WARNING

VENTILATION

Failure to properly vent this appliance
may cause SERIOUS INJURY, DEATH, or
PROPERTY DAMAGE. The formation of
volatile substances may cause
suffocation, equipment damage,
operational problems and unsatisfactory
cooking performance as a consequence
of improper venting and is not covered
by your warranty.

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.

Ventilation hoods and exhaust systems shall be
permitted to be used to vent appliances installed in
commercial applications.

In accordance with NFPA 54 for the
Commonwealth of Massachusetts only:

Where automatically operated appliances are
vented through a ventilation hood or exhaust
system equipped with a damper or with a power
means of exhaust, provisions shall be made to
allow the  ow of gas to the main burners only
when the damper is open to a position to properly
vent the appliance and when the power means of
exhaust is in operation.

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.

To prevent SERIOUS INJURY, DEATH, or
PROPERTY DAMAGE:

Installation, air adjustment and/or service
work must be in accordance with all local
codes and must be performed by a trained
service technician qualified to work on
gas appliances.

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).
