Set-up Gas Supply

The gas supply inlet connec-
tion is a 1/2" NPT male line
stub located on the rear left
hand side of the appliance
(same location for LJ and RJ appliances).

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.
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 ap-
plied 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 individual manual shut-off
valve during any pressure testing of the gas supply pip-
ing 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 24.
All piping and connections must be tested for leaks af-
ter 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 so-
lution 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 gure below. An internal regulator within the valve con-
trols the burner manifold pressure. The correct pressure
range is shown in the table in section Specifi cations of
this manual on page 24. The pressure check should be
made with the burner alight and at its highest setting.
See Lighting Instructions section for full operating details
