PRESSURETESTING
The appliancemust be isolated from the gas supply piping system by
closingits individualmanualshut-offvalve during anypressuretesting of
the gas supply piping systemat test pressuresequalto or less than 1/2
PSIG (3.5kPa).
This appliance, as well as its individual shut-off valve, must be
disconnectedfrom the gas supply piping system during any pressure
testing of the systemat test pressuresin excessof 1/2 PSIG (3.5kPa).
When checkingappliance regulatorfunction, make certain pressure of
natural gas supply is between6 and 14 inches of water column or, if
convertedfor LP gas, between11and 14 inches.
WARNING
Gas leaks may occur in your system and result in a dangerous
situation.Gasleaksmaynotbe detectedbysmellalone.Gassuppliers
