The line must be disconnected from the gas sup-
ply line by closing the main supply manual gas shut-
off valve (gas cock) during any pressure testing of the
gas supply piping system that is equal to or exceeds
pressuresof1/2psig(3.5kPa).
6.4TestingGasPressure
Proper gas pressure provides a consistent flow of
gas to the appliance and is instrumental in checking
for gas leaks. There are two pressure test points on
the front of the fireplace control valve where test
gaugeconnectionsaremade.SeeFig.6.4.Gauge
connections are identified by:
