MARS 34616 Kit

For field technicians and mechanical contractors tasked with electric furnace repair, the MARS 34616 Kit provides a high-reliability solution for restoring failing heating assemblies. This 2500W heating element restring kit is engineered for versatility, delivering 2500W at 240V or 1875W at 208V, making it compatible with a broad range of HVAC strip heaters and residential air handlers. The kit features a high-grade, close-wound nichrome resistance coil designed to be stretched to the specific length required for your heater frame. Unlike generic alternatives, this MARS 34616 replacement includes welded terminal bolts to ensure low-resistance electrical connections, significantly reducing the risk of terminal burnout under heavy electric heat loads. The comprehensive package comes with essential ceramic insulators and bushings in multiple sizes (.375 and .450 inch) to accommodate various mounting hole diameters, providing a professional-grade finish that meets rigorous field standards.

• Universal Compatibility: Optimized for use in electric furnaces and heat pump backup systems across multiple brands.
• Durable Construction: Heavy-duty resistance wire with welded terminals prevents typical failure points at connection blocks.
• Field-Adaptable: The stretch-to-length heater coil allows for precise fitting in diverse plenum and housing configurations.
• Complete Hardware Set: Includes male and female insulators, standard and extra-long bushings, and necessary mounting hardware for immediate installation.
• Efficiency: Provides a cost-effective alternative to replacing entire heating element banks, reducing truck stock requirements.

How do I determine the correct stretch length for the coil?
Measure the original coil's path across the insulators in the heater frame. Stretch this restring kit uniformly to match that exact footprint, ensuring even spacing between turns to prevent hot spots and premature failure.

Can this kit be used in 208V commercial applications?
Yes, this heating element replacement is rated for 1875W when operated at 208V, providing reliable performance in light commercial air handling units and VAV boxes.

What causes original coils to burn out?
The most common causes include restricted airflow resulting from dirty filters, failing sequencers that keep elements energized too long, or loose terminal connections leading to high-resistance arcing.
