Economical and Efficient

• Puts the heat where it is needed
• Heats the air inside the engine
• Uses about 300 Watts (less than the price of a cup of coffee a day!)
• Warms the engine oil from subzero to safe starting temperature in less than one hour
• Thermally conductive adhesive for efficient heat transfer and lower surface temperatures
  • Extra adhesive also sold separately. Use 00 GLUE KIT for P/Ns 700 and 705, and 20 GLUE KIT for P/N 720 kits. 
• Bonded heatsink distributes heat evenly
• Reduces costly starter and engine abuse during cold weather starts

Safe

• UL recognized components. 100% thermal fused element
• External ground wire grounds the engine and airframe to the electrical outlet, reducing the risk of electrical shock in damp outdoor locations
• Thermostatically controlled to maintain oil sump temp less than 160 degrees F
• No flame or hot air to burn cowling or plastic parts
• Reduces the risk of fires associated with cold starts
• Ground Fault Circuit Interrupter (GFCI) included to reduce the risk of electrical shock and power surge damage 

Cautions:

• Do not plug engine heater in before installation. Heater will be damaged.
• Do not use without the 709 Ground Fault Circuit Interrupter.
• Do not neglect your heater. Periodically inspect for proper grounding, security and cord condition.
