NOTE: A straight gas connection is the ideal condition for the rated BTU/hr. fl ow capacity of the connector.
If a straight connection is not possible and a fl exible gas connector is used, do not twist, kink or excessively
fl ex the connector beyond a U-shape. Flexing the gas connector as described will restrict gas fl ow or may
damage the connector.
Changing a fl exible gas connector may raise the BTU/hr. fl ow capacity enough to allow the machine to
operate within its design specifi cations. (i.e. Removing the quick disconnect fi tting, installing a shorter gas
connector or installing a larger diameter gas connector.)
An alternative may be to move the equipment to a different gas supply location in the kitchen. (i.e. Closer
to the main supply into the kitchen or away from other equipment with high BTU/hr. input requirements.)
The combi oven is equipped with a factory preset pressure regulator. Natural gas pressure regulators are
preset for 5.0" W.C. (1.2 kPa). Propane gas pressure regulators are preset for 10.0" W.C. (2.46 kPa). No
further adjustment should be required. Check gas pressures with a manometer at time of installation to
verify that they agree with the pressures specifi ed.
Conversion Kit - GASKIT-ABC – Propane & altitude kit (2,000-10,000 ft.) are available and are to be fi eld
installed as needed.
Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water
solution. Do not use an open fl ame. After piping has been checked for leaks, all piping receiving
gas should be fully purged to remove air.

TESTING THE GAS SUPPLY SYSTEM
When gas supply pressure exceeds
1
/2 psig (3.45 kPa), the oven and its individual shutoff valve must be
disconnected from the gas supply piping system.
When gas supply pressure is
1
/2 psig (3.45 kPa) or less, the oven should be isolated from the gas supply
system by closing its individual manual shutoff valve.
FLUE GAS EXHAUST
The fl ue is shipped loose and must be installed prior to operation. Failure to install
will cause service issues and will void warranty.
DO NOT obstruct the fl ow of fl ue gases from the fl ue located on the top of the combi oven. It is recommended
that the fl ue gases be vented to the outside of the building through a ventilation system installed by
qualifi ed personnel. Information on the construction and installation of ventilating hoods may be obtained
from Vapor Removal from Cooking Equipment, NFPA-96 (latest edition) available from the National Fire
Protection Association, Batterymarch Park, Quincy, MA 02269.
The output temperature of the exhaust fumes reach 480°F.
