5. HOOD VENT:
20.3 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 19.5
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.
