Installation
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, 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 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 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" on page 6 of this manual.
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.
WARNING
NEVER USE an open flame 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 "Specifi cations" on page 6 . The pressure
check should be made with the burner alight and at its
highest setting. See "Appendix A - Lighting Instructions
Plate" on page 36 for full lighting details.
