PRESSURE TESTING
Manifold pressure should be checked with a manometer using the following instructions:
1
Remove the injector from the rear left (or rear right) burner and mount the test point
adapter (available from the After-Sales service).
2
Turn the burner control knob to the maximum position.
3
Press the knob and keeping it pressed check the manifold pressure with a manometer.
NATURAL gas requires 4.0” (101.6mm) W.C.P. and LP/PROPANE requires 11.0” (279.4mm)W.C.P.
IMPORTANT!
●
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” (355.6mm)
W.C.P). If the line pressure is in excess of that amount, a stepdown regulator will be required.
●
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).
●
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). W.C. for natural gas or 12.0” for LP.
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 damage the flexible connector when moving the range.
●
The pressure regulator has 1/2” (12.7mm) 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.
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.

LEAK TESTING
●
Make sure all oven and burner knobs are set to OFF before connecting range to gas supply.
●
After final gas connection is made, turn gas supply on and test all connections in gas supply piping for gas leaks with
a soapy water solution.
●
In order to avoid property damage or serious personal injury, never use a Iighted match or open flame.
If a leak is present, tighten joint or unscrew, apply more joint compound, tighten again and retest connection for leak.
