7.21 Engine Preheater

The Reiff preheat system for Rotax 912 and 914 aircraft engines is an engine-mounted electric
preheat system designed for easier cold-weather starts. The preheat system consists of a 100 W
metal hot-strip element, which is epoxied to the bottom of the crankcase, and a 50 W band heater
that is clamped to the oil tank.
o
The Reiff is FAA approved, and includes a thermostat to keep the oil from exceeding 150 F.
The connector for the heater/charger is located on the lower left side of the fuselage, where the
lower cowling vent is:
To use the preheater, attach the extension cord to the connector and a wall outlet. The heater can
be used continuously (not recommended), with a timer, or with a GSM power switch at least an
hour before flight. It is also recommended to put a blanket on top of the engine cowlings to lower
the heat loss and improve preheating efficiency.
