Connect Electrical Supply Final Check Important Notes for Gas Connection: • The appliance and its individual gas shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5kPa). • 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 1/2 psi (3.5kPa). Before connecting 5-foot (1.5 m) supply cord to wall receptacle, make certain that gas shutoff valve and all burner controls are in OFF position. After electrical connection is complete, place each burner cap in correct sized notched position and check operation of electric igniters. Check flame characteristics. Flame should be blue with no yellow tip. Yellow Flames: Further adjustment is required. Yellow Tips on Outer Cones: Normal for LP Gas. Soft Blue Flames: Normal for Natural Gas. If the flame is completely or mostly yellow, verify that the regulator is set for the correct fuel. After adjustment, retest. Some yellow streaking is normal during the initial start-up. Allow unit to operate 4-5 minutes and re-evaluate before making adjustments.
