Beckett 30388 Auxiliary Limit Disc 130F Furnace Vent

Product Description

The BECKETT 30388 is an auxiliary limit disc rated at 130 degrees F, designed for use in oil-fired warm air furnace chimney vent applications. This disc functions as a thermal safety device, interrupting the circuit when flue or vent temperatures exceed the rated threshold to protect the system from overheating conditions. Finished in black oxide, the 30388 is a direct OEM-style replacement component installed by licensed HVAC technicians servicing oil-fired residential heating equipment. Its role in the venting system makes accurate temperature rating critical to proper system protection.

This auxiliary limit disc is specifically used on LRF and LRFV series oil-fired warm air furnaces with chimney vent configurations. It is typically installed in residential heating systems where oil-fired equipment is vented through a traditional masonry or metal chimney. HVAC technicians servicing these furnace models rely on this component to maintain safe vent temperature thresholds during heating operation.

Key Features

• Rated at 130 degrees F for precise thermal cutoff protection
• Black oxide finish for corrosion resistance in warm air vent environments
• Auxiliary limit function protects against vent overtemperature conditions
• OEM-style replacement for LRF and LRFV series furnace chimney vent systems

Compatibility

Designed for use on LRF and LRFV oil-fired warm air furnace chimney vent systems as specified by the manufacturer.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always shut down the furnace and allow the system to cool completely before servicing any limit or safety components in the vent system. Verify the replacement disc matches the original temperature rating before installing, as an incorrect rating can compromise system safety. Refer to the furnace service manual and applicable local codes for proper installation procedure.
