The 709SK GFCI Service Kit is a safety upgrade for the SAFE-HEET line of engine heaters or any other silicone pad engine heater. The kit provides ground fault and surge protection and all appropriate placarding and instructions for compliance with McFarlane Service Bulletin SB-3.

The addition of one 709 Ground Fault Circuit Interrupter and surge protector in every SAFE-HEET now makes our engine heater the safest unit available. With ground fault and surge protection the chance of dangerous and undetected lightning and mechanical damage that could cause lethal electrical shocks or engine damage is eliminated. SAFE-HEET uses U.L. recognized components and a 100% thermal fused element. The element itself shuts down the flow of electricity if any point on the element overheats. SAFE-HEET is thermostat controlled to maintain oil sump temperature less than 160 deg F. There is no flame or hot air to burn paint or plastic parts. The risk of fire associated with cold starts is reduced. 


Features and Benefits:

  • Reduces electrical shock hazards in wet or damp environments
  • Helps protect your engine heater and engine against electrical surges and lightning damage
