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 thermaloverload protection device on the
blower motor to trip resulting in severe
damage to the blower motor.
C A U T I O N
TO PREVENT PERSONAL INJURY,
USE CAUTION WHEN MOVING OR
LEVELING THIS APPLIANCE.
I N S T A L L A T I O N R E Q U I R E M E N T S
The oven must be mounted on the factory equipped
oven legs or on an optional oven stand. Installation
n a solid or concrete base that in any way restricts
o
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-toside 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 nor the oven moved.
NOT E: 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, air adjustment and/or
service work must be in accordance
with all local codes and must be
p
erformed by a certified service
technician qualified to work on
gas appliances.
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., installa tion must conform to local
codes or, in the absence of local codes, with the
current edi tion of the N ation al Fue l Gas C od e,

editions). A quick disconnect device must be
installed to comply with The Standard for Quick

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, nor the
associated piping designed
to limit oven movement.
Mounting holes for a
