Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
The oven is provided with a regulator integral to the gas solenoid valve and requires no external
regulator. Location of the gas inlet is at the rear of the oven. Codes require that a gas shutoff valve
must be installed in the gas line ahead of the oven.
Connect the oven(s) to the gas supply after leveling. The gas supply line must be at least the equivalent
3
⁄4"
(1.9 cm) iron pipe. Make sure the pipes are clean and free of obstructions, dirt, or pipe joint
of
compound. The ovens are equipped with fixed burner orifices which match the installation elevation.
– 7 –
Natural gas pressure regulators are preset for 3.5" W.C. (Water Column) (0.9 kPa); propane gas
pressure regulators are preset for 10" W.C.
(2.5 kPa).
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
1
When gas supply pressure exceeds
⁄2 psig (3.45 kPa), the oven and its individual shutoff valve must be
disconnected from the gas supply piping system during any pressure testing of the system.
1
When gas supply pressure is
⁄2 psig (3.45 kPa) or less, the oven should be isolated from the gas supply
system by closing its individual manual shutoff valve during any pressure testing of the system.
ADJUSTMENTS
Air Adjustment
Although main burner air is adjusted before shipment, it should be checked at the time of installation.
Excessive air will cause flames to lift off a burner when cold or may cause flash-back during normal
cycling of the oven, particularly when propane gas is used.
Insufficient air will cause flames to burn with a yellow tip and result in carbon accumulation in the flame
chamber and heat exchanger tubes.
Contact your local Vulcan-Hart authorized servicer if required.
VENT SYSTEM
DO NOT obstruct the flow of flue gases from the flue located on the rear of the oven. It is recommended
that the flue gases be ventilated to the outside of the building through a ventilation system installed by
qualified personnel.
Ovens may use an optional down draft diverter flue method. This optional down draft diverter must be
purchased from the oven manufacturer and vented to the outside; otherwise, the installation of any
such device will void all oven certifications and warranties. When the diverter is supplied, it may be
connected to a Type “B” vent.
From the termination of the flue to the filters of the hood venting system, a minimum clearance of
(45.7 cm) must be maintained.
