Ventilation Air - Viking V36SO Series Installation, Operation & Owners Manual

Gas Pressure Regulator
A gas pressure regulator must be installed to regulate the proper flow of gas to the appliance.
The regulator must be installed between the main gas supply line to the unit shut off valve and
the appliance and must be accessible for servicing. Proper sizing of the regulator is extremely
important, check the BTU rating of the appliance or appliances being regulated by the regulator.
Note:
Contact the factory for regulator sizing when multiple appliances are being installed in a line up or
island suite configuration and are interconnected using the front manifold connections.
Note:
Gas pressure should be checked when the unit is installed and all other equipment on the same
line is on. The operating gas pressure must be the same as that specified on the rating plate. If
necessary, pressure adjustment may be made at the pressure regulator.
The appliance and its individual shut-off valve must be disconnected from the gas supply piping
system during any pressure testing of that system where pressures are in excess of ½ PSIG
(3.45KPA).
When test pressures are ½ PSIG (3.45KPA) or less, the range must be isolated from the gas
supply system by closing its individual manual shutoff valve.
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.

Ventilation Air

The following notes are intended to give general guidance. For detailed recommendations, refer
to the applicable codes in the Country, State, County and City of installation.
•
Do not obstruct the flow of combustion and ventilation air.
Proper ventilation is critical for optimum performance. The ideal method of ventilating gas fired
equipment is the use of properly designed canopy that should extend six inches (152mm) beyond
all sides of the appliance (s) and six feet six inches (1981mm) above the floor. 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, on their web site: http://www.nfpa.org/.
A strong exhaust will create a vacuum in the room. For an exhaust vent to work properly,
replacement air must be equal to the amount of air exhausted. An imbalance between exhaust
and replacement air can cause degradation in the appliance's performance.
All gas burners and pilots need sufficient air to operate. Large objects should not be placed in
front of the appliance(s) that would obstruct the flow of air into the front.
