INSTALLATION
Ventilating Hood
The ideal method of ventilating a convection oven is the use of a properly designed ventilating hood. The hood should extend at least 6” beyond all sides of the oven. The hood should
be connected to an adequate mechanical exhaust system.
Information on the construction and installation of ventilating hoods may be obtained from the
“Standard for the Installation of Equipment for the Removal of Smoke and Grease Laden
Vapors from Commercial Cooking Equipment”, NFPA No. 96– latest addenda, available from
the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
It is also necessary that sufficient room air ingress be allowed to compensate for the amount
of air removed by the ventilating system. Otherwise, a subnormal atmospheric pressure will
occur which may interfere with burner performance or may extinguish the pilot flame. In case
of unsatisfactory oven performance, check with the exhaust fan in the “OFF” position.
Direct Flue Connection
If the oven is connected directly to an outside flue, a draft hood (P/N 24678-6) must be used.
The flue should rise at least 10 feet above the roof or any surrounding structure. The flue
must be terminated with an U.L. listed vent cap or spinner.
Clearances
Adequate clearance must be provided in the aisle and at the side and back to allow the doors
to open sufficiently to permit the removal of the racks and for serviceability. Adequate clearance for air openings into the combustion chamber must be provided.
A minimum clearance of one inch must be maintained behind the motor. Care must be taken
to provide adequate air circulation to prevent the motor from overheating.

INSTALLATION
CAUTION
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION
AIR TO THE OVEN. KEEP THE APPLIANCE AREA FREE AND CLEAR
FROM COMBUSTIBLES
Solid state components have a very short life span when exposed to temperatures
above 175°F (80° C), therefore, certain installation precautions are necessary. The
Vectaire HX oven have been designed to operate below this temperature when properly
installed. The following precautions must be observed:
1. Do not obstruct the flow of air through the vent openings at the top of the oven, or
the flow of room air to the oven bottom or lower front portion of the burner access
panel.
2. Do not mount the oven on a curb unless it has been equipped with the Toe Base
(P/N:6024-0) for this type of installation.
3. When stacking ovens, never reverse the top and bottom oven sections.
4. Never stack a solid state controlled Vectaire convection oven, SE or HX series, with
a standard Vectaire or another brand of oven without first consulting the factory.
Certain ovens are not compatible, or a stacking kit may be required.
SPECIAL CAUTION
DO NOT PLACE HIGH HEAT PRODUCING EQUIPMENT ADJACENT TO THE RIGHT
SIDE OF A VECTAIRE HX CONVECTION OVEN. SURFACE TEMPERATURES
EXCEEDING 175°F (80°C) CAN CAUSE PREMATURE COMPONENT FAILURE NOT
COVERED UNDER MANUFACTURER’S WARRANTY. THE OVENS NEED 6”
MINIMUM CLEARANCE ON THE RIGHT SIDE BETWEEN SIMILAR OVEN OR
OTHER COOKING EQUIPMENT. OPTIONAL INSTALLATION KITS ARE AVAILABLE
TO REDUCE THE MINIMUM CLEARANCE BETWEEN SIMILAR OVENS TO 1” AND
BETWEEN OTHER EQUIPMENT TO 2”. CONSULT FACTORY.

INSTALLATION
Gas Connection
Before connecting oven to the gas supply line, be sure that all new piping has been cleaned
and purged to prevent any foreign matter from being carried into the controls by the gas. In
some cases, filters or drops are recommended. A separate gas shutoff valve must be installed
upstream from the gas pressure regulator adjacent to the oven and be located in an accessible area.
It is important that adequately sized piping be run directly to the point of connection at the
oven, with as few elbows and tees as possible. Consult local gas company for proper piping
size and gas pressure.
THIS OVEN IS EQUIPPED WITH A COMBINATION GAS VALVE THAT INCLUDED A
GAS PRESSURE REGULATOR. NO ADDITIONAL REGULATOR NEEDS TO BE
INSTALLED TO THIS UNIT.
For Natural Gas: This pressure regulator is factory adjusted for 3.5” W.C. manifold
pressure. The maximum inlet pressure to the regulator should not exceed 10.5” water column.
For Propane Gas: This gas pressure regulator is factory adjusted for 10” W.C. manifold
pressure. The maximum inlet pressure to the regulator should not exceed 21” water column.
Connect the gas supply line from the service gas shutoff valve to the inlet side on the unit
using 3/4” pipe and a 3/4” to 1/2” reducer. If flexible or semi-flexible connectors are used, an
AGA listed flexible connector with an I.D. equal to 3/4” pipe must be used. DO NOT USE A
DOMESTIC APPLIANCE TYPE GAS FLEXIBLE CONNECTOR. Avoid kinks or sharp bends
that could restrict gas flow.
PIPE JOINT COMPOUND OR THREAD SEALANT THAT IS USED SHOULD BE
RESISTANT TO ACTION OF LIQUEFIED PETROLEUM GASES.
Turn gas shutoff valve “ON” and immediately check carefully for gas leaks. Do this before
TEST ALL PIPE JOINTS FOR LEAKS BEFORE OPERATING OVEN. THIS INCLUDES ALL
GAS CONNECTIONS THAT MAY HAVE LOOSENED DURING SHIPMENT. USE A RICH
SOAP SOLUTION (OR OTHER ACCEPTED LEAK TESTER) AROUND ALL PIPE CONNEC-
TIONS AND ALL OTHER JOINTS. DO NOT USE AN OPEN FLAME. ABSOLUTELY NO
LEAKAGE SHOULD OCCUR, OTHERWISE THERE IS A DANGER OF FIRE OR
EXPLOSION DEPENDING UPON CONDITIONS. NEVER USE IF LEAKAGE IS DETECTED.
