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
connections 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.
b) Any conversion required must be performed by your dealer or a qualified licensed
plumber or gas service company. Please provide the service person with this
manual before work is started on the range. (Gas conversions are the responsibility
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 front left 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 SUBSTITUTING THE INJECTORS”
chapter).
-Turn the front left burner control knob to the maximum position ( position)
-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. higher
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 step-
down regulator will be required.
e) The appliance, its individual shut-off valve, and pressure regulator must be
disconnected 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 design-certified, flexible metal appliance connector is
recommended for connecting this range to the gas supply line. Do Not kink or damage
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
propane gas on all male pipe threads.
Do not over tighten gas fitting when attaching to pressure regulator. Over
tightening may crack regulator.
TEST POINT ADAPTER
The Test Point adapter is available
from the After-Sales Service.
