Connect Gas Supply
The gas supply inlet connection is a 1/2” NPT female.
Gas shut-o
ff
valve supplied on the end of stainless steel
fl
exible connector. Flex connector is located on the left
hand rear corner of the appliance.
Use only new black iron or steel pipes, CSST, 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 su
ffi
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-o
ff
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-o
ff
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 result in regulator or valve
damage and void the warranty. Consult your dealer in
case of damage.
Pressure Test Points
The minimum supply pressure is given in the section
Speci
fi
cations of this manual—page 6.
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 o
ff
.
• Open the manual shut-o
ff
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
gure below. An internal regulator within the valve
controls the burner manifold pressure.
The correct pressure range is shown in the table in
section Speci
fi
cations of this manual on page 6. 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 36.
