Connect Gas Supply
The gas supply inlet connection is a
3/8” NPT male connector located on
the right hand side of the fi rebox.
The unit is supplied with a stainless
steel fl ex line to allow the appliance
to be disconnected for service. An individual shut-
off valve (not supplied) is required on the supply line
ahead of the fl ex connector.
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.

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 g-
ure below. An internal regulator within the valve controls
the burner manifold pressure.
The correct pressure range is shown in the table in sec-
tion
Speci
fi
cations
of this manual on page 22. The pres-
sure check should be made with the burner alight and at
its highest setting. See
Lighting Instructions
section for
