Non-PV Wiring Diagram
While the burner does not require a 120 V A.C. power supply, it is highly recommended as a primary power source. Batteries (4 AA) should be used as a
secondary power source only.
• Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous
operation.
• Ensure that the wires do not touch any hot surfaces and are away from sharp edges.
• This appliance is equipped with a three-prong (grounding) plug for protection against shock hazard and should be
plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from
the plug.
• Electrical power must be brought to the appliance by a licensed electrician. Do not cut the ground terminal off under
any circumstances.
