Use only new black iron or steel pipes or copper tubing
if acceptable—check local codes. Note that in USA,
copper tubing must be internally tinned for protection
against sulfur compounds.
The burner module and gas train on this appliance
may be removed as a unit for servicing. The fl ex pipe
supplied with the unit provides a union for removal of
the module.
Unions in gas lines should be of ground joint type.
The gas supply line must be sized and installed to
provide a supply of gas suffi cient to meet the maximum
demand of the appliance without undue loss of
pressure.
Sealant used must be resistant to the action of all
gas constituents including LP gas. Sealant should be
applied lightly to male threads to ensure excess sealant
does not enter gas lines.
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 equipment shut-off valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2
psi (3.5 kPa).
Failure to either disconnect or isolate the appliance
during pressure testing may resulting regulator or
valve damages and void the warranty. Consult your
dealer in case of damages.

Installation
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 is
shown in the fi gure
below. 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 13.
