Connect Gas Supply

The gas supply inlet connection is a 3/8" NPT female
connector and is located on the left hand side of the
control valve.

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 platform and gas train on this appliance
may be removed as a unit for servicing or to install or
remove the optional circulating fan (if installed). Provide
some form of pipe union (depending on type of piping)
as close as possible to appliance valve.
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 17.
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 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 17. 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.
