Testing the GAS Supply System

As of 7/11/90, the gas pressure regulator is NOT factory installed. The regulator for this gas type is sealed within a plastic bag attached to the oven rack inside the oven cavity. This regulator must be field installed by a qualified installer.

Natural gas regulators are preset for 3.7" W.C. (Water Column) (.92 kPa); propane gas regulators for 10.0" W.C. (2.5 kPa)

1.Locate 3/4" (19 mm) gas connection pipe extending from rear of range.

2.Cover pipe threads with leak sealant.

3.Screw regulator hand-tight onto pipe with regulator arrow pointing towards range body back (Fig. 12).

4.Using pipe wrench, tighten regulator securely in an upright position (Fig. 12).

The arrow on the regulator shows the direction of the gas flow (Fig. 12). The pressure regulator must be mounted horizontally to ensure proper preset outlet pressure. If the regulator is installed in any other position, the outlet pressure must be reset for proper operation.

A leak limiter is supplied with every regulator to allow excess gas pressure to escape. Do not obstruct leak limiter on gas pressure regulator, as obstruction may cause regulator to malfunction.

WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

Before operation, verify thermocouple is securely seated in the safety valve. The thermocouple should be tightened a 1/4 turn past finger tight. DO NOT OVERTIGHTEN. Overtightening may damage the thermocouple or safety magnet.

When gas supply pressure exceeds 1/2 psig (3.45 kPa), the range and its individual shutoff valve must be disconnected from the gas supply piping system.

When gas supply pressure is 1/2 psig (3.45 kPa) or less, the range should be isolated from the gas supply system by closing its individual manual shutoff valve until the range is ready for start-up.
