INSTALLATION
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.
NOTICE: 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
NOTICE
Inadequate ventilation, or failure to ensure an
adequate air flow may result in high ambient
temperatures at the rear of the appliance. High
ambient temperatures can cause the thermal-
overload protection device on the blower motor to
trip resulting in severe damage to the blower motor.

VENTILATION
Ventilation Hoods
Proper venting along with a sufficient quantity of
make-up air is essential for proper oven operation.
A mechanically driven, canopy exhaust hood is
the preferred method of ventilation and must
conform to local codes along with the current
version of NFPA-96 Vapor Removal from Cooking
Equipment (latest edition). The oven hood must
extend 6" (152mm) beyond all sides of the oven.
The distance from the floor to the bottom edge of
the hood should be between 6' (1829mm) and
7' (2134mm).
A ventilation hood that supplies make-up air
down the back vertical wall should be avoided
since air currents can interfere with the oven
flue exits. If such installation is unavoidable, an
additional draft hood, specifically designed to
deflect downdrafts, must be installed.
Direct Venting
When necessary, direct venting can be used
in situations where space is limited or to help
offset the high cost of ventilation hoods.
Direct venting should be installed in
compliance with local codes by a certified
professional. In the absence of local codes,
refer to National Fuel Code NFPA 54, ANSI
Z223.1 (latest revision).
WARNING
Failure to properly vent this appliance
