Gas Connections; Testing The Gas Supply System; Flue Connections - Vulcan-Hart HDR V series Operation Manual

GAS CONNECTIONS

All gas supply connections and any pipe joint compound used must be resistant
to the action of propane gases.
This appliance must be connected with a gas supply line as large or larger ID (net inside diameter) than
the gas pipe inlet provided on the rear of the appliance. Connect gas supply to the range(s). Make sure
the pipes are clean and free of obstructions, dirt, and piping compound.
Codes require that a gas shutoff valve be installed in the gas line ahead of the range(s).
An external gas pressure regulator must be installed on the unit at the time of installation. The
regulator must be listed by a nationally recognized testing agency. These appliances are rated at the
following pressure: Natural Gas - 6" W.C. (Water Column) (1.25 kPa); Propane Gas - 10" W.C.
(2.49 kPa).
Prior to lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
A. Check all joints prior to the gas valve (solenoid) before lighting unit.
B. Check all joints beyond gas valve (solenoid) after unit is lit.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

TESTING THE GAS SUPPLY SYSTEM

When test pressures exceed
disconnected from the gas supply piping system.
When test pressures are
system by closing its individual manual shutoff valve.

FLUE CONNECTIONS

DO NOT obstruct the flow of flue gases from the flue duct located on the rear of the range. It is
recommended that the flue gases be ventilated to the outside of the building through a ventilation
system installed by qualified personnel.
A minimum of 18" (457 mm) must be maintained between the ventilation system and the cooking
surface.
Information on the construction and installation of ventilating hoods may be obtained from the standard
for " Vapor Removal from Cooking Equipment ," NFPA No. 96 (latest edition), available from the
National Fire Protection Association, Batterymarch Park, Quincy, MA 02169-7471.
