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 o 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.
