Testing The Gas Supply System; Flue Connections - Vulcan-Hart GH30 Installation & Operation Manual

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.
Single Range Installations
All single stand-alone ranges require installation using an A.G.A. design-certified pressure regulator
with an outlet (manifold) pressure of 6" (1.49 kPa) Water Column for natural gas supply, and outlet
(manifold) pressure of 10" (2.49 kPa) Water Column for propane gas supply (available from Vulcan-
Hart). The regulator must be adjusted to agree with the pressures indicated on the rating plate. When
installing the regulator, follow instructions supplied by the regulator manufacturer.
Manifold pressure for the incoming store line must be at least 7" (1.74 kPa) Water Column for natural
gas and 11" (2.74 kPa) Water Column for propane gas.
If a pressure regulator is not installed, the warranty on related parts, as well as performance related
problems, will not be covered.
Battery Installations
The gas manifold of this range, or the battery of which it is a part, must be connected to an A.G.A.
design-certified gas appliance pressure regulator (available from Vulcan-Hart). The pressure regulator
must have a maximum regulation capacity to handle the total connected load and must have an
adjustment range for manifold pressure marked on the range rating plate. If the manifold pressure of
the connected ranges is not the same, a separate regulator must be supplied for all ranges operating
under different manifold pressure ratings.
If a pressure regulator is not installed, the warranty on related parts, as well as performance related
problems, will not be covered.

TESTING THE GAS SUPPLY SYSTEM

1
When test pressures exceed / psig (3.45 kPa), the range and its individual shutoff valve must be
2
disconnected from the gas supply piping system.
1
When test pressures are / psig (3.45 kPa) or less, the range must be isolated from the gas supply
2
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" (45 cm) must be maintained between the grease removal device and the cooking
surface.
