b. Any conversion required must be performed by your dealer or a qualified licen-
sed technician or gas service company. Please provide the service person with
this manual before work is started on the range. (Gas conversions are the re-
sponsibility of the dealer or end user.)
c. This range can be used with NATURAL or LP/PROPANE gas. It is shipped from
the factory adjusted for use with NATURAL gas.
d. Manifold pressure should be checked with a manometer and by operating as
below detailed:
•
Remove the injector from the rear left (or rear right) burner and mount the
proper test point adapter which is available from the After-Sales Service
(see side figure and the “OPERATIONS TO BE PERFORMED WHEN SUB-
STITUTING THE INJECTORS” chapter).
•
Turn the rear left (or rear right) burner control knob to the maximum posi-
tion.
•
Press the knob and keeping it pressed check the manifold pressure with a
manometer; NATURAL gas requires 4.0” W.C.P. and LP/PROPANE requires
11.0” W.C.P.
•
Incoming line pressure upstream from the regulator must be 1” W.C.P. hi-
gher than the manifold pressure in order to check the regulator.
•
The regulator used on this range can withstand a maximum input pressure
of 1/2 PSI (14.0” W.C.P). If the line pressure is in excess of that amount, a
stepdown regulator will be required.
e. The appliance, its individual shut-off valve, and pressure regulator must be di-
sconnected from the gas supply piping system during any pressure testing of
that system at pressures in excess of 1/2 PSI (3.5 kPa).
f. 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 pressure equal to or less than 1/2 PSI (3.5 kPa).
3. Flexible Connections:
If local codes permit, CSA or UL design-certified, flexible metal appliance connector
is recommended for connecting this range to the gas supply line. Do Not kink or da-
mage the flexible connector when moving the range. The pressure regulator has 1/2”
NPT female pipe threads.You will need to determine the fittings required, depending
on the size of your gas supply line, flexible metal connector and shutoff valve.
4. Rigid Pipe Connections:
If rigid pipe is used as a gas supply line, a combination of pipe fittings must be used to
obtain an in-line connection to the range. All strains must be removed from the supply
and fuel lines so range will be level and in line.
•
Use joint compounds and gaskets that are resistant to action of natural or propa-
ne gas on all male pipe threads.
•
Do not over tighten gas fitting when attaching to pressure regulator. Over tighte-
ning may crack regulator.
5. Leak Testing:
IMPORTANT: Leak testing of the appliance shall be conducted as follows:
•
After final gas connection is made, turn on manual gas valve and test all con-
nections in gas supply piping and appliance for gas leaks with a soapy water
solution. During this test all appliance gas valves have to be closed.
•
In order to avoid property damage or serious personal injury, never use a Iighted
match. If a leak is present, tighten joint or unscrew, apply more joint compound,
tighten again and retest connection for leak.
