Gas Supply Installation - Valor Horizon 534JLN Installation & Owner's Manual

•• The gas supply pipe should enter the appliance
case through the opening at the left side. The supply
pipe should be connected to the appliance gas inlet
pipe situated at the left side of the control valve.
Supply line connection to the inlet pipe is 3/8 inch
NPT ( female).

If the circulating fan is to be installed, be aware
that the supply pipe run inside the case should
be at the same height as the appliance inlet pipe
in order to clear the fan. If intending to fi t an
internal isolating valve, check that it will be clear
of the fan.
•• 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 suf 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 propane gas. Sealant
should be applied lightly to male threads to ensure
excess sealant does not enter gas lines.
•• The supply line should include a manual shut-off
valve to allow the appliance to be disconnected for
servicing.
•• A plugged 1/8 inch NPT tapping must be installed
in the line. The tapping must be accessible for test
gauge connection and be immediately upstream of
the gas supply connection to the appliance.
•• 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 (3.5kPa).

•• The minimum supply pressure is given in the
Specifi cations section of this manual.
•• All piping and connections must be tested for leaks
after installation or servicing. All leaks must be
corrected immediately.

•• The pressure test tapping locations are shown
below. A built-in non-adjustable regulator controls
the burner manifold pressure. The correct pressure
range is shown in the table in Specifi cations section
of this manual. The pressure check should be made
with the burner alight and at its highest setting. See
Lighting Instructions section for full operating details.
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 piping system at
test pressures equal to or less than 1/2 psig
(3.5kPa).
Failure to either disconnect or isolate the
appliance during pressure testing may result in
regulator or valve damage. Consult your dealer
in this case.
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.
