2 3/4" (front) or 5 1/2" (rear) connection A.F.F.
Route to air-gap drain. Do not slope drain
upwards.
Plug the drain connection that is not in
use. Kit provided to extend drain to either side of
oven.
Rear Drain: 3/4" NPTF
Front Drain: 3/8" NPTF
3. POWER:
Two supplies required. Control circut:
100/50/60/1 or 208-240/50/1
1 kVA transformer supplied for control circuit
operation voltage of 110V. This is a multifunction
transformer, so output voltage should be verified
before operation. Some wiring may be required
to obtain proper output voltage.
Oven fan (1.1kW) operates @ 200/50/60/3 amps
or 380-415/50/3, 2.8-2.5 amps

5. HOOD VENT:
25.4 cm DIA. Connection collar. Customer is to
supply duct and ventilator fan per federal and/or
local codes. Chamber vent (steam) and
combustion exhaust are discharged into the
hood. An air proving switch is factory installed
and integrated with burner system operation. If
proper ventilation is not provided, burner will not
operate. Oven provides a relay to activate a
customer
supplied and powered contactor/relay,
so that when oven is powered up external fan will
operate. The hood requires a minimum of 25.5
m3/min for safe operation. For fan calculation
purposes you should assume 0.15 kPa
resistance through the hood. Grease filters
(optional) may be installed in the hood instead of
standard baffle.
