Introduction

The "Red Dragon" is a propane fired portable heater designed to preheat aircraft. It consists of a propane tank, 12v blower, 12v automotive battery, and a charger mounted to a dolly. If the heater is started at the beginning of the preflight, the engine should be sufficiently warm by the end of the preflight. More time may be needed for easy starting on very cold/windy days or if you do a lousy/quick preflight.

Instructions

• Unplug the heater.
• Carefully wheel the heater to the aircraft to be preheated.
• Turn on the blower.
• Turn on the propane at the tank.
• Hold the thermocouple down and keep holding it down for 30 seconds after lighting.
• Push the igniter until it lights.
• Direct the hose into the cowl hole of the aircraft.
• Allow the heater to work while you preflight the aircraft.
• When done preheating, turn off the propane at the tank.
• When the flame dies, turn off the blower.
• Wheel the heater back into the hanger.
• Plug the heater back into 120v power.

Warnings

• Be sure to keep the heater away from any fuel sources or spilled fuel.
• Do not use the heater to deice any aircraft.

Troubleshooting

• The blower and fan cut off while the heater in use.
  • The battery may have died. If this happens repeatedly, advise maintenance to replace the battery.
