The unit is supplied with a stainless steel
fl
ex line to
allow the appliance to be disconnected for service.
The
fl
ex line is supplied loose to avoid damage during
shipping. Connect the
fl
ex to the appliance valve as
shown below. An individual shut-off valve (not supplied)
is required on the supply line ahead of the
fl
ex
connector.
Pressure test the supply line for leaks.
The appliance and its individual shut-off 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-off
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.
Pressure Test Points
The minimum supply pressure is given in the section
Specifi cations
of this manual—page 19.
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 off.
• Open the manual shut-off valve.
• Test for leaks by applying a liquid detergent or soap
solution to all joints. Bubbles forming indicate a gas
leak.
Never use an open
fl
ame to check for leaks.
Correct any leak detected immediately.
The pressure test tapping locations are shown in
the
fi
gures on the right. An internal regulator within
the valve controls the burner manifold pressure. The
correct pressure range is shown in the table in section
Specifi cations
of this manual on page 19. The pressure
check should be made with the burner alight and at its
highest setting. See
Lighting Instructions
section for full
operating details on page 16.
