Valor VENTANA 1200EAN Installation & Operating Instructions Manual page 25

The unit is supplied with a manual shut-off valve and
stainless steel flex line to allow the appliance to be
disconnected for servicing. The flex line and shut-off valve
are supplied loose to avoid damage during shipping.
Connect the assembly to the appliance regulator as shown
below ensuring that the pressure test tap on the valve is
accessible for future use.
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 piping 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.The unit is supplied with a manual shut-off valve
and stainless steel flex line to allow the appliance to be
disconnected for servicing. The flex line and shut-off valve
are supplied loose to avoid damage during shipping.
Connect the assembly to the appliance as shown below.
Pressure Test Points
The minimum supply pressure is given in the section Ratings of this
manual—page 7.
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 flame to check
for leaks.
Correct any leak detected
immediately.
The pressure test tapping locations are shown in the figures on the
right. An internal regulator within the valve controls the burner manifold
pressure. The correct pressure range is shown in the table in section
Ratings of this manual on page 7. 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 39.
