Power Failure
In the event of a power failure, no attempt should be made
to operate this oven. This unit is gas operated but has
electrical features, motor, electric thermostat and solenoid.
Ventilation and Air Supply
Proper ventilation is highly important for good operation.
There are only two choices for properly venting an oven:
1) canopy hood style or 2) direct venting.
The ideal method
of venting a GAS Convection Oven is through the use of a
properly designed canopy, which should extend 6” (152 mm),
beyond all sides of the appliance and 6’6” (1981 mm) from
the floor.
A strong exhaust fan will crate a vacuum in the room. For an
exhaust system vent to work properly, exhaust and make-up
air must be balanced properly. For proper air balance contact
your local H.V.A.C. contractor.
All gas burners and pilots need sufficient air to operate and
large objects should not be placed in rear and bottom of this
oven, which would obstruct the airflow through the front.
INSTALLATION Continued
Installation of Direct Flue
When the installation of a canopy type exhaust hood is
impossible the oven may be direct vented. Before direct
venting check your local codes on ventilation, in the absence
of local codes, refer to the National Fuel Code NFPA 54, ANSI
Z223.1 (latest revision).
If the unit is to be connected to a direct flue, it is necessary
that the flue cap assembly and down draft diverter be
installed to ensure proper ventilation.
The cap and diverter of the single deck adapts to a 6” stove
pile. The double deck direct vent adapts to an 8” stove pipe.
Direct venting should be positioned on the main top and
fastened with sheet metal screws provided.
DO NOT UNDERSIZE VENT PIPE! This can cause resistance
to flow and impede good venting.
We suggest that if a horizontal run must be used it should
rise not less than 1/4” (6.25mm) for each linear foot of run,
and after a total of 180° of bends you should increase the
size of stove pipe by two (2”, 51mm) inches. The flue should
rise 2’ (60cm) to 3’ (91cm) above the roofline or 2’ (60mm) to
3’(91cm) above any portion of a building within a horizontal
distance of 10 feet (3 meters) .

Fuel Gas code Book NFPA 54, ANSI Z223.1,7,5,3:
