Description

This thermocouple monitors the burner flame and works with the safety valve. It allows gas flow only while a flame is present and lets the valve close when no flame is detected, helping restore dependable burner operation.

• Senses burner flame heat and sends a small millivolt signal to the safety valve
• Works with the flame-failure safety system to maintain or cut gas flow based on flame presence
• Common symptoms can include: burner lights but goes out when the knob is released; needing to hold the knob down unusually long to keep the burner lit

Install notes:

• Disconnect power and shut off gas before servicing
• Allow the unit to cool; remove grates/caps to access the sensor tip and route the lead to the valve connection as originally installed
• Do not kink or sharply bend the lead; position the tip within the burner's flame envelope
• After reassembly, restore gas/power and test burner operation
