2.5 VENTILATION

Proper ventilation is highly important for good
oven operation The use of a mechanical exhaust
system is ideal A properly designed unit will extend
approximately 4" to 6" (102-152mm) beyond all
sides of the oven unit In such instances the oven will
be equipped with a flue deflector, which is shipped
separate from the oven in the stand carton If the flue
outlet is to be connected directly to a chimney, then
a down draft diverter should be employed AT NO
TIME SHOULD A DAMPER BE INSTALLED IN THE
EXHAUST SYSTEM OF THIS OVEN
2.5.1 Flue Deflector Installation
To install deflector, remove back row of screws from
oven top panel Add flue deflector with open side
facing front, and replace screws For stacked ovens,
see Figure 2-3, view "A"
2.6 INSTALLATION CHECK-OUT
After the oven is completely assembled and
properly located with gas and electrical supplies
connected, the unit should be given a thorough
check-out before being put into operation Check-out
procedures for the oven are given in subsection 2 6
2 If the unit fails to perform as described, consult the
trouble shooting guides in section 5 for corrective
action
Before making this check-out, the operator must
be thoroughly familiar with the operating procedures
in Section 3, and with the function of
each control described in Table 3 1 Reference Figure
3-1 for identification of controls
2.6.1 Initial Control Settings
Power switch and thermostat dial are in OFF
position
2.6.2 Oven Check-Out
A final check of the controls and connections
should be made as follows
1. Make sure that the blower guard is properly
mounted See Figure 6-1
2. With a level on the oven shelves make sure that
the oven is level both front and back left and right
To adjust, turn feet in stand legs NOTE Be sure
wire shelf supports are in, not on, brackets
3. Make sure that gas and electrical supplies are
available to the unit
4. Set thermostat dial at 350°F
5. Place power switch in the ON position with doors
open
6. Close doors Indicator light should come on, fan
should come on and rotate clockwise (seen from
front) NOTE Buzzer may sound for an instant
a) If fan does not start, or starts and immediately
stops, press MOTOR RESET
b) If buzzer sounds, press IGNITION RESET
7. If fan still does not work or buzzer sounds again,
see Tables 5-1 and 5-2 for troubleshooting and
electrical fault isolation
8. Indicator light will remain on while oven is heating,
and go out when preset temperature is reached
During the heat-up period, some slight smoke or
fumes may result due to oil or grease on metal
surfaces This should cease after five minutes
9. During initial burner operation, observe flame
angle of each burner through the louvers on the
lower front panel If flames are not vertical, burners
may not be positioned properly, see subsection
6.4.4
10. After this check is completed, turn thermostat dial
and power switch to OFF position
