oven legs or on an optional oven stand. Installation
on a solid or concrete base that in any way restricts
air flow may void the warranty.
All clearances for a proper ventilation air supply
must be maintained to minimize fire hazard. Do
not locate the oven immediately adjacent to any
other heat-generating appliance.
A number of adjustments are associated with
initial installation and start-up. Adjustments
must 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,
and gas pressure verification. The Platinum series
oven burners are factory-adjusted with fixed air
openings and require no field adjustment.
LEVELING
The oven should be
leveled before the gas
supply is connected. Level the oven from
side-to-side and front-to-back with the use of a
spirit level. For ovens installed on a mobile stand,
it is important that the floor 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 or the oven moved.
NOTE: Failure to properly level this oven can
cause improper function as a result
of erratic burner combustion and will
result in the uneven baking of products
consisting of semi-liquid batter.
INSTALLATION REQUIREMENTS
WARNING
Inadequate ventilation, or failure to
ensure an adequate supply of fresh
air will result in a high ambient
temperature at the rear of the
appliance. An excessive ambient
temperature can cause the thermal-
overload protection device on the
blower motor to trip resulting in
severe damage to the blower motor.
CAUTION
TO PREVENT PERSONAL INJURY,
USE CAUTION WHEN MOVING OR
LEVELING THIS APPLIANCE.

GAS SUPPLY & INSTALLATION
GAS REQUIREMENTS
The gas inlet is located at the back of the oven.
Code requires the installation of a manual gas
shutoff valve to be installed in the gas line ahead
of the oven. This oven is also equipped with
fixed burner orifices determined by the elevation
specified as the initial installation location.
The oven is furnished with a regulator integral
to the operation of the gas solenoid valve
and may not require an additional external
regulator. To ensure safe and proper operation,
the gas pressure regulator installed in the oven
is required for use with both natural gas and
propane. If the connected pressure exceeds
14.0" W.C. (3.48 kPa), a step-down regulator
is required. A step-down regulator is not the
responsibility of the manufacturer.
Use an approved pipe sealant at all connections.
Do not use Teflon®tape. Gas supply connections
and pipe joint compound must be resistant to the
action of propane gases. Pipes must be clean, free
of obstructions and pipe joint compound.
GAS CONNECTION
In the U.S.A., installation must conform to local
codes or, in the absence of local codes, with the
current edition of the National Fuel Gas Code,
NFPA-54 and ANSI Z223.1-1980 (latest edition).
In Canada, installation must be in accordance
with local codes, CAN/CGA-B149.1,
Installation
for Natural Gas Burning Appliances and
Equipment (latest edition) or CAN/CGA-B149.2
Installation for Propane Burning Appliances
and Equipment (latest edition).
The inlet supply line must be properly sized
to accommodate all individual appliances
simultaneously used on the same line but
must never be smaller than 3/4" NPT.

GAS SUPPLY & INSTALLATION
GAS CONNECTION
�FOR OVENS ON CASTERS
The oven must be supplied with a flexible
connector that complies with The Standard for
Connectors for Movable Gas Appliances, ANSI
Z21.69, CGA 6.16 and addenda Z21.69a (latest
editions). A quick disconnect device must be
installed to comply with The Standard for Quick
Disconnect Devices for Use with Gas Fuel, ANSI
Z21.41 and CAN1-6.9 (latest editions). A flexible
connector is not supplied by the factory.
Adequate means must be
provided to limit the
movement of the appliance.
Limitation of movement
must be made without
depending on the connector,
the quick disconnect device,
or the associated piping
designed to limit oven
movement. Mounting holes
for a restraining device are
located on the lower back
flange of the oven chassis.
Shut the gas supply
OFF
if it becomes
necessary to disconnect the restraint.
Reconnect the restraint immediately
following the return of the oven to its
original position. Turn the gas supply
ON
after the restraint has been reconnected.
LEAK TESTING
Use a soap and water solution on all gas supply
line connections.
