Pressure Testing
Pressure Test Points
The minimum supply pressure is given in the section
“Speci
fi
cations” on page 6.
All piping and connections must be tested for leaks
after installation or servicing. All leaks must be
corrected immediately.
When testing for leaks:
• Make sure that the appliance is turned o
ff
.
• Open the manual shut-o
ff
valve.
• Test for leaks by applying a liquid detergent or soap
solution to all joints. Bubbles forming indicate a gas
leak.
The pressure test tapping locations are shown in
the
fi
gure at right. An internal regulator within the
valve controls the burner manifold pressure. The
correct pressure range is shown in the table in section
“Speci
fi
cations” on page 6. The pressure check
should be made with the burner alight and at its
highest setting. See “Appendix A—Lighting Instructions”
on page 58 for full operating details.
Installation
Gas Supply
Caution
Never use an open flame to check for leaks!
Correct any leak detected immediately.
Pressure test the supply line for leaks.
The appliance and its individual shut-o
ff
valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply
piping system by closing its individual manual shut-o
ff
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2
psig (3.5 kPa).
Failure to either disconnect or isolate the appliance
during pressure testing may result in regulator or valve
damages and void the warranty. Consult your dealer in
case of damages.
