Reznor 112754 Blocked Flue Switch Manual Reset L175F

Description

Reznor 112754 Blocked Flue Switch — Manual Reset, L175F

The Reznor 112754 is a blocked flue safety switch designed to protect heating equipment from hazardous flue blockage conditions. When a restricted or obstructed flue is detected, this switch opens at 175°F to interrupt the burner circuit, preventing unsafe operation and potential heat exchanger damage. The manual reset (M/R) design requires a deliberate technician reset after a trip event, ensuring the root cause of the blockage is identified and corrected before the unit is returned to service.

Key Features

• Opens at 175°F (L175F) to protect against blocked or restricted flue conditions
• Manual reset (M/R) operation — requires intentional reset after trip for added safety
• Direct OEM replacement part for compatible Reznor heating equipment

• Designed for reliable, long-service performance in commercial and industrial heating applications

Application
