Fig. 4d Fig. 4e the 1/2" flare union adapter with an adjustable wrench before tightening the gas supply fitting and/or appliance conduit (Refer to Fig. 4e). d) Installflare union adapter to external manual shut-off valve. e) Attach appliance conduit to flare union on shut-off valve. f) Make cure service shut-off valve on pressure regulator is in the "ON" position (See Fig. 4f). g) Check for leaks. Turn the gas supply on to the range and use a liquid leak detector at all joints and conduits to check for leaks in the system. Do not use flame to check for gas leaks. Checking Manifold Gas Pressure Disconnect the range and itsindividual shut-off valve from the gas supply piping system during any pressure testing of that system at test pressures greater than 14" of water column pressure (approximately 1/2" psig). 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 14" of water column pressure (approximately 1/2" psig). If it should be necessary to check the manifold gas pressure, connect manometer (water gauge) or other pressure device to the top burner right rear orifice. Using a rubber hosewith inside diameter of approximately 1/4," hold tubing down tight over orifice. Turn burnervalveon. Foran accurate pressure check have at least two (2) other top burners burning. Be sure the gas supply (inlet) pressure is at least one inch above specified range manifold pressure. The gas supply pressure should never be over 14" water column. When properly adjusted for Natural Gas the manifold pressure is 4." (For LP/Propane Gas the manifold pressure is 10.") Fig. 4f DO NOT allow regulator to turn on pipe when tightening fittings. a) Install an external manual gas shut-off valve to gas supply line in an accessible location outside of the range. Be sure you know where and how to shut off the gas supply to the range. b) Install 1/2" flare union adapter to pressure regulator using NO MORETHAN 15ft./Ibs. of torque NOTE: Be sure to stabilize the left side of the pressure regulator with adjustable wrench before tightening ANY fittings to the pressure regulator (Refer to Fig. 4d). c) Tighten the gas supply fitting and/or appliance conduit to flare union on the right side of the pressure regulator using NO MORETHAN 15ft./Ibs. of torque.Be sure to stabilize 5. Read these electrical connection details first then connect electricity to range. Before servicing, disconnect electrical supply at circuit breaker, fuse or power cord. Electric Requirements: A dedicated, properly grounded and polarized branch circuit protected bya 15amp. circuit breaker or time delay fuse. See serial plate for proper voltage. Extension Cord Precautions: Because of potential safety hazards under certain conditions, we strongly recommend against the use of any extension cord. However, if you still elect to use an extension cord, it is absolutely necessary that it be a UL listed 3-wire grounding type appliance extension cord and that the current carrying rating of the cord in amperes be equivalent to or greater than the branch circuit rating. Such extension cords are obtainable through your local service organization.
