Means must be provided for any commercial, heavy-duty cooking appliance to exhaust combustion waste products to the outside
of the building. Usual practice is to place the unit under an exhaust hood. Filters and drip troughs should be part of any industrial
hood. Consult local codes before constructing and installing a hood.
Air movement should be checked during installation. Strong exhaust fans in the hood or in the overall air conditioning system can
produce a slight vacuum in the room and/or cause air drafts – either may interfere with the pilot or main burner performance and
can also be hard to diagnose. If pilot burner or main burner outage problems persist – make up air openings or baffles may have to
be provided in the room.
Electrical Connection -
The standard gas operated convection ovens require a 120 VAC, 60 Hz, 15 AMP electrical service for
operation. The supply cord provided on the appliance is equipped with a three-prong (grounding) plug for protection against
electrical shock hazard. The electrical service in the building must be equipped with a properly grounded three-prong receptacle, in
accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or in Canada – to
Canadian electrical codes, CSA C22.2. Do not cut or remove the grounding prong from this plug.
For gas fired units and any NEC compliant receptacle, properly grounded and with correct
polarity is required.
Electric convection ovens are configured at the factory for operation from 208 VAC, single
phase, or 208 VAC, three-phase electrical service is also an available configuration. Consult
wiring diagram located at the end of this manual and on the back side of the appliance.
Gas Connection -
The single deck oven requires one gas connection; the double deck oven requires two gas connections. The gas
inlet line size of this appliance is 3/4” NPT. For proper operation, the gas supply service line must be the same size or greater than
the inlet line size of the appliance.
Manual Shut Off Valve -
A gas pressure regulator and a contractor-supplied shut-off valve must be plumbed in the gas service line
ahead of the appliance – in a physical location where it can be reached quickly in the event of an emergency.
